HS code for Arsenic trichloride: 2812.19

Arsenic trichloride and other chlorides and chloride oxides, n.e.c. in item no. 2812.

Classification of arsenic trichloride under HS 2812.19

Arsenic trichloride is classified under HS code 281219. This classification is found within Chapter 28 of the Harmonized System, which covers inorganic chemicals; organic or inorganic compounds of precious metals, of rare-earth metals, of radioactive elements or of isotopes. Heading 2812 specifically encompasses halides and halide oxides of non-metals. Subheading 281219 is designated for arsenic trichloride and other chlorides and chloride oxides, not elsewhere specified in item number 2812. This code accurately reflects arsenic trichloride's identity as a specific inorganic chemical compound, a halide of a non-metal, distinguishing it from elemental arsenic or other arsenic compounds.

Codes often confused with 2812.19

Common mistake. Arsenic trichloride is often misclassified with elemental arsenic or other arsenic compounds. Elemental arsenic is classified under 280480, as it is the pure non-metal. Other arsenic compounds, such as arsenic trioxide, fall under 281190, which covers other inorganic oxygen compounds of non-metals. The key distinction for 281219 is its specific chemical structure as a chloride of arsenic, a non-metal. Misclassification can also occur with chlorides of metals, which are typically found under heading 2827 (e.g., iron chlorides under 282739), but arsenic trichloride is a non-metal halide.

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).
