Import Tips
• Include NACE MR0175 compliance certification for sour service to support drilling tubing classification
• Measure and certify exact OD/wall specs; exceeding 114.3 mm shifts to 7304.24.70
• Avoid pitfall of bulk packaging declaration—specify individual tubing lengths for accurate duty assessment
