REACH registration: tonnage, existing data and the right filing route

Start with the substance and the registration role

REACH registration concerns substances and the actual manufacturer or importer’s obligations in the EU/EEA. Identify the substance, its composition and activities before applying the general one-tonne-per-year threshold and any exemptions. Mixture and article duties need their own assessment. A registration exemption does not remove every other chemical obligation.

Importer and eligible Only Representative routes

An EEA importer can fulfil its registration obligations. An eligible non-EEA manufacturer, formulator or article producer can appoint an EEA-established Only Representative by mutual agreement to cover defined importer obligations. This is not a compulsory representative purchase for every foreign seller. A supplier that is only a distributor does not qualify for that appointment route. Identify the acting legal entity, covered supply chain and responsibilities in the agreement.

Understand the tonnage bands

The standard information requirements build across Annexes VII–X at the 1–10, 10–100, 100–1,000 and at-least-1,000 tonnes-per-year bands. These are information requirements, not an automatic shopping list of new studies. Substance hazards, applicable reduced requirements, endpoint-specific rules and justified adaptations affect the actual dossier.

Use inquiry and current data-sharing procedures

New registrants use inquiry to identify co-registrants and assess substance sameness, joint submission and data access. Pre-registration is not a current starting route. The formal historical SIEF framework should not be presented as a new compulsory forum; ongoing data sharing and joint-registration duties remain. Review any existing registration, agreement or Letter of Access before pricing new work.

Assess existing evidence before commissioning tests

Gather reliable, relevant existing studies and consider lawful adaptations and non-test methods. Vertebrate testing is a last resort. Where required, testing proposals follow the applicable process before new studies are undertaken. A higher tonnage band alone does not prove every study must be repeated from scratch.

Separate the cost components

A useful quotation distinguishes substance identification, dossier and data-gap work, access to shared data, any needed studies, agency fees and representation or maintenance. Existing data rights and the scope of products, uses and tonnage affect the cost. Unsourced fixed ranges and universal completion times do not establish the price for a particular substance.

Registration and other obligations

Registration is not a certificate of complete legal market compliance. Restrictions, authorisation, classification, safety data sheets and article-related duties may remain. Article 7(2) Candidate List notification has both concentration and annual-quantity conditions and relevant exemptions; it is separate from other communication or waste-framework obligations.

Prepare a scoped enquiry

Describe the EU/EEA market, substance and available CAS/EC identifiers, annual quantity, supply-chain role, intended uses and existing registration or data-access records. Review the existing REACH service and request a quotation for the actual work needed. Do not send account passwords or confidential records through an unapproved channel.
