REACH regulation in Ireland and your company's legal duties
The REACH regulation applies directly in Ireland. Check your business duties for registration, safe use, restrictions and supply-chain information.
The EU REACH regulation is Regulation (EC) No 1907/2006. REACH stands for Registration, Evaluation, Authorisation and Restriction of Chemicals, and it is EU chemicals legislation that applies directly in Ireland. Your duties depend on your business role, the substances you handle, their quantities and uses, and the products you supply. The Health and Safety Authority (HSA) is Ireland's lead competent and enforcement authority. Its REACH overview is a practical starting point for Irish REACH guidance.
What the REACH regulation covers
REACH entered into force on 1 June 2007. It covers substances on their own and in mixtures, with relevant duties also applying to articles. REACH is a regulation, not a "REACH directive" and not a separate Irish registration scheme. See the HSA overview.
Exemptions need care. A registration exemption does not necessarily remove every other duty. Check which provisions apply before treating a substance or use as exempt. Article 2 of REACH sets out exclusions and exemptions.
REACH also differs from CLP. The CLP regulation concerns classification, labelling and packaging. The two laws complement each other. A product label and a REACH safety data sheet do different jobs.
What your company needs to do
Start with your role. Manufacturing or importing a substance, using a supplied mixture and selling an article can involve different duties. Don't assume every business must register a substance with ECHA. The HSA registration guidance explains the registration route.
Manufacturers and importers
A manufacturer or importer generally must register each substance manufactured or imported at one tonne or more per year. Exemptions can apply. ECHA receives the registrations. For imported mixtures, assess the constituent substances rather than registering the mixture as one entity. See Article 6 of REACH and the HSA registration guidance.
A qualifying non-EU manufacturer can appoint an EU-established Only Representative. Importers covered by that appointment are regarded as downstream users for REACH purposes. Check that the appointment covers your supply rather than relying on a general assurance from the supplier. The legal basis is Article 8.
Registration does not approve every use. But a registration number on its own does not prove safe use, authorisation or restriction compliance. The REACH legislation sets out these different obligations.
Downstream users and distributors
Formulators, refillers and professional or industrial end-users can be downstream users. They must implement safe-use measures and check their actual uses and conditions against exposure scenarios where supplied. The HSA downstream-user guidance explains how to assess that coverage.
An uncovered use needs action. Options include asking the supplier to cover it, changing the conditions or supplier, or completing a downstream-user assessment where applicable. Stopping or substituting the use may also be an option. An uncovered use does not automatically mean that the user must register the substance. Follow the HSA's guidance on uncovered uses.
Distributors do not become registrants solely because they sell chemicals. They do have supply-chain communication duties. Pass relevant safety information down the chain. Tell your supplier about new hazard information or risk-management advice that does not suit your use. See HSA supply-chain guidance.
Producers, importers and suppliers of articles
Article duties need their own check. Under Article 7(1), registration can apply to a substance intended for release under normal or reasonably foreseeable conditions. The substance must total over one tonne per producer or importer per year, subject to exemptions. This differs from Article 6's "one tonne or more" threshold. See the REACH text.
Not all article duties require an intended release. For Candidate List substances above 0.1% weight by weight, article suppliers must give recipients sufficient information for safe use. That includes at least the substance name. They must answer consumer requests within 45 days of the request. This Article 33 duty has no one-tonne trigger. See HSA supply-chain guidance and the REACH text.
Separate notification to ECHA under Article 7(2) applies to Candidate List substances, and it generally requires both a concentration above 0.1% weight by weight and a total over one tonne per producer or importer per year. Exemptions can apply. Don't confuse that notification threshold with the Article 33 communication duty. The legal thresholds are in the REACH text, and the HSA article-notification guidance explains the distinction.
Registration, authorisation and restrictions are separate checks
The REACH name describes several processes. Registration concerns submitting substance information. Evaluation is a separate process under the regulation. Neither term means that every possible use is approved. Three lists often cause confusion, and the HSA overview explains the wider framework. Check the Candidate List and authorisation separately from restrictions:
| List | What to check |
|---|---|
| Candidate List | Relevant information duties. Inclusion alone is not an automatic ban or immediate authorisation requirement. |
| Annex XIV, the Authorisation List | The substance's sunset date, exemptions and applicable authorisation arrangements. |
| Annex XVII, restrictions | The exact entry's scope, conditions, exemptions and dates. |
A restriction can limit or prohibit manufacture, placing on the market or use. Depending on the entry, it can cover substances in mixtures or articles. A registration does not override it. Read the relevant Annex XVII restriction against your actual product and use.
Safety information is part of REACH compliance
Safety data sheets support safe handling and communication. Other supply-chain information can also be required. Do not assume every product needs an SDS, or that receiving one completes all your REACH checks. A supplier declaration alone does not establish full compliance either. See the HSA information requirements.
Where Irish REACH guidance fits
The HSA is the lead authority, not the only Irish authority involved. Other authorities have specific remits under the revised Chemicals Act 2008. That Act provides the national enforcement framework. ECHA receives registrations, while the HSA provides Irish guidance and helpdesk support through its REACH pages.
For questions, contact the HSA chemicals helpdesk at chemicals@hsa.ie or 0818 289 389. Both contacts appear on the HSA overview. Before contacting it, set out your role, substance, quantity and intended use so the question is specific.
Irish guidance helps businesses interpret and implement duties. The binding requirements come from the EU regulation and applicable amendments. REACH remains in force and has been amended over time. The European Commission describes a broader revision as ongoing. Check current legislation and the transition dates relevant to your activity. Consolidated texts are documentation tools; authentic acts and amendments are published in the Official Journal.
A practical REACH compliance workflow
Use this as a review sequence, not a universal statutory checklist. It only orders the checks above and does not create a new legal test. Work through it with the HSA registration, downstream-user and restriction guidance pages:
- Identify your role for each supply route and the substances involved.
- Establish who holds registration responsibility and whether relevant coverage applies.
- Compare actual uses with safety information and exposure scenarios where supplied.
- Check Candidate List duties, authorisation requirements and applicable restrictions separately.
- Keep supporting information together and review it when supply, use or legal conditions change.
