Question: My company uses parts made entirely from stainless steel. We have not been able to get declarations of compliance from the supplier of these parts, but I have heard that stainless steel is automatically compliant with a number of regulatory requirements. Is this accurate?
Answer: Common industry standard grades of stainless steel, such as 304 or 316, comply with requirements under a number of common regulations. They typically will not contain regulated levels of substances listed under:
- EU Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH) Candidate List of substances of very high concern (SVHCs).
- EU REACH Annex XIV.
- EU REACH Annex XVII.
- EU Restriction of Hazardous Substances (RoHS) Directive.
- EU Battery Directive (Directive 2006/66/EC).
- The Safe Drinking Water and Toxic Enforcement Act (California Proposition 65).
If you are relying on this information to establish regulatory compliance, however, it is essential to first confirm that any parts in question are made entirely of ASTM grade 304 (also known as SAE 304, UNS S30400, 18/8, or A2) stainless steel or ASTM grade 316 (also known as SAE 316, A4, surgical, or marine-grade) stainless steel.
