Import Tips
• Document thread specification (UNC/UNF metric) and steel grade (M2/AISI T11342) for accurate HTS verification
• Avoid common pitfall of declaring as 'hand tap only'—most qualify as interchangeable for power tools
• Bundle with chamfer type (plug/taper/bottoming) descriptions in invoices to support classification
