Import Tips
• Obtain NACE MR0175/ISO 15156 certification for sour service to ensure fitness-for-service in H2S environments; critical for customs valuation disputes
• Include hydrostatic test results (>90% SMYS) in documentation to substantiate pipeline-grade strength and prevent reclassification
• Watch for anti-dumping duties on certain stainless grades from Asia; check USTR lists and file scope rulings if applicable
