Product classification
HS code for CIP machine: 8479.83
Machines and mechanical appliances, cold isostatic presses.
Classification of CIP machine under HS 8479.83
Cold Isostatic Press (CIP) machines are classified under HS code 8479.83. This code is situated in Chapter 84, which deals with nuclear reactors, boilers, machinery, and mechanical appliances. Specifically, 8479 covers machines and mechanical appliances having individual functions, not specified or included elsewhere in the chapter. Sub-heading 8479.83 was specifically introduced to account for "cold isostatic presses." These machines function by applying high pressure from all sides (isostatic) using a liquid medium (usually water or oil) at ambient temperatures to compact powders into solid shapes. The classification is based on the machine's unique mechanical function of pressure application for material forming, which is distinct from standard hydraulic presses or metal-working machine tools.

Codes often confused with 8479.83
Common mistake. CIP machines are often misclassified under 8462.90 (other machine tools for working metal by forging or pressing). However, because CIPs are often used for ceramics, plastics, and composites—not just metal—and because they use a fluid medium for pressure rather than a mechanical die, 8479.83 is the more accurate classification. They may also be confused with Hot Isostatic Presses (HIP), which are classified under 8479.89 or 8419 if the heating function is primary.
Top exporters and importers of HS 847983 (the code used for CIP machine), 2025
In 2025, the largest exporter of HS 847983 (the code used for CIP machine) in UN Comtrade data was the United Kingdom, with 21% of world exports; the largest importer in UN Comtrade data was the United Kingdom, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
