KOH Flakes or Solution?

KOH flakes absorb moisture easily and require moisture-resistant packaging. Liquid KOH requires compatible storage tanks, pumps and unloading equipment.

Solid potassium hydroxide is generally transported as UN 1813, while potassium hydroxide solution is generally transported as UN 1814. Buyers should always follow the current supplier SDS.

How to Choose a Supplier

Before placing an order, check the following points:

• Specification: Confirm the KOH content, product form and impurity limits.

• Documents: Request the specification sheet, SDS and a recent COA.

• Packaging: Check the inner liner, sealing, pallets and container protection.

• Origin: Confirm the actual manufacturer and country of production.

• Delivery: Compare production time, shipping time and local inventory.

• Landed cost: Include freight, dangerous-goods charges, insurance, import costs and domestic transport.

A quotation for KOH 90% flakes cannot be compared directly with a quotation for 45% solution. Buyers should compare the cost based on active KOH content and total delivered cost.
