Alberta and Vancouver export desks closed October with the Chinese domestic sulfur benchmark frozen on the lows, as Shengyishe's 100ppi rawmex page at 16:00 on 31 October left the national print at 5,344.25 yuan per metric tonne, unchanged on the day after the 207.5 yuan collapse on 30 October.
The open methodology header marked 5,344.25 yuan as both the session benchmark and the three-month low, against a three-month peak of 9,535.67 yuan and a three-month average of 7,959.22 yuan, signalling that phosphate-led replacement cost has stopped falling without yet rebounding.
SunSirs' English commodity table listed industrial granular sulfur at 5,344.25 yuan per tonne on 31 October, identical to 30 October, giving Pacific desks a second open feed confirming the flat close.
The 100ppi afternoon spot comparison table had already rolled granular sulfur from 5,551.75 yuan to 5,344.25 yuan on 30 October at minus 3.88 percent; Friday's zero change therefore extends the unwind rather than adding a fresh cut into November nomination week.
Monitored coastal elemental sulfur on the 100ppi wire remained 1.1251 million tonnes as of 28 October, with Fangchenggang at 420 thousand tonnes, Zhanjiang at 350 thousand tonnes, Zhenjiang at 218 thousand tonnes, Dafeng at 82 thousand tonnes, Beihai at 18 thousand tonnes, and Nanjing at 10 thousand tonnes in the last published breakdown, unchanged since the prior inventory release.
Shandong refinery list prices on the wire still showed Dongming liquid sulfur at 5,400 yuan per tonne and solid sulfur at 6,300 yuan per tonne following 30 October cuts, with Li Huayi liquid and industrial sulfur at 5,370 yuan per tonne on the same feed, keeping domestic plant offers above the national benchmark.
Middle East nomination math was unchanged on the open record: Shanghai Metals Market's 8 October flash still lists October 2026 producer contracts at QatarEnergy 835 dollars per tonne FOB, Kuwait Petroleum Corporation 820 dollars FOB, and ADNOC 890 dollars FOB Ruwais, with November QSP, KSP, ADNOC OSP, and Saudi Aramco monthly postings still absent on verified open wires at desk time.
ChemPriceHub's mid-October international roundup still frames seaborne competition near 830 to 840 dollars FOB Vancouver and 740 to 790 dollars FOB Middle East ex-Iran for the week of 15 October, the dollar bands Alberta blocks must clear when yuan replacement cost sits on a three-month floor.
Alberta Energy Regulator ST3 sulphur statistical files on the public index were unchanged at desk time, with the verified_public August 2026 provincial closing inventory still the North American stockpile anchor behind rail and terminal scheduling.
Port of Vancouver and Statistics Canada HS 2503 tables showed no new open monthly sulfur line on this sweep; VFPA cargo pages returned errors on automated fetch.
USGS Mineral Industry Surveys sulfur links for 2026 remain available through July on the national minerals page; no additional U.S. monthly was added to site JSON on this run.
