1、 Price trend

According to the monitoring of the Commodity Market Analysis System of Shengyi Society, the futures market has generally declined due to the impact of US tariff policies. This week (4.7-11), the PVC spot market price followed suit and performed weakly. As of Friday, the average price of SG-5 PVC carbide method in China was 4808 yuan/ton, with a price drop of 1.84% during the week.
2、 Market analysis
This week, PVC prices first fell and then rose. At the beginning of the week, due to the negative impact of US tariff policies, the stock and futures markets generally declined. The PVC futures market fell significantly, and the spot market was also suppressed. The market generally fell by around 100 yuan/ton. On the one hand, the lack of favorable fundamentals has led to a sharp drop in crude oil prices and a downturn in the futures market. On the other hand, in terms of supply and demand fundamentals, the spot PVC market has shown loose supply and demand, and most manufacturers are operating stably. The supply pressure has not changed much, dealers’ offers are generally weak, downstream demand performance is insufficient, downstream procurement is mainly based on spot prices, inquiry and procurement enthusiasm is not high, and the market atmosphere is sluggish. The hanging order price is relatively low. Overall, it is still mainly driven by basic needs, and the trading atmosphere is average. On Friday, the market oversold the range, and due to the rebound of the stock and futures markets, PVC spot also rebounded, but did not break through the previous decline. As of now, the quotation range for PVC SG5 electrical aggregate in China is mostly around 4750-4850 yuan/ton.
In terms of upstream calcium carbide, since April, the market price of calcium carbide has stabilized and risen. This week, the price increase was weak, and the price has stabilized. According to the commodity analysis system of Shengyi Society, the price fluctuation this week was 0. But the overall increase in April exceeded 5%, providing some cost support for PVC. It also restricts the downward space of PVC.
3、 Future forecast
The PVC analyst from Shengyi Society believes that the supply and demand performance of the PVC spot market is stable. Although it is affected by fluctuations in the international economic environment in the short term, in the medium term, the market will gradually return to fundamentals. It is expected that PVC prices will continue to maintain a range adjustment pattern next week.

According to the Commodity Market Analysis System of Shengyi Society, the mixed xylene market has fluctuated upward this week. From March 31 to April 7, 2025, the price of mixed xylene has increased from 6340 yuan/ton to 6420 yuan/ton, an increase of 1.26%. As the holiday season approaches, downstream purchasing intentions are still acceptable, and companies actively enter the market for inquiries. The market trading situation is good, and refineries in Shandong generally operate with low inventory levels. The supply in East China is relatively loose, leading to a decline in market disinfection. The price increase of Sinopec in the South China region has driven the spot market prices to strengthen, but the market trading is weak, and downstream demand is increasing.

Cost wise: International crude oil futures plummeted on April 4th. The settlement price of the main contract for WTI crude oil futures in the United States was $61.99 per barrel, a decrease of $4.96 or 7.4%. The settlement price of the main Brent crude oil futures contract was $65.58 per barrel, a decrease of $4.56 or 6.5%. Affected by US tariff policies, oil prices have plummeted for two consecutive trading days, with WTI experiencing a cumulative drop of nearly $10. Investors are concerned about the risk of economic recession caused by the escalation of global trade conflicts. According to crude oil analysts from Shengyi Society, based on the subsequent impact of current US tariff policies, crude oil may enter a new cycle in the long term. The supply-demand balance may be disrupted and enter the process of rebalancing again. In the short term, given that countries are attempting to negotiate lower tariffs or impose retaliatory tariffs, tariffs may change and oil prices may fluctuate significantly in the short term.
Supply side:
Sinopec’s xylene quotation summary shows that the company is currently operating normally, with stable production and sales. The company’s quotation remains unchanged from the previous day. As of April 7th, East China Company quoted 6400 yuan/ton, North China Company quoted 6200-6300 yuan/ton, South China Company quoted 6550-6600 yuan/ton, and Central China Company quoted 6150-6350 yuan/ton.
Demand side:

This price is implemented in East China, North China, Central China, and South China. Yangzi Petrochemical, Zhenhai Petrochemical and other units are operating stably and selling normally, with a price reduction of 400 yuan/ton compared to March 28th. As of April 4th, the closing prices of the xylene market in Asia were $778-780 per ton FOB Korea and $803-805 per ton CFR China.
Market forecast: Affected by the news of US tariffs, the overall commodity market will weaken, crude oil prices will significantly decline, and the atmosphere in the spot market will be weak. The sales situation in Shandong region is good, and inventory is running at a low level. As the market atmosphere weakens, downstream wait-and-see sentiment is strong, and the demand side is bearish. Overall, the market atmosphere is relatively weak, with factory quotes generally decreasing this week. Downstream purchases are mostly on the wait-and-see side, with limited price support. It is expected that the market will operate weakly in the short term.

This week, the epoxy chloropropane market maintained stable operation. According to the monitoring and analysis system of Shengyi Society, as of March 26th, the benchmark price of Shengyi Society’s epichlorohydrin was 8850 yuan/ton, a decrease of -5.6% compared to the beginning of this month.

Price influencing factors:

Raw material side: The propylene market is showing a downward trend due to changes in supply and demand. According to the market analysis system of Shengyi Society, as of March 25th, the benchmark price of propylene in Shengyi Society was 6795.75 yuan/ton, a decrease of -0.26% compared to the beginning of this month (6813.25 yuan/ton). The glycerol market has experienced a narrow correction in price due to external and domestic demand, with a price drop of 1.94% compared to the end of last month.

Downstream demand side: The downstream epoxy resin industry has weak demand, and the overall market is mainly declining. The domestic epoxy resin market has a production capacity utilization rate of over 50%, and the supply remains normal. The decline in raw material prices, weak terminal demand, and the impact of individual plant shutdowns and production cuts have significantly suppressed the mentality of traders. The lack of active procurement has created negative constraints on the epoxy chloropropane market.

Market forecast: Business Society’s epoxy chloropropane analyst believes that the raw material side is declining and the cost support is insufficient. Part of the production enterprises on the supply side have shut down for maintenance, and coupled with weak downstream demand, traders’ purchasing mentality is not positive. It is predicted that the epoxy chloropropane market will continue to show a weak trend in the later stage, and more attention still needs to be paid to changes in market supply and demand.
