IN BRIEF
Make a panel issue easier to resolve
A panel nonconformity report connects the order, item and lot with the agreed requirement and the observed difference. Record the location, method, units and quantities inspected, affected and held; attach photographs and the relevant drawing or specification revision. That gives receiving, production and the supplier a common basis for deciding the next check and action.
- Identify it: order, item, batch, bundle, sheet or cut component.
- Show it: written requirement, actual observation, method and photographs.
- Count it: inspected, with the difference, uninspected and held quantities.
- Agree the next step: review, further checks, disposition and a recorded outcome.
UNDERSTAND THE DETAIL
How do you write a clear plywood quality complaint?
Use four parts: identify the material, state the agreed requirement, describe the observed difference, and request a specific review. Attach the purchase schedule or drawing revision so everyone can compare the same item. The supplier should be able to locate the material and understand the concern without reconstructing the order from separate conversations.
Start with the observation you can show. “The visible face has a split at location F2” is useful when it is accompanied by a sheet reference and a scale photograph. “The whole shipment is defective” leaves the inspection scope, requirement and next action unclear.

| Concern | Record beside the requirement | Useful follow-up |
|---|---|---|
| Thickness, size or flatness | Nominal specification, written limits, actual readings, units, locations, support and measurement conditions. | Compare methods and agree a repeat check on identified pieces. |
| Face appearance or finish | Face/back designation, retained appearance reference, viewing conditions, finish stage and numbered photographs. | Review the same face and the agreed appearance criteria. |
| Core gap or layer separation | Original sheet, exposed edge or cut location, layer concerned, dimensions of the observed feature and processing history. | Identify the feature and agree specimen locations and any testing. |
| Wetting or handling damage | Packing and bundle labels, arrival photographs, affected positions, storage history and when the condition was first seen. | Preserve the condition and review handling and exposure records. |
| Wrong identity or quantity | Item schedule, packing list, labels, counted sheets and any product or finish mismatch. | Reconcile physical material with the order before release. |
For exposed plywood edges, use the core-gap and bond-separation guide to describe the feature. Record appearance, dimensions and any bond concern in separate fields. See describing core gaps and bond separation.
CONNECT THE FINDING TO THE PANEL AND NEXT ACTION
Use the inspection record to move a panel issue forward.
A clear record helps CUZI and your receiving team discuss the same material and the practical next step. ECQA's inspection covers 100% birch plywood at 2500 × 1250 mm in 21, 24 and 30 mm. It records 80 workmanship checks, 0 critical, 0 major and 2 minor findings, with an overall PASS conclusion. Keep the overall conclusion alongside the individual observations when reviewing appearance, condition or an order follow-up.
Scroll horizontally to compare all columns.
| Check | What the report records | What to record for your material |
|---|---|---|
| 24 mm surface | Surface dirt · minor finding. | Identify the face, sheet and location; photograph the condition before any agreed cleaning. Keep the original images and the result of the agreed operation with the selected finish reference. |
| 30 mm surface | Remaining material not removed · minor finding. | Show the whole face and close-up with a scale and material ID. Agree any removal or finishing trial, then retain the outcome and the quantity covered by that action. |
| Workmanship scope | 23 / 20 / 37 panels checked at 21 / 24 / 30 mm; 80 in total. | State which item, lot and pieces your observation covers. Record your checked, affected and unchecked counts, with held/released identities separately. |
| Moisture scope | 2 panels per thickness; readings 6–10%; report criterion 5–14%; Pass. | Keep receiving readings with the instrument, method, positions and material conditions. Add arrival, storage or processing history relevant to the difference. |
The report uses CP as its appearance basis. Keep your selected face/back grade, permitted repairs, visible surfaces and finished physical reference with the order. Use the appearance inspection records and dimensional measurement guide for the particular check.

| Nominal item | Ordered | Available | Unfinished | Workmanship checked |
|---|---|---|---|---|
| 21 mm all-birch | 1596 | 1596 | 0 | 23 |

| 30 mm all-birch | 2548 | 2547 | 1 | 37 |
The record totals 5520 ordered, 5518 available and 2 unfinished panels. The two unfinished panels are production-status quantities; the two minor findings are inspection observations. Keep those records separate. For your shipment, reconcile the final packing list and counted receipt by item, then identify any outstanding balance and agreed next dispatch.
