Import Tips
• Provide detailed engineering drawings showing thread/shank dimensions >6mm to support classification during CBP review
• Avoid common pitfall of classifying with hex head bolts under steel codes; highlight aluminum purity via spectrochemical analysis
• For alloyed aluminum, ensure documentation shows Al predominates over other elements per subheading note (b)
