Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If silver iodide for photographic emulsions
Silver compounds like silver iodide are specifically classified under heading 2843 for precious metal salts.
If used as a catalyst in organic synthesis
Spent catalysts or reaction accelerators containing iodides may shift to Chapter 38 for chemical reaction products.
If inorganic pigments for paints
Iodide-based luminophores or pigments are excluded from Chapter 28 per notes and go to heading 3206.