Use the quantity handover schedule with pack labels, contents and gross weights. Record a transport or packing observation with the arrival photographs and material identity so the follow-up can address the affected pieces.
Carry one agreed action through to the closing record.
- Preserve the observation.
- Keep the order/item revision, lot and bundle label, numbered sheet or component, original photographs and individual readings. Identify the material held while the next check is discussed.
- Agree the next check.
- Name the pieces, method, appearance or dimensional requirement and the relevant handling/processing history. Retain the original results and add the follow-up findings with their scope.
- Record the practical arrangement.
- For an agreed cleaning, rework, replacement or return, write the exact items and quantities, operation, costs or freight arrangement, responsible contacts and planned dates.
- Close each affected quantity.
- Record the recheck or replacement receipt and each released, remaining-held or otherwise agreed quantity. Keep the outcome with the order; carry a changed construction or finish into the next selected item revision.
The incoming-panel inspection record helps organise the receiving check. Keep the selected working piece and lot file with a finished-part concern, and use the repeat-order change record for the next purchase.
Start the follow-up with the affected panel.

Add your actual order reference, observation and quantities in the message. Send label photographs, drawings and readings through your existing email conversation or info@cuzicn.com, using the same item reference. The form carries the summary; supporting files are sent by email.
Identify the material and describe what you found
Give the report a reference and revision. Record the purchase order, item code, product description, nominal thickness, sheet size, face/back, core construction and agreed requirement. Add the batch or lot code, bundle label and the sheet or component position. If a code is missing, assign a temporary identifier and photograph its relationship to the remaining pack.
CUZI supplies commercial and birch-faced plywood in 3–30 mm, with poplar, birch or eucalyptus cores, BB/CC or C/D faces and E0/E1 options. Choose the face, core, dimensions and appearance requirements together for your order.
Put the requirement and reading side by side
A clear issue note might read: “Item P4, bundle B08, sheet 6: agreed upper limit 18.3 mm; reading M06 at L2 is 18.5 mm.” That is 0.2 mm above this example’s limit. Include your own order tolerance and measuring method.
Retain the full set of readings, not just the largest value. Note the measuring instrument, resolution, calibration reference and date where available, contact arrangement, sheet support, measurement positions, operator and material condition. If two teams obtain different readings, compare those details before combining the results.
NIST’s guidance on measurement traceability explains that traceability belongs to a measurement result; calibration of an instrument alone is insufficient. The method and uncertainty also need to suit the measurement decision. Use the plywood thickness measurement plan to agree the checks that apply to your item.
A suspected cause can be listed as a question for investigation. Keep it separate from the observed condition, and retain the records that allow the explanation to be examined.
Make photographs and measurements easy to follow
Use a small, numbered set of original images. Begin with the bundle identity, move to the whole sheet or component, then show the detail and measurement location. Include a scale where it helps. Keep the original files as well as any annotated copies so the reviewer can see both the condition and your explanation.
Scroll horizontally to compare all columns.
| Record | What to include | How to connect it |
|---|---|---|
| Label and packing | Readable item/batch/bundle label, pack position and relevant wrapping or damage. | Use the same bundle code in the report and packing-list extract. |
| Sheet or component overview | Face/back, orientation, temporary sheet ID and the location of the concern. | Mark F2, L2 or another location that also appears in the close-up. |
| Detail with scale | Feature in focus, suitable lighting, scale and an unobstructed view. | Caption the image with sheet, location, date and observed feature. |
| Measurement record | Readings, units, instrument/method, measuring position and relevant conditions. | Link reading M06 to the same sheet and location shown in the images. |
Use clear file names such as P4-B08-S06-L2-overview and P4-B08-S06-M06-reading. Mark the face and orientation. For colour or finish, photograph the reference sample in comparable lighting and keep it available for a physical comparison.
If photos leave questions, arrange a sample or joint inspection with the supplier. Agree which piece to retain and how to send it, and label any test results with the sample and method.
