HS Code 2812.19 – Arsenic trichloride and other chlorides and chloride oxides, n.e.c. in item no. 2812
HS code 2812.19 is the 6-digit subheading for arsenic trichloride and other chlorides and chloride oxides, n.e.c. in item no. 2812. It is used for arsenic trichloride, phosphorus trichloride, sulfuryl chloride, silicon tetrachloride and boron trichloride.
What HS 2812.19 covers
This HS code encompasses a diverse group of inorganic chlorides and chloride oxides of non-metals, specifically excluding thionyl chloride (2812.17) and other explicitly classified halides. Arsenic trichloride, a highly toxic compound, is a notable inclusion, finding niche applications in semiconductor manufacturing and as a dopant. Beyond arsenic trichloride, this category captures a range of other specialized inorganic chlorides and chloride oxides used as reagents, catalysts, or intermediates in various chemical processes. Importers and exporters typically include chemical manufacturers, research institutions, and specialized industrial firms dealing with high-purity materials or hazardous substances. The trade in these chemicals is heavily regulated due to their potential toxicity and corrosive properties, necessitating strict compliance with international chemical safety standards and environmental regulations. Understanding the specific chemical composition and intended use is crucial for accurate classification within this "not elsewhere specified" category.

Codes often confused with 2812.19
Common mistake. This code is a residual category for chlorides and chloride oxides of non-metals not specifically covered elsewhere in 2812, making it distinct from 2812.17 (thionyl chloride) and other specific halides in 2812.90.
Top exporters and importers of HS code 281219, 2025
In 2025, the largest exporter of HS code 281219 in UN Comtrade data was South Korea, with 31% of world exports; the largest importer in UN Comtrade data was China, with 22% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

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).
