M3 Self-Tapping Steel Screws from China
These are self-tapping screws made of iron or steel with a 3 mm thread diameter, designed for creating their own threads in pre-drilled holes. They fall under HTS 7318.14.10 due to their shank and thread diameter being less than 6 mm and self-tapping functionality. Commonly used in electronics assembly and light metal fabrication.

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
