Read Them in This Order
Qualifying a supplier is a sequence, not a checklist. Most B2B buyers move through these four steps before they are ready to send a sample or quote request.
Match the material to your market
Decide which family your demand actually needs before you compare suppliers. Start with the Material Selection Guide, then confirm the series you want in the 21-Series Catalog.
Clear the sourcing questions
Quotation bands, lead time, packing and custom-colour mechanics are usually what stalls a first order. The Sourcing FAQs answer these in plain terms.
Verify quality and paperwork
Check what QC and lot traceability look like on Quality & Traceability, then confirm which certificates are available today on Technical Documents.
Validate on your own terms
Only after steps 1–3 does a sample or a comparable volume quote mean anything. Request Test Samples or Build My Volume Quote.
