Map 12-61

MAP 12-61 is a fully water-soluble fertilizer. You must ensure the Nitrogen (N) content is 12% and the Phosphorus (P2O5) content is 61%. For fertigation and foliar spray, the water solubility must be 100% with a very low insoluble matter percentage (typically <0.1%). Additionally, check the pH value (usually between 4.0 and 4.5 in a 1% solution) to ensure compatibility with other nutrients.

For these systems, the moisture content should be below 0.2% to prevent caking. It is critical to request a heavy metal analysis report, ensuring that levels of Lead (Pb), Cadmium (Cd), and Arsenic (As) are well within international safety limits. The product should be free of Chlorine (Cl) and Sodium (Na) to avoid soil salinity and crop toxicity.

Suppliers should provide an ISO 9001 certification for quality management. Depending on the destination, you may require a REACH registration (for the EU) or a Certificate of Analysis (COA) that matches the standards of your local Ministry of Agriculture. Ensure the supplier provides a Material Safety Data Sheet (MSDS) for safe handling and transport.

MAP 12-61 is primarily used during the early growth stages and root development phase due to its high phosphorus content. It is highly effective for pH buffering in alkaline soils. Its high purity makes it the preferred choice for drip irrigation, sprinkler systems, and foliar application in high-value crops like greenhouse vegetables and fruits.

While MAP is generally classified as non-hazardous, you must confirm the HS Code (typically 310540) with the supplier to ensure correct customs declaration. Use moisture-proof packaging, such as 25kg or 50kg PP/PE bags with inner liners, and request palletization with shrink-wrap to prevent damage during sea transit. For large volumes, bulk liners in containers can be a cost-effective strategy.

Always utilize Trade Assurance services or Letter of Credit (L/C) for large-scale transactions to protect your funds. Before placing a bulk order, hire a third-party inspection agency like SGS or Intertek to perform a Pre-Shipment Inspection (PSI) to verify the chemical composition and weight. You can find verified manufacturers with audited reports on Made-in-China.com to ensure supplier legitimacy.

Fertilizer prices are highly sensitive to raw material costs (ammonia and phosphoric acid) and energy prices. Negotiate based on seasonal demand cycles—buying during the off-season can yield 10-15% discounts. Request tiered pricing based on volume (e.g., 20ft FCL vs. 100MT) and ask for FOB pricing to maintain better control over your logistics costs.
