COVID soft market and early refinery recovery into spring 2021

Elemental sulfur entered 2021 still marked by the 2020 pandemic shock to refining and fuel demand. Recovered sulfur output tracks oil and gas processing, so lower throughputs had constrained North American and global availability through late 2020 even as phosphate demand began to firm. USGS Mineral Commodity Summaries later recorded that Tampa, Florida molten contract prices began 2021 near about $69 per long ton, then moved higher as supply issues and demand recovery interacted. Port of Vancouver fertilizer-category sulphur throughput for full-year 2021 settled at 2.29 million tonnes, down from 2.65 million tonnes in 2020, consistent with a soft export year despite rising inland prices later in 2021. Canadian oil sands and sour-gas recovery continued to produce byproduct sulfur that could be formed for Pacific export or poured to block when netbacks were weak. UNCERTAIN: exact Alberta Energy Regulator provincial closing stock for Q1 2021 is not restated here from a single open secondary source; treat inventory as elevated relative to later 2025 lows but verify against AER Sulphur Balance tables. Market participants entering spring 2021 still carried balance-sheet scars from 2020, when fuel demand destruction cut refinery runs and, with them, recovered sulfur availability in the Atlantic Basin. Phosphate producers that had delayed purchases faced a thinner spot offer list even while absolute prices remained modest by later-cycle standards. Canadian marketers balanced molten rail commitments into the United States against solid forming for Pacific stems, knowing that Vancouver’s weaker 2021 annual total would later mark the trough of the decade’s volume path. Public statistics from the Port of Vancouver remain the cleanest open measure of that trough. USGS commentary that high 2021 prices reflected supply issues rather than a permanent demand boom is consistent with a market still healing from pandemic throughput cuts. For Alberta producers, the early-year calculus stayed familiar: if export netbacks after remelt, rail, forming, and terminal charges did not clear, block pouring preserved optionality for a firmer later window.

Key points

• USGS MCS: Tampa molten contracts began 2021 near ~$69/lt before rising later in the year.
• Port of Vancouver sulphur: 2.29 Mt in 2021 vs 2.65 Mt in 2020 (port statistics).
• Recovered sulfur supply remained tied to refining and oil sands rates, not sulfur price signals.
• Pacific export chain (remelt, rail, form, terminal) remained costly relative to soft FOB realizations early in the year.
• UNCERTAIN: Q1 2021 AER Alberta inventory print pending direct AER table pull.
