TL;DR: Packaging compliance documentation fails at the market-entry stage not because brands lack certifications, but because they submit the wrong document format for the destination market’s regulatory pathway.
TL;DR: In our experience coordinating export documentation for over 40 brand partners annually, mismatched standard references — citing ASTM where EN is required, or GB/T where FDA 21 CFR is expected — account for roughly two-thirds of first-submission rejections we help clients resolve.
Where Compliance Documentation Actually Breaks Down #
The shipment clears Chinese customs without issue. It lands in Rotterdam, Los Angeles, or Sydney — and then sits in a warehouse while a compliance officer requests documentation that technically exists but was filed under the wrong regulatory framework.
This is the most common documentation failure we see: a brand has done the testing, commissioned the declarations, and assembled a compliance file. The paperwork is real. But the format, the referenced standard, and the issuing body all correspond to the wrong market. A Declaration of Conformity written to EU Regulation No 10/2011 for food-contact plastics is not interchangeable with an FDA 21 CFR §175–178 Letter of Guarantee — even if the underlying test data overlaps. Customs and market surveillance authorities in each jurisdiction are checking against their own regulatory index, and a mismatch triggers a hold or a full re-submission cycle.
The underlying reason this happens: brand teams brief us on product specifications, but they don’t always specify the end market with the same precision. “We need food-safe packaging” is not a compliance brief. We need to know the destination country, the distribution channel (retail shelf, e-commerce, foodservice), whether the packaging contacts food directly or is a secondary layer, and the intended shelf life at stated storage conditions. Each of those variables changes which standard applies and what documentation format the receiving authority will accept.
The Parameters That Determine Which Documentation Package You Need #
The documentation set is not a fixed list — it’s a function of four variables that interact: contact layer classification, market jurisdiction, packaging material type, and the specific regulatory pathway the product enters through.
Contact classification determines testing depth. Direct food-contact materials require full migration testing per EN 13130 series or FDA 21 CFR Part 176–178 depending on jurisdiction. Indirect contact or secondary packaging typically requires only a supplier declaration — but “indirect” must be confirmed in writing against the packaging geometry and fill process, not assumed. We log this determination in our CAF-02 Contact Assessment Form before any testing is commissioned.
Jurisdiction is where the table below matters most. EU, US, and China each maintain parallel but non-equivalent frameworks, and testing conducted to satisfy one does not automatically satisfy the others.
| Requirement Area | EU | US | China |
|---|---|---|---|
| Food-contact framework | Regulation (EC) No 1935/2004 + 10/2011 | FDA 21 CFR 175–178 | GB 9685-2016 |
| Migration testing standard | EN 1186 / EN 13130 | FDA guidance documents | GB/T 5009 series |
| Declaration format | Declaration of Compliance (DoC) | Letter of Guarantee (LoG) | Product hygiene certificate |
| Ink & coating restriction | EuPIA GMP + REACH Article 33 | Negative list approach (FDA) | GB 9685 positive list |
| Forest certification reference | EUDR (from Dec 2025), FSC | SFI / FSC (retailer-driven) | CFCC / FSC |
| Heavy metals (packaging) | EU Directive 94/62/EC, ≤100 ppm total | CONEG, ≤100 ppm total | GB/T 16716 series |
| Sustainability reporting | PPWR (packaging data filing from 2026) | No federal equivalent | Not yet mandated |
Material type changes the applicable standard at the test level. A flexo-printed kraft mailer and a heat-sealed PET/PE laminate pouch both need food-contact compliance — but the test protocol, the migration simulant, and the exposure time differ significantly. For polyolefin laminates, we specify overall migration testing at 10 days / 60°C using simulant D2 (vegetable oil) per EN 1186-1 to cover worst-case fatty food contact. For paper-based substrates, aqueous simulants at 40°C for 10 days are used per the same framework, but the extractables list changes.
Regulatory pathway — whether the product enters as a general trade item, under a retailer private-label program, or through a regulated channel like pharmacy or infant nutrition — controls the AQL level required at incoming inspection. Our standard is AQL 2.5 for visual defects on all food-contact packaging; for pharmaceutical and infant nutrition channels, we tighten to AQL 1.0 per ANSI/ASQ Z1.4.
The most commonly overlooked parameter is shelf life at stated storage conditions. A 12-month ambient shelf life and a 12-month refrigerated shelf life require different migration test temperatures and durations — and we’ve seen declaration packages approved at ambient conditions submitted for refrigerated-shelf products, which then fail retailer audits.
