①, Sinopec Southwest PP price adjustment: Raffia, film and fiber down 50, injection molding down 50-100, copolymer down 50-80, pipe up 50; Sinopec East China PP up 50, Yangzi K8003 fixed at 7800, 1215C fixed at 7850, Zhenhai M60T fixed at 7650, M09 fixed at 7750, M30RH fixed at 7800.

② As of today, the domestic polypropylene shutdowns have increased by 1.42% to 17.93% compared to yesterday, primarily due to the shutdown and maintenance of Yulong Petrochemical's Line Five (300,000 tons/year) PP plant and Beihai Refining and Chemical's (200,000 tons/year) PP plant. The daily production percentage of pull lines has decreased by 2.74% to 25.28% compared to yesterday, while the daily production percentage of low melt index copolymers has decreased by 0.66% to 10.35%.

③, This week (20250307-0314), the supply-demand gap narrowed significantly to 40,000 tons, primarily due to a noticeable decrease in supply caused by increased plant maintenance. This, coupled with a slow recovery in demand, led to an improvement in the supply-demand balance.

2. Present Situation

Today, polypropylene filaments in the East China region closed at 7352 RMB/ton, up 1 RMB/ton from yesterday, meeting early expectations.

Today, the futures narrowly rebounded, with the market center shifting upward by 10-30 yuan per ton in the morning. Wholesale market traders tested following the涨势, with crude oil rising as cost support remained solid. However, demand showed no significant change, with downstream continuing to make just-in-time purchases. Trading remained cautious in the pit, with the mainmainline in the Hu東 area for rayon yarn closing between 7280-7430 yuan per ton by midday.

3, Basis between futures and spot

The price difference of ethylene in the Yangtze River Delta region is 26 yuan per ton, down 24 yuan per ton from yesterday. In the Beijing region, the price difference is -41 yuan per ton, down 23 yuan per ton.

4. Price Forecasting

Here is the translation: Exports impose tariffs on imported goods, reducing export orders, which in turn leads to a decrease in terminal demand and a decrease in the market's upward momentum, but new production capacity is limited, leading to lower production and a slower increase in supply, and is expected to support prices in the short-term market around 7280-7450 USD/ton.
