Import Tips & Compliance
• Include photos or diagrams showing open ends and lack of fittings to distinguish from pipe fittings in 7307
• Confirm no internal wire rod reinforcement; products with wire exceeding 16 mm would fall under Chapter 73 wire notes differently
• Watch for overclassification as 'structural' shapes; circular welded tubes specifically match 7306.30
