Import Tips

• Obtain material test reports (MTRs) certifying chemical composition and mechanical properties to confirm alloy steel status and ASME compliance

• Ensure marking includes heat number, grade, and seamless designation per ASTM/ASME specs to avoid reclassification during customs exam

• Verify outside diameter measurement exceeds 406.4 mm with caliper certification; common pitfall is mismeasuring welded vs. seamless products