Decision Framework — Which Document Package Applies to Your Project #
If your product ships exclusively to the US market through retail channels, the documentation anchor is an FDA Letter of Guarantee from the material supplier, supported by your own internal compliance statement referencing the relevant 21 CFR part numbers. No EU Declaration of Conformity is required — but if you plan any EU distribution within 18 months, commission the EU testing now. Running parallel test programs after the fact costs roughly 60–90 days and duplicates lab fees.
If your product ships to the EU (including UK under the UK PLAS framework post-Brexit), your Declaration of Compliance must be structured per the EC No 1935/2004 traceability requirements, meaning it must be traceable through every material layer back to the monomer or additive level. An ink supplier’s REACH Article 33 SVHC declaration alone does not satisfy this. You need a full compositional declaration from each tier-1 material supplier, and we require that documentation before we release any production batch.
If your product ships to both the EU and China, expect two parallel documentation packages with no meaningful overlap in format. GB 9685-2016 uses a positive-list approach for additives that is stricter in some categories than EU 10/2011 — particularly for certain plasticizers and UV stabilizers. Our sourcing team maintains an approved supplier list (ASL) cross-referenced against both frameworks; materials that fail either list trigger our QC-07 material risk escalation procedure before they’re approved for production.
For FSC chain-of-custody: if your brand requires FSC-certified packaging for EUDR compliance or retailer sustainability programs, the certification must cover the paper mill, the converter (us), and the printer as separate CoC links. A single FSC label on finished packaging without a documented chain back to the certified forest is not compliant. Our FSC CoC certificate number is available on request and covers all paper-based substrates we run in-house.
One boundary condition: this framework applies to primary and secondary consumer packaging. For transit/tertiary packaging (corrugated shippers, pallet wrap), the documentation requirements are lighter — ISTA 2A or 3A performance testing rather than migration compliance, and heavy metals declarations per EU 94/62/EC are still required but migration testing is typically not.
Specification Notes for Brand Partners #
When you brief us on a new packaging project requiring compliance documentation, the most useful information you can give us upfront is: destination market(s), distribution channel, contact layer description (direct food contact, indirect, or non-contact), expected shelf life, and storage conditions. Without all five, we cannot correctly scope the documentation package or commissioning timeline.
The gap that causes the most sample iterations is ambiguity about contact classification. Brand teams sometimes describe packaging as “non-contact” because there’s a liner or tray between the food and the outer box — but if that liner is also supplied by us or specified in the brief, it falls within our compliance scope. Confirming the full packaging system geometry in the initial brief avoids a documentation revision cycle that typically adds 15–20 working days.
Our standard documentation package compilation timeline, once all material declarations are received from tier-1 suppliers, is 10–15 working days for single-market projects and 20–25 working days for dual-market (EU + US or EU + China) projects. Timeline extends if third-party migration testing is required — most accredited labs return results in 20–30 working days from sample submission. Plan for a total of 6–8 weeks from project brief to full compliance file for a new direct-contact food packaging format entering a regulated market.
What documentation do I need for food-contact packaging sold in both the EU and the US?
Two separate documentation sets — they don’t substitute for each other. For the EU, you need a Declaration of Compliance structured per EC No 1935/2004, supported by migration testing per EN 1186 and/or EN 13130 as applicable to your material type. For the US, you need FDA Letters of Guarantee from your material suppliers referencing the applicable 21 CFR part numbers. The underlying test data can sometimes be shared between markets, but the declaration format and referenced standards must match each jurisdiction’s requirements. If you’re launching in both markets simultaneously, brief us at least 10–12 weeks before your target production date to allow for parallel testing.
Does FSC certification cover EUDR compliance for wood-based packaging?
FSC chain-of-custody certification provides strong supporting evidence for EUDR due diligence, but it’s not a direct substitute. EUDR (EU Deforestation Regulation) requires documented evidence that the land used for timber sourcing was not subject to deforestation after December 31, 2020 — and while FSC-certified supply chains are designed to meet this, the EUDR filing requirement involves a geolocation data submission to the EU Information System that is separate from FSC record-keeping. Our FSC-certified paper substrates have supplier-level geolocation data available; it depends on the specific mill whether that data is formatted for direct EUDR submission.
Our product has a 24-month shelf life. Does that change the migration testing conditions?
Yes — and this is where projects sometimes get scoped incorrectly. Migration testing conditions are set based on the worst-case contact scenario, not just the migration period. For a 24-month ambient shelf life with a fatty food simulant (D2), the standard test under EN 1186 would use accelerated conditions (10 days at 60°C) representing long-term storage below 40°C. If your product is stored or transported at elevated temperatures — above 40°C for any portion of the supply chain — the test temperature needs to increase accordingly. Our dataset on accelerated vs. real-time correlation only covers ambient conditions up to 40°C; for cold-chain or high-temperature storage scenarios, we’d recommend confirming the test protocol directly with the accredited lab before commissioning.
