HS Code for CIP machine

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.

Products Included

• Wet-bag cold isostatic presses
• Dry-bag cold isostatic presses
• Isostatic pressing equipment for ceramics
• Powder metallurgy isostatic presses
• High-pressure cold forming presses

Common Misclassification

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.

FAQ

What is the HS code for CIP machine?

The HS code for a Cold Isostatic Press (CIP) machine is 8479.83.

Does this code include Hot Isostatic Presses (HIP)?

No, 8479.83 is specific to "cold" isostatic presses. Hot Isostatic Presses, which involve high-temperature heating elements, are typically classified under 8479.89.
