01Direct answer
Approve the CoA against the spec, not the inbox.
To manage supplier CoA approval, match each Certificate of Analysis to the supplier, ingredient, lot, specification, test method, result, acceptance limit, receiving record, review decision, and corrective action if the document fails. A CoA should not be treated as approved just because the supplier sent it.
Supplier verification programs often rely on document review, testing, certificates, or other evidence. The useful record is the review decision: what was checked, who checked it, whether the lot passed, and what happened if it did not. HACCPlan connects CoA review to supplier files, receiving, ingredient lots, and product traceability.
Reviewer question
The reviewer wants to know whether the CoA matched the ingredient and lot, whether the result met the spec, and whether the lot was accepted before use.
02Approval workflow
The CoA fields to review.
- 01
Identity match
Supplier, product name, ingredient code, supplier lot, production date, expiry, and receiving record.
- 02
Test results
Parameter, method, unit, result, specification limit, and pass/fail status.
- 03
Document status
Issue date, lab or supplier signature, page count, certificate number, and missing fields.
- 04
Review decision
Accepted, rejected, held, needs clarification, or accepted with restriction.
- 05
Corrective action
Supplier follow-up, product hold, alternate lot, re-test, rejection, or supplier review.

Approve supplier CoAs in HACCPlan
Scan CoAs, review extracted fields, compare results to specs, hold failed lots, and save the approval decision beside the supplier file.
AI drafts fields. A human still approves or rejects the CoA.
03Why it breaks
CoA approval fails when the PDF is the whole process.
A PDF in a folder does not prove review. The lot may not match the delivery. The parameter may not match the spec. The result may be out of limit. The CoA may be for the wrong product or an old lot. Without a review record, the business cannot show how the decision was made.
The process should also prevent use before approval when approval is required. A CoA that arrives after production is a record problem and may become a product decision problem.
The approval workflow should be clear enough for receiving and production. If the CoA is missing or failed, the lot status should say hold, reject, or needs QA review. The ingredient should not move forward on assumption.
04What HACCPlan does
Turn CoAs into supplier-verification records.
HACCPlan connects CoA review to supplier management, receiving, AI scanning, lot records, and corrective actions.
- 01
AI extraction
Draft supplier, lot, parameter, result, and certificate fields from the document.
- 02
Spec comparison
Review the result against the ingredient requirement before the lot is released.
- 03
Lot status
Keep accept, hold, reject, and release decisions visible to receiving and production.
- 04
Supplier review
Use failed or late CoAs as evidence during supplier reassessment.
05Proof
Keep failed CoAs visible.
Failed or missing CoAs should not disappear after the immediate issue is handled. They are supplier performance evidence. HACCPlan keeps them tied to the supplier, ingredient, lot, corrective action, and next review date.
That history helps during supplier reassessment. One late CoA may be a mistake. Repeated late, incomplete, or failed CoAs may mean the supplier needs a tighter approval rule, added testing, or replacement.
06Implementation
Define approval before receiving.
For each CoA-required ingredient, define the required parameters, limits, reviewer, and release rule before the shipment arrives. HACCPlan can then turn the document review into a repeatable decision instead of a one-off email.
07Next step
Start with CoA-required ingredients.
List every ingredient that requires a CoA before use. For each one, define the test parameter, limit, review owner, and lot-release rule. Then use that list as the approval workflow.
Make CoA approval traceable
Create the CoA review workflow
Use HACCPlan to connect CoAs, supplier specs, receiving lots, acceptance decisions, holds, corrective actions, and supplier review.
Useful for supplier verification, inspection prep, and CoA-heavy ingredients.
