Food Contact and Compliance for Copper Cookware

Copper cookware sold into the European Union is governed by the general inertness requirement of Regulation (EC) No 1935/2004, because no EU-wide specific measure has ever been adopted for metals and alloys. In the United States the FDA Food Code restricts bare copper in contact with acidic food. Tin lining is what makes a copper cooking surface workable.

The EU framework, in plain terms

Regulation (EC) No 1935/2004 is the framework law for every material intended to touch food in the European Union. Its Article 3 requires a material to be inert enough that it does not endanger health, change the composition of the food unacceptably, or spoil its taste and smell. That duty applies to metal whether or not any further rule exists.

The governing text is Regulation (EC) No 1935/2004 on materials and articles intended to come into contact with food. Its Article 3 sets a general requirement: a material must be inert enough that it does not transfer substances to food in quantities that could endanger health or change the food unacceptably. That obligation applies directly, whether or not any further rule exists for the material.

Here is the part that surprises most buyers. Under Article 5 the Commission may adopt specific measures for individual material groups, and it has done so for a short list — plastics, ceramics, regenerated cellulose film, and active and intelligent materials. Metals and alloys are not on that list. There is no EU-wide specific measure for metal cookware, and therefore no EU-wide legal requirement for a Declaration of Compliance the way there is for plastics.

That is not the same as “no rules apply”. Article 3 still binds. Member states legislate in the gap, and commercial buyers routinely ask for a declaration and a test report as a condition of purchase even where no statute names one. The Council of Europe, through its European Directorate for the Quality of Medicines and HealthCare, publishes a technical guide on metals and alloys in food contact with recommended release limits; it is not EU law and it is not binding, but many national authorities and laboratories treat it as the working reference.

Article 3, and what “inert enough” means in practice

Article 3 sets three tests rather than one. A food contact material must not transfer constituents to food in quantities that could endanger human health, must not bring about an unacceptable change in the composition of the food, and must not cause a deterioration in its taste or smell. All three apply to a copper pan simultaneously.

The third test is the one people forget, and for copper it is often the first to fail. Metal picked up by an acidic food changes how the food tastes long before it reaches a level anybody would call a health question. A sauce that goes metallic in a bare copper pan is failing the organoleptic limb of Article 3, not merely disappointing the cook.

The second test — unacceptable change in composition — is the reason acidic and salty foods sit at the centre of every copper discussion. Vinegar, tomato, citrus, wine and brine attack bare copper far faster than a neutral food does, and contact time compounds it. A short sear is not the same exposure as a stew left in the pan overnight, and the regulation is framed around “normal or foreseeable conditions of use”, which includes the overnight case whether or not anyone intends it.

The first test — health — is where the numbers live, and where a laboratory rather than a supplier has to answer. Copper is an essential trace element and a nutrient at low intake; that is exactly why the question is about quantity and not about presence. Anyone telling you copper is either universally safe or universally dangerous is arguing about the wrong thing.

Two horizontal rules travel alongside Article 3 and do apply to metals. Good manufacturing practice for food contact materials is required by its own regulation and is not limited to the groups with specific measures. And the framework’s labelling and traceability provisions apply too: articles intended for food contact carry either the glass-and-fork symbol or wording to that effect unless their use is obvious, and businesses in the chain have to be able to identify who they bought from and who they sold to.

Why there is no EU-wide specific measure for metals

Metals and alloys appear in the framework regulation’s annex as a group for which the Commission could adopt a specific measure, but no such measure has been adopted. The result is that plastics, ceramics, regenerated cellulose and active and intelligent materials have detailed EU rules and their own declaration duties, while metal cookware is governed by the general principle alone.

This is a gap in the law rather than an exemption from it, and the distinction matters commercially. Sellers occasionally read “no specific measure” as “unregulated” and say so out loud. That reading does not survive contact with a market authority, because Article 3 is directly applicable and enforceable on its own terms.

