Import Tips & Compliance

• Require API 5CT Monogram Certificate and mill test reports (MTRs) showing chemical composition and mechanical properties

• Verify stainless steel grade (e.g

• 13Cr, 22Cr) meets ASTM A312/A213 standards for corrosion resistance

• Ensure threaded connections match API BTC, STC, or premium VAM specifications to avoid customs reclassification
