By Q1 2025, Caustic Soda prices in the USA (Lye FOB Houston) stabilized at $ 495.6/MT, showing a slight increase of +1.85% from Q4 2024. This stabilization can be attributed to a return to further normal demand situations after the vacation season, as artificial consumption generally situations off post festive period.

As a result, the request set up a balance, leading to a slight increase in prices as the request acclimated to the ongoing requirements of the manufacturing sector.

Caustic Soda Price Trend Q2 2025

In Q2 2025, according to the PriceWatch, Caustic Soda prices in the USA (Lye FOB Houston) experienced a -4.17% decrease, settling at USD 475 per metric ton.
