Import Tips
• Obtain mill test certificates verifying alloy steel composition and seamless manufacturing to confirm HTS classification
• Ensure dimensional compliance with OD 285.8-406.4 mm and wall thickness ≥19 mm; common pitfall is incorrect measurement leading to wrong subheading
• For pipeline use, provide end-user certificates if required for duty exemptions or preferential tariff treatment
