Starting from May 1, 2026, China will comprehensively suspend exports of ordinary industrial-grade sulfuric acid and smelting by-product sulfuric acid （only small-volume exports of electronic-grade high-purity sulfuric acid will be allowed upon approval）. As the world's largest sulfuric acid producer （accounting for more than 40% of global output）, this move has already triggered sharp fluctuations in spot prices in major importing countries such as Chile, Indonesia, and India, and has created substantial delivery and cost pressures on segments highly dependent on China's sulfuric acid supply, including fertilizer production, copper and nickel smelting, and battery metal processing. Relevant enterprises need to immediately assess supply chain resilience and alternative pathways.

Event Overview

According to publicly available information, starting from May 1, 2026, China has officially implemented a policy suspending exports of ordinary industrial-grade sulfuric acid and smelting by-product sulfuric acid; electronic-grade high-purity sulfuric acid is exempt, but requires special approval and only limited exports are permitted. Confirmed market reactions currently include: Chile's sulfuric acid spot prices rising 44% month-on-month, while sulfur prices have increased 70% under the combined impact of geopolitical factors and tighter exports.

Which Market Segments Will Be Affected

Direct Trading Enterprises

Cause of impact: Existing sulfuric acid export channels from China to Chile, China to Indonesia, and China to India have been cut off immediately, reducing long-term contract fulfillment capacity to zero; the approval mechanism for electronic-grade sulfuric acid exports still lacks clear implementation details and quota scale. The impact is mainly reflected in a sharp decline in order execution rates, increased risk of customer claims, and an urgent need to re-examine export qualifications and compliance documentation systems.

Raw Material Procurement Enterprises

Cause of impact: Fertilizer plants, copper smelters, and nickel-cobalt hydrometallurgical plants generally rely on Chinese sulfuric acid as their main source under long-term contracts, while alternative suppliers have long response cycles, poor transportation compatibility （for example, liquid sulfuric acid has high storage and transportation requirements）, and questionable quality stability. The impact is mainly reflected in significantly rising procurement costs, pressure on inventory safety thresholds, and the risk of phased production cuts on some production lines.

Processing and Manufacturing Enterprises

Cause of impact: Downstream products such as battery cathode precursor materials, phosphate fertilizers, and titanium dioxide are sensitive to sulfuric acid purity, impurity content, and continuity of supply. China's export suspension has led to concentrated exposure of regional raw material shortages, especially in regions such as South America and Southeast Asia where local supporting capacity is insufficient. The impact is mainly reflected in frequent adjustments to process parameters, reduced batch consistency, and passive increases in unit energy consumption and spent acid treatment costs.

Supply Chain Service Enterprises

Cause of impact: Standardized service processes previously formed around China's sulfuric acid exports by logistics, warehousing, customs declaration, and inspection agencies （such as cross-border multimodal transport solutions for hazardous chemicals and fast-track channels for issuing certificates of origin） are facing a loss of applicability. The impact is mainly reflected in longer document processing times, declining utilization of regional transit warehouses, and a structural shift in third-party testing demand toward high-purity / small-batch directions.

What Key Points Should Relevant Enterprises or Practitioners Pay Attention To, and How Should They Respond at Present

Pay Attention to Subsequent Official Statements or Policy Changes

What is currently more worth attention is whether the Ministry of Ecology and Environment, the Ministry of Commerce, and the General Administration of Customs will issue supplementary explanations on the “approval standards for electronic-grade high-purity sulfuric acid,” the “definition boundary of smelting by-product sulfuric acid,” and the “arrangements for the policy transition period”; such documents will directly affect the feasibility assessment of alternative export pathways.

Pay Attention to Changes in Key Product Categories, Key Markets, or Key Business Links

Analysis shows that although electronic-grade high-purity sulfuric acid is exempted, its share of production capacity is extremely low and the certification cycle is long, making it difficult to cover the supply gap in industrial-grade demand; enterprises should give priority to reviewing clauses in their procurement contracts concerning sulfuric acid grade, application, delivery method, and other terms, identify business links with the strongest irreplaceability （such as the leaching process in hydrometallurgical copper extraction）, and launch graded response plans.

Differentiate Between Policy Signals and Actual Business Implementation

Observation shows that this suspension is an administrative order-type regulatory measure rather than a tariff or quota management tool, which means there is no buffer period and no phased implementation rhythm; enterprises should not make judgments based on the logic of “policy testing—market feedback—fine-tuning,” but should instead treat it as a rigid constraint already in effect and carry out supply chain restructuring accordingly.

Prepare in Advance for Procurement, Supply Chain, Communication, or Contingency Plans

From an industry perspective, feasible short-term actions include: initiating feasibility assessments for localized sulfur-to-sulfuric acid production （especially in areas of Chile and Indonesia that already have sulfur resources）; jointly evaluating with existing Chinese suppliers the potential for internal recycling and utilization of by-product acid; and simultaneously connecting with sample testing and logistics verification for non-mainstream supply sources such as Morocco, the United States, and Russia.

Editorial Viewpoint / Industry Observation

Analysis shows, this export suspension is not an isolated trade measure, but a symbolic milestone in China's strengthened overall planning for supply security of key industrial intermediate products. At present, it is more like a supply-side contraction event that has already produced substantive consequences, rather than a policy signal awaiting observation; the industry needs to continue paying attention to two points: first, whether domestic sulfuric acid capacity in China will shift to absorption by domestic demand due to export restrictions （such as increased concentration in phosphate compound fertilizers）, thereby indirectly affecting the upstream sulfur procurement landscape; second, whether other major producing countries will seize the opportunity to accelerate the establishment of regional sulfuric acid reserves or alliance-based supply mechanisms.

Conclusion:
This policy marks the formal entry of the global sulfuric acid supply chain into a phase of regionalized restructuring. Its industry significance does not lie in short-term price fluctuations, but in exposing the vulnerability of a highly concentrated intermediate product supply structure. At present, it is more appropriate to understand this as a mandatory supply chain stress test——the core of enterprise response is not to wait for policy relaxation, but to systematically redesign raw material acquisition logic and production capacity layout benchmarks based on the premise that “Chinese sulfuric acid will be unavailable in the long term.”
