Packaging Compliance: Self-Declaration vs. Third-Party Certification — 3 Real Boundaries: China Self-Declaration / EU Declaration of Conformity / US Third-Party Testing — What a Printer Should Confirm First When Accepting an Order
💡 💡 At a Glance
Compliance systems for food-contact packaging differ across three markets, and printers often confuse test reports, Declarations of Conformity, and third-party certification. There are three real boundaries. First, three systems use three signing methods: China requires a manufacturer's self-declaration and retention of technical documentation under random regulatory inspection; the EU requires the manufacturer's own Declaration of Conformity (DoC), which is fundamentally a self-declaration that no organization can sign or replace on the company's behalf, so claims of an "EU packaging conformity certificate" are misleading; many US categories require a test report from a third-party laboratory, not an "FDA certification certificate." Second, these documents cannot replace one another: a report covers only the specified tests and samples, while a declaration cites data rather than generating it. The printer's most dangerous practice is arranging testing on the customer's behalf and filling in commissioning information and sample descriptions without verification, leaving the report disconnected from the mass-produced product without the customer's knowledge. Third, the printer's position differs by market: in China it produces technical documentation, including four categories of records delivered with the goods; in the EU it supplies upstream evidence; in the US it provides test samples. The first issue to confirm when accepting an order is whether the printer must provide technical support or issue a legally effective declaration. The latter boundary must be established in writing during the quotation stage.
In October 2026, an OEM customer assigned us two batches of work. They were the same printed box using the same food-contact paper, but the batch destined for the EU required a "Declaration of Conformity," while the batch destined for the US required an "FDA Test Report."
They asked us: "Can your printing company issue both?"
We replied: "We can provide technical support materials, but you must issue the declarations. And the two documents you are asking for are not the same type of document."
The customer said: "Aren't they both test reports?"
This question reveals a widespread misconception: in most people's experience, "compliance" means having a test report. However, in the Chinese, EU, and US markets, a test report, a Declaration of Conformity, and third-party certification are three different things. They are signed by different parties, based on different requirements, and have different legal effects.
The First Boundary: Three Systems, Three Signing Methods
First, these three regulatory pathways need to be separated.
China: self-declaration and document retention. Food-contact paper and paper products fall under a system in which enterprises in China make self-declarations of conformity. The manufacturer guarantees that the product complies with applicable mandatory standards and retains relevant technical documentation, including raw material information, process parameters, and inspection reports, for verification. Regulatory oversight is based on random inspections.
What Chinese customers normally require is straightforward: a stamped Declaration of Conformity and a technical documentation package. The documentation package is the core. It includes raw material inspection reports, ink conformity certificates, production process records, and batch inspection records. Printers often already hold most of these materials.
EU: a Declaration of Conformity (DoC), but not third-party certification. The EU approach requires the manufacturer, importer, or authorized representative to prepare the Declaration of Conformity. The declaration states that the product complies with EU regulations, principally the framework regulation and material-specific regulations for food-contact materials, and identifies the applicable regulations and test data. Technical evidence may come from any qualified laboratory, including a third-party laboratory.
The key point is that no "EU certification body" can sign this declaration on a company's behalf. The EU does not have a CE-like system in which an institution stamps and issues a certificate and the company simply applies the mark. A Declaration of Conformity is signed by the company itself as a self-declaration, formally called the manufacturer's declaration of conformity in EU law. It is not third-party certification.
A common trap is that some companies offer "EU packaging conformity certification" and present a certificate bearing the logo of an organization, claiming that applying it is sufficient for export to the EU. This is incorrect. EU customers require the Declaration of Conformity and the supporting technical file. They will not substitute an undocumented third-party certificate, nor will they release themselves from their own responsibilities because it exists. If a printer signs the declaration for the customer, it takes on the customer's responsibility instead.
US: many categories require third-party testing, not third-party certification. The US approach to food-contact materials differs from both of the others. The regulations are set out in 21 CFR, which lists permitted substances and conditions of use for specific materials. Products generally do not need a certificate proving that they "comply with FDA." They need a test report issued by a qualified laboratory, such as one recognized by FDA or operating in accordance with relevant quality-system requirements. Testing may cover migration and other parameters. The report must include a sample description, test methods, results, and information about the laboratory's qualifications.
The keywords for the US route are therefore "test report," not "certification." The customer uses the report together with product information to prepare a declaration of conformity or to submit it to the customer's own import compliance adviser.
The three pathways can be summarized as follows:
China — the enterprise makes a self-declaration and retains documentation, with random regulatory inspections.
EU — the manufacturer signs its own Declaration of Conformity. Technical evidence may come from a third party, but the declaration cannot be outsourced.
