Last updated: April 2026 dataThe 'not elsewhere specified' catch-all for tractor and motor vehicle parts captures a wide array of components — from brackets and fasteners to specialized sub-assemblies — that do not fall under more specific headings for engines, bodies, or named driveline parts. Because this residual category is frequently audited, importers must demonstrate that no more specific SITC or HTS heading applies before classifying goods here. Section 232 measures on automotive parts may apply depending on origin, and thorough technical documentation is essential to defend classification decisions.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Classification in the NES residual heading is appropriate only after systematically ruling out all more specific headings — such as those for engines, transmissions, brakes, or body parts. Importers should document this elimination process, supported by technical specifications and, where necessary, a binding ruling request to CBP.
Each line item in a mixed shipment must be classified independently on the entry. Parts that fall under named headings are declared under those codes, while genuinely residual items are declared under the NES heading. Combining them under a single code to simplify entry is not permissible and can trigger penalties.
