Import Tips
• Include detailed dimensional specs (OD, weight per foot) and coupling type (e.g
• STC) in commercial invoice
• Ensure end-user declaration specifies oil/gas drilling to prevent reclassification as general pipe
• Watch for anti-dumping duties on certain origins; verify with CBP for country-specific rates
