Import Tips
• Document threaded couplings separately if imported unassembled to avoid set classification issues
• Ensure 'casing' terminology in commercial invoices matches drilling specifications per API standards
• Conduct material analysis for alloy content (>1.65% manganese or other elements) to distinguish from carbon steel
