Import Tips
• Include yield strength test certificates (90 KSI) but note mechanical properties don't affect HTS classification—material and form govern
• Label clearly as 'OCTG casing' to distinguish from line pipe; mislabeling common pitfall
• For re-import after use, ensure proper 9801/9802 drawback documentation
