What this is
What is a rework instruction record?
What is a rework instruction record?
A rework instruction record is the written method for a specific already-authorized rework: what is added to what, at what rate, into which target product, how it's stored and labelled, and how the result is reinspected. It is execution detail, not the decision to permit rework.
How is it different from a rework authorization?
The authorization decides whether rework may proceed and at what quantity and outline risk. This record is issued once that decision is made, and sets out the method precisely enough that an operator does not have to improvise it.
Why does allergen status get assessed twice, once here and once at authorization?
Rework carries every allergen from its original batch into whatever it is added to, and the instruction is where the target product is actually fixed. An assessment made before that pairing is known cannot be relied on afterwards.
Scope
When is a rework instruction record required?
This record is the method that follows an authorization, and belongs at the point rework is carried out. Using it to decide whether rework should happen at all, or to record a rework never written down before the fact, documents an event rather than controls it.
Use this template when
- A rework has already been authorized and now needs a written method before anyone begins
- The target product, addition rate and storage of the rework need fixing and communicating to operators
- Allergen, food safety and foreign body risk need assessing against the specific target product
- Operators need a documented briefing rather than a verbal instruction
- Reworked product needs a reinspection result recorded against the full specification before release
Do not use it for
- Rework Authorization, the decision to permit rework at all, made before this instruction is written.
- Allergen Changeover Check, which verifies a line is clear of allergen residue between products, rather than controlling an allergen carried deliberately into a rework.
- Manufacturing First Article Inspection, which inspects the first part or pack off a setup against every specified characteristic, not a reworked batch.
- Statistical Process Capability Study, which establishes whether a process can hold a tolerance, rather than instructing a one-off correction.
- Anything outside KnowQuality, which belongs in the workspace that owns that process
Compliance mapping
Which ISO 9001 cl.8.7 requirements does this satisfy?
ISO 9001 cl.8.7 requires corrected output to be re-verified before release, but says nothing about how the method is communicated to those carrying it out. That gap is what this record closes.
| Clause | Requirement | Where it lands |
|---|---|---|
| ISO 9001 cl.8.7.1 | Correction of nonconforming output by rework, planned and controlled before it proceeds | Assessment before rework |
| ISO 9001 cl.8.5.1 | Production carried out under controlled conditions, including documented information defining the result to be achieved | The instruction |
| ISO 9001 cl.8.5.2 | Identification and traceability of outputs maintained throughout production, including corrected output | The instruction |
| ISO 9001 cl.8.7.1 | Corrected output re-verified against requirements before it is accepted | Execution and verification |
| ISO 9001 cl.10.2 | Recurring nonconformity addressed by corrective action, not by repeating the same correction | Execution and verification |
| ISO 9001 cl.8.7.2 | Documented information retained: the nonconformity, action taken, and the authority deciding the action | Header |
| ISO 9001 cl.8.6 | Product not released until conformity has been verified | Result |
What it does not cover
- Rework Authorization, the prior decision that rework may proceed at all, on a given quantity and outline level of risk.
- Allergen Changeover Check, which verifies a line is clear of allergen residue before a different product runs, not an allergen deliberately carried into a rework.
- Manufacturing First Article Inspection, which inspects the first part or pack off a new setup against every specified characteristic before the run continues.
- Statistical Process Control Chart Review, which reviews whether an ongoing process is stable and capable, not a one-off correction to a batch.
- Statistical Process Capability Study, which establishes whether a process can consistently hold its tolerance.
Global
Rework Instruction Record requirements by country
The instrument that matters most is not a general quality standard but the allergen-labelling regime, since a wrongly executed rework most often surfaces as an undeclared allergen rather than a specification miss.
FASTER Act and Food Allergen Labeling and Consumer Protection Act, alongside FDA preventive controls (21 CFR 117)
The nine major food allergens must be declared, and a preventive control managing allergen cross-contact must be documented and monitored.
A rework carrying an allergen into a product whose label doesn't declare it is a labelling violation regardless of internal authorization.
Food Information Regulations 2014, retained EU allergen rules, and BRCGS Food Safety Standard rework requirements
Allergen information must be accurate for the product as sold, and BRCGS-certified sites are audited on whether rework instructions are written, followed and traceable.
An auditor asks to see the written instruction for a specific rework event, not just the prior authorization.
ISO 9001:2015 cl.8.7 and 8.5.1, and Codex Alimentarius general principles of food hygiene
ISO requires controlled conditions and re-verification of corrected output; Codex expects reprocessing controlled so it introduces no contamination.
Neither prescribes a form, so defensibility rests on the method and risk reasoning being written down before the rework happened.
How to complete it
How to complete a rework instruction record, step by step
The instruction is only as good as the specificity it forces. A method that could apply to any rework has not controlled this one.
"Added back into production" is not a target product. The specific product the rework joins determines the allergen profile it carries, the shelf life it inherits, and the specification it must meet.