US — a test report from a third-party laboratory is required depending on the product category. There is generally no separate "certificate."
The customer asked: "The EU wants a declaration, the US wants a report, and China wants a documentation package. How many sets do I actually need to prepare?"
We replied: "Most of the content in the three sets can be reused. One of them must be signed by you."
The Second Boundary: Who Signs, What It Covers, and Whose Use It Serves
Once the three systems are understood, the next question is: can any of these documents replace another?
No. Using one in the wrong place is more dangerous than having none at all.
Using a test report as a declaration. This is the most common error. A customer receives an SGS migration report, says "this is our Declaration of Conformity," and places it in the file for platform review. The problem is that a test report covers only the tests listed in it and applies only to the samples described in it. A declaration must cover the entire product, including materials, inks, coatings, adhesives, the production process, and intended use conditions. The report's statement that it applies only to the submitted samples is legally effective.
Using a declaration as a test report. The reverse mistake is also common. A customer says, "We already have a Declaration of Conformity, so we do not need testing." A declaration does not generate data; it cites data. A declaration without supporting data, or with cited data that do not correspond to the actual product, will be required to be supplemented during regulatory or platform reviews.
Using the printer's test report as the customer's product report. This is the most dangerous practice for the printer itself. Some printers proactively offer: "We can submit the samples, and the report can be issued in your name." This sounds helpful, but the printer enters the commissioning party information, sample description, and statement of intended use on the customer's behalf. The product described in the report may not be the version the customer actually mass-produces. The customer may change the ink, paper, or coating supplier while the old report remains in the file, leaving the customer unaware that it is no longer valid.
The customer said, "Your testing is faster, and we will pay the cost." We replied: "We can arrange testing, but the sample description and commissioning party information must be based on your actual mass-production formulation. Fees will follow the third-party laboratory's standard rates. Once the report is issued, it must identify the formulation version it covers. If you change the formulation, the report will no longer apply."
Once this boundary is clear, both parties are protected. The printer provides a testing service based on the formulation confirmed by the customer; it does not endorse the customer's product compliance.
The Third Boundary: The Printer's Actual Position in the Chain
The third boundary concerns division of responsibility and is the most important issue for printers to clarify: is the printer's position the same in all three markets?
No.
In China, the printer produces the technical documentation. Two of the most valuable elements in the customer's documentation package are the ink and coating conformity certificates and the production batch records, both of which naturally remain in the printer's possession. These are not favors; they are records the printer should already retain. Our factory keeps four categories of records for every order and delivers them with the goods. First, material traceability: the supplier, model, and batch number of each paper, ink, coating, and adhesive. Second, process parameters: printing color values, drying or curing conditions, lamination tension, and die-cutting parameters. Third, process inspections: retained first articles, color difference records, and batch color control records. Fourth, finished-product inspections: records of bond strength, rub resistance, wet rub resistance where applicable, and appearance assessments.
We do not begin doing this only when the customer asks. We already perform these activities, but previously did not organize them into a deliverable format.
In the EU, the printer is a supplier in the upstream evidence chain. What the customer receives from us is not a Declaration of Conformity but three layers of material: the ink supplier's conformity certificate tied to a specific BfR recommendation number or EU material-specific regulation, our own process parameters and batch records, and test reports based on the formulation confirmed by the customer. The customer uses these three layers to sign its own declaration.
One sentence appears on the first page of our work instructions: "We provide evidence; we do not issue declarations." This is not an attempt to avoid responsibility. On the contrary, it means fully accepting the printer's responsibilities, including printing quality, batch consistency, and complete process records, while avoiding the part that the printer should not handle: the final conclusion on product compliance.
In the US, the printer supplies the test samples. This route is the simplest: testing is performed using the formulation confirmed by the customer, samples are prepared as required, and the commissioning information in the report must be truthful and complete.
The first thing a printer should confirm when accepting an order can therefore be stated clearly:
Is the printer being asked to provide technical support, or to issue a legally effective declaration?
If it is the former, the order can be accepted normally. If it is the latter, the printer must explain during the quotation stage that it will not issue the final declaration and why. If the customer accepts, the work can continue. If the customer does not, the printer may still proceed, but the boundaries of responsibility must be recorded in a contract attachment rather than left as a verbal arrangement.
We were caught by such a situation once. A customer told us, "Issue a declaration in our name first, and we will provide the documents later." The documents were never provided, and the customer encountered no immediate problems, so we assumed the matter had passed. Six months later, the customer underwent an export inspection that traced the declaration back to us. Only then did we learn that the intended use conditions in the declaration had been inferred from experience rather than confirmed.
