Import Tips
• Verify exact thread diameter under 6 mm with calipers to confirm classification under 7318.14.10; larger sizes shift to 7318.14.50
• Provide material test reports confirming iron or steel composition to avoid reclassification under non-ferrous chapters
• Label packages clearly with screw size, type (self-tapping), and quantity to facilitate customs inspection and prevent undervaluation penalties
