Import Tips
• Ensure threading type (e.g
• BTC, LTC) is documented; mismatches can lead to reclassification
• Provide pressure test reports and chemical composition analysis for customs verification
• Label packages clearly with HTS code, dimensions, and 'OIL WELL CASING' to prevent inspection delays
