NPK roller granule fertilizer manufacturers in China play an important role in supplying compound fertilizers to Southeast Asian markets, particularly Vietnam. With stable agricultural demand for rice, vegetables, fruit trees, and industrial crops, Vietnam relies on imported NPK fertilizers that offer consistent quality and adaptable formulations.
Roller granulation technology is widely used by Chinese manufacturers due to its production efficiency, controllable nutrient ratios, and suitability for export-oriented fertilizer products.
Hebei Wangdalei Trading Co., LTD works with established manufacturing partners in China to supply NPK roller granule fertilizers designed for Vietnam’s agronomic and logistical conditions.
Roller granule fertilizer manufacturing is based on dry compaction. Raw materials such as nitrogen, phosphorus, and potassium sources are accurately dosed and mechanically pressed into uniform granules.
Key technical features include:
No high-temperature drying, preserving nutrient stability
Consistent granule size distribution
Reduced moisture content for improved storage
Lower production energy consumption compared to traditional methods
This process allows manufacturers to produce a wide range of NPK formulations while maintaining physical strength and nutrient uniformity.
Manufacturers supplying Vietnam typically adjust formulations to match local crop demand and soil fertility practices.
| Parameter | Typical Range |
|---|---|
| Granule size | 2–4 mm |
| Moisture content | ≤ 2.5% |
| Total nutrient content | 40%–60% |
| Granule hardness | Suitable for transport and spreading |
| Color | Natural or customer-specified |
Such specifications help ensure smooth importation, handling, and field application in Vietnam’s climate.
NPK roller granule fertilizer manufacturers are not only responsible for production but also for maintaining supply consistency throughout the agricultural season.
Their role includes:
Ensuring batch-to-batch nutrient accuracy
Supporting customized formulations
Providing stable output for long-term contracts
Meeting export documentation and inspection standards
These factors are particularly important for Vietnamese distributors who require predictable supply during planting cycles.
Quality control is a core part of roller granule fertilizer manufacturing. Standard inspection procedures typically include:
Raw material testing
Nutrient content verification
Granule size and strength assessment
Moisture and anti-caking evaluation
Products are released for export only after meeting agreed technical parameters, reducing the risk of quality variation in overseas markets.
Manufacturers supplying Vietnam often cooperate with exporters to ensure packaging meets transportation and storage requirements.
Common options include:
25 kg or 50 kg PP woven bags
Moisture-resistant inner liners
Neutral labeling or customer-approved designs
Containerized sea freight loading
These measures help maintain fertilizer quality during long-distance shipment from China to Vietnam.
Q1: Can Chinese manufacturers supply customized NPK ratios?
Yes. Most manufacturers can adjust nutrient ratios according to crop and soil requirements.
Q2: Is roller granule fertilizer suitable for Vietnam’s humid climate?
Low moisture content and compact granules help reduce caking during storage and transport.
Q3: What is the typical production lead time?
Lead time varies by formulation and order size, but roller granulation allows relatively flexible scheduling.
Q4: Are products tested before export?
Yes. Standard quality inspections are carried out before shipment.
NPK roller granule fertilizer manufacturers in China provide stable and adaptable compound fertilizer solutions for the Vietnam market. Through controlled production processes, quality management, and export-oriented packaging, these manufacturers support Vietnam’s agricultural input supply chain.
As an export-focused supplier, Hebei Wangdalei Trading Co., LTD connects Vietnamese buyers with reliable NPK roller granule fertilizer manufacturing resources in China, ensuring products meet practical agricultural and logistical requirements.
