China Petroleum and Chemical Industry Federation portal Chemall published its September 11 domestic refinery sulfur reference table on Friday morning.
The table lists Dongming Petrochemical liquid sulfur at 8,000 yuan per tonne and solid sulfur at 8,500 yuan per tonne.
The 500 yuan solid premium over liquid reflects forming, degassing, and handling costs at Shandong coastal refineries that have been steady in open market accounts through early September.
Dongming's liquid quote sits roughly 289 yuan below Shengyishe's September 11 national benchmark at 8,289.25 yuan.
The solid quote at 8,500 yuan sits roughly 211 yuan above the same benchmark, illustrating the regional split between refinery gate and formed-product markets.
SMM's September 11 weekly review put Shandong EXW sulfur at 7,657 to 8,400 yuan with an average of 8,028.5 yuan, bracketing the Dongming liquid quote.
SunSirs' September 10 account described domestic refinery operations as steady with port inventories relatively low, even as Middle East import arrivals are slowed by Hormuz shipping risk.
September 10 SunSirs data put East China liquid sulfur at 7,535 yuan per tonne, up 40 yuan on the day, while solid sulfur in East China held at 7,700 yuan.
Dongming's September 11 liquid quote at 8,000 yuan is above the SunSirs East China liquid print, consistent with refinery-specific pricing rather than a regional average.
For Pacific import economics, domestic refinery gate prices near 8,000 yuan set a floor for landed Middle East tonnes even when the national benchmark oscillates.
Alberta formed sulfur on the Vancouver stem competes into the same Chinese buyer set that watches both refinery gate and port granular quotes.
Desk read: refinery tables are granular but they anchor the domestic cost floor. When Shandong liquid holds at 8,000 yuan, Pacific exporters have room to negotiate even as the national index corrects.
