Learn MoreFounded in 1974, Henan Yongchang Nitro Fertilizer has evolved over half a century from a localized chemical startup into a modern chemical industry leader with an annual production capacity exceeding one million metric tons.
Our integrated industrial matrix combines state-of-the-art manufacturing technologies with robust supply chain pipelines, enabling us to deliver raw chemicals and specialty formulations directly to challenging geographical markets like Lesotho.
Currently, our global distribution networks serve clients across more than 20 countries, bringing high-purity industrial salts and nitrogen-based compounds to critical projects worldwide. Our operations integrate the complete value chain: from foundational ammonia synthesis to tailored agricultural blends.
Lesotho's unique macroeconomic framework, characterized by a high-altitude landlocked geography, a thriving mining sector, massive infrastructure works under the Lesotho Highlands Water Project (LHWP), and sensitive agricultural highlands, places highly specialized demands on nitrate-based chemicals. As a critical input, nitrates serve as the baseline for explosives formulation, agricultural rejuvenation, concrete modification, and industrial textile processes.
The Letšeng, Kao, Liqhobong, and Mothae diamond mines, operating at altitudes exceeding 3,000 meters above sea level, face severe logistical and environmental challenges. Blasting in dense Kimberlite pipe formations under freezing mountain winters demands highly stable, low-water-absorbent chemical reagents. Ammonium nitrate and its derivatives, synthesized utilizing our proprietary dual-pressure nitric acid processes, ensure consistent crystallization structures. This guarantees optimal detonation velocities and minimal toxic gas release in deep-pit mining environments. Industrial-grade nitrates sourced from Yongchang undergo strict anti-caking treatments, maintaining physical integrity during transport across high-altitude roads.
The construction of the Polihali Dam and extensive transfer tunnels requires massive volumes of specialized concrete. At sub-zero winter temperatures typical of the Maloti Mountains, concrete curing is severely retarded, threatening structural deadlines. Calcium nitrate acts as a non-chloride, high-efficiency concrete setting accelerator. It promotes the early hydration of tricalcium silicate, accelerating strength development without causing steel rebar corrosion. Additionally, the anti-freeze properties of high-concentration nitrate solutions allow concrete pouring to continue in cold weather, minimizing project downtime.
Lesotho's agricultural sector struggles with soil erosion and severe acidification, particularly in the northern lowlands and mountain valleys where maize, wheat, and sorghum are cultivated. Conventional ammonium-based nitrogen fertilizers accelerate soil acidification. Yongchang's Nitro-Sulfur compound fertilizers and calcium nitrate products provide immediately plant-available nitrate-nitrogen (NO3-) combined with soluble calcium and sulfur. This formulation bypasses the acidification cycle, neutralizes soil toxicities, promotes root elongation, and improves water-use efficiency in rain-fed mountain agriculture.
Maseru is home to one of Sub-Saharan Africa's largest textile manufacturing hubs. The coloring and finishing of denim and synthetic fabrics demand high-grade sodium nitrite as a diazotization reagent and dye stabilizer. Additionally, the textile washing plants generate high-COD (Chemical Oxygen Demand) effluents. High-purity aluminum nitrate and calcium nitrate are used in wastewater treatment as coagulants and microbial odor control agents. This helps local factories comply with strict environmental discharge regulations.
Backed by our National-Level R&D Center, we continuously push the boundaries of chemical efficiency and environmental stewardship.
Implementing our "Localized Service + Global Footprint" strategy, we ensure seamless supply security across Sub-Saharan Africa. Sourcing from our main production plants, we route shipments via major maritime lanes directly to the Port of Durban, South Africa, the primary gateway to Lesotho.
From Durban, our logistics partners utilize intermodal road and rail systems traversing the Free State directly through the Maseru Bridge or Maputsoe border crossings, ensuring reliable delivery straight to your industrial facility or mining site.
Our heavy-duty, moisture-sealed packaging (PE-laminated woven bags and robust bulk containers) prevents product degradation caused by humidity and rough transport over mountain passes, maintaining original product quality upon arrival.

Under cold temperatures characteristic of Lesotho's high altitudes, standard concrete curing is slow, which can delay projects. Calcium Nitrate accelerates cement hydration without introducing chloride ions. This prevents steel rebar corrosion, ensuring structural durability for civil engineering projects like the Lesotho Highlands Water Project.
We apply high-performance anti-caking coatings to our granular and crystalline products. Additionally, we use hermetically sealed packaging—including multi-layer PE bags and water-resistant bulk jumbo bags—to prevent moisture ingress during maritime transit to the Port of Durban and subsequent truck transit to Lesotho.
Our manufacturing processes use continuous automated crystallization, controlled by advanced DCS systems. This ensures a consistent purity profile of ≥99.0% with extremely low moisture content, preventing discoloration and reaction failures in textile dye baths.
Yes. Our Nitro-Sulfur compound fertilizers provide a balanced blend of nitrate-nitrogen and plant-available sulfur. This formula delivers nutrients without accelerating soil acidification, helping to restore nutrient-depleted soil and improve crop yields.
Typically, shipping from Chinese ports (Qingdao/Tianjin) to the Port of Durban takes 25 to 30 days. Custom clearance and inland logistics to Maseru add another 7 to 10 days. We recommend placing orders 45 to 60 days before your project requirements to maintain continuous stock levels.
