Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If machine screws rather than bolts
Machine screws have finer threads for precise machinery; hex bolts are coarser for structural use.
If imported as original auto equipment parts
Vehicle-specific fasteners may classify under parts of motor vehicles per end-use.
If spring washers only, without bolts
Spring washers alone fall under non-threaded similar articles.

Import Tips & Compliance
• Label shipments clearly as 'bolt kits with nuts/washers' to prevent separation during customs
• Provide tensile strength test reports; Grade 8 may trigger alloy steel scrutiny under Chapter 72
• Avoid mixing sizes in one shipment to simplify diameter verification
