Import Tips
• Specify exact NPT threading gauge (e.g
• 11.5 TPI) in commercial invoice to match US plumbing norms
• Conduct pre-shipment inspection for thread accuracy to prevent rejection under Buy America provisions for public projects
• Bundle with matching pipe sizes in shipments but declare separately to avoid set classification issues
