Year-end firmness with Alberta inventory as export buffer

Fourth-quarter 2021 kept Tampa molten contracts near $183 per long ton per USGS, ending a year that began near $69. The path reflected supply issues after pandemic refining cuts more than a permanent demand boom. BC Insight put mid-June Tampa near $192 versus about $83 in early January and $54 a year earlier. The $183 fourth-quarter USGS print is a plateau after that mid-year high, not a collapse. Argus's late-2021 price-trend review said a previously stable or soft sulfur tone gave way to firmness as DAP rallied in October and Chinese phosphate export restrictions lacked clarity. Middle East FOB strength and Brazil CFR gains reflected phosphate producers restocking sulfur ahead of constrained Chinese DAP and MAP availability.

Chinese authorities moved to restrict DAP and MAP exports after producer agreements with NDRC. Some ports halted fresh fertilizer deliveries. Fertilizer export inspections commenced around 15 October, expected into mid-2022. Argus assessed Middle East sulfur at $223-230 per tonne FOB on 28 October after the benchmark breached $200 earlier in the month. Brazil sulfur was assessed near $245-246 per tonne CFR, up more than $100 since the start of 2021. Chinese domestic solid climbed toward about Yn2,200 per tonne, the highest in roughly a decade, with December import CFR near $310, about Yn2,300 equivalent. Zhenjiang mainstream sulfur inventory fell to about 0.52 million tonnes at end-2021 from about 1.09 million at year-start. High CFR, high domestic, low port stock: three tightness prints into 2022 spring planting. Import dependence remained near 50 percent in the year's trade-press summary even as Argus expected Chinese production to rise almost 40 percent by 2025.

Alberta recovered sulfur still leaves mainly through the Vancouver stem. Vancouver's full-year 2,291,630 tonnes of sulphur, down 14 percent from 2.65 million in 2020, left Canadian marketers with unused inland forming and terminal capacity heading into 2022. The five-year ladder from this trough is 2.29, 2.79, 3.10, 3.35, then 3.51 million tonnes. Fourth-quarter 2021 is the trough year closing with a firming price. Alberta block and plant inventories remained the structural buffer: when Pacific netbacks failed to cover remelt, rail, forming, and terminal costs often cited above $150 per tonne in later Argus commentary, producers poured to block. Heartland's 30 June tank had more than doubled molten storage at the Industrial Heartland terminal. Sultran's more than 1,500 gondolas to Port Moody and North Vancouver is the rail backbone. Argus had noted several new Western Canada forming projects. Extra forming is a prerequisite for converting oil-sands sulfur into seaborne granules when FOB clears. By late 2021 the market was positioned for a much sharper 2022 spike if phosphate demand and logistics stress intensified together.

The Fertilizer Institute would later cite sulfur prices up 198 percent from March 2021 to March 2022 as a critical ammoniated-phosphate input cost. Fourth-quarter 2021 is inside that twelve-month window. USGS US elemental unit value about $92.30 per tonne for 2021, from $24.60 in 2020, is the annual average. 2022's $150 unit-value and $481 Tampa peak are the next step. CRU's conference call had expected prices to peak in first-quarter 2022. The call was early. April 2022's $481 is why. Kuwait's Al Zour complex was entering the sulfur market with operations expected in early 2022. Al Fadhili more than 1 million tonnes a year and Barzan about 800,000 tonnes a year, delayed by COVID into 2021, were the other Gulf increments. Incremental supply and tighter phosphate trade arrived in the same months. Price still rose. Demand-side policy beat supply-side tonnes in the fourth quarter.

USGS Canada about 4.9 million tonnes, world about 80 million, US about 8.1 million, and Canada about 73 percent of US elemental imports for 2017-20, frame Alberta and Vancouver as a structural North American swing source. Suncor's more than 800,000 tonnes a year marketable across oil sands, gas plants, and refineries is the operator slice. BC Insight's sour-gas decline and oil-sands offset is the geography inside the 4.9 million tonnes. Molten rail south into the 73 percent import share, and solid west into a 2.29 million tonne harbour, are the two doors. Fourth-quarter firmness paid the south door immediately. It paid the west door in 2022's 22 percent rebound.

Indonesia sulfur demand doubling by 2025 on HPAL, and US lithium acid extra 1.2 million tonnes a year by 2030, remained conference add-ons. Phosphate was still the organizer. IFA's later 2023 MAP and DAP still below 2020 would show how Chinese export policy and the 2022 quota delayed the phosphate volume recovery. December 2021 is the tightness that made 2022's first-half surge possible, not yet the quota that crashed it.

Alberta recovered sulfur still leaves mainly through the Vancouver stem. World tightness shows up there as unused forming headroom and a pad that can remelt when FOB covers the export stack. Closing 2021 with Tampa near $183 after an early-year print near $69 compressed a full mini-cycle into twelve months. The move validated USGS language about supply-driven firmness without yet matching the April 2022 extremes. Heading into 2022, phosphate restocking risk, residual refining tightness, and geopolitical shocks around energy trade were all latent. Licensed weekly assessment grids are not restated here. UNCERTAIN: precise year-end 2021 AER Alberta inventory tonnes. Industry commentary later placed multi-year lows only in 2025. The public data stack available to open researchers, USGS Tampa summaries, Port of Vancouver sulphur, and AER inventory products, already framed the market as one that could reprice quickly if demand and logistics stress arrived together. They did, in February and July 2022.

Key points

• USGS: Q4 2021 Tampa remained ~$183/lt after summer peak path.
• Vancouver 2021 sulphur 2.29 Mt set a low base before 2022-25 volume growth.
• Alberta stockpile economics: pour when export chain costs exceed FOB.
• Stage set for 2022 volatility as fuel demand and phosphate cycles overlapped.
• UNCERTAIN: end-2021 Alberta provincial stock versus May 2019 reference lows cited later.

30-day watchlist

• USGS 2022 Tampa open versus the $183/lt Q4 close and BC Insight's ~$83 early-2021 neighbourhood.
• January Vancouver loadings versus the 2.29 Mt 2021 trough.
• Chinese January import tonnes versus Zhenjiang's 0.52 Mt year-end stock.
• Al Zour early-2022 operations commentary versus the $223-230/t late-October Middle East FOB.