Count inspected, uninspected and held material separately
State the population being discussed: one item, one lot, one bundle or several identified packs. Record how many pieces were checked, how they were chosen, how many showed the recorded difference and how many remain uninspected. Preserve the individual results so the totals can be reconciled.
Held means material is waiting for a decision. List the affected sheets, the checks still needed and who can release them. The held quantity may include checked and unchecked sheets.
Count whole sheets and cut parts separately. Link each part to its source sheet, and record the sheets used and offcuts kept for review so the material is counted once.
Agree which additional sheets to check and what you need to learn about the affected item. The sampling and acceptance guide helps plan those checks before deciding how to handle the shipment.
WORKED BUYING EXAMPLE
Example: a dimensional difference found during receiving
Worked issue-report example: replace the quantities and limits with your order and inspection records.
An identified item contains 60 sheets. The first check covers 12 identified sheets: 3 exceed the written limit, 9 are within that one dimensional check, and 48 are uninspected. The buyer holds all 60 while the review and further checks are agreed.
Three of the twelve checked sheets differ from the requirement: 25% of the checked sample. Record the other 48 sheets as unchecked and agree further sampling before assessing the full 60-sheet item.
Scroll horizontally to compare all columns.
| Stage | Checked results | Uninspected balance | Disposition record |
|---|---|---|---|
| First check | 12 checked = 3 with the difference + 9 within this check. | 48 uninspected. 12 + 48 = 60. | 60 held. This overlaps the inspection categories. |
| Additional check | 24 more checked = 4 with the difference + 20 within this check. | 24 remain uninspected. | Keep the agreed hold unless a documented decision changes it. |
| Combined record | 36 checked = 7 with the difference + 29 within this check. | 36 + 24 = 60. Identify the 24 still pending. | Record the held identities separately from these totals. |
| Next review | Retain all 36 sheet results, locations and method details. | Agree the scope and method for the remaining material. | State the owner, agreed action and exact quantity covered. |
What this means for the order
The updated record is “7 differences in 36 checked sheets; 24 unchecked.” Of the checked sheets, 29 meet this dimensional requirement. Review any remaining checks before releasing them, and keep the 60-sheet hold status separate from the inspection count.
Keep the first record and add the second stage with its date and revision. This lets both teams distinguish new findings from a change to the counting basis.
Discuss the inspection recordWhat should be kept if a defect appears after cutting?
Retain the part identification, original sheet or bundle reference, cutting layout and relevant offcuts where practical. Record the processing sequence and where the observation appeared. Include the drawing/toolpath revision, cutting or drilling operation, tooling and setup information relevant to the feature, and any later sanding, bonding or coating.
Record the condition before and after processing where possible. Mark the cut location of any core gap and assess its effect on the component. Agree further checks if other sheets or the wider batch may be affected.
For flatness, wetting or appearance concerns, retain arrival and storage information as well. The storage, moisture and workshop handoff guide helps connect environmental history, material checks and the point of release to production.
Before further machining, repair or destructive examination, agree what needs preserving and which material can be used. Give the workshop a clear hold/release list so a useful specimen is not inadvertently finished or discarded. Structural or other performance-critical components require the appropriate responsible project review.
Send a compact review file to the supplier
For a CUZI order, email info@cuzicn.com with the order reference and affected item in the subject. Use your existing order conversation where practical. Attach the relevant requirement, packing-list extract, label photograph, overview/detail images, measurements and quantity record. A concise message with clearly named files is easier to review than several unconnected messages.
A message you can adapt
Order / item / batch / bundle / sheet or component: Agreed requirement, drawing or schedule and revision: Observed result, units, method and location: Quantity inspected / with the difference / uninspected: Quantity held and material identities / hold owner: Processing, handling and storage before the observation: Attached photographs, readings and original records: Review or next action requested / practical project need: Contact responsible for the review and follow-up:
Send the information you have and note any records to follow. Include the production or installation date you are working towards so the team can discuss priorities and next steps with you.
Use the form for the issue summary and email the supporting photos or files with the same order reference. Download the receiving worksheet for arrival checks and use the repeat-order record for agreed specification changes.
