For over 15 years, GreenHarvest Fertilizer Co., Ltd. has provided full custom fertilizer manufacturing services to agricultural importers, distributors, and brand owners across 60+ countries. Our vertically integrated production facility enables complete customization—from nutrient formulation and granule characteristics to packaging design and private-label branding.
Whether you need a specific NPK ratio to match local soil conditions, a unique granule color for brand differentiation, or fully branded packaging with your company logo and multilingual labeling, our engineering and quality control teams deliver products that meet your exact specifications. Every custom order is backed by our ISO 9001 certified quality management system and SGS-tested production standards.
We handle the entire process: formula development, sample production, mass manufacturing, quality control testing, custom packaging, and export documentation. You receive a market-ready, private-label fertilizer product shipped directly to your port.
Every aspect of your fertilizer product can be tailored to your market requirements—from nutrient composition and physical characteristics to packaging design and brand presentation.
Custom NPK ratios from 1-1-1 to specialized blends. Add secondary nutrients (Ca, Mg, S) and micronutrients (Zn, B, Mn, Fe, Cu, Mo) based on your soil test data and crop requirements. MOQ 100T.
Choose granule diameter to match your application method: 2-4mm standard granular, 1-2mm mini granular for precision spreading, 4-6mm large granular for basal application, or prilled 1-3mm for solution grade.
Custom granule coloring for brand differentiation and visual identification. Standard options include natural, green, blue, red, yellow, and custom color matching. Dyes are non-toxic and environmentally safe.
Full range of packaging options: 10kg small bags, 25kg and 50kg PP woven bags, 1000kg jumbo bags (FIBC), and custom drum packaging. Pallet wrapping and container loading optimization available.
Full private-label service with your brand logo, company name, and product design printed directly on bags. Up to 6-color printing on PP woven, kraft paper, and PE bags. MOQ 50T for OEM branding.
Product labels and packaging text in your local language. We support English, Spanish, Arabic, French, Portuguese, Russian, Thai, and other languages. Labels include nutrient content, usage instructions, and safety information.
A structured, transparent process from initial consultation to final shipment. Each step includes dedicated support and quality verification to ensure your custom product meets every specification.
Share your requirements: target NPK ratio, crop type, soil conditions, granule size, color, packaging specifications, brand design, and order volume. Our technical team reviews feasibility and provides a detailed quotation within 24 hours, including unit pricing, MOQ, and lead time.
We produce a 1-5kg sample batch matching your exact formula and specifications within 5-7 days. The sample is shipped via DHL or FedEx (buyer pays freight) along with a Certificate of Analysis (COA). You test and approve the sample before mass production begins.
Upon sample approval and 30% deposit payment, mass production begins. Our QC laboratory tests every batch for nutrient content, moisture, granule size distribution, and physical properties. Production takes 20-30 days for custom formulas, with progress updates provided weekly.
Custom packaging with your brand design is applied, followed by pallet wrapping and container loading optimization. Full export documentation (COA, Packing List, Commercial Invoice, B/L, Certificate of Origin) is prepared. Shipment departs from Qingdao Port to your destination port.

Common questions from buyers considering our OEM and custom fertilizer manufacturing service.
The MOQ for custom NPK ratio fertilizer is 100 metric tons. For OEM private label packaging with your brand logo and design, the MOQ is 50 metric tons.

We may offer lower MOQ for first-time trial orders—please contact our sales team to discuss your specific needs.
Production lead time for custom fertilizer is 20 to 30 days after sample approval and deposit payment. This includes formula blending, granulation, quality control testing, and custom packaging. Standard products without customization take 7 to 15 days. Sample development takes an additional 5 to 10 days before mass production begins. Shipping time depends on the destination port.
