REACH compliance check for EU importers and product suppliers
What a REACH compliance check should confirm
A REACH compliance check is a structured review of whether a substance, mixture or article can lawfully be placed on the EU market under the Registration, Evaluation, Authorisation and Restriction of Chemicals Regulation. For importers and product suppliers, the check should go beyond requesting a generic certificate. It should confirm the product category, the EU supply-chain role, the substances present, the applicable tonnage, any Substance of Very High Concern duties, Annex XVII restrictions, authorisation issues, Safety Data Sheet requirements and the evidence supporting the conclusion.
In practice, a reliable check combines supplier declarations, substance-level data, targeted testing where needed and ongoing monitoring of ECHA list changes. The term also needs one qualification: ECHA uses “compliance check” for its official review of registration dossiers under Article 41 of REACH. This article uses the trade and supply-chain meaning: the internal due diligence process carried out before importing, buying or selling goods for the EU market.
Start with product classification and supply-chain role
The first step is to define what is being placed on the market. REACH treats a substance, a mixture and an article differently. A solvent is usually a substance or mixture. A coated screw, a cable, a garment, a toy component or a piece of furniture is usually an article if its shape, surface or design determines its function more than its chemical composition. Complex products may contain many smaller articles, such as a zipper, button, printed circuit board, handle, gasket or coating layer.
The supply-chain role is just as important as the product type. An EU manufacturer or importer can have direct registration and notification duties. A distributor must pass compliant information down the supply chain and should not place non-compliant goods on the market. A non-EU exporter usually supports compliance by providing accurate composition, material and test information to the EU importer, or by arranging an only representative where REACH allows it and the commercial model supports it.
A useful first-page record for each item should state:
- whether the item is a substance, mixture, article or complex object;
- the EU legal entity placing it on the market;
- the supplier and production site covered by the evidence;
- annual EU volume estimates by substance where registration may be relevant;
- the intended use and foreseeable consumer or professional exposure;
- the version date of the Candidate List and restrictions checked.
Build substance-level evidence before screening lists
Many failed REACH reviews start with incomplete material data. A one-page supplier statement may be useful, but it is rarely enough for high-risk products or long-term purchasing. The buyer should request a bill of materials and, where possible, a bill of substances. At minimum, the file should identify materials, coatings, adhesives, inks, pigments, flame retardants, plasticisers, metal finishes and surface treatments that may carry compliance risk.
For substances and imported mixtures, the one tonne per year threshold is central. REACH registration duties generally arise when a company manufactures or imports a substance at one tonne or more per year. For an imported mixture, the key question is usually whether the individual substances in that mixture meet the threshold for the EU importer, not whether the mixture has a convenient commercial name. ECHA guidance also stresses that tonnage should be assessed per calendar year and aggregated across relevant routes.
For articles, a common mistake is treating REACH as a single finished-product test. The 0.1% weight-by-weight SVHC threshold is assessed at article level, including component articles in complex products. The Court of Justice of the European Union clarified this interpretation in Case C-106/14 on 10 September 2015, and ECHA guidance reflects that approach. A small plastic handle, rubber ring or coated fastener can therefore trigger communication duties even when the concentration in the whole assembled product appears low.
Check the four main regulatory gates
A practical REACH compliance check should move through four gates. The order may vary by product, but skipping one gate leaves a gap in the file.
Registration status
For substances manufactured in or imported into the EU at one tonne or more per year, the EU manufacturer or importer must determine whether registration is required and whether an existing registration covers the substance, tonnage band and use. If a non-EU supplier has appointed an only representative, the EU importer should obtain enough confirmation to show that its imported tonnage and uses are covered. “No data, no market” remains a practical way to describe the risk: if required registration data is missing, placing the substance on the market may be blocked.
SVHC communication and notification
The Candidate List changes over time. As of August 2026, ECHA’s Candidate List contains 253 entries after the 4 February 2026 addition of n-hexane and a Bisphenol AF substance group. Inclusion on the Candidate List can create immediate duties under REACH Articles 7, 31 and 33. Suppliers of articles containing a Candidate List substance above 0.1% w/w must provide safe-use information to professional recipients and, when consumers ask, respond within 45 days. Producers and importers may also need to notify ECHA if the substance is present above 0.1% w/w and the total amount in relevant articles exceeds one tonne per year, unless an exemption applies.
SCIP reporting for articles
SCIP is linked to the EU Waste Framework Directive, not only to REACH, but it uses the REACH Candidate List as the trigger. Since 5 January 2021, companies supplying articles on the EU market have had to submit SCIP information to ECHA when an article contains a Candidate List substance above 0.1% w/w. The data requirement can be more detailed than a customer declaration because it may require article identifiers, material categories, concentration ranges and safe-use information for complex objects.
Authorisation and restrictions
Annex XIV authorisation and Annex XVII restrictions should be checked separately. Authorisation focuses on listed substances of very high concern and specified uses after sunset dates. Restrictions can set concentration limits or bans for certain substances, mixtures or articles, including consumer products. In trade compliance, Annex XVII is often the more immediate shipment risk because customs or market surveillance authorities can test products for restricted substances above legal limits.
