01
Start with process requirements. Specify soda ash type, acceptable impurities and required values, rather than only the product name.
02
The current catalogue lists light soda ash. Dense soda ash and alternative grades require a separate availability check before quotation.
03
Confirm bag material and weight, pallet requirements, unloading arrangements and storage conditions. Agree packaging with the carrier and consignee.
04
Request the current specification and a sample COA. Compare offers against the same quality requirements and the same delivery location.
