Rohs reach testing notes for Amazon sellers: part 5
Amazon compliance reviews are document reviews first and chemistry second: the seller who can show a complete, traceable evidence set for RoHS and REACH keeps the listing live, while the seller with scattered supplier papers faces suspension. Build one file per product family, keep every report linked to real purchase lots, and retest whenever materials or factories change.
Key takeawaysMarketplace compliance checks mirror EU market-surveillance duties, and technical regulations legitimately require demonstrable evidence [1]. · Keep one document set per product family: test report, supplier declaration, and purchase records that tie the tested lot to your inventory. · Test reports carry weight when the laboratory operates under an internationally recognised accreditation system [2]. · Any change of material, coating, component source, or factory restarts the evidence clock. · Answer compliance requests with a complete set at once; piecemeal replies extend the review.
Selling electronics or coated goods on Amazon Europe means answering to two audiences at once: the marketplace compliance team and the EU market-surveillance authorities behind it. When either one asks questions, the seller who can produce a tidy documentation set keeps selling, while the seller who must start testing from zero watches the listing go dark for weeks.
The technical rules themselves belong to the EU legal system, and marketplaces enforce them because the law increasingly holds online platforms responsible for the products sold through them. This allocation of responsibility follows the same logic as the global framework for technical regulations, which expects conformity evidence to be available where the product is sold. Technical barriers to trade are legitimate when they protect health and the environment, and the associated procedures assume that suppliers can demonstrate compliance on demand [1].
This fifth note in the Amazon series is about paperwork rather than chemistry. It explains which documents compliance reviewers expect, how to keep reports traceable to the goods actually shipped, and when a paper set expires. None of it requires a laboratory background, only disciplined filing and a habit of retesting when products change.
Why marketplaces ask for test evidence at all
Online marketplaces did not invent these document requests. EU rules place duties on the economic operator behind each product, and enforcement authorities can demand technical documentation showing that a product meets substance restrictions. Because platforms now share part of that responsibility, their compliance teams pass the same demand down to sellers, usually at moments of stress: a new listing in a sensitive category, a customer complaint, or a sweep after a safety alert.
The underlying principle is familiar from international trade practice. Technical regulations and the procedures that verify them are an accepted part of cross-border commerce, provided they serve legitimate goals such as protecting health and the environment. The WTO framework for technical barriers to trade sets out how such measures should work so that safety is protected without disguised protectionism [1]. For a seller, the practical consequence is simple: substance rules are not optional extras, and the ability to prove compliance is part of market access.
Understanding this background changes how sellers prepare. The question is never whether a report exists somewhere in a supplier's inbox, but whether the seller can lay hands on a coherent set that names the seller's own product. Build that set before it is requested, because requests always arrive with deadlines.
Assemble one evidence file per product family
Group products that share materials, coatings, and component sources into families, and keep one file per family. A typical file holds the laboratory report on a representative sample, the supplier's material declarations for the restricted substances, the bill of materials showing which parts were covered, and purchase records connecting the tested lot to the inventory you actually sell. When a reviewer opens the file, the story should read itself: these goods, these materials, this evidence.
Sellers who source finished goods in China often combine factory paperwork with testing arranged closer to the source. RoHS REACH testing in China RoHS REACH testing in China lets the evidence cover the production lot directly instead of relying on certificates that travelled through several trading layers. Whatever route you choose, keep the report in your company name where possible, because papers issued to an unrelated trading company invite follow-up questions about the chain of custody.
Name files so a stranger can navigate them: product family, report date, laboratory, and version. Scan everything, including the pages sellers usually skip, such as the sample description and the method references. A reviewer who finds the lot number on the report matching the lot number on your invoice stops worrying, and that is exactly the reaction you want.
| Document | What it proves | When to renew it |
|---|---|---|
| Laboratory test report | Representative samples met the restricted-substance limits at the time of testing | Material, coating, component, or factory change; new substance added to scope |
| Supplier material declaration | Each supplier states the substance content of its parts | Any supplier or sub-supplier change; annual reconfirmation |
| Bill of materials | Which parts and coatings the evidence actually covers | Every design or sourcing change |
| Purchase and lot records | The tested lot is the lot you sell, not a golden sample | Every new production lot |
| Accreditation reference | The laboratory result sits inside a recognised competence system [2] | Check the mark and scope on each new report |
- Inventory what was askedRead the request twice and list every item named: report, declaration, invoice, photographs, or statements. Reviewers score completeness, so answer the exact list before adding extras.
- Match papers to the listed productPull the matching family file and confirm the report names your product and materials. If the file covers a sibling variant with different coatings, say so honestly and test the right one.
- Attach the lot linkageAdd the purchase records that connect the tested lot to your current inventory. This linkage turns a laboratory paper into evidence about your goods.
- Explain the set brieflyWrite a short cover note: what each attachment is, which product version it covers, and what you changed since, if anything. Reviewers clear tidy files faster than puzzles.
- Record the outcomeLog the request, the response date, and any reviewer remarks. Repeat requests on the same product usually focus on whatever was weakest last time.
A test report is only as portable as its credibility, and credibility travels through accreditation. The international laboratory accreditation system exists so that a result produced in one economy can be trusted in another, with member bodies recognising each other's competent laboratories [2]. When you file a report, check for the accreditation mark and confirm the laboratory's scope covers the methods used. That single habit prevents the painful discovery that an otherwise perfect report answers the wrong question.

Frequently asked questions
Which documents should an Amazon seller keep for RoHS and REACH?
Keep the report that matches the exact product and material set you sell, plus the supplier declaration and the purchase records linking the tested lot to your inventory. When a compliance request arrives, you answer with one coherent set instead of hunting through inboxes. Replace any paper the moment the product, material, or supplier changes.
Why keep test evidence ready even when nobody has asked for it?
Because a ranking warning, a category review, or a customer safety complaint can attach to any single listing at any time. Listings that can produce a complete evidence set within days usually recover faster than listings whose seller must start testing from zero. Treat documentation as part of the listing, not as an afterthought.
How do I know whether an old supplier report is still usable?
Check three things: that the report identifies your product and its materials precisely, that the test methods and limits match current EU rules, and that the issuing laboratory works under an accredited quality system. A report on a similar-looking product from another supplier proves nothing about your goods. If any of the three fails, commission fresh testing on your own goods.
What if the factory sent incomplete or inconsistent paperwork?
Do not edit supplier papers. Ask the supplier for the missing pages or a corrected declaration in writing, and record the request. If the supplier cannot deliver, have your own samples tested and keep the new report under your company name. A clean chain of papers in your own name is worth more than a patched supplier file.
