Opinions

What is driving the structural shift in China's ammonium sulfate supply mix?

This by-product dependency creates a unique pricing dynamic: ammonium sulfate supply follows caprolactam and coke plant operating rates, not fertilizer demand. When main-product margins weaken, plants cut output, tightening ammonium sulfate supply regardless of agricultural season. Buyers should track caprolactam spreads and coking utilization as leading indicators for ammonium sulfate availability, rather than relying solely on fertilizer market fundamentals.

How will the EU carbon border tax reshape China's ammonium sulfate exports to Europe?

European buyers have already shifted purchasing patterns. Since 2023, many have downgraded from premium caprolactam-grade to cheaper coking-grade ammonium sulfate to control costs amid inflation and energy crises. This 'race to the bottom' means Chinese exporters competing on price alone face a double squeeze: CBAM erodes margins while quality premiums disappear. Product differentiation through granulation or low-biuret specs may be the only sustainable path.

Why is China's ammonium sulfate export price rising despite record output?

The export price surge masks a structural problem: China's capacity reached 27.63 million tons in 2025, with 80% export dependence. The July 2026 export inspection policy adds CNY 30-80 per ton in compliance costs and 3-5 days of delays. This will likely widen the gap between premium caprolactam-grade and lower-cost coking-grade material, as buyers weigh quality against expedited shipping.

Overview

Ammonium sulfate (CAS 7783-20-2) is a white crystalline or granular solid, readily soluble in water, with a melting point above 280 °C (decomposing). It is a versatile inorganic compound serving primarily as a nitrogen fertilizer and an industrial processing aid.

Agriculture: a classic nitrogen fertilizer that also supplies sulfur, helping to adjust soil pH in alkaline soils and improve crop yield and quality.
Textiles & leather: used as a dyeing auxiliary, flame retardant, and in leather tanning processes.
Pharmaceuticals: a raw material in the synthesis of certain antibiotics and vitamins.
Construction: acts as a concrete expansion agent, increasing volume and strength while preventing cracks.
Industrial processing: byproduct from caprolactam, coke-oven, and flue-gas desulfurization operations, with grades varying by purity and crystal size.

China dominates global supply, with production largely tied to caprolactam and coking units as a byproduct. Exports have surged in recent years, particularly to Brazil, India, and Southeast Asia, though prices have faced downward pressure amid intense competition. The market is shifting toward higher-quality, large-crystal grades for premium blended fertilizers.

Key domestic producers:
Sinopec – caprolactam-grade ammonium sulfate.
Juli Chemistry – high-purity crystalline grades.
