When it comes to sourcing chemicals for industrial use, one of the most frequently searched terms is “caustic soda price per kg.” Whether you’re buying in small quantities or sourcing bulk shipments for manufacturing, understanding the factors that influence the cost of caustic soda is essential.

What Is Caustic Soda?

Caustic soda, chemically known as sodium hydroxide (NaOH), is a strong alkali widely used in:

• Chemical manufacturing
• Pulp and paper production
• Water treatment
• Textile processing
• Soap and detergent manufacturing
• Oil refining and food processing (in regulated forms)

Available in flakes, pearls, and solutions, it is typically sold by weight — most often per kilogram or per metric ton.

What Is the Price of Caustic Soda per Kg?

The caustic soda price per kg can vary depending on:

• Purity level (≥98% flakes are standard for industrial use)
• Form (flakes are typically more stable and easier to export than liquid NaOH)
• Packaging (25 kg bags, jumbo bags, or palletized options)
• Order volume (wholesale vs. retail)
• Country of origin and shipping terms (EXW, FOB, CIF)

On average, the international price ranges from $0.40 to $0.80 USD per kg, depending on the region and quantity.

Key Factors That Affect Caustic Soda Price

1. Raw Material and Energy Costs

Sodium hydroxide is often produced using the chlor-alkali process, which is energy-intensive. Fluctuations in electricity costs directly affect pricing.

2. Global Demand and Market Trends

High demand in sectors like textiles, food processing, and alumina refining can lead to temporary price hikes.

3. Shipping and Logistics

International freight rates, availability of containers, and customs duties influence landed costs.

4. Purity and Certification

Food-grade or pharmaceutical-grade NaOH is more expensive than general industrial grades.

5. Export Restrictions and Regional Supply

Some countries apply export controls on caustic soda due to its hazardous nature, affecting global availability.

Regional Price Comparison: Where Is Caustic Soda Cheaper?

The price of caustic soda per kg varies widely across regions. For example:

• Middle East: Known for competitive prices due to low energy costs and proximity to raw materials
• Southeast Asia: Moderate pricing but rising demand pushes prices up during peak seasons
• Europe: Higher due to stricter regulations and logistics
• Africa: Often imports from the Middle East or India, with additional shipping costs