Close the loop with an agreed action and recheck
Ask for the next action your record supports: review the requirement and results, compare measurement methods, inspect more identified material, or evaluate a proposed disposition. Record the agreed scope, person responsible and next communication point. Keep ownership of the physical material clear while the technical and commercial questions are discussed.
Scroll horizontally to compare all columns.
| Action | Agree before proceeding | Keep in the closing record |
|---|---|---|
| Further inspection or test | Material/specimen IDs, selection, method, criteria, test scope and reporting responsibility. | Individual results, dates and the quantity the decision covers. |
| Rework or alternative use | Proposed operation, component suitability, trial and approval responsibility. | Agreed process, recheck outcome and released/remaining quantities. |
| Replacement or return proposal | Exact items/quantities, collection or supply arrangements, packing and commercial agreement. | Written arrangement, material movements and receipt/recheck result. |
| Final disposition | Who authorizes use, continued hold or another agreed outcome for each identity. | Decision revision, owner/date and all quantities reconciled. |
Agree any replacement, credit or return with the supplier and record the arrangement. Before closing the issue, reconcile held stock, further findings and replacement deliveries.
If the review changes the next order’s construction, grade, method or acceptance criteria, update the item schedule and retain the revised reference. That turns the completed review into a more precise repeat purchase.
Keep these details with your inquiry
- Identity: order, item, batch, bundle and sheet/component.
- Requirement: specification, limit or appearance reference and revision.
- Observation: actual feature/readings, units, location and date.
- Method: equipment/calibration, setup, conditions and individual results.
- Scope: inspected, with the difference and uninspected counts; separate hold/release identities.
- History: arrival, storage and processing information relevant to the concern.
- Action: review request, owner, further checks and final disposition.
Review the relevant product guide alongside the selected item. For appearance questions, use the face/back grade purchase schedule; for changed measurements or inspection scope, keep the agreed methods with the order.

Questions buyers ask
Should I write the suspected cause in the report?
You can record it as a question for investigation. Keep it separate from verified observations and preserve the material identity, method, photographs and process history needed to examine it.
Can affected panels be processed while the issue is discussed?
Agree whether the affected panels should be used, reworked or returned before further processing. Cutting or finishing may change the condition being assessed. Keep identified specimens and give the workshop the agreed hold/release instruction.
What should I send first with a plywood quality complaint?
Start with the order/item reference, relevant requirement and revision, observation, inspected/affected/uninspected quantities and material held. Add a label image, overview/detail photographs and readings where applicable. Identify missing information and your requested next step.
Does three differences in twelve sheets mean a 25% shipment defect rate?
The result is 25% of the twelve sheets checked. Record the other sheets as unchecked, then agree any wider sampling needed to assess the shipment.
Can I add held sheets to the inspected and uninspected totals?
No. Held is a disposition and may overlap both inspected and uninspected material. Reconcile the inspection categories to the identified quantity, then record the held/released identities separately.
What if my thickness readings differ from the supplier’s?
Compare the two measuring methods, instruments, positions, supports and material conditions. Keep both sets of readings and agree a repeat check under the same conditions.
Will photographs alone establish a bond or strength result?
Use photographs to show the feature and its location. If bond or strength needs checking, agree a suitable specimen and test method for the material and component.
Does submitting the issue form confirm a replacement or refund?
The form starts communication about your reported concern. The inspection scope, material disposition and any commercial arrangement still need agreement. Keep the agreed action and the quantity it covers in your order record.
How can a PASS inspection still record minor findings?
The overall conclusion and individual observations describe the same inspection scope. Keep the 24 mm surface dirt and 30 mm remaining-material observations with the report, then compare your material with its selected appearance reference and agree the follow-up action for the identified pieces.
Are unfinished panels the same as panels with minor findings?
They are separate records. The ECQA quantity table lists production status, while the workmanship record lists inspection observations. Reconcile ordered, available and shipped quantities against the final packing list; keep affected and held identities with the quality follow-up.
Related guidance for measurements and order follow-up
NIST’s policy on metrological traceability explains calibration references and measurement uncertainty. Use it to agree how measurements are recorded, alongside the plywood limits in your order.
