For food, agricultural and certain health or plant products, China applies quality and quarantine oversight through ASQIQ - the quality arm of the State Administration for Market Regulation - together with Customs quarantine, historically known as CIQ. Exports of these goods typically require a health certificate, a phytosanitary certificate, or a Customs inspection before the container leaves China, and the destination country then imposes its own food-safety import licence on top. This is a far stricter regime than general merchandise, because edible and plant products are high-risk and the requirements are category-specific down to the individual commodity. If you plan to source food, supplements or agricultural goods, confirm the exact certificate chain and the destination licence before you order, and use an agent experienced in food export who can actually produce the documents. Get it wrong and you risk a container held at both ends.
Buyers who have imported homeware or electronics smoothly are often blindsided by their first food order. The commercial mechanics look similar - supplier, PI, deposit, container - but the regulatory layer is entirely different and it operates on both sides of the water at once.
The practical consequence is that documentation, not price, becomes the critical path. A container of biscuits with a missing health certificate is a container that does not move.

The oversight is split between market-regulation quality standards and border quarantine. In day-to-day practice your exporter deals with both through the Customs system, and the outputs are the certificates your buyer's border authority will demand.
| Document | What it certifies | Typical commodity |
|---|---|---|
| Health certificate | Fit for human consumption | Processed food, beverages |
| Phytosanitary certificate | Free of listed plant pests | Dried goods, seeds, herbs |
| Veterinary certificate | Animal-origin safety | Animal by-products |
| Customs inspection release | Quarantine cleared for export | Most edible categories |
Clearing China does not clear your own border. The United States requires FDA prior notice and facility registration for food; the EU operates its own import controls with border control posts for products of animal origin; and most markets require an importer licence for edible goods. Both chains must line up on the same shipment.

Requirements are commodity-specific.
Licence, labelling, shelf life.
Facility must be eligible to export.
In writing, in the contract.
It sits on the critical path.
Language, allergens, nutrition panel.

The trading company that quoted the goods was not a registered exporter for that commodity, so no phytosanitary certificate could be issued in its name. The container sat in Ningbo while the paperwork was reconstructed through the actual processing facility.
We are candid about this category: food and agricultural export is a specialist chain, and we scope the document path before we quote a product. That means confirming the factory is a registered exporter for the specific commodity, mapping which certificate each border will demand, and checking your destination licence and labelling rules while the order is still an idea. Where a category sits outside our direct experience we say so and bring in an exporter who lives in it, rather than learning on your container. General merchandise forgives improvisation - edible goods do not.
Discuss a food or agricultural sourcing projectDirect answer: PPWR (Regulation (EU) 2025/40) applies from 12 August 2026 and replaces the old Packaging Directive. It makes the EU importer responsible for verifying packaging conformity and holding an EU Declaration of Conformity for every packaging type. Importantly, the DoC must be issued by the EU importer (or manufacturer) — a Chinese factory cannot validly issue it; it must supply the underlying technical evidence instead.
PPWR is a Regulation, not a Directive — it applies directly and identically in all 27 member states, replacing Directive 94/62/EC. From 12 August 2026 every packaging type needs a technical file and an EU Declaration of Conformity, producible on request by market-surveillance authorities. It covers sales, grouped, transport and e-commerce packaging of all materials. PFAS limits now apply to food-contact packaging, and heavy metals (lead, cadmium, mercury, hexavalent chromium) are capped at 100 mg/kg.

A common and costly misconception is that the Chinese factory issues the EU DoC. Under PPWR the legal power to issue and file the DoC sits with the EU manufacturer or importer. The factory's job is to provide complete, truthful underlying technical evidence — the packaging BOM, material composition, recyclability data, and hazardous-substance declarations. Without that factory evidence, the importer's DoC is invalid and useless at the border.

