A globally traded fertilizer — tightest where sulfur runs short
Wherever high-yield agriculture meets sulfur-deficient soils — South America, North America, Africa, South and Southeast Asia — ammonium sulphate demand is structural, not cyclical. Most seaborne supply originates in China. Below: the drivers everywhere, and a spotlight on the market we know best.
Import-reliant markets
Many major agricultural economies produce little or no AMS domestically — nearly every tonne is imported, creating some of the largest fertilizer trade flows in the world. Brazil is the clearest example.
Sulfur-hungry crops
Soybean, corn, coffee, sugarcane, cotton, wheat and rice all draw heavily on sulfur — and sulfur-deficient soils are common across South America, North America, Africa and Asia. The demand is structural, season after season.
Granular is the global standard
Granular Chinese material is the reference product across import markets worldwide — the supply Haunui delivers, direct from the producer.
Two nutrients in one granule
Ammonium sulphate [(NH₄)₂SO₄] delivers nitrogen and sulphur together, both in forms the plant takes up immediately.
Stable ammoniacal nitrogen — holds in the root zone and resists leaching better than nitrate.
Fast-acting sulfate sulfur — directly plant-available, with no conversion delay.
Applied direct or blended into NPK formulas; a low-cost route to guaranteed sulfur, well-suited to limed, high-pH and sulfur-deficient soils worldwide.
Soybean, corn, coffee, cane, cotton and wheat — the world’s biggest export crops and its heaviest sulfur feeders.
Direct from a listed producer — no broker chain
Our granular ammonium sulphate is produced by a publicly-listed Chinese manufacturer with three decades in agricultural inputs. We keep the producer’s identity off the open web and disclose full credentials to qualified buyers during due diligence.
A publicly-listed, three-decade producer means transparency, scale and stability — and Haunui’s direct relationship means one accountable counterparty between the mill and your port.
Granular, agricultural grade
Typical granular values — final certified figures per the CCIC / SGS report at the port of loading.
Grade: Granular, agricultural grade · HS 3102.21 (NCM 3102.21.00 for Brazil; confirm your national tariff code) · Inspection: CCIC / SGS Quality & Quantity survey at the load port.
