HS code for Silver chloride: 2843.29

Silver compounds, excluding silver nitrates.

Classification of silver chloride under HS 2843.29

Silver chloride is classified under HS code 284329, which falls within the category of inorganic chemicals. Specifically, Chapter 28 covers inorganic chemicals and precious metal compounds. Heading 2843 is dedicated to colloidal precious metals, inorganic or organic compounds of precious metals, and amalgams of precious metals. Within this heading, silver compounds are further subdivided. While silver nitrate has its own specific subheading (284321) due to its high volume of trade and industrial importance, other silver compounds like silver chloride are grouped under 284329. Silver chloride is a chemical compound with the formula AgCl, known for its low solubility in water and its sensitivity to light, making it useful in photography, electrochemistry, and as a precursor to other silver-based chemicals. For customs purposes, it is essential to distinguish between the pure metal (Chapter 71) and the chemical compound (Chapter 28). Even though it contains a precious metal, the chemical transformation into a chloride salt necessitates classification in the chemicals chapter. The classification under 284329 requires that the product be a chemically defined compound. If the silver chloride is part of a prepared photographic emulsion, it might move to Chapter 37. However, in its pure chemical form, 284329 is the correct designation. This code is also used for other silver salts like silver oxide or silver sulfate, provided they are not nitrates. Importers must provide a Material Safety Data Sheet (MSDS) or a Certificate of Analysis (CoA) to confirm the chemical identity and purity, as this affects both the classification and the potential application of hazardous material regulations during transport.

Codes often confused with 2843.29

Common mistake. The most frequent misclassification is 284321, which is specifically for silver nitrate. Another error is using 7106, which covers unwrought silver metal; silver chloride is a compound, not a metal. Additionally, if the silver chloride is in a medicinal form, it might be mistakenly placed in Chapter 30 (Pharmaceuticals).

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