A Zhejiang exporter shipped gift sets to Germany in a mix of cartons, foam and PVC blisters. When the German importer's PPWR file was audited in mid-2026, the factory had only a generic 'compliant' letter — no packaging BOM, no heavy-metal test, no recyclability grade. The importer could not issue a valid DoC and the shipment was flagged. RND SOURCING stepped in, had the factory produce a full packaging BOM with per-material weights and a third-party heavy-metals test, and the importer then issued a proper DoC. The lesson: the factory supplies proof; the importer issues the document.
Importers should treat PPWR as a per-SKU packaging portfolio exercise.
| Action | Owner | Deadline |
|---|---|---|
| Inventory all packaging types/SKUs | Importer | Before Aug 2026 |
| Request DoC + technical file from supplier | Importer | By 31 Jul 2026 |
| Verify PFAS / heavy-metal limits | Supplier + importer | Ongoing |
| Hold DoC per packaging type | EU importer | From 12 Aug 2026 |
| EPR register per member state | Producer/importer | Before first sale |
RND SOURCING builds the factory-evidence package before goods leave China. We collect the packaging BOM (every material, weight and use), heavy-metal and PFAS test reports, and recyclability data, then hand the EU importer a complete file so the DoC is valid on day one. We also flag EPR registration per selling country, because selling without it blocks market access.

US consumer-product compliance has two hurdles that catch importers repeatedly. The CPSC requires that general consumer products are free of banned hazards, and that children's products are tested by a CPSC-accepted laboratory and covered by a Children's Product Certificate. That means working with suppliers who use compliant materials and retaining the test records yourself. California Proposition 65 is separate: if your product contains a listed chemical above the safe-harbour level, you must display the prescribed warning label, and many importers apply the label preemptively to avoid opportunistic litigation. Your agent should request the relevant test reports and confirm material compliance before production begins. Non-compliance risks recalls, fines and lawsuits, and fixing a problem after import costs many times what a pre-production check would have cost.
CPSC is federal product safety enforcement. Prop 65 is a California right-to-know law enforced largely through private lawsuits. They overlap in practice but they fail in different ways: a CPSC problem tends to arrive as a recall or a port hold, while a Prop 65 problem arrives as a demand letter from a plaintiff's firm.

Anything primarily intended for children twelve and under is a children's product, and the bar is meaningfully higher. Third-party testing at a CPSC-accepted laboratory is mandatory, and you must issue a Children's Product Certificate that references those tests.
Age grading drives everything.
Lead, phthalates, small parts, ASTM F963.
Not any lab - the acceptance list matters.
Importer's responsibility.
Any material change resets it.
Prop 65 does not ban chemicals; it requires a clear warning when exposure exceeds the safe-harbour level. Because litigation is the enforcement mechanism and defence is expensive, many importers apply the label preemptively even when they believe they are under the threshold.
| Common trigger | Where it shows up | Practical response |
|---|---|---|
| Lead | Metal parts, PVC, coatings | Material test report |
| Phthalates | Soft plastics, cords, grips | Specify compliant plasticiser |
| BPA | Hard plastics, can linings | Request BPA-free confirmation |
| Cadmium | Pigments, jewellery, solder | Test the finished part |
Applying the warning label preemptively is a common commercial decision, not an admission.

Almost every CPSC and Prop 65 failure we have seen traces back to a material or component substitution nobody flagged. Compliance is a bill-of-materials problem long before it is a laboratory problem.
The factory quietly switched the soft grip material between the golden sample and mass production because the new supplier was cheaper. The replacement contained a restricted phthalate above the children's product limit.

We treat the bill of materials as a compliance document, not a costing sheet. Before production we get material declarations on paper, we confirm the lab is CPSC-accepted rather than merely accredited, and for child-directed goods we make sure the certificate is issued against the tests that actually apply. During production our inspectors watch for the quiet substitution that resets everything - it is the single most common cause of a US compliance failure and it never appears in an email. We would rather hold a run for three days than let a labelled carton become a recall.
Ask us to check your US compliance pathCE marking is a declaration by the manufacturer that a product meets EU health, safety and environmental requirements. It is required for most products sold in the European Economic Area - electronics, toys, machinery, personal protective equipment, medical devices and many general consumer goods. To apply it lawfully you must test against the correct harmonized EN standard, keep a Declaration of Conformity and a technical file, and in many cases appoint an EU-based authorized representative. Without valid CE, customs can seize the goods and marketplaces such as Amazon EU will block the listing. Note that CE is self-declared for many categories, which is not the same as optional - you still need real testing evidence behind the declaration. Your China supplier should provide the test report and support the DoC, but the legal responsibility sits with whoever places the product on the EU market. Verify that the standard cited actually matches your product before shipping.
The most common misunderstanding is that CE is something a lab awards you. For most categories it is not. CE is a statement you make, backed by evidence you must be able to produce on demand. A lab report supports the declaration; it does not replace it.
That distinction matters because it means the paperwork burden - and the liability - sits with the party placing the product on the EU market, which is usually you, not the factory in China.

