REACH registration step by step
Where the tonnage band fits in the process.
Your REACH Only Representative for non-EU substance manufacturers
REACH scales the data a registrant must provide with the quantity it manufactures or imports each year. Knowing your tonnage band is the first step in estimating what a registration will involve.
| Tonnes per year | Standard information required | Chemical safety report |
|---|---|---|
| 1 - 10 | Annex VII (physicochemical, basic toxicological and ecotoxicological data) | Not required |
| 10 - 100 | Annexes VII and VIII | Required (Article 14) |
| 100 - 1,000 | Annexes VII, VIII and IX (including proposals for higher-tier tests) | Required |
| 1,000 and above | Annexes VII to X | Required |
Tonnage is counted per registrant and per calendar year, for the substance on its own and in mixtures. An Only Representative registers the total quantity covered by its appointment - the combined imports of the importers it represents for that non-EU manufacturer. If you sell the same substance through several EU customers, their quantities add up under your OR's registration.
Data does not always mean new testing. Registrants can use existing studies, read-across from similar substances, weight of evidence or (Q)SAR models where Annex XI allows it, and animal testing is a last resort. For tests in Annexes IX and X, registrants submit a testing proposal and wait for ECHA's decision before running the test.
When your annual quantity reaches a higher band, you must inform ECHA immediately of the additional information that band requires (Article 12(2)) and update the registration within 3 months. Where new Annex VII or VIII tests are needed, a testing laboratory must be contracted within 3 months and the update follows within 3 months of the final reports (Implementing Regulation (EU) 2020/1435). Planning ahead matters, because higher-tier studies can take many months.
The standard information in Annex VII. A chemical safety report is not required in this band.
From 10 tonnes per year per registrant (Article 14). It includes a chemical safety assessment and, for hazardous substances, exposure scenarios.
The OR registers the total quantity imported by all EU importers it covers for that non-EU manufacturer, per calendar year.
No. Existing data, read-across, weight of evidence and other adaptations under Annex XI can be used, and animal testing is a last resort.
