8308.20 - Tubular or bifurcated rivets:

HTS Code 8308.20 specifically classifies tubular or bifurcated rivets made from base metals. These fasteners are characterized by their hollow or split shafts, designed to be deformed by hammering or pressing to create a permanent joint. They are distinct from the hooks, eyes, and eyelets covered under 8308.10, which are primarily designed for fastening or closure mechanisms on various articles. While 8308.90 encompasses other miscellaneous items within the broader 8308 heading, 8308.20 is exclusively dedicated to this specific type of rivet.

The subdivisions within 8308.20 offer further refinement based on material and finishing. Subcategory 8308.20.30.00 distinguishes tubular or bifurcated rivets made of iron or steel that have not undergone bright finishing, lathing, or machining processes. This implies a more basic or raw state of manufacture for these specific fasteners.

Conversely, subcategory 8308.20.60.00 encompasses all "other" tubular or bifurcated rivets. This includes those made from base metals other than iron or steel, or those made from iron or steel that have undergone any form of bright finishing, lathing, or machining. This residual category captures a wider variety of rivets that do not meet the specific criteria of the preceding subdivision, ensuring comprehensive classification of all goods under 8308.20.
