About HS Code 284310
This category covers colloidal precious metals, which are extremely fine particles of gold, silver, platinum, palladium, and other platinum group metals suspended in a liquid medium. These high-value, specialized materials are critical in advanced technological applications. Importers and exporters are typically high-tech manufacturers, research institutions, and specialized chemical suppliers. Key applications include catalysis (e.g., fuel cells, chemical reactions), electronics (conductive inks, sensors), medical diagnostics (e.g., rapid test kits), and nanotechnology research. Trade in these materials often involves small quantities but commands very high prices due to their purity, unique properties, and the sophisticated manufacturing processes required. Strict quality control and handling procedures are essential.
