Caustic soda flakes (Sodium Hydroxide – NaOH) are widely used in industrial sectors such as textiles, detergents, water treatment, and aluminum production. However, buying this chemical in bulk—especially for international import—requires careful evaluation. Below are the most important things industrial buyers should know before purchasing.

1. Purity Level Matters

The standard industrial grade for caustic soda flakes is a minimum of 98% purity. This level is suitable for most industrial applications including soap manufacturing, chemical synthesis, and water treatment. Always request a Certificate of Analysis (COA) to confirm the product’s purity before purchasing.

2. Know the Packaging Options

Packaging affects both product safety and compliance. The most common options for export include 25 kg double-layer polypropylene (PP) bags, moisture-resistant and durable. For large-scale shipments, 500 kg or 1000 kg jumbo bags are also available. Ask whether the supplier can shrink-wrap pallets or customize packaging based on your requirements.

3. Documentation Is Essential

Reliable suppliers should provide full export documentation to ensure smooth customs clearance. This includes COA, Safety Data Sheet (SDS or MSDS), commercial invoice, packing list, bill of lading, and, if needed, Certificate of Origin. Incomplete paperwork can delay your shipment or cause compliance issues at the destination.

4. Work With Experienced Exporters

Choose exporters with a proven track record of international shipping. Look for those with clients in multiple regions, a professional logistics team, and clear export protocols. Iran Caustic Soda, a subsidiary of Shetab Gostar Nadin Trading Co., is one such supplier offering full-service export support and global delivery.

5. Plan for Safe Handling

As a corrosive material, caustic soda flakes must be stored in a dry, cool, and ventilated space. Ensure your team uses proper personal protective equipment (PPE) and is trained in safe handling procedures. Always refer to the SDS for specific safety measures.

6. Understand Your Shipping Terms

Choose shipping terms (Incoterms) that suit your capabilities. Options like EXW, FCA, FOB, or CIF define who is responsible for each stage of the shipment. Discuss your preferred term with your supplier early to avoid confusion.

7. Price Isn’t Everything

While pricing is important, don’t base your decision solely on cost. Quality, documentation, packaging, and supplier reliability all impact your overall procurement success. Investing in a professional and experienced exporter ensures fewer risks and long-term value.
