Silver Carbonate Precipitate from Germany
Silver carbonate (Ag2CO3) is a chemically defined inorganic silver salt, appearing as a yellow precipitate used in organic synthesis and as a colorant. It is classified under heading 28.43 as a silver compound, and specifically under tariff item 2843.29.00 as 'other' silver compounds, since it is not a nitrate, oxide, or halide. Chapter Note 2 excludes it from heading 28.36 (carbonates) because it is a silver compound, not a carbonate of an inorganic base.

Import Tips
• Verify the silver carbonate is chemically pure and not mixed with other substances
• Keep documentation showing it is not a carbonate of an inorganic base, as that would fall under a different heading
• Be aware of potential restrictions if used in colorants, which may require health and safety declarations
