Asia
In Asia, STPP prices moved firm during Q1 2026 as phosphate-chain costs strengthened and logistics risk increased after the Iran war disrupted Strait of Hormuz trade. The impact was mainly indirect, through sulfur, phosphoric acid, energy, and freight. Since sulfur is used to produce sulfuric acid for phosphate processing, disruption in seaborne sulfur tightened the cost base for STPP producers. Asian buyers from detergents, ceramics, and water-treatment applications maintained steady procurement, but demand was not strong enough to create a sharp price rise.
Europe
Europe also saw firm STPP sentiment as the region remained exposed to imported phosphate-chain materials and higher freight costs. Daily sulfur shipments of 45,000-50,000 mt through Hormuz were affected, raising concern over sulfuric acid and phosphoric acid availability. Africa relied on the Middle East for around 48.0% of its sulfur supply, which also mattered for Europe because North African phosphate and phosphoric acid flows are important to the regional phosphate value chain. Detergent and industrial cleaning demand remained steady, keeping the market supported.
North America
North America stayed comparatively stable in Q1 2026, supported by stronger domestic availability of phosphate and soda ash inputs and lower exposure to direct Hormuz-linked raw material disruption. The main pressure came from logistics rather than feedstock shortage, as chemical container exports from the US Gulf Coast rose 12.0% in March and 20.0% surge capacity was available to manage disruptions. STPP demand from detergents, water treatment, food processing, and industrial cleaning remained steady, but buyers continued need-based procurement. This kept the market balanced compared with Asia and Europe, where sulfur and phosphate-chain risks were more pronounced.
Analyst Insight
According to Procurement Resource, near-term STPP prices may remain firm if sulfur, phosphoric acid, freight, and energy risks persist. Asia and Europe remain more exposed, while North America should stay relatively steadier.

Asia
In Q4 2025, the Asian STPP market faced softer conditions as demand from detergents, water treatment, and industrial sectors moderated toward year-end. Chinese suppliers reported cautious purchasing behavior and conservative inventory management among buyers. Although export activity continued, sufficient raw material availability and balanced operating rates prevented supply-side pressure. Market participants focused on maintaining inventories and managing year-end procurement requirements, resulting in a generally subdued trading environment.
Europe
The European STPP market remained relatively stable during Q4, supported by ongoing demand from detergent, food-processing, and industrial cleaning sectors. Buyers continued to procure cautiously amid mixed economic signals and moderate industrial activity. Supply availability remained adequate through imports and regional distribution networks, while inventory management played a central role in purchasing decisions. Market sentiment remained balanced despite limited growth in downstream consumption.
North America
North American STPP markets exhibited stable fundamentals through Q4 2025. Demand from cleaning products, food processing, and water treatment applications remained consistent, though year-end inventory adjustments moderated procurement activity. Suppliers benefited from steady domestic production and balanced feedstock availability, helping avoid major supply disruptions. Buyers largely maintained need-based purchasing strategies, resulting in a controlled and relatively steady market environment as the year concluded.
