Import Tips
• Verify API 5CT certification and provide mill test reports (MTRs) to customs for classification confirmation and quality compliance
• Ensure accurate measurement documentation for OD (285.8-406.4 mm) and wall thickness (≥12.7 mm) to avoid reclassification to thinner wall subheadings
• Check country-of-origin rules; anti-dumping duties may apply to certain steel pipe imports from specific nations like China or India
