Sourcing caustic soda flakes (sodium hydroxide – NaOH) for industrial use requires more than finding the lowest price. If not done carefully, it can result in product failure, customs delays, or even safety issues. This guide explains the most common mistakes buyers make when sourcing caustic soda flakes—and how to avoid them.

Failing to Confirm Product Purity

Industrial applications require high-purity sodium hydroxide. Using lower-grade products may affect performance or cause compliance issues.

Avoid this:
Always request a Certificate of Analysis (COA) to confirm the NaOH content is ≥98%.

Prioritizing Low Prices Over Supplier Reliability

Choosing the cheapest supplier often leads to quality compromises, delayed shipments, or incomplete documentation.

Avoid this:
Vet suppliers based on reputation, export experience, packaging standards, and after-sales support.

Neglecting Moisture-Resistant Packaging

Caustic soda flakes are highly hygroscopic. Exposure to moisture during transport can ruin the product.

Avoid this:
Request 25 kg double-layer PP bags or jumbo bags, and ensure palletization and shrink-wrapping for international shipping.

Misunderstanding Incoterms and Shipping Responsibilities

Incorrect shipping terms can result in unexpected logistics issues or extra costs at the port.

Avoid this:
Clarify and confirm Incoterms (EXW, FOB, CIF, etc.) based on your logistical preferences and capabilities.

Overlooking Export Documentation

Missing or incomplete documents can delay customs clearance or cause legal issues.

Avoid this:
Ensure the supplier provides all key documents:

• COA
• SDS / MSDS
• Commercial invoice
• Packing list
• Bill of lading
• Certificate of origin (if needed)

Ignoring Safety and Handling Protocols

Caustic soda is corrosive and must be handled with care during unloading, storage, and use.

Avoid this:
Use proper PPE (gloves, goggles, apron) and follow handling instructions as per the SDS.

Sourcing from Exporters Without Proven Experience

Some suppliers offer attractive prices but lack international shipping experience or compliance knowledge.

Avoid this:
Work with trusted exporters like CausticSodaIran.ir, a subsidiary of Shetab Gostar Nadin Trading Co., with experience in global delivery and chemical compliance.

Conclusion

Choosing the right supplier and asking the right questions is key to successfully sourcing caustic soda flakes. Avoiding these common mistakes helps ensure smooth operations, compliance, and long-term reliability.
