Buyer-facing sourcing candidate for sodium bicarbonate offered as 99% industrial grade from China. The listing shows CAS 144-55-8 and NaHCO3 assay around 99.0-100.5%, with quoted packing of 25 kg bags. Several source fields conflict, including formula/product naming and a model reference to caustic soda flakes, so buyers should verify CAS, COA, grade, HS code, and intended export documentation before RFQ or sample approval.

Applications and sourcing options
Check whether this product fits the buyer's actual application.
Clear application, grade, package, and document notes help separate real sourcing demand from a vague price check.
Use context
Common applications
Industrial alkali applications where sodium bicarbonate grade is confirmed
Detergent, cleaning, and daily chemical formulations subject to buyer qualification
Water treatment or pH adjustment applications subject to local compliance checks
Textile, paper, adhesive, and general process chemical applications
Food, feed, or pharma-adjacent inquiries only after grade-specific certification and destination compliance review
How we compare
Sourcing options
Request sodium bicarbonate CAS 144-55-8 industrial grade 99% with full COA and SDS
Request food-grade sodium bicarbonate separately if intended for food or daily-life applications
Compare with sodium carbonate suppliers only if the actual requirement is soda ash, not sodium bicarbonate
Search separately for caustic soda flakes CAS 1310-73-2 if the buyer requirement is sodium hydroxide flakes for India
Ask for sample approval and third-party inspection before bulk shipment due to listing identity conflicts
Human review
Compliance notes
Verify product identity because the listing title says baking soda/sodium bicarbonate, CAS is 144-55-8, but the formula field states sodium carbonate and the model number says caustic soda flakes
Request current COA, SDS, TDS/specification sheet, and commercial invoice/packing list draft before shipment
Confirm whether offered grade is industrial, food, feed, or pharmaceutical; do not rely on mixed application wording without grade-specific documents
Check destination-market requirements for India or other import markets, including HS classification, labeling, and any food/feed/pharma restrictions if applicable
Confirm DG status and export classification with the supplier's SDS and freight forwarder; do not assume non-DG based only on marketplace text
Ask whether third-party inspection, pre-shipment sampling, and batch retention samples are available

Questions to confirm
Please confirm the exact product name, CAS number, formula, HS code, and grade on the COA and SDS.
Is this material sodium bicarbonate CAS 144-55-8, sodium carbonate, or caustic soda flakes? The source listing contains conflicting identifiers.
Can you provide a recent batch COA showing NaHCO3 assay, chloride, loss on drying, Pb, As, iron, whiteness, and particle size?
Is the quoted 99% material industrial grade only, or can you supply food-grade material with GB1886.2-2015 documentation?
What is the standard packing construction for 25 kg bags, and can you provide palletized export packing?
What is the MOQ, lead time, monthly available quantity, and validity of the quoted price for 25-99 tons and 100+ tons?
Can you support SGS/CCIC or buyer-appointed pre-shipment inspection?
Please confirm loading port, Incoterms available, container loading quantity, and whether ocean freight to India can be quoted.
