The US insoluble sulphur market strengthened during late June 2026 as improving tyre-sector demand and tighter import availability supported higher prices. After subdued buying earlier in the month, procurement activity accelerated toward the end of June as replacement tyre production, EV tyre manufacturing, and distributor restocking increased consumption. Domestic production continued to supply most market requirements, but constrained imports and elevated logistics costs tightened prompt availability. Feedstock costs remained supportive despite stabilizing toward the month-end, while buyers became more active in securing volumes. The recovery in downstream automotive demand helped reverse the weaker sentiment seen earlier in June, leaving the market on firmer footing entering July. Looking ahead, insoluble sulphur prices are expected to remain relatively stable as healthy tyre-sector demand and balanced supply conditions continue supporting the market, although feedstock costs and import availability will remain key factors influencing future price direction.
