8479.83.00.00/CIM-SIP Cold Isostatic Press/China

CIM-SIP Cold Isostatic Press from China

The CIM-SIP is a wet-bag cold isostatic pressing system used to uniformly compact powdered materials like ceramics and metals into high-density green compacts at ambient temperatures. It applies hydrostatic pressure up to 400 MPa using a liquid medium, making it ideal for producing complex-shaped prototypes and small production runs in semiconductor manufacturing. Classified under HTS 8479.83.00.00 as it is specifically a cold isostatic press for material densification.

Import Tips

• Verify machine specs confirm isostatic pressure application at ambient temps; provide manufacturer datasheet for customs

• Include end-use certification if for semiconductor processing to qualify for potential duty relief programs

• Ensure pressure vessel complies with ASME codes; common pitfall is missing hydrostatic test documentation
