Import Tips
• Include PSL-2 quality level certificates for P110 grade to meet API drilling standards during customs review
• Document thread type (e.g
• BTC) and coupling specs to confirm 'threaded or coupled' classification
• Avoid reclassification by providing dimensional caliper reports proving OD 244-406mm range
