Acrylonitrile Spot Prices Soften: Supply-Demand Dynamics and Industrial Transmission Behind Lihuayi's Price Cut

The acrylonitrile spot market has just flashed a signal worth noting. On July 8, 2026, Lihuayi Lijin Refining cut its spot offer by 100 yuan/ton to 9,100 yuan/ton ex-works, while its 260,000-ton/year acrylonitrile unit continues to run at full capacity. Although the reduction appears modest, it signals that supply-side pressure is transmitting to prices against a backdrop of overall chemical raw material weakness.

Background

Lihuayi Lijin is a key player in China's acrylonitrile capacity, with its 260,000-ton/year plant holding a significant market share. This price cut is not an isolated event but a microcosm of the shifting supply-demand balance. Industry data shows that in the first half of 2026, new capacities from Zhejiang Petrochemical Phase II and Sierbang Petrochemical came online, pushing total national capacity toward 3.5 million tons/year. Downstream demand growth, however, has not kept pace—especially in acrylic fiber and ABS resin sectors, where operating rates languish at 70%-75% due to weak end-user consumption.

This mismatch is reflected in inventory data. According to the China Chemical Information Center, social inventories of acrylonitrile in East China rose about 18% from the start of the year, hitting a two-year high. Lihuayi's price cut is essentially a proactive measure to reduce inventory pressure and test pricing strategies of other producers.

Industry Impact

For upstream propylene, the feedstock price is also weak, hovering around 6,800 yuan/ton in Shandong, offering limited cost support. This means acrylonitrile producers' profit margins are not severely squeezed by the price cut; instead, the move may stimulate downstream buying to alleviate inventory buildup.

For downstream sectors, this is a potential positive. Acrylic fiber yarn manufacturers, where acrylonitrile accounts for 60%-70% of raw material costs, stand to benefit directly. Lower acrylonitrile prices could improve the cost competitiveness of acrylic fiber against cotton and polyester. The ABS resin industry, acrylonitrile's second-largest consumer, will also see cost relief, as acrylonitrile makes up about 30% of ABS production costs, boosting margins for modified plastics firms.

In the carbon fiber segment—though small in volume but fast-growing—higher purity requirements make price elasticity lower. However, a sustained decline in acrylonitrile prices could reduce precursor costs, aiding long-term cost reduction and promotion of domestic carbon fiber.

Practical Recommendations

For Buyers - Recommend slowing spot purchases and observing whether other producers follow suit. Historical patterns suggest that after a major player adjusts prices, a new industry consensus typically forms within 1-2 weeks. - For long-term contract holders, try negotiating with suppliers to link July contract prices to spot levels, seeking more flexible pricing terms. - Monitor inventory safety margins: current prices are near 2025 levels (~9,000 yuan/ton). If prices break below 9,000 yuan/ton, downstream restocking may pick up, creating rebound risk.

For Export Firms - For exporters of acrylic yarn or ABS products, lower acrylonitrile costs enhance export competitiveness. If the yuan exchange rate is also favorable, consider increasing orders from Southeast Asia and the Middle East. - In pricing strategies, moderately reduce forward export quotes to capture market share, but retain price adjustment clauses to guard against raw material reversals. - Watch EU and US anti-dumping actions on Chinese chemicals: cost-driven export surges could trigger trade friction. Diversify export destinations to avoid over-reliance on single markets.
