Import Tips
• Ensure the screws are classified as self-tapping, not machine screws, by verifying they cut or form threads during installation
• Declare the exact metric size (M3) and material (e.g
• carbon steel) on the CBSA documentation
• Keep records of the manufacturing process to prove self-tapping capability if challenged
