SITCSection 7
U.S. imports of parts for rubber or plastics working machinery (n.e.s.) (SITC 72852) totaled $90.7M in April 2026, traded with 65 countries.
Importers of Parts for Rubber or Plastics Working Machinery (N.E.S.) paid $12.1M in duties in April 2026 — an effective duty rate of 15% on $78.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Parts for Rubber or Plastics Working Machinery (N.E.S.) imports of $90.7M in April 2026 ran 23% below the year-to-date monthly average of $118.0M.
Last updated: April 2026 dataDedicated replacement parts — screws, barrels, molds, hydraulic components, and control assemblies — for the extruders, injection molders, blow-molding machines, and other rubber- and plastics-processing equipment classified under the parent heading are covered here. Correct classification of these parts depends on demonstrating that they are principally designed for rubber or plastics machinery rather than for general industrial use. Section 301 tariffs that apply to Chinese-origin machinery in the parent heading generally extend to dedicated parts as well, making origin documentation important for cost planning.

Not automatically. A generic hydraulic cylinder suitable for many industrial applications would typically be classified under a general hydraulic-components heading rather than here. Only parts that are identifiable as designed principally for rubber or plastics machinery — by design features, tolerances, or OEM designation — qualify for this heading. Documentation from the machine manufacturer linking the part to a specific plastics-processing machine is the key supporting evidence.
Misclassification can result in underpayment or overpayment of duties, potential CBP penalties, and delays at the port of entry. Given that Section 301 tariffs may apply differently across headings for Chinese-origin goods, the duty impact of a classification error can be significant. Importers should obtain a binding ruling from CBP for high-volume or high-value part imports where classification is ambiguous.
