U.S. imports of bolts, nuts, screws, rivets, washers & other turned products (standard fasteners) (NAICS 332722) totaled $500.5M in July 2026, traded with 87 countries.
Importers of Bolts, Nuts, Screws, Rivets, Washers & Other Turned Products (Standard Fasteners) paid $257.7M in duties in July 2026 — an effective duty rate of 54% on $479.2M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataStandard fasteners — hex bolts, machine screws, nuts, rivets, and washers — manufactured under NAICS 332722 are among the highest-volume traded metal components in the US market, supplying construction, automotive, appliance, and general industrial assembly. Unlike precision-turned parts, standard fasteners are typically produced to dimensional standards (ASME, DIN, ISO) that allow interchangeability, making price and lead time the primary sourcing variables. Steel fasteners in this category have been a recurring subject of antidumping and countervailing duty proceedings, and Section 232 tariffs on steel inputs add a further layer of cost consideration for both domestic producers and importers. Accurate HTS classification — distinguishing thread pitch, drive type, coating, and material — is essential because duty rates and trade remedy coverage vary significantly across subheadings.

NAICS 332721 covers custom, close-tolerance turned parts where geometry and material are specified by the buyer; 332722 covers interchangeable fasteners produced to published dimensional standards. For trade purposes, the distinction matters because standard fasteners are more likely to be covered by existing antidumping orders and are classified under well-established HTS fastener subheadings, while precision-turned parts require a more fact-specific HTS determination based on the part's function and material.
Each distinct fastener type and material combination must be classified separately at the 10-digit HTS level and declared on the entry. Mixing carbon steel and stainless steel fasteners in a single line item is a common classification error that can trigger antidumping liability on the carbon steel portion. Importers should ensure packing lists and commercial invoices itemize by product type, material, and quantity to support accurate line-by-line entry.
