U.S. imports of chlorides and chloride oxides of nonmetals (nesoi) (HS 281219) totaled $1.8M in April 2026, traded with 6 countries.
Importers of Chlorides and Chloride Oxides of Nonmetals (NESOI) paid $65K in duties in April 2026 — an effective duty rate of 3.7% on $1.8M in dutiable value, based on actual customs collections rather than the published tariff schedule. Chlorides and Chloride Oxides of Nonmetals (NESOI) imports of $1.8M in April 2026 ran 18% above the year-to-date monthly average of $1.6M.
Last updated: April 2026 dataArsenic trichloride (2812190010) and the broader NESOI line (2812190090) capture nonmetal chlorides and chloride oxides not specifically enumerated elsewhere in Chapter 28, encompassing specialty reagents used in semiconductor processing, catalyst manufacture, and organic synthesis. Germany leads US imports, followed by India and Japan, with South Korea and China also supplying this heading. Importers should pay close attention to the chemical identity of their product: arsenic trichloride carries distinct toxicological and regulatory implications compared to other chloride oxides classified in the NESOI line.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Arsenic trichloride is specifically enumerated at the 10-digit level (2812190010), so any shipment of AsCl₃ must be declared under that line rather than the NESOI line (2812190090). All other nonmetal chlorides and chloride oxides not specifically named elsewhere in heading 2812 fall into the NESOI line. The supplier's certificate of analysis confirming the CAS number is the key classification document.
Arsenic trichloride is a highly toxic substance subject to EPA TSCA requirements and potentially to CERCLA reportable quantity regulations. Importers should file a TSCA certification at entry and consult with environmental compliance counsel regarding any additional notification obligations tied to the volume and end-use of the shipment.
