Import Tips
• Submit detailed dimensional certificates confirming OD between 215.9-285.8 mm and wall ≥12.7 mm; customs often audits via caliper measurements
• Label as 'oil well casing' not generic pipe to prevent reclassification; include IADC drilling specs
• Watch for anti-dumping duties on certain origins—check USTR lists for Chinese/Indian steel
