Calcium Formate Supplier Change Control for Dry-Mix Mortar Plants

Quick answer: Treat a calcium formate supplier change as a controlled material change. Match the proposed grade to the approved specification, run side-by-side trials and define commercial-batch verification before routine release.

Open a documented change request

Record the reason for change, intended application, current approved material and proposed supplier grade.

Assign responsibilities to procurement, laboratory, production and quality teams.

Compare specifications and methods

Review the proposed specification, SDS and sample COA against the approved material item by item.

Do not treat matching headline assay as proof that test methods, moisture-related measures or process-relevant characteristics are equivalent.

Run controlled side-by-side trials

Keep binder system, other additives, water ratio, mixing, temperature, curing and test timing consistent.

Define acceptance criteria before testing and record deviations.

Verify the first commercial batch

Link the approved sample to the quoted grade, commercial lot and COA.

Check packaging, plant dosing and performance under the buyer's established process before routine approval.

Buyer checklist

• Confirm the exact product, grade, intended use and destination.
• Match physical lot, label, order and batch COA.
• Validate in the buyer's controlled process and record the result.
• Align packaging, quantity, destination, Incoterm and documents.

Frequently asked questions

Is a supplier change only a purchasing decision?

No. It is a controlled material change involving technical and quality review.

What documents start requalification?

Review the current specification or TDS, SDS and sample-lot COA.

Is matching assay enough?

No. Compare the full approved specification and test basis.

Why use a side-by-side trial?

It controls formulation and process variables while comparing materials.

Who should approve the change?

The buyer's authorized procurement, technical, production and quality functions.

Must the commercial batch be checked?

Yes. Verify that it matches the approved sample and specification.

What triggers requalification later?

Changes in grade, source, site, method, formulation or packaging may trigger review.

How can ADDEASY support evaluation?

Send the intended use, approved specification, sample need, quantity and destination.
