Import Tips & Compliance

Connection type (BTC, VAM TOP, etc.) must be specified as it affects drill pipe classification

Minimum wall thickness certification required; partial penetration welds disqualify from seamless category

Country of melt and manufacture documentation critical for alloy steel verification
