EU REACH & CLP IMPORT CHECKLIST
Before importing a chemical mixture into the EU, companies should be able to connect its composition, substance-level REACH registration coverage, CLP classification and market-specific documentation to the actual supply chain. A REACH registration number provided by the supplier, a safety data sheet or a UFI can support that assessment, but each answers a different compliance question.
For importers of coatings, adhesives, cleaning products and other formulations, the practical challenge is establishing whether those records cover this product, this importer, these quantities and the intended markets.
Customs clearance does not resolve that question. Article 27 of Regulation (EU) 2019/1020 expressly states that release for free circulation does not establish conformity with EU law.
The checklist below provides a way to organise an internal pre-import review. It is not a prescribed EU customs document pack: the applicable obligations and any authority requests depend on the goods, company roles and circumstances.
Quick Navigation
What should an EU chemical importer verify?
Start with a product record that links the commercial name and formulation version to the responsible companies and supporting evidence.
| Evidence area | Records to obtain or reference | Question to resolve |
|---|---|---|
| Product identity | Product code, formulation version, substance identities and composition information | Do the records describe the mixture being imported? |
| Legal roles | Supplier and importer details; Only Representative arrangements, where relevant | Which legal entity fulfils each applicable obligation? |
| Substance tonnage | Annual import forecast and actual volumes across relevant products | What quantity of each substance is attributable to the importer? |
| REACH coverage | Registration information, documented OR coverage or an applicable exemption assessment | Does the basis relied upon cover the substance and supply chain? |
| Restrictions and authorisation | Substance-and-use screening and supporting assessments | Is the intended supply or use permitted under the applicable conditions? |
| Classification and communication | Classification rationale, EU SDS, label artwork and packaging specifications | Are the hazard assessment and customer-facing information consistent? |
| Notifications | C&L notification assessment; PCN records and UFI, where applicable | Have the correct obligations been addressed for the relevant substances and mixture? |
| Shipment traceability | Invoice, packing list, product and batch references | Can the consignment be linked to the reviewed product records? |
Assign an owner to each unresolved item. Procurement can obtain supplier documents, but regulatory staff need to assess their scope before logistics teams rely on them.
1. Confirm the importer and the scope of any Only Representative arrangement
Identify the EU/EEA legal entity responsible for the import. Commercial descriptions such as "distributor" or "sales office" do not, by themselves, establish the company's regulatory role.
An eligible non-EU manufacturer or formulator may appoint an EU/EEA-based Only Representative (OR) to fulfil covered REACH importer obligations. The arrangement must be traceable to the represented company, relevant substances and covered imports. Importers covered by that appointment are treated as downstream users for the relevant REACH purposes.
An OR appointment under REACH does not automatically transfer the importer's CLP responsibilities. Establish separately who assesses classification, prepares labels and addresses applicable notifications. ECHA's information for non-EU companies explains this division of responsibilities.
Where the role or coverage is unclear, an EU REACH obligation and Only Representative assessment can help determine which registration route applies before the supply arrangement is finalised.
2. Calculate tonnage by substance, across imported products
REACH registration applies to substances, including substances contained in mixtures. Subject to applicable exemptions, the general registration threshold is one tonne or more per substance per importer per year.
The assessment therefore needs to aggregate the same substance across relevant imported mixtures and imports of that substance on its own. Reviewing each product independently can miss the threshold.
Consider this simplified example:
| Imports by the same legal entity in one year | Quantity of mixture | Substance A concentration by weight | Quantity of Substance A |
|---|---|---|---|
| Mixture X | 4 tonnes | 20% | 0.8 tonnes |
| Mixture Y | 3 tonnes | 10% | 0.3 tonnes |
| Total | 7 tonnes | — | 1.1 tonnes |
Neither product contributes one tonne of Substance A individually, but their combined contribution exceeds the threshold. Assuming no applicable exemption or OR coverage, the importer must fulfil the REACH registration obligation for Substance A based on its aggregated annual imports.
This calculation requires sufficient composition information. SDS Section 3 is not necessarily a complete formulation: REACH Annex II requires disclosure of specified ingredients, while suppliers may additionally list other substances. An omitted ingredient cannot therefore be assumed absent from the product.
Where confidentiality limits disclosure, agree a controlled information-sharing arrangement with the supplier and relevant compliance parties. The arrangement must still provide enough information to establish and fulfil the applicable duties.
For polymer-containing formulations, assess the polymer, its constituents and other additives separately. Polymers are generally exempt from REACH registration, but their monomer substances and other chemically bound substances may require registration under Article 6(3). This assessment includes the applicable 2% by weight and one-tonne-per-year conditions and whether an actor up the supply chain has already registered the relevant substance. Non-bound additives and residual substances should also be assessed as appropriate.
3. Verify that the registration covers the actual imports
Keep a record of how registration coverage was established. A useful review should connect:
The substance identity to the registration being relied upon.
The represented non-EU company and supply route to the imported product.
The importer to the OR's coverage records, where that route is used.
Actual and forecast imports to the relevant quantity records and registration tonnage band.
Intended uses and conditions of use to the relevant registration information and exposure scenarios, where applicable, identifying any alternative action needed where those uses are not supported.
