Import Tips

• Verify API 5CT certification and exact wall thickness measurements to confirm HTS classification; provide mill test certificates (MTC) showing alloy composition

• Ensure couplings meet API STC standards to avoid reclassification as uncoupled tubing

• Watch for anti-dumping duties on Chinese-origin seamless pipes
