Direct supply solutions featuring high solubility, chemical purity, and localized configurations for industrial and agricultural application in Northern Vietnam.
As the administrative, political, and cultural heart of Vietnam, Hanoi is undergoing a profound structural economic transformation. In the agricultural sector, the Red River Delta basin—historically reliant on traditional open-field crop broadcasting—is rapidly shifting toward high-tech horticulture, urban vertical farming, and modern drip irrigation systems. Districts such as Dong Anh, Gia Lam, Ba Vi, and Me Linh are transforming into modern greenbelts. This agronomic pivot demands high-efficiency agricultural nutrients, specifically high-purity water-soluble fertilizers (WSF), to support drip fertigation, hydroponics, and targeted foliar application.
Simultaneously, Northern Vietnam has emerged as a premier global manufacturing hub. The expansion of industrial zones surrounding Hanoi (such as Thang Long Industrial Park and nearby clusters in Bac Ninh and Hung Yen) has generated unprecedented demand for industrial-grade chemical inputs. Modern manufacturing demands precise chemical reagents, including high-purity nitrates for metallurgical heat treatment, nitrites for advanced concrete set accelerators, and specialized minerals for renewable energy infrastructure. The synchronization of advanced agronomic inputs and industrial-grade minerals is vital to sustain Hanoi's growth trajectory.
"To meet both Vietnam's stringent environmental regulations (such as Ministry of Agriculture and Rural Development Decree QCVN 01-189:2019/BNNPTNT) and the precision requirements of modern micro-irrigation, fertilizer suppliers must move beyond bulk commodities. The market demands highly customized, fast-dissolving, chloride-free chemical formulations."
The global fertilizer industry is navigating a critical transition. Geopolitical disruptions and volatile natural gas pricing have underscored the importance of securing reliable supply channels for raw minerals. There is a structural global shift away from low-efficiency chemical carriers toward high-efficiency, multi-nutrient compounds. For example, Calcium Ammonium Nitrate (CAN) is increasingly replacing straight ammonium nitrate due to its safety profile, low soil acidification effect, and dual-calcium enrichment. Furthermore, the rise of Concentrated Solar Power (CSP) plants globally has forged a strong correlation between specialty nitrate fertilizers (such as Potassium Nitrate and Sodium Nitrate) and renewable energy storage solutions, where they serve as molten salt thermal storage media.
Modern agronomic research indicates that traditional nitrogen-potassium fertilizers experience up to 50% loss through leaching and volatilization. WSF series target the crop's root zone with near 95% uptake efficiency, dramatically reducing environmental runoffs.
Forward-thinking factories, such as Shanxi Vojin New Materials, are optimizing synthesis loops, minimizing greenhouse gas emissions during nitric acid production, and recovering valuable by-products to achieve a circular economic loop.

Driven since 2000, we have been committed to the entrepreneurial spirit and passion for innovation. Our team takes pride in delivering dependable products and services with a quality distinction in thermal energy storage & water-soluble fertilizer industries globally. Headquartered in the key energy and chemical production basin of Shanxi, we utilize advanced chemical synthesis routes and strict quality controls to export products that meet international standards (including REACH and ISO certifications) to over 40 countries and regions worldwide.
Connect with our Technical EngineersOur decades of chemical processing experience and refined product synthesis lines guarantee maximum yield, purity, and environmental stability.
At Shanxi Vojin New Materials, our technical department operates under strict E-E-A-T guidelines. We continuously refine the crystallization and purification processes of our nitrates series. The production of agricultural-grade potassium nitrate ($\text{KNO}_3$) and sodium nitrate ($\text{NaNO}_3$) is carried out using metathesis reactions. By reacting sodium chloride with nitric acid or through the conversion of potassium chloride with nitric acid, we obtain highly stable salts. Our crystallization processes are designed to minimize insoluble residues, ensuring that every batch of water-soluble fertilizer dissolves completely within 3 minutes in agricultural water tanks.
A primary challenge for Hanoi agriculturalists importing Chinese fertilizers is chemical purity. The accumulation of heavy metals—specifically Lead ($\text{Pb}$), Cadmium ($\text{Cd}$), and Arsenic ($\text{As}$)—in horticultural soils is heavily regulated by Vietnamese authorities. Our factory utilizes multi-stage precipitation and filtration loops during the nitric acid decomposition phase. This extra refinement step removes trace heavy metals, resulting in a product that easily complies with QCVN standards. Additionally, our chelation technology utilizes EDTA and EDDHA complexes to protect trace minerals like Iron ($\text{Fe}$), Zinc ($\text{Zn}$), and Manganese ($\text{Mn}$) from precipitation in high pH soils common to parts of the Red River Delta.
Technical Insight: Water-soluble fertilizers must maintain physical stability during ocean freight and high-humidity warehousing in Hanoi's tropical climate. Vojin New Materials employs advanced anti-caking agents and moisture-proof, heavy-duty PE/PP woven packaging to ensure free-flowing properties upon arrival.
Vietnam is leading the Southeast Asian transition toward renewable energy. Solar energy storage relies heavily on concentrated thermal energy stored in molten salts. A mixture of 60% sodium nitrate and 40% potassium nitrate forms a eutectic solar salt capable of operating at temperatures up to 565°C. By leveraging our massive chemical manufacturing base, Vojin New Materials can supply both high-volume industrial solar salts and precision crop nutrients from synchronized raw chemical lines, creating cost efficiencies that we pass directly to our clients in Hanoi.

Much of the soil in the Red River Delta, particularly fields under continuous cultivation around Hanoi, exhibits acidic tendencies. Standard Urea application releases hydrogen ions during nitrification, compounding soil acidification. Our Calcium Ammonium Nitrate (CAN) provides nitrogen in both immediately available nitrate and sustained-release ammonium forms, while depositing active calcium ions ($\text{Ca}^{2+}$). This calcium helps buffer the soil, improves structure, and prevents nutrient locking without increasing soil acidity.
Vietnam's Department of Plant Protection enforces strict limits on heavy metals (Arsenic, Lead, Cadmium, and Mercury) under Decree QCVN 01-189:2019/BNNPTNT. Our manufacturing facility in Shanxi utilizes advanced liquid phase purification and fractional crystallization. We analyze every batch via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) before dispatch, ensuring that all trace impurities are kept far below the limits required for official importation into Vietnam.
Yes. Apart from agricultural nutrient solutions, our Sodium Nitrate ($\text{NaNO}_3$) and Potassium Nitrate ($\text{KNO}_3$) are manufactured to industrial-grade specifications. They are widely utilized by manufacturing operations in Hanoi for metal heat treatment baths (as oxidizing and heat transfer agents), in glass manufacturing for optical clarification, and as chemical raw materials in local concrete admixture production.
Our typical logistics pipeline utilizes multimodal transport. Goods are dispatched from our Shanxi factory via rail or truck to the Port of Qinzhou or Tianjin, followed by sea transit to Haiphong Port. From Haiphong, containers are cleared and moved via expressways directly to Hanoi. The total transit time from order confirmation and manufacturing to arrival at your warehouse in Hanoi typically ranges between 15 to 25 days depending on shipping schedules.
Our WSF series is engineered for zero clogging. Using high-grade, fully refined raw salts, they feature a water-insoluble matter index of less than 0.1%. This ensures they dissolve completely in water without leaving residues that clog drip emitters, spray nozzles, or narrow capillary lines in hydroponic greenhouse setups.
