Subheading 9 of 9 in heading 2812
Sulfur dichloride (SCl₂) is a reactive, unstable chlorinating agent used in specialty organic synthesis and as a precursor to certain sulfur-containing compounds in pharmaceutical and agrochemical research. Switzerland is the recorded US import supplier, consistent with the Swiss fine-chemicals sector's role in producing low-volume, high-purity reactive intermediates. Because this heading has no enumerated children in the current US schedule, importers should verify the operative 10-digit classification with a licensed customs broker before entry. SCl₂'s instability and corrosivity require careful cold-chain and moisture-exclusion protocols during transport.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Sulfur dichloride (SCl₂, HTS 281216) and sulfur monochloride (S₂Cl₂, HTS 281215) are distinct chemical species with different molecular formulas, CAS numbers, and reactivity profiles. They are separately enumerated at the HS 6-digit level. Importers should confirm the exact compound identity — ideally by CAS number — on commercial invoices to ensure correct classification, as the two are sometimes confused in trade documentation.
SCl₂ is thermally unstable and tends to disproportionate to S₂Cl₂ and Cl₂ over time, especially at elevated temperatures. This means shipments typically require refrigeration, inert-atmosphere packaging, and rapid transit. Importers should coordinate closely with freight forwarders experienced in reactive halide logistics and confirm that port-of-entry storage facilities can maintain required conditions.
