Import Tips
• Specify thread standard (NPT/BSP) in invoices to prevent classification as custom machined parts
• Test reports for zinc >97.5% required; alloys per note (b) may incur different MFN duties
• Avoid pitfall of declaring as 'universal' fittings, which can lead to broader Chapter 84 appliance classification
