Import Tips

Verify API 5ST or 5CT certification documentation to confirm OCTG suitability and avoid reclassification as general pipe

Include mill test certificates (MTC) showing stainless steel chemistry and welding process to meet 'welded of stainless steel' criteria

Declare couplings explicitly in entry docs; mismatched or separate import can trigger audits or duty adjustments
