Import Tips

• Verify API 5CT certification and provide mill test certificates (MTC) to confirm seamless construction and grade compliance

• Include detailed specifications on OD, wall thickness, and threading to avoid misclassification as larger diameter or thicker wall products

• Check for country-of-origin rules; anti-dumping duties may apply to certain steel pipe imports from specific countries