The practical consequence for a buyer is that there is no single European document to ask for. With plastics you can ask for a Declaration of Compliance and there is a regulation that says what has to be in it. With metals there is no equivalent template in EU law, which is why buyers end up asking for a laboratory report instead — a substitute for the missing regulatory instrument rather than a legal requirement in its own right.

It is also why a supplier claiming a copper pan is “EU approved” is describing something that does not exist. There is no EU approval mechanism for cookware, no European authority that issues one, and no certificate that could be shown. Where a supplier offers such a document, the useful next question is what body issued it and against which standard.

The Council of Europe guide on metals and alloys

The Council of Europe publishes a technical guide on metals and alloys used in food contact, developed through its pharmacopoeia directorate. It recommends specific release limits for the individual metals of interest, copper and tin among them, and describes the test conditions used to check them. It is guidance, not legislation.

Its standing is worth understanding precisely, because buyers cite it as though it were binding and suppliers dismiss it as though it were nothing. Neither is right. It is a voluntary instrument, adopted through a Council of Europe resolution and maintained as a technical guide, and no member state is obliged to transpose it. In practice, though, it is the only detailed European technical reference that exists for this material group, so accredited laboratories test against it and national authorities lean on it when they need a yardstick.

That gives it real commercial weight. If your buyer asks for evidence that a copper pan behaves acceptably in food contact, the report you will be offered by a European laboratory will very likely be framed against this guide, using an acidified simulant standing in for acidic food and a defined contact time and temperature. Knowing that in advance lets you specify what you want tested rather than accepting whatever a supplier happens to hold.

The guide also deals with coatings and linings explicitly, which is the part relevant to tinned copper: what matters is the surface the food actually meets, and the integrity of that surface over the life of the article.

National rules inside the EU gap

Where the European Union has adopted no specific measure, member states may legislate nationally, and several have. That is why a copper article can be perfectly acceptable in one EU market and meet a documentary demand in another, and why “compliant with EU law” is not a meaningful answer on its own.

Germany is the country buyers meet first and it gets its own section below. France, Italy, the Netherlands and others operate their own national provisions or published guidance for metals, and the detail differs. The mutual recognition principle mitigates some of this, but it does not remove a buyer’s practical need to satisfy the authority in the market where the goods are actually placed.

The consequence for an importer is simple and slightly unwelcome: the question is never “is this EU compliant?” but “what does my market ask for, and can this supplier evidence it?”. If you are distributing across several member states, the strictest of them sets your documentation, not the average of them.

Nothing about this is specific to Turkish copper. A French or Italian copper pan crossing the same border meets exactly the same framework, the same absence of a specific measure and the same national patchwork.

What a Declaration of Compliance actually contains

A Declaration of Compliance is a written statement by the business placing an article on the market that the article meets the applicable food contact requirements. For plastics its content is prescribed by EU law. For metals no template exists, so what circulates commercially is a declaration modelled on the plastics one and backed by a laboratory report.

A useful declaration for a metal article names the issuing business and its address, identifies the article precisely enough to tie it to a specific item and a specific production, states the materials of every part that meets food, states the legislation and guidance it is declared against, states the conditions of use it covers — food types, temperature, contact time — and references the test report that supports it, by report number and date.

The condition of use is the clause that gets skipped and the clause that matters. A declaration covering neutral foods at room temperature says nothing at all about a tomato sauce simmered for an hour. If your buyer’s use is acidic and hot, the declaration has to say so, or it is not about your use.

It is also worth being clear about who issues it. In the plastics regime the duty sits with each business in the chain, and the business that places goods on the EU market is the one whose declaration the authority will ask to see. A declaration from a supplier outside the European Union is an input to yours. It is not a substitute for it, and a distributor who files a foreign supplier’s paperwork and assumes the duty is discharged has misread the structure.

