U.S. imports of parts of machines for additive manufacturing (HS 848590) totaled $13.5M in April 2026, traded with 39 countries.
Importers of Parts of Machines for Additive Manufacturing paid $1.9M in duties in April 2026 — an effective duty rate of 14% on $13.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataReplacement and component parts for 3D printing and additive manufacturing equipment occupy a distinct classification under heading 8485, with the US schedule subdividing them into parts for plastic/rubber deposition machines (8485901000) and all other additive manufacturing parts (8485909000), plus a general line (8485900100). Imports from China are subject to Section 301 tariffs, making Germany and Israel — the top two supplier countries — strategically important sourcing alternatives for US buyers. Classification hinges on whether the part is dedicated to a specific additive process (e.g., fused deposition modeling vs. powder bed fusion), so precise technical documentation is essential at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The key is the specific additive process the part is designed for. Parts dedicated to machines that deposit plastics or rubber (e.g., fused deposition modeling extruder components) fall under 8485901000, while parts for other additive processes — such as powder bed fusion or stereolithography — are classified under 8485909000. Importers should retain engineering drawings and OEM documentation to support the classification.
Yes. Imports of these parts originating from China are generally subject to Section 301 tariffs. Germany and Israel, the leading suppliers under this heading, are not subject to those measures, which has influenced sourcing decisions for US manufacturers reliant on high-precision additive equipment components.
