Introduction
A REACH declaration is useful only when it identifies the product, materials, components, Candidate List version and responsible party. For EU-bound consumer products, a generic “REACH compliant” PDF does not tell a buyer whether the exact article was evaluated, whether the supplier understands its information duties, or whether a later material change will be reported. Use a component map and a change-controlled evidence request before production.
Start With the Correct Question
REACH duties depend on the supply-chain role and whether the item is a substance, mixture or article. This guide is a sourcing workflow, not legal advice. The European Chemicals Agency’s communication guidance says suppliers of articles containing a Candidate List substance above 0.1% weight by weight must provide enough information for safe use; consumers may request information, which must be provided free of charge within 45 days.
The buyer should therefore ask: what is the article and its components; which materials and chemicals are relevant; what evidence supports the answer; which Candidate List version was considered; and who must communicate or report information in the destination supply chain? Do not assume one answer applies to every market or finished product.
Map the Product Before Requesting Documents
Break an SKU into practical components: main plastic body, metal hardware, cable, coating, adhesive, ink, textile, foam, battery, packaging and accessory. A compact product can contain many article-level decisions. For travel accessories, textiles, zippers, coatings and printed labels may each need supplier information. For desk devices, cables, housings, coatings and electronic assemblies may require a different evidence path.
Create a bill-of-materials review table with component, material family, supplier, country, revision, evidence received, open question and change status. It is not a laboratory report; it is the index that lets the buyer discover whether a declaration really covers the shipped configuration.
What to Ask a Supplier For
Ask for a declaration tied to the exact manufacturer, model, SKU revision and date, plus available material declarations, test reports, safety data where relevant and subcontractor information. Record the Candidate List date/version stated by the supplier. Ask the supplier to disclose uncertainties rather than converting “not tested” into “free from.”
Check document identity: issuer, applicant, sample description, model, material, methods, dates and conclusion. If a report says “plastic sample,” compare the pictured or described polymer with the actual part. If it covers an earlier color, coating or supplier, treat it as background evidence rather than automatic approval.
0.1% Is Not a Blanket Product Shortcut
ECHA explains that the 0.1% threshold applies to each article supplied, including articles in complex objects. That distinction matters for an assembled product with separate cable, enclosure, fastener or accessory articles. Qualified compliance advisers should determine applicability; a procurement team’s role is to preserve an accurate component map and obtain truthful supplier inputs.
The ECHA SCIP supplier guidance also describes information duties for articles placed on the EU market containing Candidate List substances above the threshold. Do not treat a SCIP submission, a supplier declaration and a product test report as interchangeable documents.

Make Change Notification Contractual
Material substitution is often commercial: a factory changes a zipper, pigment, adhesive, coating, cable, ink or package because of lead time or cost. It can also invalidate the evidence pack. Require advance written notice before any change to an approved bill of materials, subcontractor, process, factory or formula. The notice should show the original and proposed component, affected SKUs and lots, reason, document impact and requested approval.
Retain an approved sample with revision labels. During pre-production and shipment inspection, check visually identifiable material and labeling points against it. Inspection cannot identify an SVHC or prove chemical content, but it can expose an obvious changed component and keep the product file linked to real production.
Choose Evidence Proportionately
Not every component needs the same response. Prioritize items with direct skin contact, soft PVC or elastomers, coated surfaces, inks, adhesives, electrical cables, metal plating, textiles, foam and novelty finishes. Where a material is unknown, request technical clarification before assuming its composition. Where the commercial consequence of an error is high, seek appropriate independent professional or laboratory support.
Avoid claims such as “100% chemical-free” or “globally compliant.” They are hard to support and can create misleading marketing. State the actual scope: a supplier declaration references a named product and component list as of a stated date; it does not guarantee future materials without continued change control.
Records and Buyer-Facing Communication
Keep the RFQ, component map, supplier declarations, reports, change notices, approved sample images, artwork, shipment evidence and final product identifiers in a versioned folder. Confirm who owns consumer information requests and who has the source files needed to answer them. Update the file when the Candidate List, the product or the supply chain changes.
Frequently Asked Questions
Is a generic REACH certificate enough?
No. It may be background evidence, but buyers need model- and component-specific scope plus change control.
Does 0.1% apply only to the whole finished product?
ECHA explains that the threshold applies to each article supplied, including articles within complex objects.
Does a visual inspection prove chemical compliance?
No. It can identify an apparent substitution but cannot establish chemical composition.
When should the declaration be updated?
Update it after a Candidate List change or a product, material, supplier, factory or process change that affects the assessed article.
Can a buyer rely on a factory’s old test report?
Only after confirming it matches the exact product, material, method and current configuration; seek specialist advice where needed.
A Repeatable Component-Review Method
Begin with the finished product and work inward. Photograph or diagram the components, record their function and identify which supplier provides each one. A factory may assemble an item while purchasing cable, pigments, packaging, hardware or textiles from separate sources. The point is not to make every supplier produce the same document; it is to know which evidence relates to which component and where an unanswered question remains.
Use material families to organize the request. Plastics may require resin and color-masterbatch information; textiles may require fiber, coating, printing and trim information; metal parts may require plating or surface-treatment information. Adhesives and inks often appear only on packaging or assembly notes, yet a change can alter the product configuration. A document index with model revision and evidence status is more reliable than a shared folder called “REACH.”
When a supplier cannot support a claim, record that limitation and decide whether to change the material, obtain further information or seek independent assessment. Do not delete uncertainty from a declaration. Buyers commonly need evidence for commercial, retailer or legal review; transparent scope is more useful than a broad statement that nobody can trace.
