European brass parts buyers: what suppliers must show

What brass parts buyers in Europe expect from suppliers: REACH and RoHS declarations, alloy certificates, dimensional reports and CE-related documents.

· 3 min read · Creston & Co

European brass parts buyers expect suppliers to show an alloy certificate, a statement on regulated substances under REACH and RoHS, a dimensional report and, where the part goes into a regulated product, supporting documents for that product's conformity. A supplier who can produce these quickly is usually ready for the European market.

Obligations fall on different parties. The importer or the manufacturer of the final product is usually responsible, so confirm the details with your compliance adviser.

The point to remember is that compliance paperwork must exist before shipment, not after. A supplier that treats it as a favour is a risk.

Alloy and material certificates

Buyers expect a certificate showing the alloy, such as the common free-cutting grades covered in brass alloys explained, with the chemistry of each batch. Lead content is the key number.

Where the part touches drinking water, read lead-free brass, because additional rules may apply to the alloy and the product.

A declaration is only useful if it names the part number and the batch. A general company letter that says all products comply is weak evidence.

REACH and RoHS statements

REACH is the EU chemicals regulation, and it places duties on companies that supply articles containing certain listed substances. RoHS limits specified substances in electrical and electronic equipment, with exemptions for lead in copper alloys up to a stated limit. Whether those exemptions apply depends on the product and the date, so check the current text.

Read whether RoHS applies to brass parts for the basics. Ask the supplier for a signed declaration that covers the substances on the current candidate list, and for test reports if you need evidence.

CE-related documents

A brass part is rarely CE-marked by itself. The CE marking belongs to the final product, such as a pressure device, a gas appliance or electrical equipment. The final manufacturer needs technical documentation about components, which can include material certificates and drawings.

Ask your customer which documents they need from component suppliers before you order. Collecting the documents later, after the factory has started production, is much harder.

Keep a file for each product with the declarations, the certificate dates and the supplier details, so you can answer a customer or a market authority within days.

Quality reports that European buyers read

Buyers expect a dimensional report on first samples and on a sampling plan during production. A coordinate measuring machine report is common for complex parts; see what a CMM report should show.

Surface finish, plating thickness and thread gauge checks should be part of the control plan. Ask for photographs of the packed goods before shipment. A supplier that does this routinely saves you disputes.

Ask also how the supplier segregates alloys on the shop floor. Mixing leaded and lead-free brass in the same swarf bins or bar racks is a classic cause of contamination, and good housekeeping prevents it.
