Subheading 847790 · $96.2M of $240.3M
U.S. imports of parts of machinery for working rubber or plastics (HS 847790) totaled $96.2M in July 2026, traded with 68 countries.
Importers of Parts of Machinery for Working Rubber or Plastics paid $12.8M in duties in July 2026 — an effective duty rate of 15% on $86.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataReplacement and service parts for the full range of rubber and plastics processing machinery — from injection-molding machine bases and platens (8477902540, 8477902580) to barrel screws (8477904501), hydraulic assemblies (8477906500), and extruder components (8477900020, 8477908620) — are classified across a detailed set of US tariff lines under this subheading. Germany and Canada lead US supply, with Italy, China, and Japan also significant. Correct parts classification requires identifying the parent machine type, as the schedule maintains parallel lines distinguishing parts of injection-molding machines, extruders, blow-molding machines, and tire-forming equipment.

Barrel screws are specifically enumerated under 8477904501 regardless of whether they serve an injection-molding machine or an extruder. However, other structural parts — such as bases, beds, platens, and clamp cylinders — are split between lines dedicated to injection-molding machines (8477902540) and a residual NESOI line (8477902580), so the parent machine type does matter for those components.
Parts must be classifiable as suitable for use solely or principally with a specific machine to be classified under heading 8477 rather than as a general hydraulic component under heading 8412 or 8484. If the cylinder is a standard commercial item used across multiple machine types, it may not qualify as a dedicated part of plastics machinery. Importers should obtain manufacturer documentation confirming the part's design specificity before classification.
