Import Tips
• Include API 5CT grade markings and hydrotest reports in documentation to substantiate drilling casing classification
• Avoid common pitfall of incomplete thread descriptions that could lead to parts classification under 8431
• Use customs ruling requests for custom alloy blends to confirm 'other' status under 7305.20.80.00
