Change Control and Notification
What happens when a specification, process or packing detail changes: we notify you immediately rather than letting you find it at goods-in, and the batch record stays traceable.
Published · Updated
Short answer
If the specification, production process or packing changes in a way that affects what you receive, we tell you immediately — you should not discover it from a goods-in result. That is the commitment; the mechanics of it are worth fixing at qualification rather than assuming, so agree the named recipient and the route with us before the first order. Each shipment continues to carry its own COA, and every bag remains traceable to a production lot, so a change can be tied to the exact batch where it took effect.
What we commit to, and what carries the evidence
Each figure on this table states its basis. Read the full rule on the technical index.
| Property | Value | Basis |
|---|---|---|
| Trigger for notification | A change to specification, production process or packing that affects what you receive | Stated policy |
| Timing | Immediately — not batched into a later shipment or a periodic review | Stated policy |
| Named recipient and route | Agreed with you at qualificationWe do not assume a default contact; nominate the person your quality system expects to be told. | On request |
| Per-shipment record | Certificate of Analysis reporting that batch's measured values | Batch COA |
| Tying a change to a batch | Raw material lot → production lot → finished bag | Published specification |
Why the unnotified change is the one that costs money
A supplier change that is announced is a scheduling problem: you re-run the qualification, adjust the formulation if needed, and move on. The same change discovered at goods-in — or worse, from a customer complaint two months later — is an investigation, a quarantine and a re-validation, and it usually arrives at the least convenient moment. The cost difference between the two is almost entirely a function of when you were told.
This is why change notification is qualified alongside specification and documents rather than after them. A supplier who meets specification but changes it quietly has not met the requirement, because your quality system depends on knowing the material is the same one you approved.
Fix the mechanics before the first order, not after a change
The commitment above is ours. The half that has to be agreed is yours: who exactly is told, and by what route. Quality systems differ — some want the notification to reach a named quality contact rather than the buyer, some require it in writing against a change-request reference, some want a defined lead time before the affected material ships.
Raise those at qualification and they cost one email. Raising them at the moment a change happens means negotiating the process and handling the change at the same time, which is when notifications get missed.
What a notification should let you do
A useful notification identifies what changed, when it takes effect, and which batches it affects. The last part is what makes it actionable: with batch traceability from raw-material lot to finished bag, the boundary between pre-change and post-change material is a specific batch number rather than an approximate date.
From there the comparison is the normal one — request the COA for a batch on each side of the change and compare the same indicators. If the change does not move the values your process depends on, the re-qualification is short. If it does, you found out before the material entered production rather than after.
How to verify this yourself
- Nominate the named recipient for change notifications at qualification, and state the route your quality system expects.
- Ask whether your system needs a defined lead time before affected material ships, and agree it in writing rather than assuming it.
- When notified, request the batch number at which the change takes effect so pre- and post-change material can be separated.
- Compare COAs for a batch on each side of the change against the indicators your process actually depends on.
What this page does not claim
- This page states our notification commitment; it is not itself a contractual change-control agreement. Where your quality system requires one, raise it at qualification so it can be agreed in writing.
- The recipient and route are deliberately not stated as a default — they are agreed per account, because assuming a contact is how a notification goes to the wrong person.
- Notification tells you a change occurred and which batches carry it; it does not substitute for your own re-qualification.
