Caustic soda
Sinopec Science& Tech‑Tianjin Corporation offers caustic soda, chemically sodium hydroxide, in flake form with a minimum purity of 98 % as recorded in their technical specification.

Sourcing Caustic soda from Sinopec Science& Tech-Tianjin Corporation - China Import Guide
Potential buyers should request a recent certificate of analysis confirming the 98 % minimum purity and obtain the material safety data sheet before committing to a purchase. Verifying the UN 1823 classification and ensuring that the packaging meets the destination port’s handling facilities are also essential steps.
Importers need to agree on Incoterms such as FOB Tianjin or CIF Shanghai, and clarify the lead‑time, which the supplier has not disclosed publicly. Payment arrangements, typically a confirmed letter of credit, should be aligned with any agreed inspection clauses.
To safeguard product quality, a third‑party inspection at the loading port can be arranged, and the shipment should include proper hazard labels, the MSDS and the UN 1823 documentation. These measures help meet both regulatory requirements and the buyer’s internal quality standards.
