Standard International Trade Classification
U.S. imports of Numerically Controlled Punching or Notching Machines (Including Combined Punching & Shearing) (SITC 73316) totaled $20.9M in August 2026, imported from 18 countries.
Importers of Numerically Controlled Punching or Notching Machines (Including Combined Punching & Shearing) paid $2.2M in duties in August 2026, an average duty rate of 10.67% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataCNC turret punch presses, single-head punching machines, and combined punch-shear centers under SITC 73316 are core sheet metal fabrication tools, capable of producing complex hole patterns, notches, and formed features in a single automated setup—making them central to enclosure, electrical panel, and HVAC duct manufacturing. The explicit inclusion of combined punching-and-shearing machines distinguishes this heading from the shearing-only categories (73314 and 73315), and the NC requirement separates it from manually operated punch presses classified elsewhere. Turret capacity (number of tool stations), maximum punching force, and sheet-size handling range are the primary specifications driving capital investment decisions for this equipment class.

A machine with an integrated shearing station classifies under 73316 (combined punching and shearing, numerically controlled) rather than under the shearing-only headings. The combined-function design is the decisive factor—73316 explicitly captures machines that perform both punching and shearing, and the NC control requirement is met by the CNC turret control system.
Importers should include the OEM technical specification sheet listing turret capacity, punch force rating, and control system model, along with a commercial invoice that separately values any included tooling sets. Tooling (punches and dies) shipped with the machine may be classifiable separately from the machine itself, and bundling them without itemization can complicate both classification and customs valuation.
