Import Tips

Include fracture toughness data (e.g

DWTT >85%) for high-pressure gathering lines to support tariff classification

For FERC-jurisdictional lines, maintain origin traceability to comply with domestic content rules

Separate internal flow coating from pipe classification; coatings often duty-free under 3209 if imported separately
