HS Code 8479.83 – Machines and mechanical appliances; cold isostatic presses
HS code 8479.83 is the 6-digit subheading for machines and mechanical appliances, cold isostatic presses. It is used for wet bag CIP systems, dry bag CIP systems, laboratory cold isostatic presses, production cold isostatic presses and isostatic pressing vessels.
What HS 8479.83 covers
This code covers specialized industrial machinery known as cold isostatic presses (CIPs), which are crucial for compacting powders into high-density, uniform shapes. These machines apply pressure equally from all directions using a liquid medium, making them indispensable in advanced manufacturing sectors. Key importers are typically countries with strong aerospace, medical device, automotive, and ceramics industries, such as Germany, Japan, the United States, and China, where precision components are in high demand. Exporters often include technologically advanced nations like Germany, Switzerland, and the USA, which possess the expertise to manufacture such complex equipment. Understanding the specific pressure capabilities and chamber sizes is vital for trade, as these dictate the machine's application. The global trade in CIPs reflects the ongoing demand for high-performance materials and components, driving innovation in powder metallurgy and advanced ceramics. These machines are not general-purpose presses but highly specialized tools for material densification, often used in research and development alongside large-scale production.

Codes often confused with 8479.83
Common mistake. This code might be confused with other general pressing machines under 8479.89 (other machines and mechanical appliances) or even hot isostatic presses (HIPs) which fall under 8479.89, but CIPs specifically use a cold liquid medium.
Top exporters and importers of HS code 847983, 2025
In 2025, the largest exporter of HS code 847983 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).