Sampling, Testing and Supplier Assurances
Testing can answer a defined question about a sample and method. It does not automatically characterize every future lot or every component not included in the sample. Read the sample description, preparation, detection limits, method and result with the relevant specialist. If the result is being used for a retailer submission, check the retailer’s named requirements rather than assuming any report format is accepted.
Supplier assurances remain important because testing alone cannot economically cover every hidden material. Tie the assurance to the bill of materials, require notification of changes and retain the approved sample. During shipment inspection, look for visible differences such as a new coating gloss, cable, color, accessory or package. Escalate unusual differences before loading so the buyer can decide whether the evidence remains applicable.
Protecting the Reorder
The first order often gets close attention, while a later reorder is assumed unchanged. Reorders need a short reconfirmation: same product revision, same factory, same material sources or approved changes, same destination, and current Candidate List review. If any answer differs, reopen the relevant evidence items. This takes less time than rebuilding a product file after a retailer or consumer inquiry.
Store evidence in a way a future teammate can understand. Include the purpose of every document, the source, version, date, linked component and approval decision. It supports both practical sourcing and honest customer communication without overstating what factory evidence proves.
Use a Tiered Supplier Data Request
Begin with information the supplier should already control: current bill of materials, component and sub-supplier list, material descriptions, color or coating variants, existing declarations, relevant safety data sheets and change history. Ask for document scope and limitations in the supplier’s own words. This first tier often reveals whether an apparently complete declaration covers the finished SKU.
The second tier resolves higher-risk gaps. Request resin grade or polymer family, plating system, coating or adhesive identity, cable construction, textile treatment, ink system or other component-specific detail identified by the reviewer. Do not collect confidential formulas indiscriminately. A sub-supplier can sometimes give a controlled declaration directly to the buyer’s laboratory or compliance adviser when commercial sensitivity is legitimate.
The third tier is targeted testing or specialist assessment. Define the substance, component, sample, method and decision the work is intended to support. A laboratory should not receive a carton of mixed parts with the instruction “test for REACH.” Maintain an open-items list so a partial report cannot be mistaken for a complete product review.
Manage Complex Objects and Replaceable Parts
An assembled consumer product may contain articles sourced from several tiers. Map detachable accessories, cables, straps, fasteners and replaceable parts as well as the main housing. If a replacement part is supplied separately, it may need its own product identity and communication path. Ask a qualified adviser how article-level duties apply to the actual supply chain.
For a multi-material assembly, maintain an exploded-view photograph or diagram. Give each relevant part a simple component code that also appears in the supplier evidence index. This helps a future buyer recognize that “C03 black cable” in a declaration is the same item packed with SKU A and sold separately under SKU B.
Packaging should be included when it is part of the product or separately subject to a customer chemical policy, but keep its status clear. Do not merge product and packaging samples without understanding how the test result will be interpreted.
Check Report Applicability Line by Line
Read the report’s cover page, applicant, manufacturer, sample description, photograph, material, color, preparation method, test method, reporting limits, date and conclusion. Compare each item with the current bill of materials. A report can be authentic yet not applicable because the supplier changed the pigment, plating thickness, coating supplier or manufacturing location.
Create an applicability note rather than editing the report. State which current components it supports, what assumption was made, who reviewed it and when review is required again. If the report contains several composite samples, record which components were combined and whether a detected result can be attributed. Ask the specialist whether retesting individual parts is needed.
Beware of broad conclusions added by intermediaries. The laboratory result is tied to the received sample and method. A trading company’s summary may be useful, but it should not obscure the original report or transform “not detected above reporting limit” into “contains zero SVHC.”
Prepare for Customer Information and SCIP Inputs
Before launch, assign the person who will receive and coordinate article-information requests. Prepare a model record with supplier identity, article or component description, Candidate List version, safe-use information received and destination supply-chain contacts. The legal response and timing should be confirmed by the responsible EU adviser, but the source facts should not need to be reconstructed after a request arrives.
Where SCIP duties apply, separate the data preparation, submission responsibility and proof of submission from the supplier declaration. The ECHA Candidate List page should be monitored for updates relevant to the review. A database notification does not automatically update a finished-product file; create a scheduled impact check against active SKUs and materials.
For discontinued products, retain the evidence according to the responsible party’s recordkeeping policy. Reorders using old packaging still need a current material and Candidate List check.
Escalate Uncertainty With Commercial Options
When evidence is incomplete, give the buyer choices rather than a false pass or fail. Options may include obtaining a more specific declaration, asking the sub-supplier, changing to a better-documented material, commissioning targeted analysis, limiting a product variation or delaying artwork until the adviser responds. State cost, lead-time and residual uncertainty for each option.
Procurement can reduce risk by choosing stable materials and requiring approval of alternate sources. It cannot make a legal conclusion simply because launch timing is tight. A documented decision, with facts and limitations, is more trustworthy than a broad promise that later becomes impossible to defend.
Make the RFQ Comparable Across Suppliers
When several factories quote the same product, give each the same component disclosure template and evidence questions. Ask whether pricing assumes the specified material, whether alternate sources are planned, which documents are already available and which testing or declarations are excluded. A low quotation based on an undefined “standard plastic” is not equivalent to a quotation tied to a named, controlled material.
Score completeness separately from commercial price. Record unanswered questions and the cost or lead time to close them. If a supplier proposes a better-documented alternative, compare function, appearance, tooling, chemical-review needs and reorder availability before approval.
Attach the final component map and change-notification clause to the purchase order rather than leaving them in pre-sale email. The goal is not to make the factory warrant every legal conclusion. It is to preserve truthful product inputs so the responsible business can meet its own duties and respond when the Candidate List or product changes.