Germany, and the “LFGB certificate” that does not exist

German buyers ask for LFGB documentation more often than any others, and the phrase “LFGB certificate” is a misnomer. No German authority issues one. What exists is a test report from an accredited laboratory using the official methods, plus a declaration of conformity written by the business placing the goods on the market.

The Lebensmittel- und Futtermittelgesetzbuch is the German food and feed code. Its §30 prohibits producing or placing on the market food contact articles in a way that harms health, and §31 ties the requirement directly back to Article 3 of 1935/2004.

There is no government body that issues an “LFGB certificate”. What exists is a test report from an accredited laboratory, testing to the methods collected under §64 LFGB — typically sensory transfer of odour and taste, alloy composition, and extractable heavy metals under defined food simulants. On the strength of that report, the manufacturer or importer writes its own declaration of conformity. So when a buyer says “we need LFGB”, what they need is a laboratory report plus a declaration, not a certificate from an authority.

The sensory test deserves a note of its own, because it is the German element that catches importers out. It is a panel test: trained assessors judge whether water or another simulant held in contact with the article picks up a detectable off-odour or off-taste, and they score it. It is subjective by design and it is the test that copper and its linings most often stumble over, ahead of any metal release figure. If you are commissioning testing for the German market, expect it to be included and expect it to be the one that decides the outcome.

The German federal risk assessment institute publishes recommendations for several food contact material groups, and its opinions are frequently cited by laboratories. Like the Council of Europe guide, they are not statutes; they are the technical reference that a report will be written against.

A word on how the phrase gets used in trade. “LFGB certified” appears constantly in supplier listings, particularly in listings aggregated from outside Europe. It is not a status any authority confers. When you see it, the productive question is: which laboratory, which report number, which methods, which article, and what date — because a report is issued against a specific article and a specific production, and a report about a different item is not about yours.

The United States

The FDA does not approve consumer cookware, and no certificate of FDA approval exists for a copper pan. What does exist, and what commercial buyers work to, is the FDA Food Code — a model code adopted by states for retail food establishments — together with state-level rules such as California’s Proposition 65 warning law.

The FDA does not approve consumer cookware, and no supplier can hand you an “FDA approved” certificate for a copper pan, because the document does not exist. Anyone offering one is describing something else.

What does exist, and matters for commercial kitchens, is the FDA Food Code. Section 4-101.14 states that copper and copper alloys such as brass may not be used in contact with food that has a pH below 6 — vinegar, fruit juice, wine — with a carve-out for brewing before and during fermentation. The Food Code is a model code that states adopt for retail food establishments; it is not a federal statute and it does not govern what a consumer may own. If you are selling into restaurants, your buyer will know this section, and a tin lining is the reason a copper pan can be used at all.

California adds Proposition 65, which is a warning law rather than a ban: if a listed chemical such as lead is present above the relevant level, a warning is required. Brass components — handles, knobs, feet — are the usual reason this comes up with metal cookware. The FDA has also been actively warning about lead leaching from some imported metal cookware, so expect the question and do not be offended by it.

Underneath all of this sits the general prohibition in the federal food law on adulterated food, which is the mechanism by which a leaching vessel becomes a legal problem in the United States rather than merely a bad product. There is no pre-market approval step for a pan; there is a general duty and an enforcement power.

Food Code 4-101.14 in a working kitchen

Food Code section 4-101.14 is the provision a US health inspector actually applies to copper. It prohibits copper and copper alloys in contact with food below pH 6 in a retail food establishment, which covers most of what a restaurant kitchen cooks. Tin lining removes the copper from the food surface and is the reason tinned pans remain usable.

Read carefully, the section is about the surface that meets the food, not about the metal the vessel is made of. A copper body with an intact tin lining does not put copper in contact with the food. A copper body whose lining has worn through does — and at that point the same pan that passed inspection last year does not.

