REACH Compliance And Manufacturing Readiness: What Hardware Startups Need To Know

If you’re building hardware for the UK or EU, there is a specific nightmare that hits at the worst possible time, right as your first shipment reaches customs.

You’ve checked the PCB. You’ve got the battery certs; and now you’re confident because you think you’re good to go, but then a customs agent asks for your REACH data. Suddenly, your container is flagged, your launch is dead in the water, and you’re looking at a compliance gap you didn't even know existed.

At Ardencraft, we see this happen a lot. Founders assume that if their product is "safe," it’s compliant. But in mass production, "safe" is just a feeling. REACH is the law.

Another concern is that people mix up RoHS and REACH a whole lot.

What is REACH

REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) is a broad regulation that applies throughout the product lifecycle, from design and manufacturing through to market introduction. It covers substances present in materials, components, coatings, adhesives, flame retardants, and even chemicals used during manufacturing processes, such as cleaning agents and surface treatments.

On the other hand, RoHS (Restriction of Hazardous Substance) is a regulation that limits the amount of certain hazardous materials that can be used in electrical and electronic products sold in many markets, particularly the European Union.

Why REACH Matters

The significance of REACH lies in the fact that merely proving product safety is insufficient. Manufacturers, importers, customers, retailers, and customs authorities demand clear evidence of material compliance and traceability throughout the supply chain. 

The 0.1% Trap

This is the part where most teams get stuck.

In REACH terms, you can not hide a bad chemical by averaging it out. If your device weighs 1kg but contains a small component that exceeds the applicable REACH threshold for a restricted substance, that individual component can create compliance obligations regardless of the overall weight of the finished product. Some substances are regulated at extremely low concentrations, making detailed material-level analysis essential. 

The 4 Biggest REACH Traps in 2026

1. The "Supplier Letter" Illusion

Some factories in Shenzhen or Vietnam will hand you a PDF that says "We are REACH compliant." In 2026, that is just a piece of paper. If a customer, retailer, logistics partner, customs authority, or regulatory body requests for a Full Material Disclosure (FMD) and your supplier is unable to provide the chemical breakdown of the specific resin used in your casing, a generic declaration may not suffice. You will need up-to-date supporting documentation(SGS/TUV) and traceable compliance data.  

2. The Moving Goalposts

The Candidate List of Substances of Very High Concern (SVHCs) is updated regularly. Following the latest update on February 4, 2026, the list now officially stands at 253 entries. A product that was "legal" when you finished your design last year might be non-compliant today.  

For the most up-to-date list, manufacturers should refer to the Candidate List published by the European Chemicals Agency (ECHA), which administers REACH requirement: https://chem.echa.europa.eu/obligation-lists/candidateList

If you aren't auditing your solvents and flame retardants every six months, you’re gambling with your shipment.

3. The Coating & Adhesive Blindspot

Founders often focus heavily on the main PCB board, but securing REACH compliance for hardware frequently requires looking at less obvious sub-components. ECHA's recent addition of n-hexane and bisphenol AF highlights just how heavily common production materials are being targeted:

• Adhesives: Gasket and assembly adhesives may contain restricted plasticisers or other regulated substances.

  
  

• Coatings: Soft-touch finishes, paints, anti-corrosion treatments, and surface coatings can introduce compliance risks.

  
  

• Cables: PVC insulation is a common source of restricted phthalates.

  
  

• Metals and Raw Materials: Material contamination can occur much earlier in the supply chain, including during mining, refining, recycling, plating, and material processing activities. Without proper supplier traceability, restricted substances can find their way into other well-designed products.

4. The Digital Product Passport (DPP)

The EU is moving toward mandatory Digital Product Passports. This means your compliance data must be digitally accessible and transparent. If you haven't built a "Living BOM" that tracks chemical compliance, you aren't just risking a fine, you’re risking being locked out of the market entirely.

How We Handle REACH at Ardencraft

We don't wait for customs to find a problem. Over here, we scrub the Bill of Materials (BOM) during the design phase:

• Get the FMD: We don't settle for "Pass" letters. We get the material breakdown to the PPM (parts per million) level.

• Check CAS Numbers: We verify the chemicals against the latest official list.

• Article Weight Math: we calculate the percentage based on the individual part, not the whole device.

• SCIP Database: We ensure that any substance above 0.1% is properly registered in the SCIP database so the product is legally sold.

Conclusion 

REACH isn't a legal hurdle; it’s a manufacturing reality. Customs authorities are getting much faster at auditing material disclosures.

We tell our partners: If you can’t prove what your product is made of, you don't actually own your supply chain. It’s significantly cheaper to scrub your BOM today than it is to deal with a product recall tomorrow.

FAQ

Q. Is RoHS enough? 

No. RoHS and REACH address different risks. RoHS restricts a defined set of hazardous substances in electronics, while REACH applies more broadly to substances used throughout products and supply chains, including materials, coatings, adhesives, and packaging 

Q. Does this apply to the UK? 

Yes. We have "UK REACH." It currently mirrors the EU list, but you still need the specific paperwork to prove you’re compliant on both sides of the channel.

Q. What happens if I ignore it? 

Your goods get seized at the border. In some EU states, fines can hit 4% of your annual turnover. It’s not worth the risk.

Q. How often should I check? 

The list updates every January and June. We recommend a full BOM scrub every six months, or anytime you change a sub-supplier for plastics or coatings.
