Sodium Lignosulphonate prices rose through March as tightening availability, freight and insurance costs, and panic buying reshaped the US spot market. Early March conditions were relatively balanced, but geopolitical risk and disciplined allocations reduced spot offerings and prompted cover for near-term needs. Municipal and infrastructure buying ahead of spring and summer projects provided firm underlying demand for sodium lignosulphonate, even as residential construction remained cautious. The combined effect was a shift from balanced markets to a constrained tone through the month. Demand patterns varied by sector: infrastructure remained strong for concrete admixtures using sodium lignosulphonate, while municipal programs supported dust suppression. In contrast, residential construction was weak, constraining forward buying for ready-mix concrete. Pulp-and-paper and animal-feed binder applications for sodium lignosulphonate stayed steady. Supply factors included higher caustic soda and energy costs squeezing margins, while logistics frictions and disruption pushed landed costs higher. Outlook suggests near-term gains for sodium lignosulphonate ahead of spring maintenance and infrastructure activity, though outcomes depend on shipping routes and allocations.
