REACH Compliance for CNC Machined Components

REACH compliance for CNC machined components comes up more often than sourcing managers expect, because REACH doesn’t just apply to chemicals in a drum — it applies to substances present in a finished machined part above a set threshold. Regulation (EC) No 1907/2006 (REACH) requires EU suppliers to identify and communicate the presence of Substances of Very High Concern (SVHCs) in any article, including metal brackets, housings, and fasteners. This guide covers what REACH actually requires for machined parts, which materials draw the most scrutiny, and how to verify a supplier’s compliance before a shipment gets held at customs.

What REACH Actually Requires for Machined Parts

REACH requires suppliers to notify the European Chemicals Agency (ECHA) and inform downstream customers when an SVHC is present above 0.1% weight by weight in an article. The SVHC Candidate List currently runs to 253 substances and is updated twice a year, so a component that was compliant last year can require a fresh review after the next update. Since 2021, articles containing an SVHC above that threshold sold in the EU also need to be reported to the SCIP database, regardless of whether RoHS applies to the same product.

REACH-Compliant vs Non-Compliant Machined Components

Factor	REACH-Compliant Component	Non-Compliant Component
SVHC concentration	Below 0.1% w/w, or declared if above	Present above threshold, undeclared
Supporting documentation	Supplier declaration, SCIP reference where required	None provided or unverifiable
Candidate List monitoring	Reviewed against current biannual update	Based on outdated or one-time check
Market eligibility	Sellable as an article in the EU/EEA	Creates compliance and customs risk

Practical Examples by Industry

Electronics enclosures: aluminum housings machined and declared free of Candidate List substances above the notification threshold.
Connector components: leaded brass pins reviewed against the current SVHC list, since lead metal itself has been listed since 2018.
Robotics & automation parts: stainless and aluminum brackets supplied with REACH declarations for EU-bound assemblies.
Automotive & EV components: machined parts requiring both supplier declarations and SCIP database references for regulated builds.

Materials That Affect REACH Compliance for CNC Machined Components

Brass and leaded copper alloys require the closest review, since lead metal has been on the SVHC Candidate List since 2018 and free-machining grades commonly rely on it. Aluminum and stainless steel generally present fewer REACH concerns, though surface treatments and coatings should still be checked against the current Candidate List rather than assumed safe by default.

How to Verify REACH Compliance Before You Order

Verifying REACH compliance for CNC machined components starts with a written declaration tied to the specific alloy and finish, not a blanket “REACH compliant” claim. Ask whether the supplier reviews the Candidate List on each update cycle, and confirm SCIP reporting has been filed where the threshold applies. Suppliers holding documented quality certifications are generally better positioned to track this kind of regulatory change consistently.

FAQ: REACH Compliance for CNC Machined Components

Does REACH apply to machined metal brackets and housings?

Yes — REACH treats any manufactured item, including machined metal parts, as an “article” subject to SVHC notification duties above the 0.1% w/w threshold.

Is lead currently restricted under REACH for machined parts?

Lead metal has been on the SVHC Candidate List since 2018, which triggers communication obligations rather than an outright ban, though this differs from RoHS restrictions on lead in electronics.

What is the SCIP database and does it apply to CNC parts?

SCIP is an ECHA database for articles containing SVHCs above 0.1% w/w sold in the EU; machined components meeting that threshold need to be reported regardless of other regulations like RoHS.

How often does the REACH SVHC list change?

ECHA updates the Candidate List roughly twice a year, so a component’s compliance status should be reviewed periodically rather than checked once and assumed permanent.
