Do non-EU manufacturers need an Only Representative under REACH?

Yes. Non-EU manufacturers cannot register directly. Appointing an EU-based Only Representative allows you to fulfill importer obligations centrally and your EU importers become downstream users.

Can we change our EU REACH Only Representative later?

Yes. Data and registrations can be transferred to a new OR. We plan the transition and handle authority notifications to avoid supply disruption.

Do I need a separate OR for UK REACH?

Possibly. EU REACH and UK REACH are separate frameworks. If you place substances on the Great Britain market, a UK-based OR and separate registrations may be required.

How much does a REACH Only Representative cost?

Costs depend on substances, tonnage band, data gaps, and consortia/testing needs. We provide a transparent quotation after scoping.

REACH Only Representative for Non-EU Manufacturers

Under Article 8 of EU REACH Regulation (EC) 1907/2006, non-EU manufacturers, formulators, and article producers cannot register chemicals directly with ECHA. To place chemical substances on the EU market, you must appoint an EU-based Only Representative (OR) who takes on your REACH registration and ongoing compliance duties.

Chementors has acted as Only Representative for non-EU companies since 2012. We are a Finnish EU legal entity, ORO and REACHReady member, with 150+ completed REACH registrations across chemicals, mixtures, and articles.

What an Only Representative does under Article 8

Article 8 of REACH (EC 1907/2006) defines the Only Representative as the only legal mechanism by which a non-EU manufacturer, formulator, or article producer can satisfy EU REACH registration obligations.

The OR registers your substances under its own name, on your behalf, and assumes all importer duties from the moment a written agreement is signed.

Your EU importers then become downstream users: relieved of registration obligations, free to buy from you without managing REACH themselves.

An Only Representative is:

A legal entity physically established in the EU/EEA
The holder of your REACH registration on your behalf
Your point of contact with ECHA for all REACH matters
An expert with the technical background and practical experience to fulfil OR duties

An Only Representative is not:

An import or export agent
A logistics or customs broker
A consultant alone — an OR must legally hold and execute all REACH duties of the importer, not just advise on them

Under Article 8, a qualified OR must:

Be a natural person or legal entity physically established in the EU
Possess the expertise and technical know-how to manage data, compile dossiers, and handle post-registration requirements
Be formally appointed through a written agreement with the non-EU manufacturer, formulator, or article producer
Fulfil all importer obligations under REACH, including the registration itself and the ongoing duties that follo

Who needs to appoint a REACH Only Representative?

If you are based outside the EU/EEA and your products contain chemical substances at one tonne per year per legal entity or above, REACH applies — and you cannot register those substances yourself. Three audiences must appoint an OR.

Substance manufacturers

Producers of a chemical substance — sold on its own or as part of a mixture — bound for EU customers. Without an OR, your EU importers must each register every substance independently, and most won’t absorb that cost. The practical effect: no OR, no EU market.

Mixture formulators

Formulators of paints, coatings, lubricants, adhesives, cosmetic raw materials, cleaning products, and similar finished mixtures. The OR registers each in-scope substance in your formulation, which clears the entire mixture for sale across the EU.

Article producers

Producers of articles — electronics, textiles, furniture, automotive accessories, toys — that contain a substance intended to be released under normal use, in quantities above one tonne per year per substance. REACH treats these the same as bulk chemicals. If you sell a leather sofa with a chromium-treated finish, the chromium has to be registered.

Three real situations we see at Chementors

A US lubricant formulator with five EU customers. None of the importers had registered the substances. Each refused to absorb the per-substance REACH costs. The formulator either appointed an OR or lost the EU market — there was no third option.
A Chinese cosmetics raw materials supplier whose EU distributor went bankrupt. Their substances had been registered through the distributor’s OR. With the distributor gone, the registration was effectively orphaned. They had a six-week window before the next shipment was blocked at customs.
An Indian pharmaceutical intermediates manufacturer transitioning between ORs. Their previous OR had failed two ECHA compliance checks and couldn’t explain why. They needed a new OR who could audit the existing dossier, fix the gaps, and take over without disrupting registrations. The transition process is different from a first-time appointment — see our guide on changing your Only Representative.

How Chementors handles your OR mandate

When you appoint Chementors, you appoint a team, not a postal address. The OR mandate covers everything from substance identification through ongoing compliance after the dossier is submitted.

Representation and communication

Represent you toward ECHA and the registration consortium
Act as the primary contact for ECHA, your importers, and downstream users
Manage the REACH-IT account in our name on your behalf

Technical work

Identify which REACH requirements apply to your substances and tonnage band
Evaluate your scientific and technical data; identify gaps
Plan, arrange, and monitor laboratory testing where data is missing
Prepare and submit the registration dossier
Prepare the Chemical Safety Report (CSR) for substances above 10 tonnes/year
Compile Safety Data Sheets aligned with the registered data

Ongoing compliance

Manage post-registration notifications and ECHA compliance checks
Coordinate consortium correspondence and Letter of Access updates
Maintain annual tonnage records and downstream user lists
Update the dossier when your tonnage band, formulation, or use scenarios change

The six-step appointment process

Scoping. You share substance identity and expected annual tonnage band.

