I. Market Trend Review

In April 2026, the domestic PA66 market generally exhibited a trend of surging to a high point followed by a slight pullback. The core driving logic shifted gradually from strong cost support at the beginning of the month to a dynamic interplay between costs and supply-demand fundamentals by the end of the month. The SunSirs PA66 benchmark price started at 20,866.67 RMB/ton on April 1st; driven by rising costs, it accelerated its ascent, climbing to 25,100 RMB/ton on April 14th—marking a one-year high—with a cumulative monthly increase that briefly exceeded 20%. Subsequently, the market entered a phase of high-level fluctuation and slight retreat. As of April 28th, the benchmark price stood at 23,500 RMB/ton, representing a 12.62% increase from the beginning of the month, though it had corrected downward from the mid-month peak.

II. Analysis of Influencing Factors

Cost Aspects: From the beginning to the middle of the month, the high-level consolidation of raw material prices served as the primary driver behind the rise in PA66 prices. Regarding hexamethylenediamine (HMDA), Invista raised its April contract price to 26,000 RMB/ton—a significant increase from the start of the year—while domestic quotes also remained at a high range of 22,000–23,000 RMB/ton. Although adipic acid prices experienced a slight dip in mid-April, they generally remained at historically high levels. The high-level fluctuation of international oil prices in the preceding period, along with the energy premium resulting from geopolitical conflicts, had become deeply embedded within the industrial chain, thereby constituting strong cost support. Entering the latter part of the month, spot prices for certain raw materials—such as adipic acid—showed signs of decline, causing the strength of cost support to weaken somewhat.

Supply Aspects: Throughout April, the circulation of spot goods in the market remained consistently tight. With a reduction in imported supplies, overall inventory levels held by manufacturers and traders remained low, while the operating rates of some enterprises hovered around 70%–80%. Traders exhibited a strong reluctance to sell, a sentiment that provided underlying support for prices.

Demand: Downstream sectors—such as the textile industry—have demonstrated low tolerance for current high price levels. Consequently, they have generally adopted a strategy of placing "small, strictly need-based orders" and purchasing on an "as-needed" basis. Large-scale procurement orders remain scarce, and overall trading activity lacks vigor, resulting in a stalemate characterized by "supplier control over the market" juxtaposed with "suppressed demand." This persistent weakness in demand continues to constrain any potential for further price appreciation.

III. Short-Term Market Outlook

Looking ahead, the PA66 market is expected to maintain a pattern of high-level volatility in the short term; significant unidirectional price movements are unlikely to materialize. Key factors to monitor include fluctuations in raw material prices, the progress of new production capacity coming online, and the pace of recovery in downstream demand. Should raw material prices retreat or demand remain persistently weak, prices may experience a slight downward correction; conversely, if raw material costs remain elevated or demand stages an unexpected recovery, prices are likely to see a modest rebound.
