Questions to confirm
Is the offered material soda ash light, soda ash dense, or both, and can you quote separately by grade?
Please confirm CAS 497-19-8, formula Na2CO3, and HS code for the exact product lot offered.
What is the guaranteed Na2CO3 content on dry basis, and can you provide a recent lot COA?
For NaCl, the page states 0.7% min but shows lower results; should this specification be 0.7% max?
Please confirm Fe, sulphate, water insoluble matter, moisture, and particle size specifications for the requested grade.
Which standard applies to the material: GB 210.1-2004 or another current standard?
What bag sizes are available for export orders, and are bags lined or moisture-resistant?
Can you provide English labels, SDS, COA, packing list, invoice, certificate of origin, and pre-shipment photos?
