Last updated: April 2026 dataCold isostatic presses (CIPs) apply uniform hydraulic pressure from all directions at ambient temperature to compact powdered metals, ceramics, and advanced composites into near-net-shape preforms — a critical step in aerospace, defense, and hard-metal tooling supply chains. The entire heading resolves to a single 10-digit line (8479830000), simplifying classification but not necessarily duty exposure: imports from China are subject to Section 301 tariffs, while Sweden, the United Kingdom, and Germany — all significant suppliers — face a different tariff environment. Buyers sourcing CIPs should confirm the vessel's working pressure rating and chamber dimensions in commercial documentation, as these specifications affect both end-use suitability and potential export-control review on re-export.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Cold isostatic presses operate at room temperature using liquid as the pressure medium and classify under 8479830000. Hot isostatic presses (HIPs), which apply heat simultaneously with pressure, classify elsewhere in Chapter 84 and are not covered by this heading — importers should confirm operating temperature specifications before filing entry.
Yes. Imports of cold isostatic presses originating in China are subject to Section 301 tariffs in addition to the standard MFN duty rate. Importers should verify the current Section 301 list status and any applicable exclusions with a licensed customs broker before entry.
