SVHCs and brass, summarised for buyers and compliance teams.
The list
ECHA SVHC Candidate List under REACH — over 250 substances (early 2026), updated about twice a year.
Criteria
Carcinogenic, mutagenic or reprotoxic (CMR); persistent, bioaccumulative & toxic (PBT/vPvB); or of equivalent concern.
SVHC in brass
Lead (Pb) — added to the Candidate List in June 2018.
Threshold
0.1% w/w per article triggers the REACH Article 33 duty to communicate.
By grade
CW617N / CW602N: Article 33 required. CW724R / C11000: below threshold.

Background

What is the SVHC Candidate List?

The SVHC (Substances of Very High Concern) Candidate List is published and maintained by the European Chemicals Agency (ECHA) under the REACH Regulation. It identifies substances that are carcinogenic, mutagenic or toxic for reproduction (CMR); persistent, bioaccumulative and toxic (PBT or vPvB); or of equivalent concern. As of early 2026 it contains over 250 substances, and ECHA typically updates it twice a year.

Being on the Candidate List does not ban a substance — it triggers information duties. Under REACH Article 33, if any listed SVHC is present above 0.1% by weight in an article, the supplier must communicate this to recipients (and, on request, to consumers) so they can use the article safely.

Lead

Lead on the SVHC list

Lead and lead compounds are SVHCs — metallic lead was added to the Candidate List in June 2018. Standard free-machining brasses CW617N (~3% Pb) and CW602N (~2% Pb) both contain lead above the 0.1% threshold, so parts made from them ship with a REACH Article 33 declaration. Lead-free grades fall below the threshold and need no SVHC notification.

The ECHA Candidate List is published roughly in January and June each year. We don't wait for it to affect you to find out — our process tracks every update so the declarations we issue always reflect the current list.

01 · REVIEW

Every ECHA update

We review each new Candidate List within 30 days of publication.

02 · REASSESS

Against your grades

We reassess the alloys we supply you against the updated list.

03 · REISSUE

Within 45 days

If a change affects a supplied product, we issue updated Article 33 declarations.

FAQ

Common questions

Which SVHC is present in brass?
Lead (Pb), which was added to the REACH Candidate List in June 2018, is present in leaded brass grades above the 0.1% threshold. Lead-free grades such as CW724R and C11000 do not contain a listed SVHC above the limit.
What is the SVHC threshold for notification?
0.1% by weight per article triggers the REACH Article 33 duty to communicate the substance to downstream users.
How does Brassland monitor SVHCs?
We review every ECHA Candidate List update (published roughly twice a year) within 30 days and reassess our grades against it, so the declarations we issue reflect the current list.
Do lead-free grades require an SVHC notification?
No. CW724R silicon brass and C11000 copper contain 0.1% lead or less and carry no SVHC notification requirement.
