U.S. imports of hot isostatic presses (HS 851411) totaled $2.9M in April 2026, traded with 10 countries.
Importers of Hot Isostatic Presses paid $111K in duties in April 2026 — an effective duty rate of 3.8% on $2.9M in dutiable value, based on actual customs collections rather than the published tariff schedule. Hot Isostatic Presses imports of $2.9M in April 2026 ran 199% above the year-to-date monthly average of $963K.
Last updated: April 2026 dataHot isostatic presses (HIPs) apply simultaneous high temperature and uniform gas pressure to consolidate powder metallurgy parts, eliminate porosity in castings, and densify advanced ceramics — making them critical capital equipment for aerospace, medical implant, and energy sectors. Sweden and Germany dominate US imports under this heading, reflecting the concentration of HIP technology among a small number of specialized European manufacturers. Given the high unit value and bespoke engineering of these systems, procurement typically involves long lead times and detailed technical specifications rather than spot-market purchasing.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Hot isostatic presses have their own dedicated HS6 subheading (851411) and 10-digit line (8514110000), separate from resistance-heated furnaces (851419) and induction/dielectric furnaces (851420). The defining characteristic is the combination of elevated temperature with isostatic gas pressure applied uniformly in all directions — a process distinct from conventional thermal treatment alone. Equipment that applies pressure without heat, or heat without isostatic pressure, would not qualify under this specific line.
HIPs themselves are not generally subject to US import licensing, but their export from supplier countries may be controlled under dual-use export regimes (such as the Wassenaar Arrangement) given their use in advanced materials processing for defense and aerospace applications. Importers should confirm with the foreign supplier that all applicable export authorizations from the country of origin have been obtained prior to shipment.
