Shengyishe reported September 20 that Shandong Lihuayi Chemical kept sulfur units operating normally while cutting both industrial solid sulfur and liquid sulfur offers.
Each grade fell 400 yuan per metric tonne to 7,600 yuan in the open plant quote, a single-step move larger than Shengyishe's flat granular spot print at 7,669 yuan in the afternoon commodity table.
PriceSeek commentary bundled with the release scored the adjustment as mildly bearish, citing stable supply and explicit intent to move inventory at lower levels.
The cut lands inside Longzhong's September 20 Shandong liquid sulfur band of 7,600 to 7,625 yuan per tonne, down 205 to 345 yuan week on week in the same wire.
Northwest solid sulfur at 7,250 to 8,000 yuan in Longzhong's account shows wider regional dispersion than a single Shandong petrochemical quote, but the direction is the same.
Zhenjiang port granular at 7,200 yuan, down 500 yuan week on week in Longzhong, sits below Lihuayi's 7,600 yuan Shandong print, highlighting coastal versus inland spreads.
SMM's September 18 weekly review put Shandong elemental sulphur EXW averaging 7,453.5 yuan, down 7.2 percent week on week, a benchmark-level move that preceded this plant-specific cut.
Shengyishe's September 20 trend analysis labeled a strong rebound on improved five-day and ten-day spreads even as the twenty-day spread widened to negative 226.51 yuan.
Technical labels and plant quotes can diverge on weekends when benchmark sessions are thin; desks should prioritize executable Shandong and port levels over oscillation tags alone.
Middle East FOB sulphur averaged 855 dollars per tonne flat in SMM's 18 September table while CFR India was cut to an average near 1,050 dollars per tonne from 1,075 dollars.
For Alberta forming plants, weaker Shandong liquid offers do not automatically translate into lower Vancouver FOB when BC Insight holds a 1,100 to 1,200 dollar band on confirmed Pacific sales.
SMM's August customs tables list Canada among China's sulfur import origins, keeping Pacific swing tonnes in the import mix even as domestic plant quotes fall.
Alberta provincial sulfur stocks at 11.66 million tonnes in July 2025 remain the inventory cushion when Chinese spot weakens faster than seaborne offer levels.
Desk read: Lihuayi at 7,600 yuan is a concrete Shandong liquid print for September 20. Pair it with Zhenjiang at 7,200 yuan and a flat 7,669 yuan spot line to read domestic dispersion, not a single national price.
