What is REACH Registration 2018?

REACH Registration 2018 represents the final deadline for the registration of phase-in substances. By 1 June 2018, any substance that has been pre-registered must be registered if manufacture/import is to continue in quantities of 1 tonne per annum (tpa) or more.

Who does it apply to?

Any company that pre-registered substances in the 1-10 & 10-100 tpa tonnage bands. If they wish to continue supply at quantities of 1 tpa or more, then a full registration would be required.

Phase-in substances manufacturer or imported in quantities of 100 tpa or more, or those which are carcinogenic, mutagenic or toxic to reproduction (CMRs) and supplied at 1 tpa or more should have already been registered by previous deadlines, in either 2010 or 2013.

Why is it important?

Registration means you can stay on the market and that you will have better quality information on your substances. Gearing up for registration will help to avoid supply chain interruption through substances failing to be registered and substances becoming suddenly unavailable. This could be especially important for your customers who are Downstream Users (DUs). For example, , formulators of mixtures, producers of articles, etc.

What might you have to do?

Registration will means getting active within your SIEF, determining who the Lead Registrant will be and beginning data sharing negotiations. This process can take some time so we advise that you begin this process as soon as is practicable. For more information and advice on data sharing and negotiation, see the links below.

If you are a downstream user or distributer, you may wish to begin probing your supply chain, enquiring as to the registration status of substances key to your business.

If you anticipate that your manufacture/import will remain beneath 1 tpa per substance, and therefore you will not have a registration duty, you may wish to update your REACH-IT account and possibly indicate that you are ‘inactive’ in the SIEF.

Regardless of your role in the supply chain, it is advisable that you know and assess your portfolio, find out if you have any registration obligations and take action as soon as possible.

Impact of EU referendum result

Based on the timescale for negotiating the UK’s exit from the EU it is our understanding that those UK-based companies affected still have the legal obligation to register their substances by the 2018 deadline.

What should I do next?

As a starting point, use the links below to find out more information. However, remember that you aren’t obliged to register. Ceasing manufacture/import or finding an alternative supplier with a valid registration are possible options. Downstream users should not assume that substances will be registered higher up their supply chain. It may be worth contacting your suppliers to see if they (or their suppliers) intend to register.
