Import Tips
• Provide thread type specification (e.g
• BTC, STC) and coupling details in commercial invoice to confirm casing classification
• Ensure marking includes API grade, size, and weight per API 5CT standards for customs verification
• Avoid bundling with premium connections that might trigger parts classification under 8431
