A supplier emails a revised specification. Purchasing saves the attachment, the next order arrives, and production continues. Months later, someone investigating a product difference asks which specification applied to the raw material used in a particular batch.
A useful change process should make that question straightforward to answer. It should also help the team decide whether the change affects the product before the revised material moves into routine use. The practical challenge is to connect supplier information, technical assessment, physical stock and the people making decisions.
First, establish what actually changed
Keep the previous document and the revised one. Record their identifiers, issue dates, the date received and the supplier’s explanation. Ask whether the change concerns the material itself, a specification limit, a test method, a manufacturing site or a correction to the document.
These situations need different assessments. A changed limit does not necessarily mean a material’s composition has changed. Equally, an unchanged trade name does not establish that everything relevant remains the same. Obtain the facts needed to describe the difference precisely.
For EU safety documentation, the Commission’s Annex I guidance addresses raw-material identification, specifications and relevant impurity information. It also calls for effective information exchange between the responsible person and safety assessor when the safety report needs updating.1
Create one internal change reference for the review. Emails, specifications, questions and decisions can then point to the same event. Make the scope explicit, including what remains uncertain and which decisions depend on clarification from the supplier.
Route the change to the people whose decisions it affects
Assign a coordinator to keep the review moving. This person need not make every technical decision. Their role is to ensure the relevant reviewers receive the information and that the process reaches a documented outcome.
The following is a suggested allocation of review questions. Smaller companies may combine roles, while larger businesses may involve additional specialists.
| Function | Useful review question |
|---|---|
| Purchasing or supplier management | Which orders and future deliveries are affected? |
| Formulation or development | Does the change affect the intended function, amount used or process? |
| Quality | Are acceptance criteria, incoming checks or material status affected? |
| Regulatory and safety assessment | Does the product information or supporting assessment need review? |
| Manufacturing | Do instructions, handling or scheduling need adjustment? |
| Brand or customer account owner | Do claims, customer commitments or approval conditions need attention? |
Send reviewers a clear question and deadline, with the documents they need. “Please see attached” leaves responsibility ambiguous. Ask each reviewer to state their conclusion, evidence and any conditions before the revised material can be used.
Identify the formulas and stock within scope
Start with the internal raw-material identifier and the supplier’s product code. Check where that material appears in active formulas, development projects, purchase orders and available inventory. Include aliases or duplicated records if the same commercial grade has been entered more than once.
Then establish the supplier’s effective date and the first affected lot, where available. Do not assume that a document issue date is the date a revised material entered production. Ask the supplier to clarify the relationship if it is unclear.
Your review should distinguish material already received, material on order and material expected later. Determine whether existing product batches could be affected by the newly supplied information. If the scope cannot yet be established, record that uncertainty and decide how it affects incoming material and planned work.
Give each affected item a disposition or a next action. This avoids a technically complete assessment that never reaches the person preparing the next batch.
Agree the evidence needed for acceptance
Decide what work will resolve the actual question. Depending on the change, this might involve supplier clarification, document review, additional incoming checks, a formulation trial or reassessment of existing test evidence. Record the rationale for the chosen level of work.
A certificate of analysis describes results or conformance for an identified lot. Read it alongside the applicable specification and the supplier’s explanation of the change. A conforming result against a revised limit does not, on its own, show that the revision is suitable for every existing formula.
FDA’s longstanding cosmetic self-inspection checklist includes raw-material identity, lot identification and control status, as well as controls for materials that fail acceptance specifications.2 Those are useful practical references when connecting the review to physical stock; the checklist is not presented here as a new MoCRA GMP rule.
Keep “assessment complete” separate from “permitted for use.” If approval depends on an additional trial or a customer decision, make that condition visible until it is satisfied.
An illustrative changeover with two lots on site
Illustrative example: a fictional supplier revises the solids-content range for a botanical ingredient. The warehouse holds lot A under the previous specification, while lot B arrives with the revised documentation.
The team records both lots under the same change review but preserves the specification associated with each. Development assesses whether the revised range matters at the ingredient’s use level in two active formulas. Quality checks the proposed acceptance approach, and the safety assessor receives the relevant composition information.
For one formula, the reviewers conclude that the documented evidence supports use under stated conditions. For the second, a trial is needed before a decision. Purchasing and manufacturing receive the resulting instructions, including which lot and formula combinations are currently permitted.
This example does not imply that a solids-content revision always requires a trial or always changes safety. It shows how one supplier event can lead to different decisions for different uses. A single label saying “supplier approved” would not communicate those distinctions.
Close the review with evidence of implementation
The final record should state what was accepted, by whom, when and for which uses. Include any revised internal specification, instructions, assessment or customer decision. Preserve the evidence used to reach the conclusion and the records that show the change was implemented.
Keep the supplier change notice and supporting documents linked to the affected raw materials, lots, formulas, samples and batches. A colleague reviewing any of these records should be able to find the notice and the resulting decision.
Treat document availability as the foundation for the team’s review. Define separately how owners are assigned, how decisions are communicated and how use restrictions are applied in your operation.
Before closing the change, check a concrete example: can someone identify the first affected incoming lot and explain the decision for the next planned batch? If they can retrieve the supplier notice, assessment and applicable instructions from that example, the review has become part of daily work.
