UK-companies which are based in Northern Ireland

If your company is based in Northern Ireland REACH, CLP, the BPR, PIC and POPs regulations do apply to you. As a company located in Northern Ireland, you have access to several of ECHA’s IT tools needed to fulfil your obligations under the above-mentioned legislation.

However, in certain situations concerning poison centre notifications and biocidal products, IT systems provided by the UK authorities need to be used.

Transfers of chemicals from Great Britain to Northern Ireland are considered as imports into the EU, and the relevant obligations for importers under REACH, CLP, BPR, PIC and POPs apply.

Similarly, exports of chemicals from Northern Ireland to Great Britain are considered as exports from the EU, and the relevant obligations for exporters under PIC apply.

Prior Informed Consent - Waivers

If you are a NI-based company planning to export a chemical listed in Part 2 or 3 of Annex I to the PIC Regulation, the importing country where you intend to export needs to give their consent before you can export the chemical. If the importing country does not respond to your designated national authority’s request for explicit consent, you may propose a waiver to the explicit consent requirement.
