Certifications are the compliance language of global trade. For filament buyers and resellers, four matter most.
The four key certifications
| Certification | What it covers | Why it matters |
|---|---|---|
| RoHS | Restriction of hazardous substances | Required for EU sales of electronics-adjacent products |
| CE | EU conformity | Market access for most consumer products in the EU |
| REACH | EU chemicals regulation | Filament composition must be registered-compliant |
| ISO 9001 | Quality management system | Factory process confidence for B2B buyers |
How to verify (don't trust logos)
- Ask for the certificate number and issuing body
- Check the certificate covers the exact product line you buy
- Request test reports (not just declarations) for critical markets
