Quotation field matching

Caustic soda supplier responses on one evidence basis

Quote matching lines sodium hydroxide assay, package UN marks and delivered costs onto one worksheet so two factory replies can be read together. Caustic Soda Suppliers Sourcing coordinates that worksheet. It does not run a chlor-alkali cell, approve a shipment or rank plants.

Begin with the form you already chose on the beads and liquor directory. If concentration is still undecided, leave the field empty rather than copying a brochure typical. A mill that offers 50 percent liquor in place of bulk beads must keep that offer on a separate comparison row until your technical buyer accepts the switch.

Side-by-side SDS and quotation review for caustic soda

Requirement cards we send with every caustic soda supplier RFQ

Specification block

Chemical name, CAS 1310-73-2 when known, physical form, requested assay as NaOH percent, moisture, sodium carbonate, chlorides, iron or other trace metals, and particle size for beads. Density and pH belong only when a liquor or diluted sample is actually being quoted.

Quantity and timing

Net kilograms or metric tons, sample versus production lot, requested window, and whether staggered deliveries are acceptable. MOQ, production slot and lead time remain supplier answers, not website promises.

Document block

Current safety data sheet, technical data sheet, certificate of analysis format, and any TSCA, REACH, GMP or ISO quality-system statement the buyer wants the supplier to address for this product only.

Delivered-scope block

US plant or port, packaging, labeling language, Incoterm, freight inclusion, duties and excluded services. Compare total procurement scope, not an isolated ex-works number against a delivered number.

This desk cannot invent a missing SDS, cannot convert UN 1823 solid classification into UN 1824 liquor classification, and cannot treat a related-grade CoA as evidence for the quoted lot. Qualified EHS and quality teams decide acceptance after they see the files.

SDS, TDS and CoA questions for a caustic soda supplier

Which SDS revision is attached?

Ask for issue date and product identifier. A 50 percent liquor SDS does not cover 99 percent beads. Handling, storage temperature and first-aid statements follow that file, not a generic webpage.

What does the TDS actually specify?

Typical TDS fields for this family include assay, bulk density or particle size, appearance and suggested storage. Treat typical values as discussion points until the CoA for the offered lot is available.

What must the CoA report?

Agree the analytes in advance: assay, Na2CO3, NaCl, Fe, moisture and any process-critical ions. A CoA that omits a requested analyte is an open item, not a pass.

Can transport class be inferred?

No. Packing group and UN number come from the exact SDS and destination rules. Carrier acceptance is separate from a factory quotation.

Discuss product requirements with a comparable field list

Attach unresolved moisture or iron limits. Optional budget and supplier preference can travel with the brief; they do not rank factories. After the worksheet is readable, we can request factory quotes.

Submitting this brief requests sourcing follow-up; it does not confirm stock, price, compliance or delivery. See our Privacy Policy.
