Report Information - Report Title: C3 Industry Chain Weekly Report [1] - Report Date: October 19, 2025 [1] - Analyst: Chen Xinchao, Zhao Shucen [1] Report Industry Investment Rating - No industry investment rating was provided in the report. Core Views LPG - This week, LPG's civil price declined due to international oil prices and a loose domestic supply - demand pattern; import costs dropped as FEI and CP decreased. The contract rebounded from previous lows. In the short - term, chemical demand is weak, and supply is affected by macro and policy uncertainties. Attention should be paid to macro factors, import costs, and international geopolitical situations [3]. Propylene - This week, domestic propylene prices declined due to changes in supply and demand. Supply decreased slightly, and demand weakened significantly. Next week, supply is expected to increase slightly, and demand will improve, but the loose pattern will continue. Propylene prices are expected to remain weak with limited downside [4]. Summary by Directory LPG - Price & Spread - LPG domestic spot prices, including those of civil gas and other types, generally declined this week. Import gas prices also showed a downward trend, and the basis of various types of LPG changed significantly [7]. - The US - Far East freight dropped sharply, and the spreads between FEI and CP showed opposite trends. Propane prices weakened significantly [14][23]. LPG - Supply - US propane shipments to Japan and South Korea increased significantly due to the substitution of cracking raw materials. Canadian propane shipments decreased slightly. Qatar, UAE, Kuwait, and other Middle Eastern countries' LPG shipments showed different trends. China's LPG imports decreased, and the total LPG commodity volume increased slightly [32][40][59]. - The total domestic LPG commodity volume was 55.0 tons (+1.3%), with civil gas at 22.2 tons (+1.8%). Propane imports decreased by 12.9 tons [62][71]. LPG - Demand & Inventory - The开工 rates of PDH and MTBE decreased slightly. In terms of inventory, LPG refinery and port inventories were at a high level year - on - year and mainly decreased month - on - month (except in Shandong) [77][86][96]. Propylene - Price & Spread - Upstream prices of the propylene industry chain generally declined, and propylene prices also decreased. The prices of downstream products in the propylene industry chain showed different trends, and the profits of some products changed significantly [107][109]. - International and domestic propylene prices both showed a downward trend, with international prices having a slight correction from high levels and domestic prices running weakly [110][118]. Propylene - Balance Sheet - The开工 rates of the propylene industry chain changed this week, with some devices having decreased开工 rates. The supply and demand of propylene in the national balance sheet showed different trends in different months, and the inventory decreased slightly [128][130][131].

Report Industry Investment Rating - Not provided in the content Core Viewpoints - **LPG**: Short - term weak operation. Although PDH profit has improved significantly due to the weakening of propane, the current tense Sino - US trade relationship and strong market wait - and - see sentiment make it difficult to fully realize demand support. However, considering that the PG main contract has reached a new low and civil demand is gradually improving, the downward space is expected to be limited [3]. - **Propylene**: Demand is weakening, and it will run weakly in the short term. Next week, although the supply may shrink due to the expected maintenance of PDH devices, the demand will weaken as some PO and acrylic acid devices plan to stop for maintenance, so the upward momentum of prices is limited [4].
