Shandong Dongming Petrochemical Group cut sulfur list prices sharply on Monday 19 October, reopening the Chinese domestic slide after two sessions held at the Shengyishe rawmex floor.
Shengyishe PriceSeek reported liquid sulfur down 1,100 yuan per metric tonne to 5,000 yuan per tonne and solid sulfur down 800 yuan per tonne to 6,500 yuan per tonne on 2026-10-19.
The wire describes Dongming as a regional core refinery, so the move can drag Shandong plant postings and spot confidence after domestic screens had paused at 6,652.33 yuan on 17 and 18 October.
Tonghuashun iFind data on the same day put national sulfur spot at 6,076.75 yuan per tonne, down 575.58 yuan day on day, a faster tape than the prior weekend hold.
Shengyishe's morning 基准价 article still printed 6,652.33 yuan per tonne on 19 October, down 13.45 percent versus the 7,685.67 yuan month-start reference in the statistics table.
The gap between the 基准 line and the iFind spot print is a reminder that Chinese sulfur trades on plant lists, port inventory, and screen aggregates that do not always move in one tick.
For Alberta exporters the Pacific bid still comes from open Vancouver FOB context. ChemPriceHub's 15 October roundup cited transactions at 830 to 840 dollars per tonne FOB, down 50 dollars on the week.
ChemPortal's open 15 October sulphur page carried Vancouver loading to China on 50 to 60 thousand tonne parcels at 38 to 43 dollars per tonne, the freight band desks net against domestic yuan replacement cost.
October Middle East producer contracts on Shanghai Metals Market's notice read QatarEnergy at 835 dollars per tonne FOB, Kuwait Petroleum Corporation at 820 dollars, and ADNOC at 890 dollars FOB Ruwais.
Alberta Energy Regulator ST3 through August 2026 shows closing sulfur inventory at 11,042,851.4 tonnes with August production at 328,937.3 tonnes, the verified_public stock anchor behind the Vancouver stem.
Coastal elemental sulfur inventories near 1.123 million tonnes on Shengyishe's mid-October port wires give import buyers cover while domestic offers fall, a combination that can delay fresh stem enquiries.
Desk read: treat the Dongming cut as a Shandong-led step lower into a spot screen already printing sub-6,100 yuan on 10jqka; size Vancouver netbacks with the 830 to 840 dollar FOB band plus 38 to 43 dollar freight rather than a licensed weekly assessment grid.
