Acrylonitrile prices broke through the psychological threshold of 10,000 yuan per ton in mid-July. On July 17, the market reference price stood at 9,600 yuan per ton, down 4.79% from 10,083.33 yuan per ton on July 1. While the decline appears modest, for a supply chain heavily reliant on cost-based pricing, the signal is unmistakable.
Price Trend and Cost Logic
Acrylonitrile is a key raw material for acrylic fiber, ABS resin, acrylamide, and carbon fiber precursors. Its price fluctuations ripple through multiple pathways into the textile and chemical fiber sectors. Industry data shows this downturn is not isolated: the benchmark price dropped to 9,416.67 yuan per ton on July 15, before rebounding slightly to 9,566.67 yuan per ton, but the overall trend remains downward.
What does this mean? For acrylic fiber producers, raw materials account for over 60% of total production costs. A 400-yuan drop per ton of acrylonitrile reduces direct material costs by approximately 250 yuan per ton of acrylic fiber. However, unless downstream demand recovers simultaneously, this cost saving is unlikely to translate into profit and will instead be absorbed by end-market price pressure.
Upstream-Downstream Transmission and Regional Responses
Major acrylonitrile production capacity is concentrated in Shandong, Jiangsu, and Zhejiang—regions that are also core hubs for chemical fiber clusters. In Zhejiang, for instance, acrylic yarn mills in Shaoxing and Xiaoshan have adjusted procurement strategies: shifting from replenishing inventory as needed in early July to a wait-and-see approach, with some compressing raw material inventory cycles from 15 days to 7 days.
This destocking behavior creates a negative feedback loop in the supply chain: slower downstream procurement forces upstream producers to cut prices, further weakening price expectations. A similar pattern is emerging in the ABS resin sector, where several modified plastics plants in East China suspended large-volume order locking in the second week of July, awaiting clearer bottom signals.
Practical Implications for Buyers and Exporters
In the short term, acrylonitrile prices still have room to decline. International crude oil is hovering around $75 per barrel, providing weak cost support for propylene, while domestic acrylonitrile operating rates remain above 80%, with no significant supply-side tightening. For buyers, the period from late July to early August may present a relatively favorable entry point.
For exporters, the situation is more complex. Overseas acrylic fiber orders are typically priced quarterly, and rapid raw material price drops could create exchange rate and cost inversion risks for existing contracts. Companies targeting Southeast Asian and South American markets, where clients are highly price-sensitive, may face order losses if domestic price adjustments lag.