Like into like, at a stated rate, is a controllable instruction. An uncontrolled rate breaks the specification even when the rework itself was sound, since the tolerance for reworked material assumes a bounded proportion, not an operator's judgement on the day.
These risks depend on what the rework is added to, not on the rework material alone. Assessing them before the target product is fixed, or assuming the authorization's earlier assessment still applies, misses the pairing that determines the risk.
A defect reworked more than once means whatever caused it was never corrected. The record should flag repetition rather than processing each occurrence as routine, since routine handling is what lets the underlying cause go unaddressed.
What auditors find
Most common rework instruction record findings
Findings cluster around whether the method was written down before the rework, and whether allergen and traceability fields were reasoned through for the specific pairing rather than carried over from the authorization.
| Finding | Clause | What fixes it |
|---|---|---|
| Rework carried out before a written instruction existed, or on a verbal instruction only. | ISO 9001 cl.8.5.1 | Require the instruction to be signed before the rework start time recorded on the line. |
| Target product left generic, or addition rate not specified. | ISO 9001 cl.8.5.1 | Make both fields mandatory and reject generic entries such as "as before". |
| Allergen status assessed as partial or not assessed against the specific target product. | ISO 9001 cl.8.7.1 | Block the instruction until allergen status is assessed complete for the named target product. |
| Storage conditions and use-by date for held rework material not specified. | ISO 9001 cl.8.5.2 | Require both fields wherever rework is held rather than used immediately. |
| Reworked product reinspected against the original defect only, not the full specification. | ISO 9001 cl.8.7.1 | Route reinspection through the same full specification check as the original product. |
| Same defect reworked repeatedly with no corrective action raised. | ISO 9001 cl.10.2 | Flag a second occurrence and require a CAPA reference before a third rework is authorized. |
Case in point
Case in point: the rework that carried an allergen nobody checked for
A cheese processor authorized rework of an off-weight batch of plain cream cheese into a fresh batch of the same product, correctly assessed as low allergen risk since both shared the recipe. The supervisor, working from that authorization and a verbal instruction from the previous shift, applied the same rate to a different run that day: a herb and garlic variant containing celery, absent from the plain product's declaration.
No written instruction existed for that pairing, so nobody re-assessed allergen status against the actual target product. The rework was technically sound and the batch matched its own specification, but it also carried celery into a product whose label had never needed to declare it, discovered only when a customer with a celery allergy reacted.

The instruction is a single written method. What actually fails is the gap it closes: the verbal shortcut, the assumption a past pairing still applies, and repeat rework nobody flagged as a pattern.
Holds the instruction library against open authorizations, and won't treat a rework as controlled until a written instruction exists for that event.
Tracks allergen carryover across rework pairings and flags where a target product's declared allergens don't cover what a proposed rework introduces.
Watches for repeat rework of the same defect and raises it as a corrective-action candidate rather than letting each instance close as routine.

Rework Instruction Record definitions and key terms
- Rework instruction
- The written method for a specific, already-authorized rework: target product, addition rate, storage and the reinspection required.
- Allergen carryover
- Transfer of an allergen in a rework material into whatever product it is added to, regardless of whether that product's label already declares it.
- Addition rate
- The stated percentage or quantity of rework material added into a fresh batch, controlled against a specification limit.
- Held rework
- Rework material stored rather than used immediately, requiring specified storage conditions and its own use-by date.
- Repeat rework
- A second or subsequent instance of reworking the same defect, signalling the underlying process cause was not addressed.
FAQ
Frequently asked questions about rework instruction record
Why does a rework need a written instruction if it was already authorized?+
The authorization decides whether rework may happen and at roughly what risk. It does not fix the exact target product or addition rate, and both determine the allergen and specification outcome. The instruction is where that specificity is captured, and its absence is what lets a verbal instruction substitute for control.
Does the allergen assessment from the authorization carry over to the instruction?+
Not reliably. The authorization's assessment is often made before the exact target product is fixed. The instruction reassesses allergen status against the actual pairing, since a rework low risk into one product can be high risk into another sharing the same equipment.
What counts as a verbal instruction for the purposes of this record?+
Any rework carried out on a conversation, a habit from a previous shift, or an assumption the method is the same as last time, without a completed instruction record signed before it starts. The record exists specifically to remove that route.
Why does a repeat rework of the same defect matter if each instance passes reinspection?+
Passing reinspection confirms the corrected batch is acceptable, not that the cause was fixed. A defect that keeps recurring and getting reworked is a process problem managed one batch at a time instead of corrected, and the recurrence is the signal worth acting on.
How is the reinspection after rework scoped?+
Against the full specification, not only the characteristic that originally failed. A rework can correct the original defect and introduce a different one, particularly where the addition rate or target product changes composition.
Who needs to sign this record?+
Quality, confirming the method, risk assessment and reinspection result, and typically a second signature evidencing that operators were briefed on this specific instruction rather than working from habit.
