Import Tips
• Provide detailed threading specs (e.g
• BTC, STC) and coupling data in entry docs to distinguish from tubing
• Label as 'drilling casing' explicitly; generic 'steel pipe' invites scrutiny under 7306 other welded pipes
• Watch for country-of-origin rules; many suppliers from China/India require Section 232 steel tariffs verification
