Import Tips

• Document end-use with drilling contracts or buyer affidavits to counter 'general pipe' assumptions

• Specify wall thickness (e.g

• 0.5-1 inch) in invoices; thin walls risk reclassification as tubing

• Anti-dumping duties may apply from certain origins; check USTR lists for steel casing
