TL;DR: Regulatory compliance during the sampling and approval stage is where most OEM packaging projects stall — not in production — because documentation gaps surface only when a customs hold or retailer audit triggers a retroactive review.
For a related specification, compare Colour Management & Proofing — Regulatory & Compliance Guide before finalising the packaging brief.
TL;DR: In our experience, projects that arrive at approval without a complete regulatory file require an average of 3–4 additional sample iterations, adding 15–20 working days to the timeline.
The Compliance Parameter That Controls Approval Speed — Substance Restrictions, Not Print Quality #
Most brand partners come to us focused on colour accuracy and structural integrity during sample review. Both matter. But the approval stage that consistently causes delays is documentation of restricted substances in inks, coatings, adhesives, and substrates — not the visual or functional checks.
The regulatory frameworks governing this are market-specific and surprisingly non-overlapping:
- EU market: REACH Regulation (EC) No 1907/2006 restricts substances of very high concern (SVHCs) above 0.1% w/w. For food-contact packaging, EU Regulation 10/2011 on plastic materials applies, with a specific migration limit (SML) of 10 mg/kg for individual substances and an overall migration limit (OML) of 60 mg/kg. Printed packaging also falls under the Council of Europe Resolution AP(2005)2 on printing inks.
- US market: FDA 21 CFR Parts 170–189 governs food-contact substances. For indirect food contact (packaging where ink is on the outer surface), the threshold question is whether ink components can migrate through the substrate — this is tested per ASTM F1921 for heat seal strength as part of a broader migration risk assessment.
- China domestic/export: GB 9685-2016 sets the positive list for food-contact materials and articles, covering additives with permitted use levels. For export products we manufacture here and ship to the EU or US, we apply both GB 9685-2016 and the destination-market standard — whichever is more restrictive governs our ink and varnish selection.
The compliance gap happens when a brand briefs us on market destination late, after ink and substrate have already been selected for the engineering sample. Changing ink systems after an approved colour standard is set costs 2–3 colour proofing cycles minimum.
What to Request from a Supplier — and What the Response Tells You #
Ask any OEM packaging supplier for their ink system Safety Data Sheets (SDS) and third-party migration test reports before the first physical sample is approved. The standard request looks like this: “Please provide SDS documentation for all inks, varnishes, and adhesives used in this job, plus a declaration of compliance (DoC) covering REACH SVHCs and [your target market food-contact regulation], with test data dated within the past 24 months.”
A qualified supplier can turn this around in 2–3 working days for standard ink systems. If the response takes more than 5 working days or returns only a generic supplier declaration without test reference numbers, that is a signal the compliance file is being assembled retroactively rather than maintained actively.
We maintain what we call our CMR-flag register — a live internal list of colorants and additives that are candidate SVHCs or CMR (carcinogenic, mutagenic, reprotoxic) Category 1A/1B substances. Any ink selection for a food-contact or children’s product brief gets cross-checked against this register as part of our standard artwork onboarding, before colour matching begins. This catches substitution issues at briefing stage, not sample stage.
Also request FSC Chain of Custody certification if your brand has sustainability commitments. FSC-STD-40-004 v3-0 governs CoC claims — your supplier’s certificate number should be verifiable on the FSC public database within 24 hours of request. Certificates are typically annual; check the expiry date on what you receive.
One more item that gets skipped: if your product ships to California, ask specifically about Proposition 65 compliance for inks and coatings. This sits outside FDA 21 CFR and requires a separate assessment for listed chemicals including lead, cadmium, and certain phthalates.
Cost Trade-Offs: Third-Party Testing vs Supplier Declaration #
This is a topic where practices genuinely differ across the industry, and there is no universal answer.
Some brands require independent third-party lab testing on every sample lot — Eurofins, SGS, Bureau Veritas. For food packaging with direct food contact, this is the correct approach and the cost delta is justified. Migration testing per EU 10/2011 through a third-party lab typically runs €400–700 per test condition, and a full food-contact compliance package for an EU launch can reach €1,500–2,500 depending on the number of food simulants tested.
For non-food packaging (cosmetics outer packaging, electronics boxes, apparel tags), a well-documented supplier DoC with SDS backing is accepted by most EU retailers without third-party confirmation — unless a REACH audit or retailer compliance questionnaire triggers a deeper review. Some brands in our network run annual third-party verification on their top 5 packaging SKUs and accept DoC for the rest. Others retest after any ink or substrate formulation change. Our recommendation for brands new to Chinese OEM sourcing: third-party test the first production run, then establish a testing cadence based on your retailer requirements and product risk category.
The counterargument for full third-party testing on every sample: it adds 10–15 working days and €500+ per sample cycle, and for paper-based, non-food packaging using standard offset inks, the migration risk is near zero. Over-testing here redirects budget from where the actual risk sits.