That has a maintenance consequence that most buyers of copper for hospitality underestimate. Tin is a wear layer. In a working kitchen with metal utensils and daily heat cycling, it wears faster than it does at home. Retinning is normal, planned maintenance, and a venue buying copper for service should budget for it rather than treat it as a failure.

It also shapes what to buy for which job. Serving pieces, trays, drinkware for cold or neutral drinks and presentation copper live nowhere near this provision in the way a saucepan does. Buyers whose interest is the look of copper on the pass, rather than acid cooking in copper, meet a much simpler set of questions.

Two further points that come up in American enquiries. The carve-out in the section for brewing before and during fermentation is narrow and specific; it is not a general permission for bare copper with acidic liquids. And the Food Code is a model — the version in force is the one your state or county adopted, which may lag the current federal model by several revisions. Your local health department, not a supplier, is the authority on which text applies to your premises.

NSF: what it is, and what it is not

NSF is an independent certification body, not a government agency, and its food equipment standards are the benchmark many US health jurisdictions use for commercial kitchen equipment. Certification is voluntary in law but often mandatory in practice, because local codes commonly require food equipment to be certified to an accredited standard.

The distinction between “not legally required” and “you will not get it past your inspector” is where American buyers and overseas suppliers most often talk past each other. A supplier can say truthfully that no law obliges a pan to be certified. The buyer opening a restaurant can say equally truthfully that the equipment schedule will not be signed off without it. Both statements are correct and they are about different things.

What certification involves is a materials and construction assessment against a published standard, followed by audits of the production facility, with the mark applied to certified items. It is a programme rather than a one-off test, and its cost and duration reflect that. That is the honest reason handmade copper from small workshops is rarely certified: the model does not fit a certification programme built around a factory with a stable, audited production line.

So the practical position, stated plainly: we do not hold NSF certification, and copper is not the right material for a US commercial kitchen that requires certified equipment. The way copper enters American hospitality is through the front of house — serveware, trays, coffee service, bar drinkware — where the certification question either does not arise or is far narrower. If your programme requires certified equipment, we are the wrong supplier for that part of it and we would rather say so at the enquiry than at the inspection.

Tin lining: why it is there

Tin lining exists because bare copper does not satisfy the performance requirement when it meets acidic or salty food. Tin isolates the food from the copper. It is a wear layer rather than a permanent coating, and it is renewed when copper starts to show through, which is normal maintenance rather than a defect.

No article of EU law says “copper pans must be tinned” in those words. The requirement is a performance one, and it comes out the same way: acidic and salty food in prolonged contact with bare copper dissolves metal into the food, so a bare copper cooking surface will not meet Article 3 when it is tested against an acidic simulant. Tin isolates the food from the copper. It is a wear layer, not a permanent coating, and it is renewed when the copper starts to show through — which is normal maintenance, not failure.

Two things follow for a buyer. A worn lining is a compliance question, not only a cosmetic one. And unlined copper has legitimate uses that are not cooking — the outside of a piece, decorative work, and vessels never intended for food.

Two further points that a careful buyer should raise, and that we would rather raise first. The composition of the tin itself is a laboratory question: historically some tinning practice used lead-bearing solder, and whether a given lining does is answered by a report and not by a sentence on a website. We do not assert a composition we have not had tested. And tinning is applied by hand in this craft, so coverage and thickness vary between pieces in a way they do not in an industrial coating. Both are reasons a buyer with a documentary requirement should commission testing on the actual production rather than accept a general assurance.

You will also read confident claims that bare copper is fine for particular foods — honey, jam, chocolate, egg whites. Some of those uses have a long tradition behind them. We are not going to repeat them as safety statements, because we have not seen the evidence that would let us stand behind one, and a claim about food safety is not a place for tradition to substitute for testing.

Decorative pieces sit outside the framework

Regulation 1935/2004 covers materials intended to come into contact with food. A candle holder, an incense burner, a vase or a planter is not intended for food, so declarations, migration testing and food contact labelling do not apply to it. General product safety law and chemicals law still do.

