HS Code for Silver iodide

Silver iodide is classified under HS code 2843.29, which specifically covers silver compounds other than silver nitrate. This classification is determined by the chemical composition of the substance, which consists of silver and iodine. Within Chapter 28 of the Harmonized System, which deals with inorganic chemicals and precious metal compounds, heading 2843 is reserved for colloidal precious metals, inorganic or organic compounds of precious metals, and amalgams of precious metals. Since silver iodide is an inorganic compound of a precious metal (silver), it must be categorized here. Subheading 2843.21 is dedicated solely to silver nitrate, leaving 2843.29 as the residual category for all other silver compounds, including halides like silver iodide. The classification remains consistent regardless of the physical form, whether it is a fine powder or incorporated into a specialized delivery system for industrial applications. The General Rules for the Interpretation (GRI) of the Harmonized System dictate that products should be classified according to the terms of the headings and any relative section or chapter notes. Chapter 28 Note 1 generally limits the scope of the chapter to separate chemical elements and separate chemically defined compounds. Silver iodide fits this description perfectly as a chemically defined compound of silver used in photography and meteorology.

Common Misclassification

Silver iodide is frequently misclassified under HS code 2843.21, which is reserved exclusively for silver nitrate. Another common error is using HS code 2827.60, which covers other iodides of non-precious metals. Because silver is a precious metal, its compounds must stay within heading 2843 regardless of the anion involved.

FAQ

What is the HS code for Silver iodide?

The HS code for silver iodide is 2843.29, categorized under silver compounds excluding silver nitrates.

Is silver iodide classified as a hazardous material for shipping?

While the HS code 2843.29 identifies the chemical nature, shipping regulations often classify it as an environmentally hazardous substance (UN3077) depending on the concentration and volume.