Technical Deep-Dive: Market Comparison for Regulatory Documentation Requirements #
The documentation set required for full compliance varies significantly by destination market. This creates real complexity for brands selling across multiple regions from a single SKU, since documentation is not always interchangeable.
| Requirement | EU Market | US Market | China (Export) |
|---|---|---|---|
| Primary framework | REACH EC 1907/2006 + EU 10/2011 (food contact) | FDA 21 CFR 170–189 + Prop 65 (California) | GB 9685-2016 + REACH/FDA for export |
| Substance restriction list | SVHC candidate list (240+ substances, updated biannually) | FDA positive list + Prop 65 list (~900 chemicals) | GB 9685-2016 positive list (additive-based) |
| Migration testing standard | EN 1186 series (aqueous/fatty/dry food simulants) | ASTM F1980 (accelerated aging) + FDA guidance | GB/T 5009 series for domestic; EN 1186 for EU-bound |
| DoC format required | Yes — supplier DoC per EU 10/2011 Article 15 | No mandatory format; 21 CFR 182/186 GRAS basis | GB 9685-2016 conformity declaration |
| Third-party lab required | Not mandatory but strongly expected by retailers | Required for food contact in most retail programs | Required for CFDA registration (food/pharmaceutical) |
| Update frequency | SVHC list updated Jan/July each year | Periodic FDA guidance updates; Prop 65 annually | GB 9685 under revision; check quarterly |
The practical issue for multi-market SKUs: an EN 1186 migration test using EU food simulants does not automatically satisfy FDA guidance, because the simulants and test conditions differ. Brands targeting both EU and US from the same packaging line need separate test protocols — or a lab that runs both simultaneously, which reduces combined cost by roughly 25–30% versus sequential testing.
One open question we’re tracking: the EU Packaging and Packaging Waste Regulation (PPWR), still in legislative finalization as of mid-2025, is expected to introduce mandatory recycled content thresholds and new substance restrictions for packaging placed on the EU market. How migration testing requirements will interact with recycled fiber content (which carries higher contaminant variability) is not yet settled. Our current position is to flag recycled-content substrates for food-contact jobs as requiring case-by-case migration risk review until PPWR implementation guidance is published.
Specification Notes for Brand Partners #
When you brief us on a packaging project requiring regulatory compliance documentation, the three pieces of information that let us quote and sample accurately from day one are: destination market(s), food-contact status (direct, indirect, or none), and whether any retailer or retail program compliance requirements apply (Walmart RS-01, Amazon packaging policy, Boots UK cosmetics standards, etc.).
The most common brief gap we see is destination market ambiguity — “global” or “TBD” is not a workable instruction for ink and substrate selection. If you are genuinely targeting multiple markets, tell us the top two. We will spec to the more restrictive standard and document accordingly.
Our standard sampling timeline for compliance-documented samples runs 18–22 working days from brief lock for rigid and folding carton formats. That timeline assumes ink system clearance is completed in the first 3 working days. If a new ink system needs to be introduced — for a specific Pantone match not achievable in our qualified CMR-checked palette — add 5–7 working days for formulation review and SDS update. Third-party migration testing, if required before sample sign-off, adds a further 10–15 working days and should be scoped into your project timeline from the start.
What is an SVHC and does it affect my packaging automatically?
An SVHC (Substance of Very High Concern) under REACH is a chemical identified for its carcinogenic, persistent, bioaccumulative, or endocrine-disrupting properties. Presence above 0.1% w/w in any article — including packaging — triggers a disclosure obligation to customers and, if placed on the EU market, to ECHA. It does not automatically prohibit use, but most major retailers treat SVHC presence as grounds for rejection. The current SVHC candidate list has over 240 entries and is updated twice yearly.
Does FDA 21 CFR apply to the outer printed surface of food packaging?
It depends on whether migration through the substrate is plausible. FDA guidance on indirect food contact recognizes that inks on the outer (non-contact) surface can migrate through paperboard to the food side. The relevant assessment is whether the ink components appear on the FDA positive list or qualify under the functional barrier provision. For coated boards below 350 gsm, we treat the outer surface as an indirect contact surface and specify low-migration inks regardless of where the ink sits.
Can one Declaration of Conformity cover both EU and US market requirements?
No. EU 10/2011 and FDA 21 CFR have different scopes, different positive lists, and different test method references. A DoC written to EU 10/2011 Article 15 format will not satisfy a US retailer’s compliance questionnaire that references 21 CFR. We issue separate DoCs for each destination market and flag this at brief stage so documentation costs are scoped correctly.
Our product isn’t food. Do we still need REACH documentation?
Yes, for EU market. REACH Article 33 disclosure obligations apply to all articles placed on the EU market, regardless of whether they are food-contact. If your packaging contains an SVHC above 0.1% w/w, you are legally required to inform customers. For non-food packaging using standard offset inks on certified substrates, SVHC presence is typically absent — but a supplier DoC confirming this is the document that closes the gap in a retailer audit.
What happens if our ink system changes mid-production run?
Any change to ink formulation, supplier, or substrate that affects the compliance basis for an approved sample requires what we log internally as a Compliance Change Notification (CCN) before production resumes. This is not optional for food-contact or children’s product packaging. The CCN triggers a re-check against our CMR-flag register and, depending on the change, may require updated SDS documentation or a new third-party migration test. Changes made without a CCN void the existing DoC.
