U.S. exports of halides and halide oxides of nonmetals (nesoi) (HS 281290) totaled $7.5M in July 2026.
Importers of Halides and Halide Oxides of Nonmetals (NESOI) paid $637K in duties in July 2026 — an effective duty rate of 20% on $3.1M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataSulfur hexafluoride (2812900010) — a dense, electrically insulating gas critical to high-voltage switchgear and semiconductor etching — is the commercially dominant product in this residual heading, alongside other nonmetal halides and halide oxides (2812900090). Germany and South Korea are the leading US suppliers, with China, India, and France also represented; Chinese-origin products in this heading may be subject to Section 301 tariffs. SF₆ is also a potent greenhouse gas regulated under EPA reporting programs, adding an environmental compliance dimension that distinguishes it from most other industrial chemicals at entry.

Yes. SF₆ is subject to EPA's Greenhouse Gas Reporting Program (GHGRP) for certain end-use sectors, including electrical transmission and distribution equipment. Importers and downstream users should assess whether their volumes and applications trigger mandatory reporting under 40 CFR Part 98 and consult environmental compliance counsel accordingly.
Only sulfur hexafluoride (CAS 2551-62-4) classifies under 2812900010. Any other nonmetal halide or halide oxide not specifically enumerated in heading 2812 falls under 2812900090. The supplier's certificate of analysis with the CAS number and molecular formula is the definitive classification evidence; misclassification between these two lines can affect duty liability and trade-remedy exposure.
