HS Code 2843.29 – Silver compounds; excluding silver nitrates
HS code 2843.29 is the 6-digit subheading for silver compounds, excluding silver nitrates. It is used for silver chloride, silver bromide, silver iodide, silver oxide and silver sulfate.
What HS 2843.29 covers
This category encompasses all silver compounds, with the explicit exclusion of silver nitrate (which has its own code). It's a diverse group including silver halides (chloride, bromide, iodide), silver oxides, silver sulfates, and many other inorganic and organic silver compounds. These materials find extensive applications across various sectors: photography (especially silver halides for film), electronics (conductive pastes, contacts), medicine (antimicrobial agents, wound dressings), mirrors, and specialized coatings. Key players in this trade are chemical producers, electronics manufacturers, and companies specializing in precious metal refining and compounding. The specific compound dictates its value, volume, and industrial application, making this a varied and important trade category.

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).
