[Introduction]: Recently, offers from major manufacturers in East China for refrigerant R507A, both for domestic and foreign trade, have been rising. Social inventory in the secondary market remains low, with just-in-time procurement and limited earlier stockpiling. As of press time, the offer reference from major East China manufacturers is 54,000 yuan/ton (coordinated offers for domestic and foreign trade), up 2.86% month-on-month. The mainstream offer in the East China market ranges from 52,000 to 54,000 yuan/ton.

This round of price increases for fluorinated refrigerant R507A is mainly driven by fluorinated refrigerant R143a. The price rise of R143a is primarily due to a series of production cuts and reduced loads by major plants lasting about 1.5 months starting in April, leading to supply contraction and price hikes.

Additionally, strong support from blended fluorinated refrigerants, combined with the approaching summer peak season and plant shutdowns or load reductions upstream, has limited supply. Moreover, the earlier substantial shipment volumes of blended refrigerants R507A/404A prompted major manufacturers and filling plants to control and adjust offers upward from January to May 2026. The market price of blended refrigerant R507A has risen since January (up 8,000 yuan/ton) and currently holds at a high level of 53,000 yuan/ton.

Under multiple factors, the pricing of anhydrous hydrogen fluoride rose by about 2,300 yuan/ton from March to April, providing strong cost support for fluorinated refrigerant R143a. As the profit chain passes downstream, R143a's price fluctuations allow greater room for upward adjustment.

Considering supply-demand fundamentals, cost support, and market sentiment, the short-term price trend for fluorinated refrigerant R143a is set on an upward trajectory. In the near term, major R143a plants show no clear intention to raise offers before the holiday, and both single-component and blended fluorinated refrigerants maintain a high and firm pattern. In the long term, amid strong demand across the industry chain, R143a prices are expected to follow the upward movement of blended refrigerants after the holiday.

For domestic trade of blended refrigerant R507A in the East China market, offers from major manufacturers remain firm. From January to May 2026, overall shipments of R507A outperformed the same period last year. However, entering June, the shipment pace of R507A has slightly slowed compared to earlier months. This week, some plants are accepting high-level orders for R507A while actively selling other grades. Market sources indicate that major plants continue to hold firm on offers. Chempricehub expects the mainstream price of R507A in the East China market to range between 52,000 and 54,000 yuan/ton.
