As a professional and influential chemical trading enterprise, DSC Company takes pride in recommending our core trading product: Sodium Hydroxide (NaOH), commonly known as Caustic Soda—a foundational inorganic chemical raw material that underpins global industrial development. With years of profound experience in international chemical trade and extensive industry resources, DSC has established long-term, stable cooperative relations with all major well-known caustic soda manufacturers in China, including Wanhua Chemical, Xinjiang Zhongtai Chemical, Shanghai Chlor-Alkali Chemical, Sanyou Chemical, Junzheng Group, and other industry leaders. Our core strength lies in integrating premium Chinese caustic soda resources to provide one-stop procurement and supply services, enabling us to deliver high-quality, cost-effective sodium hydroxide products to every corner of the world and create stable, profitable cooperation opportunities for international traders and end-users.
DSC’s Sodium Hydroxide (Caustic Soda) covers all mainstream specifications and forms in the global market, fully adhering to international standards and industry norms to ensure consistent quality across every batch. As a strong alkaline inorganic compound (CAS No.: 1310-73-2; molecular weight: 40.00), it boasts excellent chemical properties: highly soluble in water (releasing substantial heat during dissolution), with a pH value of 13-14 in a 1% aqueous solution, and inherent strong hygroscopicity and corrosiveness. We strictly control product quality through rigorous procurement inspections and full-process quality supervision: the solid caustic soda (flake and granular) we supply has a purity of 98.0% to 99.0%, meeting the first-class and superior product standards of GB 209-2018, with extremely low impurity content (sodium carbonate ≤ 0.8%, sodium chloride ≤ 0.05%, iron trioxide ≤ 0.008%); our liquid caustic soda is available in the common industrial concentrations of 32% and 50%, featuring stable performance and no sediment, making it suitable for large-scale industrial applications. As a Class 8 corrosive dangerous good, our sodium hydroxide strictly complies with international packaging, transportation, and safety regulations, with UN numbers 1823 (solid) and 1824 (solution), complete and standardized Safety Data Sheets (SDS/MSDS), and compliant packaging materials (plastic barrels, lined steel barrels, IBC containers) to prevent leakage and ensure safe trade and usage throughout the entire process.
The application scope of DSC’s Sodium Hydroxide is extremely extensive, covering nearly all major industrial fields and forming rigid market demand—this serves as the core guarantee for stable trade volume and profit margins for our cooperative partners. In the chemical industry, it acts as a core basic raw material for the production of detergents, soaps, synthetic detergents, and various chemical intermediates, while also functioning as a strong alkaline catalyst in the synthesis of fine chemicals such as pharmaceutical intermediates and dyes. In the pulp and paper industry, it is used as a cooking and bleaching agent to decompose lignin and separate cellulose, effectively improving the quality and yield of paper products. In the textile and printing and dyeing industry, it is widely utilized for cotton fabric desizing, mercerizing, and reducing dye dissolution, enhancing the luster, strength, and dyeing fastness of fibers. In the water treatment sector, it is employed to adjust water pH, neutralize acidic wastewater, and remove heavy metal ions (e.g., lead and cadmium), helping enterprises meet strict environmental emission standards.
Beyond these traditional fields, DSC’s Sodium Hydroxide also plays an irreplaceable role in high-growth industries: in the metallurgical industry, it is a key raw material for alumina extraction via the Bayer process—the core link in aluminum production—which accounts for a significant proportion of global caustic soda demand; in the food industry, food-grade caustic soda (complying with FCC and EU E524 standards) is used for container cleaning, acidity adjustment, and chocolate mold release, ensuring food safety; in the pharmaceutical and cosmetics industry, it serves as a pH regulator and saponifying agent, widely applied in the production of medicines and daily chemical products; in the energy and environmental protection sector, it acts as a catalyst for biodiesel production and is used for flue gas desulfurization in coal-fired power plants to reduce acid rain formation. This diverse and rigid application scenario ensures that DSC’s sodium hydroxide maintains stable global market demand, effectively reducing trade risks for our cooperative partners.
DSC’s core competitive advantage in global sodium hydroxide trade lies in our strong resource integration capabilities, mature global supply chain system, and professional one-stop services. Unlike ordinary trading companies, DSC maintains in-depth cooperation with all major Chinese caustic soda brands—including industry leaders such as Wanhua Chemical, Xinjiang Zhongtai Chemical, Shanghai Chlor-Alkali Chemical, Sanyou Chemical, and Junzheng Group—enabling us to flexibly procure products of different grades, specifications, and brands based on the specific needs of international traders and end-users. Wanhua Chemical, the top sodium hydroxide producer in China with an 8.2% market share in 2025, is renowned for its high-purity products; Xinjiang Zhongtai Chemical, a leading enterprise in Northwest China, boasts large-scale production capacity and cost advantages; Shanghai Chlor-Alkali Chemical, a state-controlled listed company, enjoys superior logistics conditions and exports products extensively to the Asia Pacific and European markets. Whether you require high-purity products from industry leaders, cost-effective options from regional leading enterprises, or customized specifications to meet special application needs, DSC can fully fulfill your requirements. Leveraging China’s status as the world’s largest caustic soda producer (accounting for nearly 70% of global production capacity) and our large-scale procurement advantages, we can offer more competitive pricing, helping traders gain greater profit margins in the fiercely competitive international market.
In terms of global supply and transportation, DSC has a mature, efficient logistics and customs clearance team proficient in international dangerous goods transportation norms, such as the IMDG Code (maritime), IATA DGR (air transport), and ADR (European road transport). We provide flexible packaging and transportation solutions: solid caustic soda is packed in 25kg composite moisture-proof bags or 500/1000kg ton bags, while liquid caustic soda is transported via special corrosion-resistant tank trucks or IBC containers—strictly avoiding the use of aluminum, zinc, and glass containers, which are incompatible with sodium hydroxide. We cooperate with well-known international logistics companies to ensure goods are delivered safely and on time to major global markets, including Southeast Asia, Europe, North America, Africa, and Central Asia—a fast-growing market for Chinese caustic soda in recent years. Additionally, we are well-versed in the HS code 2815110000 for solid sodium hydroxide and relevant export regulations, ensuring smooth customs clearance in various countries and regions.
To eliminate all concerns for international traders, DSC provides comprehensive one-stop services throughout the entire trade process. Our professional quality inspection team conducts strict sampling inspections on each batch of procured caustic soda, using advanced testing equipment to verify key indicators such as purity and impurity content, ensuring product quality meets agreed standards and international regulations (e.g., EU REACH, US TSCA, and GB 209-2018). Our professional international trade team offers full-process services, including customs clearance documentation, dangerous goods declaration, and destination country market access consultation, helping traders navigate complex international trade regulations and market access requirements seamlessly. Furthermore, we have a dedicated after-sales service team that responds promptly to product usage and quality feedback, providing professional technical guidance on safe operation and emergency handling (e.g., emergency measures for skin and eye contact) to ensure the smooth progress of cooperation.
