Import Tips
• Label with exact HTS statistical suffix based on diameter; importers often overlook 0.1mm differences affecting rates
• Ensure documentation shows cold-heading quality grade suitable for fasteners to support end-use claims if needed
• Avoid bundling with fittings; sets classify differently under composite goods rules
