Sodium Hydroxide Price per kg | Wholesale Bulk Supply

Pricing Structure by Quantity & Form

• Factors Influencing Price per kg

  • Assay Purity & Chemical Grade: Higher purity grades (≥99% assay membrane-cell quality vs. lower-grade 96% industrial technical quality) command a slight price premium. This cost differential stems from the additional refining, filtration, and precision electrolytic processing steps required to minimize trace inorganic contaminants, heavy metals (Fe, Ni), and unwanted sodium carbonate (Na2CO3) buildup.

  • Packaging Format & Labor Requirements: The chosen packaging configuration significantly impacts unit cost per metric ton. Standard 25kg woven bags incur higher overall manufacturing, material, and bagging labor costs compared to large-scale 1-ton bulk jumbo bags (FIBCs) or direct bulk liquid tank transport, which offer superior logistical handling efficiency for high-volume consumers.

  • Freight, Logistics & Incoterms: Global logistics and international commercial terms (Incoterms like FOB, CFR, or CIF) play a decisive role in final landing costs. Because dry caustic soda is classified as a Dangerous Good (Class 8 Corrosive, UN 1823), shipping rates include mandatory hazardous material handling surcharges, specialized container securing fees, and fluctuating ocean freight tariffs during peak export seasons.

  • Raw Material & Energy Input Volatility: Industrial chlor-alkali production is an extremely energy-intensive electrochemical process (electrolysis of brine). Consequently, global electricity rates, local natural gas prices, and raw industrial salt availability directly influence baseline manufacturing expenses and seasonal price fluctuations.

  Primary Industrial Uses

  • Soap & Detergent Manufacturing: Serves as the fundamental, cost-effective alkali base chemical for large-scale saponification reactions. It chemically converts natural fats, tallow, and vegetable oils into high-grade commercial bar soaps, liquid detergents, industrial degreasers, and specialized surface cleaning agents.

  • Water & Waste Treatment: Preferred primary alkali agent across municipal water treatment plants and industrial effluent remediation facilities. It provides rapid, reliable pH neutralization for acidic process streams while effectively precipitating toxic heavy metal ions (Fe3+, Cu2+, Pb2+, Zn2+) for easy filtration, settling, and environmental discharge compliance.

  • Pulp & Paper Processing: An essential chemical reagent in the Kraft pulping process, where it acts as a primary cooking chemical to digest raw wood chips, dissolve unwanted lignin binders, and bleach paper pulp to achieve high tensile strength and brightness.

  • Textile Processing & Mercerization: Used extensively in natural and synthetic fiber processing, specifically during cotton mercerization, scouring, and dye bath preparation. It swells natural cotton fibers to significantly enhance fabric tensile strength, surface luster, dimensional stability, and dye absorption capacity.
