Fertilizer

Bulk Commercial Fertilizer Supplier | NPK, Soluble & Specialty Formulas

Zouping Jinxing Chemical manufactures and exports commercial-grade fertilizers tailored for international distributors, regional agricultural blenders, commercial plantations, and bulk importers.

Rather than supplying generic commodity formulations, we focus on guaranteed nutrient purity, precise physical granule integrity, and batch-to-batch consistency. Our product portfolio includes NPK compound fertilizers, high-purity water-soluble fertigation grades, nitrogen/phosphate/potassium straight fertilizers, and custom micronutrient-enriched blends.

Fertilizer Portfolio by Chemistry & Application

NPK Compound Fertilizers (High-Tower & Granular)
Produced via steam granulation or high-tower melt technology to ensure every single granule contains the exact declared N-P2O5-K2O ratio.

Balanced Formulations (e.g., 15-15-15, 19-19-19): Ideal for baseline soil nourishment and multi-crop basal applications.

High-Nitrogen Formulations (e.g., 30-10-10, 25-5-5): Engineered for vegetative expansion and early-stage crop boosting.

High-Potassium Formulations (e.g., 12-12-17+2Mg, 10-20-30): Designed for fruit fill, grain sizing, stress resistance, and late-stage crop finishing.

Low-Chloride / SOP-Based Grades: Specialized formulas using Potassium Sulfate (K2SO4) instead of MOP (KCl) for chloride-sensitive crops (tobacco, fruits, greenhouse vegetables).

Water-Soluble Fertilizers (Fertigation & Foliar)
Fully soluble crystalline powders engineered for zero-residue liquid injection via drip irrigation, center pivots, and foliar spray rigs.

Drip Irrigation Formulations: 100% water-soluble with turbidity-free dissolution to prevent emitter clogging and filter blinding.

Specialty Mono-Nutrients: Including Monoammonium Phosphate (MAP 12-61-0), Monopotassium Phosphate (MKP 0-52-34), and Calcium Ammonium Nitrate (CAN).

Technical & Physical Specifications

Parameter Category	Standard Commercial Specification	Why It Matters for Bulk Procurement
Nutrient Declaration	Total N, Available P2O5, Water-Soluble K2O (Tolerance within +/- 1.1%)	Guarantees compliance with destination country fertilizer acts and import regulations.
Physical Form	Granular (2.0 - 4.75 mm ≥ 90%) or Crystalline Powder	Ensures even mechanical field spreading, minimal segregation in bulk blends, and zero dust loss.
Granule Hardness	≥ 25 N to 40 N per granule (High-Tower grades)	Prevents crushing, degradation, and fines generation during loading, ocean transit, and bagging.
Moisture Content	≤ 1.0% (Granular NPK) / ≤ 0.5% (Water-Soluble)	Inhibits caking, degradation, and moisture absorption during long-distance maritime transport.
Chloride (Cl-) Content	Low-Cl (≤ 3.0%) or Cl-Free options available	Protects sensitive crop root zones and soil salinity balances.
Water Solubility	100% rapid dissolution; Insolubles ≤ 0.2% (Soluble grades)	Protects drip emitters, dosing pumps, and nozzles from physical clogging.

Marine Transport, Packaging & OEM Capabilities

Ocean freight conditions demand rigorous packaging to protect physical granule integrity and moisture barriers. We offer fully customizable commercial packaging formats:

Retail & Plantation Bags:

25 kg or 50 kg Woven PP bags with PE inner liners (UV-stabilized optional).

Bulk Jumbo Bags:

500 kg, 1,000 kg, or 1,200 kg FIBC Jumbo Bags equipped with bottom discharge spouts.

Private Label / OEM Printing:

Custom bag layout, multi-color flexo printing, local language regulatory markings, and local brand registration support.

Anti-Caking Surface Treatment:

Surface-coated with organic anti-caking oils and conditioning powders for tropical high-humidity storage environments.

Quality Control & International Compliance

To eliminate risk for global importers, our factory operates under a multi-stage Quality Management System:

Raw Material Assay: Every incoming batch of synthetic ammonia, phosphoric acid, and potash undergoes purity verification.

In-Line Process Monitoring: Automated temperature and moisture control during granulation to ensure consistent particle size distribution.

Pre-Shipment Inspection (PSI): Third-party verification (SGS, Intertek, or CCIC) available upon request for nutrient assay, heavy metal limits (Cd, Pb, As, Hg), and net weight accuracy.

Documentation Package: Complete documentation set provided for fast customs clearance:

Certificate of Analysis (COA) matched to exact production batch

Safety Data Sheet (SDS) compliant with GHS standards

Certificate of Origin (Form E, Form F, or General COO)

Phytosanitary / Heavy Metal Compliance Certificates where required

FAQ

Q: What is the difference between compound NPK and blended fertilizer?

A: A compound fertilizer contains multiple nutrients in a product manufactured to a defined analysis, while a blended fertilizer is produced by physically mixing separate fertilizer materials. The choice depends on the application, nutrient requirements, and spreading or blending conditions.

Q: Which NPK ratio is best for crops?

A: There is no single NPK ratio suitable for every crop or field. The appropriate ratio depends on crop nutrient demand, soil test results, growth stage, expected yield, and the existing nutrient management programme.

Q: What should I check when buying NPK fertilizer?

A: At minimum, check the N-P₂O₅-K₂O analysis, nutrient forms where relevant, moisture, particle size, granule strength, chloride content, packaging, batch COA, and applicable compliance requirements.

Q: Is water-soluble fertilizer suitable for fertigation?

A: Only when the product specification confirms adequate water solubility and suitability for the intended fertigation system. Buyers should also consider insoluble residue and compatibility with filters and emitters.

Q: Can you manufacture custom N-P-K ratios or add specific secondary micro-nutrients?

A: Yes. We support custom formulation requests for bulk orders. We can integrate Magnesium (MgO), Sulfur (S), Calcium (CaO), and chelated trace elements (Zinc, Boron, Iron, Manganese) into both compound granules and soluble blends.

Q: How do you prevent caking during long-haul ocean container transit?

A: We control finished product moisture below 1.0%, utilize double-layer PE inner liners in all bags, and apply premium hydrophobic anti-caking agents to every granule prior to packaging.

Q: Can we request pre-shipment inspection by SGS or Intertek?

A: Yes. We welcome independent third-party inspection at the loading port or production facility to verify weight, nutrient analysis, and packaging integrity before vessel departure.
