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