Use evidence that matches the actual product
A defensible REACH file should be specific to the item, supplier, material and date. The file does not need unnecessary paperwork, but it should show how the conclusion was reached. For higher-risk products, a good record includes supplier declarations, full or partial composition data, Safety Data Sheets for substances and mixtures, targeted laboratory reports, purchase specifications and change-control commitments. See also: Customs.
| Check area | Evidence to request | Common weakness |
|---|---|---|
| Substance or mixture registration | CAS or EC numbers, tonnage band confirmation, registration or only representative coverage, identified uses | Supplier gives a certificate but no substance identity or EU role |
| SVHC in articles | Article-level material declaration, Candidate List version date, component-level assessment | 0.1% calculated only against the total finished product |
| SCIP | Article identifiers, material category, SVHC name, concentration range and safe-use information | REACH Article 33 declaration is treated as if it automatically satisfies SCIP |
| Restrictions | Targeted testing for relevant substances and materials, with sample description and method | Testing covers one color, coating or batch while other variants differ |
| SDS and communication | Current 16-section SDS in the required EU language where applicable, exposure scenarios if relevant | Non-EU SDS format lacks REACH Annex II information |
Testing is not a substitute for supply-chain disclosure. A laboratory can check defined substances in defined samples, but it cannot prove that every Candidate List entry is absent from every material variation unless the test scope is designed for that purpose. Declarations and testing work best together: declarations map the risk, and testing verifies high-risk materials or commercially important claims.
Why importers should expect more data-driven enforcement
REACH enforcement is carried out by national authorities, while ECHA’s Enforcement Forum coordinates EU-wide projects. The direction is clear: imported substances, mixtures and articles are receiving targeted attention, often with customs cooperation and import declaration data.
On 10 December 2025, ECHA reported results from a Forum project in which inspectors in 29 EEA countries performed 2,603 targeted controls on imports for REACH registration, restriction and authorisation requirements. ECHA said one out of three substances in mixtures was missing a required REACH registration, and restricted hazardous substances were found above permitted limits in some imported consumer products. Earlier, a 2020 customs cooperation pilot checked nearly 1,400 products in 16 Member States and found 23% non-compliance with selected REACH and CLP obligations. These figures do not mean every sector has the same risk, but they show why importers should complete checks before shipment rather than after goods are detained, sampled or questioned.
ECHA also continues to use official dossier compliance checks. In its 2024 evaluation reporting, ECHA described 208 compliance check decisions and 92 testing proposal decisions requesting further information. For importers, the lesson is broader than dossier evaluation: authorities increasingly expect substance information to be current, traceable and consistent with the supplied product.
A practical workflow for import teams
Importers can make REACH reviews manageable by treating them as a repeatable workflow rather than a last-minute document request. The following sequence works for chemicals, mixtures and article supply chains:
- Map the transaction. Identify the EU importer, supplier, product family, customs description, intended use and sales countries.
- Classify the product. Decide whether each item is a substance, mixture, article or complex object.
- Collect material and substance data. Ask for CAS or EC numbers where relevant, article-level material information and details on coatings, additives and treatments.
- Screen current lists. Check Candidate List entries, Annex XIV authorisation substances and Annex XVII restrictions that apply to the materials and use.
- Decide legal duties. Determine registration, Article 33, Article 7(2), SCIP, SDS and restriction duties separately.
- Close data gaps. Use targeted testing, revised supplier declarations or substitution requests where evidence is weak.
- Record the conclusion. Keep a version-controlled file showing dates, sources, assumptions, test scope and the responsible reviewer.
- Monitor changes. Repeat screening when the Candidate List changes, the supplier changes formulation, annual tonnage increases or a product variant is added.
For broader trade and regulatory topics, import teams can also follow the Compliance section for related updates and practical explanations.
Frequently asked questions
Is a REACH certificate enough for import clearance?
Usually not by itself. A certificate can be part of the file, but it should identify the product, supplier, date, regulatory scope and evidence behind the statement. Authorities and customers may ask for article-level SVHC information, restriction test reports, SDS files or registration coverage depending on the product.
How often should a REACH compliance check be repeated?
Repeat the check when the Candidate List is updated, when the product design or material changes, when a supplier or production site changes, when EU volume approaches a registration threshold, or when an Annex XVII restriction changes. For stable products, many importers also set periodic reviews to prevent outdated declarations from remaining in purchasing files.
Does REACH apply to finished consumer products?
Yes, if they are placed on the EU market and fall within REACH scope. Finished products may be articles or complex objects. They can trigger SVHC communication, SCIP reporting and restrictions even when no registration duty applies to the finished article itself.
What is the difference between REACH and SCIP?
REACH sets chemical registration, communication, authorisation and restriction duties. SCIP is a database obligation under the Waste Framework Directive for articles containing Candidate List substances above 0.1% w/w. The trigger is related, but the information format and submission process are not identical.
Bottom line
A strong REACH compliance check is evidence-based, article-level where needed and current to the latest applicable lists. For importers, the highest-risk gaps are usually unclear EU responsibility, missing substance identities, outdated SVHC declarations, whole-product rather than article-level calculations, weak restriction testing and non-EU SDS formats that do not match REACH expectations. The practical goal is not to collect paperwork for its own sake, but to show that the product, substance data, legal duty and compliance conclusion all match before the goods enter the EU supply chain.
