USGS Mineral Commodity Summaries 2026 revises 2024 Canada sulfur production to about 5.06 million tonnes and world output near 83.9 million tonnes. MCS 2025 had used about 85 million tonnes world and Canada about 5.0 million tonnes as estimates. The PDF is at https://pubs.usgs.gov/periodicals/mcs2026/mcs2026-sulfur.pdf. Soft unit values persisted before the 2025 Tampa climb from $116 per long ton toward $310.
US all-forms production in the same summary is 8.32 million tonnes in 2024, down from 8.65 million in 2023. Apparent consumption 9.36 million tonnes. Average US elemental sulfur unit value $46.42 per tonne, after $58.9 in 2023 and $177.8 in 2022. 2024 is the soft year on the USGS tape. 2025's $180 unit-value is the rebound.
Alberta recovered sulfur still leaves mainly through the Vancouver stem. VFPA lists 2024 sulphur at about 3.35 million tonnes, up 8 percent from 3.10 million in 2023. Argus separately reported 2024 Vancouver solid exports up 7 percent to 3.3 million tonnes, supported by de-blocking and prilling initiatives, plus about 900,000 tonnes of Canadian liquid rail into the United States.
Canada's 5.06 million tonne recovered book is output. Vancouver's 3.35 million is the Pacific solid slice. The 900,000 tonne molten-rail slice is the US phosphate and industrial book that USGS later counted inside Canada's 53 percent of US elemental imports for 2021-24. The rest is domestic use and pour to block.
Tampa opened 2024 at $69 per long ton, rose to $81 in early March, eased to $76 in early July, then jumped to $116 in the fourth quarter, USGS MCS 2025. That $116 close is the setup for 2025, not 2024's average. The $46.42 unit-value is the year's mean. Two different prices, one soft year.
CRU's later inventory essay said Canada remelt accelerates when Vancouver FOB clears high logistics costs, while Kazakh and Saudi stock draws continued through the lower-price surplus for regulatory and storage-capacity reasons. 2024 Vancouver FOB averaging only $78 in January-July, in the later Argus window, did not clear the $150-plus remelt chain the way 2025's $238 would. De-blocking still happened where forming capacity allowed, including South Cheecham after May.
World 83.9 million tonnes versus a later 84 million in 2025e is a flat Claus planet. The 2025 deficit CRU put near 1.9 million tonnes is tradeable surplus disappearing, not nameplate collapsing. 2024's 5.06 million tonne Canada print is the base that 2025 remelt and 2026 swing-supplier talk sit on.
