Guide to chemical registration
To register a product with the OCNS:
- Complete a Harmonised Offshore Chemical Notification Format (HOCNF) registration form (Word, 233 KB), ensuring for each individual component all of the data requirements are met (see below).
- Submit the completed HOCNF form together with a safety data sheet by email or post to the OCNS team at Cefas. Please submit a safety data sheet in Dutch, in addition to English, if you require a Netherlands registration.
- The OCNS team will process the data from the HOCNF form, generate a template (certificate of use) and place your chemical product on the Definitive Ranked Lists of Registered Products. The period of certification is normally for three years.
- The template shows the product name, expiry date, and CHARM type. It will also show either a Hazard Quotient (HQ) or an OCNS letter grouping representing the environmental hazard of that particular product.
- The OCNS team will normally complete the assessment within an eight-week period from the date the completed HOCNF is received. Applications can be submitted up to six months before the expiry date of the product.
- Guidance on completing the HOCNF can be found on the OSPAR website.
Data requirements for OCNS registration
All chemical components except PLONORs (PDF, 176 KB) and those on the REACH (EC 1907/2006) Annex IV must have the following:
- full chemical name, molecular weight, CAS number and EINECS, ELINCS or REACH registration number*
- biodegradation and bioaccumulation (Log Pow) data
- full OCNS ecotoxicity data (algae, crustacean, fish and sediment-dweller*), expressed as either EC50 or LC50.
Field trial registration
A field trial registration lasts for a period of six months and information on the data requirements for both UK and Netherlands field trial registrations can be found in Appendix 5 of the Netherlands OCNS Protocol Part 1.
