Sulfur (elemental) under REACH

S8 · 硫磺

Status: Registered. Sulfur is fully registered under REACH at the highest tonnage band (>1,000,000 tonnes/year). **Distinguishing pattern: Production via Claus process at refineries and sour-gas plants (recovered sulfur from H2S in petroleum refining + natural-gas sweetening + tar-sands upgrading) accounting for the dominant share of global production (verify Claus-process share against ICIS or USGS Mineral Commodity Summaries before quoting); minimal residual Frasch-mining production + completes sulfur chain upstream of sulfuric acid batch 2 plus ammonium sulfate batch 31 plus diammonium phosphate batch 30 plus sodium hypochlorite batch 65 (S → SO2 → SO3 → H2SO4 contact-process Haber-equivalent for sulfuric chain) + sulfuric-acid feedstock primary use (~60% of global sulfur consumption, verify against ICIS) plus phosphate-fertiliser sulfuric-acid input plus rubber vulcanisation plus fungicide / pesticide active plus pharma plus pyrotechnic plus battery (Li-S developmental) downstream chains + low-to-moderate hazard profile (Flam. Sol. 2 at fine-powder grade per harmonised CLP entry; verify exact harmonised classification against ECHA Annex VI to CLP Table 3.1 before relying).** No harmonised CLP entry for solid block / lump sulfur; ECHA C&L Inventory aggregates notifier classifications: Flam. Sol. 2 at fine-powder grade only (verify against ECHA https://echa.europa.eu/information-on-chemicals before relying). NOT SVHC. NOT Annex XIV. NO active EU AD case on Chinese-origin sulfur currently (verify against EUR-Lex https://eur-lex.europa.eu/ before invoicing); however, **note that China is structurally net-IMPORTER of sulfur (~30% of global sulfur trade flows into China for sulfuric-acid + phosphate-fertiliser captive consumption, verify against ICIS or S&P before quoting); EU sulfur trade flows are not the dominant story**.

Sulfur is fully REACH-registered with **low-to-moderate hazard profile** (Flam. Sol. 2 at fine-powder grade; solid block / lump typically unregulated). NOT SVHC, NOT Annex XIV. NO active EU AD. **Production: Claus-process at refineries and sour-gas plants dominant** (recovered sulfur from H2S). **Closes sulfur chain upstream of H2SO4 + AS + DAP + NaOCl**. **China is structurally net-IMPORTER of sulfur** (~30% of global trade flows into China). Sulfuric-acid feedstock (~60%) + phosphate-fertiliser + rubber vulcanisation + fungicide / pesticide + pharma + pyrotechnic + Li-S battery downstream chains. EU PPP + BPR + Ph.
