Origin & supply chain +
Sourced from Uzbek Gas Processing Plants
Bare Syndicate trades Uzbek Claus-process sulfur from the Mubarak GPP and Karshi facilities — both produce sulfur as a by-product of sour-gas sweetening at scale. The Mubarak unit is one of the largest sulfur recovery operations in Central Asia. Material is granulated on-site for ease of handling and minimum moisture pickup, then railed via Uzbek-CIS corridors to Black Sea or Bandar Abbas ports. Independent assays for elemental sulfur content, ash, and moisture accompany every cargo.
FAQ +
What does Claus-process sulfur recovery mean?
The Claus process converts hydrogen sulfide (H₂S) from sour natural gas or refinery off-gas into elemental sulfur in a two-stage thermal-and-catalytic reactor. Sulfur recovered this way is the dominant source of merchant sulfur globally — Uzbekistan's Mubarak GPP processes sour gas from the Mubarak field, with Claus units delivering 99.5%+ elemental sulfur for export.
What's the difference between 90%+ and 99.5%+ sulfur?
Commercial granular 90%+ is a lower-purity grade with higher ash and impurity tolerance for general fertilizer blending. Premium granular 99.5%+ is sulfuric acid plant feed and premium DAP/MAP/SSP grade — strict on ash, moisture, and metallic impurities. Crushed lump 99%+ serves rubber compounding and specialty applications.
What's the primary end-use breakdown?
Globally, ~85% of merchant sulfur feeds sulfuric acid production, primarily for fertilizer (DAP, MAP, SSP — phosphate solubilization). Remaining ~15% splits between rubber vulcanization, pulp and paper sulfites, fluorochemicals (HF feed), pharma, and agricultural sulfur.
What's typical export packaging?
Granular sulfur ships in 1.0–1.5 t jumbo bags or in 25 kg bags inside 20 ft containers, FOB Black Sea ports (Poti, Constanta) or Bandar Abbas (Iran transit). Crushed lump ships in 25 MT bulk containers. Lead time 4–6 weeks via Uzbek-CIS rail.
