North American Industry Classification System
U.S. exports of Precision Turned Products (NAICS 332721) totaled $98.9M in August 2026.
Importers of Precision Turned Products paid $4.7M in duties in August 2026, an average duty rate of 11.24% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataPrecision-turned components — produced on automatic screw machines, CNC turning centers, and Swiss-type lathes — serve as critical sub-assemblies in medical devices, hydraulic systems, automotive fuel systems, and defense applications. NAICS 332721 captures establishments whose primary output is close-tolerance turned parts rather than standard fasteners, with dimensional tolerances often measured in thousandths of an inch and surface finish specifications tied to functional performance. Material diversity is broad: carbon steel, stainless steel, brass, aluminum, and titanium are all common, and each carries distinct HTS classification and potentially different duty treatment. Importers of precision-turned parts should ensure that supplier quality documentation — including dimensional inspection reports and material certifications — accompanies each shipment to support both customs entry and downstream customer requirements.

Standard fasteners (bolts, screws, nuts) are classified in HTS Chapter 73 by thread type, head style, and material. Precision-turned parts that do not function as fasteners are typically classified by their material composition and end-use function — often in Chapter 73, 74, 76, or even Chapter 84/85 if they are identifiable parts of a specific machine. The functional identity of the part, not just its manufacturing method, drives HTS classification.
Importers should request a dimensional inspection report (first-article or statistical sampling), a material test report or certificate of conformance referencing the applicable ASTM or AMS specification, and — for regulated end-uses such as medical or aerospace — full traceability records linking the part to its raw material heat lot. These documents support both customs entry and downstream customer audits.
