MHA-Ca Supplier Audit: Questions for Feed Mills and Premix Plants

Quick answer: An MHA-Ca supplier audit should verify how the exact commercial product is identified, specified, tested, released and changed. Nutritional equivalence and formula use remain decisions for the buyer’s qualified nutrition team using verified product data.

Verify product identity and reporting basis

Ask how calcium hydroxy methionine or MHA-Ca is named across the specification, SDS, COA and label and how relevant composition or nutritional information is expressed.

Do not assume a direct one-to-one conversion to another methionine source.

Review specification and batch release control

Confirm who approves the current specification, which agreed fields appear on the COA and how the supplied lot is linked to release records.

Let the buyer’s qualified team evaluate methods, units, limits and any nutritional matrix used internally.

Examine traceability and change notification

Review how raw-material, production, testing, packaging and finished-lot records support traceability for the supplied product.

Define which source, site, method, specification, composition, carrier or packaging changes require advance notification.

Check feed-mill handling fit

Discuss physical form, flow, storage, transfer, dosing and mixing with the buyer’s actual equipment and procedures.

Where needed, qualify the material through a controlled sample or plant trial rather than relying on a sales description.

Audit document and logistics support

Confirm the current specification or TDS, SDS, batch COA and applicable trade documents available for the exact order.

Review pack, pallet, lot labelling, destination, Incoterm, lead-time assumptions and issue escalation contacts.

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.
