HS Code for Colloidal gold
Colloidal gold is classified under HS code 2843.10, which falls within Chapter 28 of the Harmonized System, covering inorganic chemicals and precious metal compounds. Heading 2843 is specifically designated for colloidal precious metals, as well as inorganic or organic compounds of precious metals. Colloidal gold consists of sub-micron sized particles of gold suspended in a fluid, usually water. The classification is driven by the chemical state of the gold; it is not in a bulk metallic form but rather a stable dispersion of particles. This subheading 2843.10 covers the colloidal form of any precious metal, but it is most frequently applied to gold and silver suspensions used in medical diagnostics, electronics, and research. The technical requirement for this classification is that the gold must remain in a colloidal state, which involves specific surface chemistry to prevent the particles from aggregating.

Common Misclassification
Colloidal gold is sometimes misclassified under HS code 3004 if it is prepared as a medicament for therapeutic use. However, unless it is put up in measured doses or in forms for retail sale for medical purposes, 2843.10 remains the correct chemical classification. It is also confused with HS code 3206, which covers coloring matter and pigments; while colloidal gold can provide color, it is classified by its chemical nature in Chapter 28. Finally, it should not be confused with HS code 7108, which covers gold in unwrought or semi-manufactured forms like bars or powder, as the colloidal state is a distinct chemical preparation.