Regulation 1935/2004 covers materials intended to come into contact with food. A candle holder, an incense burner, a vase, a planter or a charger plate is not intended for it, so declarations, migration testing and the food contact labelling requirements do not apply. General product safety law still does, and the REACH duty to notify substances of very high concern above the threshold still does.

The honest line runs at how the piece is sold. Describing a decorative bowl as if it were tableware is where this goes wrong, and we mark decorative pieces as not intended for food contact rather than leaving it to be assumed.

Note the direction of travel, because it catches retailers rather than importers. Intention is judged partly by presentation. A decorative bowl photographed full of fruit, listed under tableware and sold next to serving dishes has been presented as food contact whatever the supplier’s paperwork says. If you are buying decorative copper, keep the listing consistent with the declaration you have; the listing is evidence too.

On chemicals law specifically: lead is on the European candidate list of substances of very high concern, and brass components are the usual reason a copper article contains any. Above the threshold, article suppliers owe information down the chain and a notification into the European waste database. That duty exists independently of whether the article ever touches food, so decorative pieces are not outside it.

What testing on copper actually involves

Food contact testing on a copper article is a laboratory exercise against defined simulants, contact times and temperatures, not a documentary formality. For tinned copper it usually combines metal release into an acidified simulant, an assessment of the alloy and coating composition, and — for the German market — a sensory panel test.

The first thing to settle is what is being tested. A report is issued against a specific article from a specific production. A report on a saucepan says nothing about a coffee pot, and a report from an earlier run says nothing certain about the current one if the workshop or the tinning has changed. Buyers who ask “do you have a report?” and accept a yes without those particulars have bought reassurance rather than evidence.

The second is the conditions. Testing is done at a stated temperature for a stated time with a stated simulant, chosen to represent the intended use. Results obtained with a mild simulant at room temperature do not transfer to hot acidic cooking. If your use is the demanding one, the test has to be the demanding one.

The third is cost and time, and this is where enquiries stall. Testing has to be commissioned, samples have to be sent, a laboratory queue has to be joined and a report has to be written. It is a matter of weeks rather than days, and it is charged per article family rather than per order. None of that is a reason not to do it. It is a reason to raise it at the enquiry stage rather than after a purchase order exists.

The fourth is who commissions it. It can be us, it can be you, or it can be a third party you both accept. Buyers who need the report for their own declaration frequently prefer to commission it themselves, from a laboratory they already use, precisely so that the chain of custody of the samples is theirs. We are comfortable with that and will supply the samples for it.

What we can give you, and what we cannot

Accurate technical information is what we can put in writing today: the material of every part, whether the food surface is tinned, the gauge, the dimensions and the intended use of each item. What we cannot supply today is a food contact test report, and we say so before an order rather than after it.

We can tell you the material, whether the food surface is tinned, the gauge and the dimensions, and we can put that in writing with the offer. Custom and marked work goes through a sample before a run, so you see the finish before the quantity is committed.

We do not hold a food contact test report today. If your market or your buyer requires one, say so at the enquiry stage: testing has to be arranged with a laboratory, it costs money and it takes time, and it is far cheaper to plan for at the start than to discover at a border. We would rather lose an order than promise a document we do not have.

We also do not claim purity figures, lead-free status or any certification we have not been given. Those are testable statements and an untested one is worth nothing to you.

What we will not do is send you somebody else’s report with our name on it. That practice is common enough in this trade that it is worth naming: a report about a different article, from a different workshop, in a different year, is not evidence about the goods in your carton, and passing it off as such is the kind of thing that ends a supply relationship at an inspection rather than at a meeting.

If your buyer requires documentation

Buyers with a documentary requirement should send it at the enquiry stage in the form their own customer stated it. The useful details are the destination market, the exact articles, the intended food types and temperatures, whether a report or a declaration is wanted, and whether a particular laboratory is specified.