CE applies where an EU directive or regulation says it does. If your product falls under one of these families, assume you need it and find the matching EN standard.
| Product family | Typical directive / regulation | Common EN standard |
|---|---|---|
| Electronics and appliances | LVD, EMC, RED | EN 62368, EN 55032 |
| Toys | Toy Safety Directive | EN 71-1, -2, -3 |
| Machinery | Machinery Regulation | EN ISO 12100 |
| PPE | PPE Regulation | EN 166, EN 149 |
| Medical devices | MDR | EN ISO 13485 context |
Customs and market-surveillance authorities can ask for your technical file. If you cannot produce it, the CE mark on the box is meaningless. Build the file once and keep it current.
Often more than one applies.
Accredited lab, product-specific.
Drawings, BOM, risk assessment, reports.
Named legal entity, dated, signed.
Mandatory for many categories.
Standard retention expectation.


The supplier's 'CE certificate' was a one-page document issued by an unaccredited consultancy, citing no EN standard and naming no model. It would not have survived thirty seconds of market surveillance.
We tell buyers early that CE is their declaration, not the factory's favour, because that reframing prevents most of the trouble we see. On our side we identify the applicable directives with you, push the supplier for testing against the right EN standard at an accredited lab, and collect the drawings, bill of materials and reports your technical file needs while the factory still has them to hand. When a category needs a notified body or an EU representative, we say so before production rather than after. It is unglamorous work, but it is the difference between a clean customs entry and a container in limbo.
Talk to us about your CE requirementsFake or simply irrelevant test reports are common enough that you should treat every certificate as unverified until it passes a checklist. A real report names the specific product model rather than only the company; it comes from an accredited lab such as SGS, Bureau Veritas, Intertek or TUV; it is dated within the last 12 months; it cites the exact standard your market requires, for example FCC Part 15, EN 71 or RoHS; and the applicant on the report matches the supplier you are buying from. The classic red flags are generic 'company passed' certificates, expired dates, and tests run on a different product. For a high-value order, contact the lab directly and confirm the report number - reputable labs will verify. Your agent or inspector can also match the physical report against the goods during pre-shipment inspection. Never accept a certificate as proof without these checks.
Most bad reports are not elaborate forgeries. They are real documents used for the wrong purpose - a report for a similar model, a three-year-old test against a retired standard, or a certificate belonging to the trading company's other client. The supplier is not always lying; they are often just recycling whatever paperwork closes the sale fastest.
That is why the fix is procedural rather than adversarial. Ask the same five questions every time and most problems surface in minutes.


For any order where a compliance failure would be expensive, spend the twenty minutes. Accredited labs maintain verification desks precisely because report fraud damages their brand too.

Before deposit, not after production.
Even a genuine report describes a sample that was submitted months ago. The unit sitting in the warehouse may differ in material, coating or component. A good pre-shipment inspection closes that gap by comparing the tested specification against what is actually in the cartons.

The supplier supplied an EN 71 report that looked immaculate. The model number, however, belonged to a different puzzle set from the same factory, and the tested item used a different lacquer.
Every report a supplier sends us goes through the same five checks before it reaches you, and we do it in Chinese with the lab when the document is ambiguous. For higher-value or child-safety categories we verify the report number with the issuing lab and keep the confirmation in your file. At pre-shipment inspection our inspector carries the tested specification and compares it against the goods in the carton, because a valid report on a changed product is still a failed shipment. We have turned down suppliers over paperwork that did not hold up - that is the point of having someone on the ground.
