Alberta and Pacific export desks entered the 12 November session with China's national sulfur benchmark unchanged for a third calendar day, a pause that leaves the open domestic print more than 50 percent below the mid-June 2026 cyclical high while Gulf nomination math still runs on November Qatar and Kuwait contract cuts.
Shengyishe's 100ppi morning benchmark notice at 08:30 on 12 November carried 5,151.75 yuan per metric tonne, unchanged day on day at 0.00 percent and down 3.6 percent from the 5,344.25 yuan November open on the same header.
The annual statistics block on that 100ppi page for the window from 12 November 2025 through 12 November 2026 listed a maximum of 11,084.33 yuan per tonne and a minimum of 3,541.00 yuan, with the session print sitting in the wire's one-year mid-low band.
ChemNet on 12 November relayed 100ppi monitored data showing Yangtze River port imported granular sulfur at 5,000 to 5,100 yuan per tonne and Shandong refinery liquid sulfur at 5,250 to 5,400 yuan per tonne, with both bands described as roughly 55 percent below the June highs.
ChemNet paired those spot bands with the same 5,151.75 yuan benchmark on 11 November that the 12 November 100ppi notice confirmed, framing a market where the national header is flat even as port-level replacement costs sit in a tight yuan corridor.
Longzhong, republished through Sina Finance on 12 November, summarized 2026 China port spot with a year low at 4,050 yuan per tonne in late February and a year high at 11,750 yuan in early and mid June, attributing the mid-year spike to sustained Middle East geopolitical stress on seaborne supply.
The same Longzhong article put Middle East sulfur shipments to China down 70.55 percent year on year through September, citing Hormuz disruption early in the year and softer Chinese buying when dollar cargoes stayed expensive against weak phosphate margins.
Longzhong's forward paragraph, labeled as industry analysis on the open wire, expects 2027 Chinese sulfur prices to trend lower inside a volatile range, with the year's high likely in mid to late first quarter 2027 and the low in the fourth quarter of 2027, and it flags a possible domestic sulfur futures listing as a structural market change.
Sulfur Wire restates that seasonal language on the dedicated sulfur price outlook 2027 topic with source links; Alberta desks still translate the yuan unwind into Vancouver stem timing rather than treating the Longzhong shape as a Sulfur Wire price target.
ChemPriceHub's international roundup published 6 November for the 5 November market remains the last verified open partial for November Gulf nominations, with QatarEnergy QSP at 735 dollars per tonne FOB Ras Laffan and Mesaieed and Kuwait Petroleum Corporation KSP at 720 dollars FOB, each down 100 dollars from October.
The same ChemPriceHub piece said Abu Dhabi National Oil Company was expected to release its November OSP quote by the end of that week, and no fresh November dollar OSP for Ruwais had appeared on the open English pass at desk time on 12 November.
Saudi Aramco's monthly sulfur posting likewise carried no new November contract dollar level on the ChemPriceHub 5 November read, so October's ADNOC 890 dollars FOB Ruwais row remains the last fully sourced UAE marker in prices-latest.json until a dated November print lands.
For machine-readable China rows, china-benchmark-daily.json adds a 12 November verified_public stamp at 5,151.75 yuan with the 100ppi morning benchmark URL; prices-latest.json updates SR-CN-BENCH-100PPI to the same date and level.
Licensed Argus, CRU, and ICIS weekly assessment grids stay with their publishers; Sulfur Wire restates only figures already on open wires with URLs.
Desk read: treat 5,151.75 yuan as the 12 November spot and benchmark reference, run nomination math with November QSP 735 dollars and KSP 720 dollars, and watch ADNOC November on open English wires while Longzhong's 2027 seasonal language stays cited on sulfur price outlook 2027.
