M8 Aluminum Hex Bolts from China
Hexagonal head bolts made of aluminum alloy with an M8 thread size (8 mm diameter), used for securing structural components in construction and machinery. Classified under HTS 7616.10.70 because the threads exceed 6 mm in diameter, distinguishing them from finer wire-based fasteners. These bolts meet aluminum alloy criteria with silicon and other elements exceeding purity limits.

Import Tips
• Verify aluminum alloy composition via mill certificates to confirm HTS classification and avoid reclassification as non-alloy
• Ensure threading gauge certification for dimensions over 6 mm to prevent customs disputes on shank/thread size
• Label products clearly with material content and dimensions to comply with FTC and CBP marking requirements