One Sentence for Customers
When these three boundaries are brought together, there is one message we most want to convey to customers: "First determine whether you need evidence or a conclusion, and then decide what we should do."
A great deal of rework does not occur because the work was done incorrectly, but because the right thing was done when it should not have been. For example, submitting a test report as a declaration, or signing on the customer's behalf. A printer may spend two weeks arranging testing and obtain a perfect report, while the customer's actual missing element is the statement that it accepts responsibility for the product's compliance.
For this reason, our quotations now include a section titled "Scope of Compliance Support." It identifies the materials we provide, the document we do not provide, and what the customer must confirm before we proceed. The section is short, but it places both parties' responsibilities on the table.
Customers often ask: "If you do not sign, does the compliance risk fall on us instead?"
We reply: "Yes, and it should, because deciding which food the packaging will contact, how long it will be used, and at what temperature is your decision, not ours. What we can do is ensure that the technical evidence required to support that decision can withstand scrutiny."

FAQ
What is the difference between an EU Declaration of Conformity and third-party certification? Can a certification body sign one on a company's behalf for a fee?
No. Under EU regulations, a Declaration of Conformity (DoC) is a self-declaration by the manufacturer or importer. The party bearing responsibility must sign it and accept responsibility for its contents. No EU certification body can sign the declaration on a company's behalf or assume its liability. Some organizations offer so-called EU packaging conformity certificates bearing their logos, but such documents cannot replace the Declaration of Conformity and will not be accepted by customers or platforms. The correct approach is for the company to sign the declaration itself; the technical evidence cited in it, such as material certificates and test reports, may come from qualified third-party laboratories. The printer's role in this chain is to provide evidence, not to sign the declaration.
Can a third-party test report be used directly as a Declaration of Conformity?
No, because they cover different scopes. A test report covers only the tests specified in the report and the samples described in it. The statement that the report applies only to the submitted samples is legally valid. A Declaration of Conformity must cover the entire product, including materials, inks, coatings, adhesives, the production process, and intended use conditions. The reverse is equally incorrect: a declaration cannot replace a test report because a declaration does not generate data; it cites data. A declaration without supporting data, or with data that do not correspond to the actual product, will be required to be supplemented during platform reviews or regulatory inspections.
Can a printer submit samples for testing and have the report issued in the customer's name?
Yes, a printer can arrange testing, but the commissioning party information, sample description, and intended use statement must be based on the actual mass-production formulation confirmed by the customer. Fees should follow the third-party laboratory's standard rates, and the customer must be told clearly which formulation version the report covers. The risk arises when the printer completes the intended use details without verification or uses samples from trial production after the customer has changed the formulation. The report then no longer corresponds to the mass-produced product, while the customer may assume that testing has already been completed and further testing is unnecessary. The prudent approach is to reassess the report's applicability after every formulation change.
For the same food-contact packaging sold to China, the EU, and the US, how much do the printer's requirements differ?
The technical foundation is shared. Material certificates, ink conformity certificates, process parameter records, and batch inspection records form the same underlying set of evidence. The differences lie in the final deliverables and who signs them. China requires the company's conformity statement and an inspectable technical documentation package, with an emphasis on complete records. The EU requires the manufacturer's own Declaration of Conformity backed by technical evidence; the declaration cannot be outsourced, although the evidence can come from third parties. The US requires a test report from a third-party laboratory for many categories, usually in a report rather than certificate format. The workload differences are not substantial. The printer's additional task is to organize existing process records into a deliverable format.
If a customer asks the printer to issue a stamped Declaration of Conformity, should the printer accept?
Two matters must be distinguished. A printer may properly issue a quality conformity statement for the printed products it produces, covering matters such as color, batch, and compliance with agreed production specifications. A declaration that the product complies with food-contact regulations is fundamentally different because the party deciding its use bears the responsibility for placing it on the market. The prudent approach is to state the scope of compliance support in writing during the quotation stage, specifying which technical materials will be provided, that the final declaration will not be issued, and what the customer must confirm first. If the customer insists that the printer issue the final declaration, the printer should either decline or define responsibility through a contract attachment rather than relying on verbal arrangements.
The printer already has many records, so why does the customer still need to engage a testing laboratory?
Printer records and third-party reports prove different things. Printer records demonstrate that the production process was controlled, including which material batches were used, the process parameters, and first-article and batch inspection results. A third-party report demonstrates the product's performance under a specific test item, formulation, and intended use condition. The two are complementary and cannot replace each other. The printer's value lies in maintaining complete, traceable batch records and supporting sample submission based on the formulation confirmed by the customer. This gives the customer's report a reliable foundation of process control rather than a one-time, potentially unrepresentative sample.
