Import Tips
• Include material certification (e.g
• 304 SS) to claim lower duties; unverified stainless may default to higher carbon steel rates
• Ensure declaration specifies 'lag screw' to distinguish from coach screws, avoiding reclassification
• Bundle in original manufacturer packaging to demonstrate commercial quantity and prevent retail set scrutiny
