About Wuhan Yunhong - Fertilizers Supplier in China

China‑based Wuhan Yunhong lists five active fertilizer products. The catalogue is organized under the broad categories of general fertilizers and urea, which are classified in HS Chapter 31 (e.g., HS 3105 for compound fertilizers). The supplier’s portfolio includes three granular NPK blends, a slow‑release compound, and a methylene urea solution, each identified by specific nutrient ratios and particle‑size ranges. All five items are presented without additional certifications in the supplied data, indicating that buyers should verify standard quality documents independently.

The product list features Npk 20‑5‑10 and Npk 18‑3‑18 formulated for golf‑green applications with granule sizes of 0.5‑1.5 mm, and Npk 32‑0‑8 described as a universal type with a broader 0.5‑2.5 mm size range. A Mu Slow Release Compound Fertilizer is offered, typically designed to release nutrients over 8‑12 weeks in temperate soils. Methylene Urea, a liquid nitrogen source, is also included, commonly used to boost nitrogen efficiency in high‑value cropping systems.

Product Range and Specialties of Wuhan Yunhong

The catalogue concentrates on compound nitrogen‑phosphorus‑potassium (NPK) blends that match common agronomic specifications. Golf‑green grades such as 20‑5‑10 and 18‑3‑18 are usually produced with low salt index, tight particle‑size distribution (0.5‑1.5 mm) and moisture content below 5 %. Universal NPK 32‑0‑8 targets broader field crops and often carries a bulk density around 800‑900 kg m‑3. The Mu slow‑release product typically incorporates a polymeric coating that limits nitrogen leaching, and manufacturers often quote a release rate of 30‑50 % nitrogen per month. Methylene urea is supplied as a 28 % nitrogen liquid, with a typical pH of 7‑8 and a cloud point near 0 °C, making it suitable for both bulk tank and bagged shipments.

Trade and Export Information - Wuhan Yunhong

Chinese fertilizer exporters routinely ship under HS 3105 (compound fertilizers) and HS 3102 (urea) to markets in Southeast Asia, Sub‑Saharan Africa, and Latin America, where soil fertility enhancement drives demand. Buyers usually require a Certificate of Analysis, a Phytosanitary Certificate for organic‑matter limits, and compliance with the EU Fertiliser Regulation (Regulation (EU) 2019/1009) when targeting European ports. Standard export packaging includes 25 kg polypropylene bags for granular NPKs and 200 L IBCs for liquid methylene urea, with typical loading of 20‑ft containers holding 18‑20 tons of granular product. Common Incoterms are FOB Shanghai or CIF destination ports, and freight forwarders often arrange moisture‑controlled storage for the slow‑release formulation to preserve coating integrity.

Sourcing from Wuhan Yunhong - Buyer Guidance

When sourcing from Wuhan Yunhong, request a recent Certificate of Analysis that details nitrogen, phosphorus (P₂O₅), potassium (K₂O) percentages, particle‑size distribution, moisture content, and heavy‑metal limits (e.g., Cd < 0.05 mg kg‑1). For the slow‑release compound, ask for a release‑profile test report (e.g., EN 13223) and coating thickness data. Verify that the methylene urea shipment includes a Material Safety Data Sheet (MSDS) and a purity certificate stating ≥ 28 % nitrogen. Confirm packaging specifications (bag weight, liner type) and ensure that the supplier can meet your preferred Incoterm and container size before placing a purchase order.

What nutrient ratios are offered in the NPK golf‑green products?

Wuhan Yunhong provides Npk 20‑5‑10 and Npk 18‑3‑18 blends, both formulated for fine‑tuned turf nutrition and supplied in granules sized 0.5‑1.5 mm.

Is the Mu Slow Release Compound Fertilizer coated?

Yes, the Mu product is a coated compound designed to release nitrogen gradually over several weeks; buyers typically request a release‑profile test (e.g., EN 13223) to confirm performance.

What is the typical packaging for the granular fertilizers?

Granular NPKs are usually packed in 25 kg polypropylene bags, which can be stacked in standard 20‑ft containers holding up to 18 tons.

Which certification documents should a buyer request for the methylene urea?

Buyers should ask for a Certificate of Analysis, a Material Safety Data Sheet, and a purity certificate confirming at least 28 % nitrogen content.

What HS codes apply to the listed products?

The granular NPK blends fall under HS 3105 (compound fertilizers) while methylene urea is classified under HS 3102 (urea and derivatives).

Which markets commonly import Chinese fertilizer products?

Typical import destinations include Southeast Asian countries, African nations such as Kenya and Tanzania, and Latin American markets like Brazil and Chile, where demand for soil amendment is strong.

What quality standards are usually required for these fertilizers?

Buyers often require compliance with ISO 9001 quality management, the EU Fertiliser Regulation limits on heavy metals, and grain‑size uniformity within ± 0.2 mm of the specified range.

What are the usual lead times for bulk orders?

Chinese fertilizer exporters generally quote 30‑45 days from order confirmation to vessel loading, depending on production scheduling and container availability.
