Start with one identifiable quotation
Ask for the legal supplier name, product family, exact grade, physical form, quoted net mass and proposed shipment terms. Use this identity across the quotation, sample label and technical documents. If the names differ, ask for a written explanation before accepting the set as one product.
Check document number, revision or issue date, issuing party and release status. A filename containing “latest” is not proof of a current approved revision. A brochure is useful for navigation, but it should not silently replace the document for the sold grade.
Separate the documents by job
| Document | Question to resolve |
|---|---|
| TDS | Which grade and revision does it describe? Which properties are indicative, specified or application-dependent? |
| SDS | Does the supplier confirm a current safety document for the named product and destination requirements? Refer handling and transport questions to the responsible specialist. |
| Batch COA | Does it identify the actual lot, specification limits, measured values, methods, dates and authorized release? |
| Application report | Can the tested sample, materials, dose basis, methods and results be traced? What differs from the intended use? |
| Company certificate | Which legal entity and management-system scope are covered? It is not evidence that this PCE grade passes your application requirements. |
These are buyer document checks. They do not certify compliance or replace destination-specific review. Ask the supplier to resolve unavailable or mismatched files explicitly.
Do not compare numbers without their basis
For any dosage percentage, identify the denominator and whether the numerator is supplied product or dry solids. Ask whether declared solids is a specification, a batch measurement or an indicative value, and what method is used. Do not equate total dried residue with active polymer content unless the supplier establishes that relationship.
For density, pH and other reported properties, request the applicable method and conditions before judging an apparent difference. A number outside context may reflect a different method or grade rather than a defective shipment. Use the dose-basis guide for units, not to supply missing technical facts.
Read a performance report as a scoped result
Ask which reference mix, materials, addition basis, measurement ages and acceptance criteria were used. Keep a historical third-party report attached to the tested sample. Do not generalize it to every current grade or shipment.
The published 2024 report retains its tested-sample scope. Current grade evidence must be requested separately. NRMCA’s laboratory testing overview also distinguishes fresh-concrete checks from strength and other tests; one result cannot stand in for every purchase requirement.
Build a concise sample and quote request
State application, binder and other admixture identities, target outcome, evaluation plan, sample quantity, estimated annual demand and delivery destination. Request current grade TDS/SDS availability, a representative COA clearly labelled as an example, and order-specific COA confirmation when the shipment lot is assigned.
Add net package mass, packaging and labelling preference, quote validity, lead time, freight/tax basis and payment terms. If documents are not released yet, keep that condition in the purchase review; do not represent an empty template as a completed batch record.
Use the evidence library to see what is public and what is available by request. HFC-1001 has a separate grade-specific procurement checklist covering its supplied-document questions. A generic checklist does not resolve those questions automatically.
Prepare your enquiry
Exact grade, application, requested document revisions, sample and annual quantity, packaging preference and destination.
Request the exact grade, current document availability, sample terms, net package mass, quotation validity and delivery terms. Suitability and performance remain subject to applicable documents and agreed evaluation.
