1. Today's Summary
①、中oil South PP price adjustment: Dyed yarn, film base material and fiber down 50%, extruded down 50-100%, block copolymer down 50-80%, pipe material up 50%; Sinopec East PP up 50%, Yang K8003 set at 7800, 1215C set at 7850, Zhen M60T set at 7650, M09 set at 7750, M30RH set at 7800.
Today, the domestic polypropylene price has increased by 1.42% to 17.93% compared to yesterday, mainly due to the shutdown maintenance of Yulong Petrochemical's five lines (300,000 tons/year) PP unit and Beihai Refining's (200,000 tons/year) PP unit. The daily production of fiber has decreased by 2.74% to 25.28% compared to yesterday, while the daily production of low melt copolymer has decreased by 0.66% to 10.35%.
③ This week (20250307-0314), the supply-demand gap narrowed significantly to 40,000 tons mainly due to a considerable decline in supply caused by more equipment maintenance, combined with demand still slowly recovering, leading to an improvement in the supply-demand gap.
2. Spot Overview

The spot price of polyester lycra in East China is up 1 yuan per ton as expected.
Today's futures showed a narrow rebound, with the morning market's reported prices increasing by 10-30 yuan per ton. Merchants in the spot market attempted to follow the price increase,试探跟涨. Higher crude oil prices provided solid cost support, but demand remained largely unchanged. Downstream buyers continued to purchase based on essential needs, and trading within the market was cautious. By midday, the mainstream price of拉丝 in East China was between 7280-7430 yuan per ton.
3、Price Forecasting
The impact of overseas tariffs on export orders and weaker-than-expected terminal demand are suppressing market gains. While the impact of newly commissioned plants is limited, the recent increase in polypropylene plant maintenance has led to a decrease in daily production, easing pressure from the supply side. Costs provide a floor for prices. It is expected that the short-term polypropylene market will trade within the 7280-7450 yuan/ton range, with a focus on the recovery of demand and changes in crude oil prices.

This week, the PC factory output remains generally stable, with some prices adjusted downward.
2Spot Goods Overview

Today, the domestic PC market in China is experiencing narrow sorting at low levels. As of the afternoon closing, the reference price for low-end plastic grade resins in eastern China is mainly negotiated at 12,000-15,300 yuan/ton, while mid-high end resins are negotiated at 15,200-16,400 yuan/ton, roughly stable compared to yesterday. This week, the latest quoted prices for domestic PC factories are mostly steady, with some reducing prices by 150 yuan/ton, and Zhejiang Petrochemical's third round of auctions settled at a decrease of 100 yuan/ton compared to last week. In the spot market, both eastern and southern China are mainly characterized by low and weak sorting, with a slight supportive market sentiment due to expectations of supply reduction as the domestic PC equipment maintenance season approaches in April. Dealers' general attitude is to maintain steady prices, with limited inquiries and purchases from downstream buyers, resulting in a situation where there is little demand despite having a price.
3、Price Prediction
Affected by the partial PC factory equipment maintenance message in April, combined with the current historic low PC prices, the market overall atmosphere is heavily focused on stabilization and consolidation. However, considering the downstream demand has not shown any significant improvement, and the industry inventory needs to be dispatched, the expectation is for the domestic PC market to mainly exhibit a low-end weak consolidation and correction trend, pay attention to further market transaction developments.

PMMA:
1. Today's Summary
① The factory's price has stabilized.
②, Today, the domestic PMMA particle utilization rate is 64%.
2Spot Overview

Taking East China as the benchmark, today's PMMA particle closing price was 16,800 yuan/ton, unchanged from yesterday and below early expectations. Today's PMMA particle market saw limited fluctuations, with sellers' quotes showing no significant changes, mainly focusing on transactions.

Table 1 Summary of Domestic Polyamide 6 Prices (Unit: Yuan per Ton)

The PA6 chip market saw a slight increase today. The raw material caprolactam market edged up, increasing chip costs. Additionally, polymerization enterprises' willingness to offer discounts decreased, leading some to slightly raise their chip ex-factory prices. The availability of low-priced chips in the market decreased, and the atmosphere for downstream buyers to replenish at lower prices improved. The market transaction atmosphere was acceptable. In East China, PA6 standard spinning grade was priced at 10,400-10,600 yuan/ton, cash short delivery; high-speed spinning spot prices were 11,100-11,700 yuan/ton, acceptance bill included delivery. Chaohu prices were 9,700-9,800 yuan/ton, cash, self-pickup.
3、forecast
From a cost perspective, the caprolactam raw material market is likely to continue consolidating, while current losses in chip production and persistent cost pressures warrant attention to subsequent maintenance and capacity reduction by upstream raw material producers. In terms of supply and demand, polymerization enterprises generally maintain an operating rate above 80%, keeping production at high levels. Low-price purchases by downstream buyers are driving market transactions, and polymerization enterprises may have a mindset to stop losses, potentially leading to slight increases in chip ex-factory prices. It is expected that the polyamide 6 market will see a slightly positive trend recently, with close attention to be paid to downstream demand and price adjustments by manufacturers.
PA66:
