The demand for downstream refrigerant R22 continues to be weak after the holiday, and the support for trichloromethane demand has weakened. In addition, the R22 quota will continue to decrease in 2025, which will have a negative impact on trichloromethane. In 2013, the baseline production quota for second-generation refrigerants in China was 426400 tons. After multiple pressure drops, it will be reduced to 163600 tons by 2025. Among them, the production quotas for R22, R142b, and R141b are 149100 tons, 0.34 tons, and 0.92 tons, respectively.

From September 1st to 29th, the domestic xylene market price fell from 5640 yuan/ton to 5480 yuan/ton, with a cumulative price drop of 2.84% during the period.

In the first half of the week, the toluene market fluctuated weakly, and the weakening of crude oil in the second half of the week dragged down market sentiment, causing market prices to continue to decline. The Shandong region has been dragged down by the crude oil market this week, resulting in an overall decline in prices. Negotiations in the East China region are quiet, and offers are generally low. Affected by loose supply, the enthusiasm for downstream market entry in southern China is weak, and the prices of main refineries have been lowered, resulting in an overall weak market atmosphere..
Late period: The domestic mixed xylene market first rose and then fell in this cycle. Among them, the inventory in Shandong region is low, and the prices of the main refineries have been adjusted slightly. Transactions in the region are more in line with demand. There is little change in inventory in the East China region, and prices have slightly increased. The market trading situation in South China is weak, downstream procurement is weak, and prices have slightly increased. As of the end of the month, with the end of pre holiday stocking and a decline in downstream purchasing intentions, the xylene market continued to decline due to a lack of demand support.
Cost wise: According to the Commodity Market Analysis System of Shengyi Society, as of September 26th, the settlement price of the November WTI crude oil futures contract in the United States was $65.72 per barrel. The settlement price of Brent crude oil futures for the December contract is $69.22 per barrel. During this round of price adjustment cycle, geopolitical factors remain one of the important factors affecting the crude oil market. The resurgence of geopolitical conflicts in the Middle East has triggered a rebound in the international crude oil stage, but OPEC+has decided to continue increasing production in October. In addition, with the increase in US oil inventories, the market still has high expectations of supply surplus pressure, resulting in weak momentum for international oil prices to rise.
