Import Tips
• Include yield strength test results (min 110 ksi for P110) to distinguish from lower grade alloys
• CBP requires dimensional certificates; ensure caliper measurements confirm OD 285.8-406.4 mm range
• Avoid misclassification by specifying 'casing for oil/gas drilling' vs generic tubing on commercial invoice
