US Tetrapotassium Pyrophosphate (TKPP) markets advanced through March as seasonal procurement and logistics tightened supply and lifted landed costs. Early-mid March purchases accelerated ahead of spring promotions, while higher ocean freight and tighter prompt cargoes pushed importers to secure additional allotments. A planned maintenance turnaround at a domestic TKPP unit trimmed immediate availability, strengthening sellers' stance. Sentiment shifted from cautious restocking to active buying as distributors replenished inventories ahead of nationwide promotions and seasonal industrial demand upticks. Demand was strongest in detergents and household cleaners, with production of tablets and liquids rising for spring campaigns; processed-food buyers also supported through expanded ready-meal runs. Battery-electrolyte orders remained niche and did not materially affect volumes, while industrial-cleaning demand was softer. Freight and feedstock pressures underpinned the move, with the Shanghai-Los Angeles index posting a double-digit gain for the month. Looking ahead, prices could rise roughly into April amid persistent costs and cargo tightness, with renewed downstream demand.