Quotation. We send an OR service quote and, if needed, a registration cost estimate covering Letter of Access and ECHA fees.

Appointment. You sign the Only Representative Service Agreement.

Onboarding. We set up the REACH-IT account, gather your data, and coordinate consortium membership.

Dossier. Data assessment, testing plan, dossier preparation, submission to ECHA.

Ongoing compliance. CSR and SDS alignment, tonnage and downstream-user updates, responses to ECHA and consortium requests as they arrive.

Typical timeline: one to two weeks from first contact to a signed appointment, three to six months from appointment to a submitted registration dossier. Tonnage band and data availability are the two factors that move that range.

How to choose a REACH Only Representative

The OR holds your registration, signs your dossier, and represents your company to ECHA. The wrong choice exposes you to compliance failures, fines, and lost market access. Six criteria separate a qualified OR from a postal-address-with-a-consultant-attached.

✓ EU legal status

The OR must be a natural person or legal entity physically established in the EU

✓ Experience and expertise

Choose an OR with extensive REACH experience, familiar with the full registration and post-registration process. Prefer providers who have been in the industry for a long time and have a long record of successfully representing non-EU suppliers

✓ Qualifications and accreditations

Do check if the OR has a team of competent specialists who possesses relevant chemistry & toxicology background and REACH expertise to handle all OR tasks

✓ Communication and language skills

Work with an OR that is responsive, transparent and clear in communication, capable of providing regular updates, and fluent in English and other relevant languages. Proficiency in REACH and scientific terminology is crucial to ensure the quality of REACH works

✓ Services, pricing, and contract

Review the OR’s service scope, avoid one-size-fits-all solutions. Select those offering tailored services to your project, clear and lawful contracts, and transparent pricing

✓ References and reviews

Check feedback from previous clients to assess reliability, competence, and professionalism

Selecting a qualified OR helps ensure REACH compliance and prevents legal and financial issues. Non-EU suppliers should therefore try to ascertain that their future OR partner is competent and reliable. Choose one with solid experience, proven qualifications, clear communication, tailored services, transparent pricing, and positive client reviews.

Common mistakes when appointing an OR

✕ Choosing by price alone:

The cheapest option may lack competence, fail to show potential costs, leading to higher long-term expenses

✕ Not verifying experience:

Insufficient expertise can lead to poor dossiers, delays, or non-compliance

✕ Ignoring communication skills:

Weak communication may result in errors or missed deadlines

✕ Skipping references and reviews:

Always check reviews to confirm the OR’s reliability

✕ Accepting a vague offer:

Demand a detailed offer covering detailed scope, timelines, and pricing

✕ Overlooking service range:

A limited scope OR can cause extra cost, workload, and delays

Avoiding these issues increases your chances of partnering with a capable OR who can maintain REACH compliance effectively.

FAQs: REACH Only Representative

Do non-EU manufacturers need an Only Representative?

Yes, they do. If your substances (alone, in mixtures, or in articles with intended release) are placed on the EU/EEA market, as a non-EU supplier, you cannot register directly. Instead, REACH regulation (Article 8) allows you to appoint an EU-based entity who acts as your Only Representative. Your OR will fulfill all REACH duties of the importers. Your EU importers become downstream users.

Who can act as an Only Representative under REACH?

An EU-established natural or legal person with sufficient background and competence  to manage scientific data assessment, dossier preparation & submissions, and post-registration duties (Article 8).

Can a REACH Only Representative represent multiple companies?

Yes. Under REACH, an OR can legally represent multiple non-EU manufacturers.

Can we change our EU REACH OR later?

Yes. Changing an OR is legally permitted under REACH and follows a defined transfer procedure covering ECHA notification, dossier handover, and REACH-IT account migration. See our guide on changing your Only Representative for the full process.

How does UK REACH affect my obligations?

EU and UK REACH are separate. If you sell in Great Britain, you may require a UK-based OR and separate registrations.

How much does an OR cost?

OR fees depend on three variables: the number of registered substances, the tonnage band per substance, and the number of EU importers covered. The dominant cost is usually the Letter of Access fee charged by the registration consortium, which is set by the lead registrant, not by the OR. Chementors provides itemised quotes covering OR service fees, registration costs, consortium fees, and ECHA fees as separate line items, so you can see exactly where the budget goes.

What's the difference between a REACH Only Representative and an importer?

The OR is the EU-established legal entity appointed by a non-EU manufacturer to act as the registrant under Article 8. The importer is any EU company that physically brings a substance into the EU. Once an OR is appointed, importers are reclassified as downstream users — they no longer have registration obligations, and the substance can flow into the EU through any importer covered by the registration.

What happens if a non-EU manufacturer sells into the EU without an OR?

The substance is non-compliant under REACH and cannot legally be placed on the EU market. ECHA and national authorities can require removal. Importers face fines and customs blocks. The non-EU manufacturer risks reputational damage and a complete loss of EU market access — which is harder to recover than the cost of appointing an OR in the first place.