ECHA states that ORs must maintain supply-chain records covering importers and tonnage for enforcement authorities. Written confirmation should therefore be specific enough to resolve the importer's coverage question.
If registration is considered unnecessary, record the reason and supporting facts. "Low volume," for example, needs a substance-level calculation; an exemption needs an assessment against its conditions.
Registration coverage also leaves separate questions to resolve. Screen the substances and intended uses against applicable REACH restrictions and authorisation requirements. These obligations can apply below the registration threshold, and a registration number does not establish that every proposed use is permitted.
For an existing registration that requires maintenance, see our separate analysis of REACH dossier updates and supply-chain alignment.
4. Reconcile classification, SDS, labels and packaging
The importer needs a defensible classification for the actual formulation. Depending on the hazard class and available information, mixture classification may use data on the mixture, information on its ingredients or, where the applicable conditions are met, bridging principles based on similar tested mixtures. Retain the basis for the decision, including the formulation and data versions assessed.
Review the resulting documents together:
Does the classification rationale address the current composition?
Does SDS Section 2 reflect the mixture classification?
Does the label carry the required product identification, supplier details and applicable hazard information?
Are the SDS and label prepared for the destination market's language requirements?
Does the packaging meet the requirements applicable to the product and its supply to professional users or consumers?
ECHA's labelling guidance addresses supplier identification, hazard communication and packaging requirements. Language requirements must also be checked for the relevant destination markets.
A mixture that is not classified as hazardous may nevertheless require supplemental label information under CLP Annex II, such as EUH208 or EUH210. "Not classified as hazardous" should therefore not be treated as confirmation that no CLP labelling requirements apply.
Where an SDS is required, review its safe-use information as well as its classification. Relevant information from substance exposure scenarios may need to be incorporated into the mixture's safety communication; simply collecting an upstream SDS does not complete that assessment.
Certain mixtures not classified as hazardous may nevertheless require an SDS on request under REACH Article 31(3).
For current imports, check which classification rules and transition provisions apply. Under the new CLP hazard-class provisions, the mixture application date is 1 May 2026, with transitional treatment until 1 May 2028 for qualifying mixtures already placed on the market before that date. A long-established product name alone does not demonstrate eligibility for the transition.
If these records disagree, resolve the classification basis before revising individual documents. REACH24H's EU CLP compliance services support mixture classification, label preparation and SDS updates.
5. Check C&L notification and PCN separately
Two different notification systems can be relevant to an imported mixture.
C&L Inventory notification concerns substances. Assess whether the imported constituents fall within the notification requirements, including hazardous substances present at concentrations that trigger classification of the mixture. Document whether a separate notification is required or whether the relevant obligation has already been fulfilled through the applicable registration or notification arrangements.
Poison centre notification concerns mixtures within its scope. Article 45 and Annex VIII generally cover mixtures placed on the market that are classified for health or physical hazards, subject to exclusions and exemptions. Mixtures classified only for environmental hazards fall outside that notification obligation.
Where PCN is required, check the submission records against the actual formulation, product names, intended uses and Member States concerned. Confirm that the UFI used on the product corresponds to the submitted mixture information.
Generating a UFI does not submit a poison centre notification. ECHA treats UFI generation and notification submission as separate steps; its handbook also explains that a UFI validity check cannot establish whether it has been notified. Retain the relevant submission records rather than relying on the code alone.
Where required, C&L notification is generally due within one month of first import, while PCN must be completed before placing the mixture on the market. Import for own use may also trigger these obligations. For mixtures used exclusively at industrial sites, the UFI may be provided in SDS Section 1.1 instead of on the label, subject to the applicable conditions under CLP Annex VIII.
6. Other applicable requirements
Depending on the product, also check the POPs Regulation, biocidal product and treated-article requirements, detergents legislation, VOC limits for specified coatings, and packaging obligations. These requirements apply according to composition, intended use and market conditions; REACH and CLP compliance alone does not establish compliance with all applicable legislation.
7. Connect the review to each shipment—and reopen it when facts change
Once the product assessment is complete, logistics teams should be able to identify which reviewed formulation, SDS and label version apply to the consignment.
Use a consistent product reference across the purchase order, invoice, packing list and internal compliance record. If commercial and regulatory names differ, maintain a clear cross-reference. Supporting test reports, where relevant, should identify the material or batch assessed and explain their applicability to the imported goods.
A practical internal control is to pause dispatch where a material question remains unresolved—for example, the importer is absent from the OR coverage confirmation, or the supplier cannot explain which formulation a submitted UFI represents.
Define review triggers as well. A change in supplier, composition, importer, annual volume, destination market or intended use should prompt an assessment of which records and obligations are affected. A change does not always require a new registration or notification, but it should not pass through purchasing or logistics without that assessment.
Resolve evidence gaps before the next shipment
REACH24H can support REACH obligation and registration-coverage assessments, alongside CLP classification and hazard-communication reviews.
For an initial discussion, prepare the product description, available composition information, annual import estimates, importer and supplier details, existing OR documentation, SDS and label artwork. These records help identify whether the next step concerns registration coverage, missing supplier information or inconsistent product documentation.
