Looking for the best price of sodium hydroxide per ton? We offer direct factory-wholesale pricing on premium 99% pure sodium hydroxide (caustic soda) flakes and pearls, engineered to lower bulk production costs for chemical manufacturers, paper mills, and industrial processors.
As a high-capacity global exporter, our bulk pricing scales with your order volume—providing competitive per-ton rates for full container loads (20ft FCL, 24–26 metric tons) and multi-container contracts. Manufactured under strict ISO 9001 quality controls, our sodium hydroxide delivers optimal reactivity, fast dissolution rates, and ultra-low iron contamination.
We package our product in heavy-duty 25kg multi-wall bags (40 bags per 1-ton pallet) or 1,000kg jumbo tote containers with moisture-proof inner liners to prevent caking during sea freight. Backed by complete safety documentation (MSDS/SDS) and batch Certificates of Analysis (COA), we guarantee transparent bulk pricing with no hidden export fees. Contact our chemical sales desk today to receive an instant, up-to-date quote on the price of sodium hydroxide per ton delivered directly to your port.

Per-Ton Wholesale Cost Drivers
Tiered Bulk Volume Discounts: Procurement scale is the single largest determinant of unit cost. Purchasing in full 20-foot container loads (24–26 metric tons net weight) unlocks maximum volume discounts, significantly lowering the overall price per ton compared to partial pallet shipments or Less-than-Container Load (LCL) orders.
Direct Factory-Scale Supply: Eliminating third-party distributors, traders, and regional intermediaries allows buyers to secure transparent, mill-direct wholesale pricing per metric ton. Direct sourcing guarantees direct factory warranty, consistent quality, and lower baseline procurement overhead for large-scale industrial operations.
Optimized Freight Packaging & Payload Density: Packaging the material in standardized 1-ton unitized pallet configurations (25kg bags stacked 40 per pallet or 1-ton FIBC jumbo bags) maximizes volumetric efficiency inside standard ocean containers. This high packaging density optimizes container payload limits, driving down net ocean freight charges per metric ton.
High Chemical Assay & Reduced Freight Weight: Sourcing solid dry caustic soda with a high 99% assay purity provides significantly more active alkali per ton compared to liquid caustic soda solutions (typically 50% concentration). Purchasing dry solid material eliminates the cost of shipping inert water weight, drastically reducing total required tonnage, storage footprints, and per-unit transport expenses.
Long-Term Contract Stability: Entering into structured quarterly or annual supply agreements protects industrial buyers from spot-market price volatility. Fixed-volume commitments streamline production scheduling and supply chain logistics, securing stable baseline cost per ton over extended commercial runs.
Primary Industrial Applications
Soap & Detergent Production: Functions as the primary bulk raw alkali used to saponify animal fats, vegetable oils, and synthetic fatty acids in high-volume soap manufacturing. It enables rapid, complete triglyceride conversion in commercial bar soap lines, liquid detergent bases, and heavy-duty industrial cleaning formulations.
Pulp, Paper & Packaging Processing: Essential in Kraft pulping operations as a core cooking chemical to digest raw wood chips, break down complex lignin binders, and separate high-strength cellulose fibers required for manufacturing durable paperboard, corrugated packaging, and fine paper.
Municipal & Industrial Wastewater Treatment: Deployed at scale in municipal water purification systems and heavy industrial processing plants. It neutralizes highly acidic chemical waste streams, precise controls pH balance, and precipitates hazardous heavy metal ions (Fe3+, Cu2+, Pb2+, Zn2+) for safe filtration and environmental compliance.
Alumina Extraction & Metallurgy: Utilized extensively in the Bayer process, where concentrated caustic solutions digest crude bauxite ore under elevated temperatures and pressures to extract pure alumina (Al2O3), the fundamental chemical precursor used in aluminum metal smelting.
Chemical Manufacturing & Synthetic Precursors: Serves as a vital alkaline feedstock in synthesizing a wide array of organic and inorganic sodium compounds, superabsorbent polymers, water-soluble solvents, and agricultural chemical additives.
