We are seeking reliable suppliers for high agricultural-grade customized NPK granular fertilizers in the formulation 16-16-16, enriched with 2.5% MgO, Amino Acids, Humic & Fulvic Acid (10%), and trace elements (TE). The product must have uniform, hard granules suitable for large-scale farming, ensuring consistent nutrient composition and performance.

Similarly, we require suppliers for the 13-13-13-19 formulation with the same additives. Suppliers must clarify the “19” component and ensure the same high-quality standards, granule uniformity, and agricultural-grade performance.

Suppliers should be able to provide samples for evaluation and clearly state MOQ, production capacity, lead time, and certifications (COA, MSDS, TDS). Shipments will be CIF to Kwangyang Port, South Korea, with estimated quantities of 200–500 MT per formulation. Only experienced manufacturers or authorised exporters with proven quality will be considered.