From that we can answer three things quickly. Whether the requirement is one that testing can meet at all for the articles you want. Roughly what commissioning it involves in time. And whether the articles themselves should change — because in several cases the honest answer has been that a different piece from the range, or a decorative rather than a cooking item, removes the requirement entirely instead of satisfying it.

What we ask in return is that the requirement arrives before the order rather than after it. Every difficult version of this conversation we have had began the same way: goods ordered, goods produced, and only then a message explaining that a customer needs a report. At that point the options are all expensive.

The customs and paperwork side of the same shipment — commodity codes, origin documents, who lodges the entry — is set out separately on importing copper cookware from Türkiye.

Compliance questions buyers ask

Compliance questions about copper cookware fall into four groups: what the European Union requires, what Germany means by LFGB, what applies in the United States, and what documentation a supplier can actually produce. The answers below are the ones we give most often, and they include the ones we would rather not have to give.

Do I need a Declaration of Compliance to import copper cookware into the EU?

There is no EU-wide specific measure for metals, so the DoC obligation that applies to plastics does not apply in the same way. Article 3 still binds, national rules differ, and most commercial buyers ask for a declaration anyway. Confirm with your own adviser for your market.

Who is responsible for compliance — you or us?

The business that first places the goods on the market in the destination — normally the importer or distributor established there — carries the duty, and the labelling rules ask for a name and address inside that market. Our part is that the goods are what we say they are and that you get accurate technical information about them.

Is your copper food safe?

Every surface intended to meet food in our range is tin lined, which is what keeps food off the copper. We describe that as a construction fact, not as a guarantee, because a guarantee would need a test report behind it and we do not have one yet.

Is there such a thing as an LFGB certificate?

No. No German authority issues one. What a German buyer needs is a test report from an accredited laboratory using the official methods, plus a declaration of conformity written by the business placing the goods on the market. A listing that says “LFGB certified” is using a phrase that does not correspond to any document an authority issues.

Can you supply an FDA approved certificate?

No such certificate exists for cookware, so nobody can. The FDA does not approve pans. What applies commercially in the United States is the Food Code adopted by your state, and for equipment in a commercial kitchen, certification to an accredited standard by an independent body.

Are your pieces NSF certified?

No. Certification is a programme with facility audits behind it, and hand workshops do not fit it. If your project needs certified equipment, copper serveware and drinkware may still work for you but copper cooking equipment will not, and we would rather tell you now.

Do the brass handles bring a lead question with them?

They can. Common brass grades are alloyed with lead for machinability, and that is what sits behind both the REACH notification duty and Proposition 65 warnings on metal goods. Handles are not a food contact surface, which reduces the exposure but does not remove the question. If it matters in your market, raise it with the enquiry and we will discuss what the pieces are made of before you order.

Is bare copper safe for honey, jam or chocolate?

We are not going to say yes. There is a long tradition behind unlined copper for some preserves and confectionery, and there is a difference between a tradition and a documented safety position. We have not seen evidence we could stand behind, so we do not repeat the claim, and every cooking surface in our range is tinned.

Does copper cookware need CE marking?

No. CE marking applies to defined product groups such as machinery, electrical equipment and toys. Cookware is not one of them, and a supplier offering a “CE certificate” for a pan is describing something that does not apply.

What about RoHS?

RoHS covers electrical and electronic equipment. Non-electrical cookware falls outside it.

How long does testing take if we decide to commission it?

Weeks rather than days, because samples have to travel, a laboratory queue has to be joined and a report has to be written against the article and the conditions you specify. It is charged per article family rather than per order. Raise it with the enquiry and it is a planning item; raise it after production and it is a problem.

Can you send documents with the shipment?

Commercial invoice, packing list and proof of origin, yes. Preparing export paperwork is a paid service and it covers the Türkiye side; the customs declaration in your country has to be made by a party established there, normally your broker.
