Gallium Powder for Thermal Management
Fine unwrought gallium powder (<100 mesh) used in thermal interface materials for electronics cooling. HTS 8112.92.10.00 covers this as 'powders' of unwrought gallium, excluding sintered or bonded forms. High purity for heat sink applications.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If pressed into pellets or shapes
Powder formed into articles becomes 'other' excluding unwrought/powder.
If dispersed in pigments for inks
Inorganic pigments containing gallium compounds shift to Chapter 32.
If for soldering paste mixtures
Gallium powder in prepared soldering fluxes or pastes goes to chemical preparations.

Import Tips & Compliance
• Specify particle size and purity in invoice to distinguish from wrought powders; use sieve analysis certificates
• Ship under inert gas to prevent auto-ignition; include UN hazard class 4.2 if applicable
• Avoid classifying as 'articles' if loose powder—customs may challenge based on packaging
