AMMONIUM SULPHATE (Caprolactam Grade)

    Nitrogen (N): ≥21% | Sulfur (S): ≥24% | Free Acid: ≤0.05% | Moisture: ≤0.2% | Purity: >99.5%.
    Production Process
        Derived as a by-product from caprolactam (nylon-6 precursor) manufacturing via crystallization and purification.
    Applications
        Agriculture: Premium water-soluble fertilizer for high-value crops (fruits, vegetables).
        Industrial: Pharmaceutical fermentation (antibiotics) and rare earth mining (ion-exchange agent).
    Primary Markets
        China dominates global production (70% capacity), with major exports to India, Southeast Asia, and Brazil.  

AMMONIUM SULPHATE (Steel Grade)
    Nitrogen (N): ≥20% | Sulfur (S): ≥24% | Heavy Metals (Fe, Mn): ≤50 ppm | Particle Size: 2–4 mm.
    Production Process
        Recovered from steel mill off-gases (blast furnaces/coking plants) through neutralization and crystallization.
    Applications
        Metallurgy: Enhances conductivity in electroplating baths and acts as a rust inhibitor.
        Agriculture: Bulk nitrogen source for staple crops (wheat, corn) in low-cost markets.
    Primary Markets
        China and Russia; prices fluctuate with steel industry cycles (2023: $300–450/ton FOB China).

AMMONIUM SULPHATE (MMA Grade)

    Nitrogen (N): ≥20% | Sulfur (S): ≥24% | Organic Residues: ≤0.1% (requires purification).
    Production Process
        By-product of methyl methacrylate (MMA) synthesis, purified to remove organic impurities.

AMMONIUM SULPHATE (Iron Phosphate Grade)

    Nitrogen (N): ≥20% | Sulfur (S): ≥24% | Phosphorus (P): ≤0.5%.
    Production Process
        Recovered from lithium iron phosphate (LFP) battery recycling via leaching and purification.
    Applications
        Energy Storage: Precursor for EV battery cathode materials.
        Agriculture: Sulfur supplementation in sulfur-deficient soils (India, Brazil).
    Primary Markets
        China leads global recycling (80% capacity), followed by Europe; demand driven by EV growth (2030: triple 2024 levels).
