A factory can report that it has “produced 10,000 units” while a meaningful share of those units is being reworked, held for quality review, or discarded. For a buyer, the relevant question is not only how many units entered the line. It is how many conforming units are available for the order, what losses occurred, whether the loss is rising, and whether the remaining order can still ship in full.
A production yield scrap China supplier report reconciles the order quantity with good output, rework, scrap, quality hold, and remaining balance. It gives the buyer a factual view of production progress without requiring the supplier to disclose every internal cost or process detail. It also makes it easier to detect a defect trend before an inspection or shipment date arrives.
This guide is general sourcing guidance. It does not set an acceptable scrap percentage, prescribe accounting treatment, or replace the product’s technical specification, quality plan, or commercial agreement.
Production quantity is not shipment-ready quantity. The difference should be visible in the supplier’s report.
Agree what each quantity status means
The buyer and supplier should use the same definitions. NetSuite describes scrap as material or goods that fail quality standards and must be discarded, while noting that organizations can define the metric differently and should reach agreement before calculating it.1 That warning applies to buyer reporting as well: if one side calls reworked product “completed” and the other side counts only accepted output, the update will mislead both parties.
| Estado | Practical definition for an order update |
|---|---|
| Units started | Items introduced to the relevant production process |
| Good output | Units that meet the defined release condition for the reported stage |
| Rework | Units requiring corrective work before acceptance |
| Scrap | Units or material that cannot be accepted or recovered for the order |
| Quality hold | Units awaiting disposition or further evaluation |
| WIP | Units still moving through production and not yet accepted |
| Packed output | Accepted units packed under the correct order configuration |
| Shipment-ready quantity | Accepted and packed units available for handoff, subject to agreed checks |
Do not force a single definition onto every manufacturing process. A material-cutting operation may track loss by weight, while an assembly order may track pieces. The buyer should state the unit basis and stage of the report clearly.
Use a quantity-reconciliation table
A simple reconciliation tells the buyer whether the factory’s reported numbers add up. The exact formula may differ by process, but the report should show the relationship between units started, good output, rework, scrap, hold, and the balance still needed.
| Report field | Supplier update |
|---|---|
| PO, SKU, and revision | Exact order scope |
| Order quantity | Contracted unit quantity |
| Units started | Quantity introduced into the named process |
| Good output | Quantity accepted at the stated stage |
| Rework quantity | Quantity awaiting or undergoing corrective work |
| Scrap quantity | Quantity permanently unavailable for the order |
| Quality hold | Quantity pending a defined decision |
| Packed quantity | Quantity packed with correct components and labels |
| Shipment-ready quantity | Quantity available for inspection or cargo handoff |
| Remaining order balance | Quantity still required to meet the order |
For example, a factory may report 9,200 accepted units, 300 units in rework, 100 scrapped, and 400 still in process against a 10,000-unit order. The buyer can then ask whether the rework and WIP quantities are expected to make up the remaining 800 accepted units, whether replacement material is available, and when the final balance will be ready. A message saying “92% complete” does not provide the same decision value.
Keep rework and scrap separate
Oracle’s workstation guidance distinguishes units that fail standards but can be routed for rework from those that are scrapped because they cannot be repaired or reused.2 This separation matters for sourcing because rework can still affect delivery, quality consistency, and inspection risk, while scrap can reduce the factory’s ability to deliver the full order.
| Condition | Buyer follow-up |
|---|---|
| Reworkable defect | What corrective operation is planned and when will it be reinspected? |
| Unrecoverable scrap | What quantity is lost and how will the order balance be replaced? |
| Material loss | Is replacement material available in the correct approved specification? |
| Quality hold | What decision is pending, who owns it, and when will it be resolved? |
| Mixed-status inventory | Are accepted, held, and rejected units physically segregated? |
A reworked unit should not automatically be treated as good output. It should move to accepted output only after the factory completes the defined corrective step and relevant quality check. If the rework affects a visible finish, critical dimension, function, label, or compliance-sensitive feature, the buyer may require specific evidence or inspection attention.
Request meaningful reason categories
A “defect” column is too broad to guide action. Ask the supplier to categorize material loss, rework, or quality holds in a way that fits the product and process. Oracle notes that scrap reporting can use reason codes during work execution to improve visibility and decision making.2 A buyer does not need dozens of categories, but it needs enough detail to distinguish a material issue from a machine, assembly, packing, or document issue.
| Reason category | Example buyer question |
|---|---|
| Incoming material | Did the material fail identity, dimension, appearance, or functional check? |
| Process setup | Did a line setting, fixture, or tooling issue create the loss? |
| Workmanship | Which assembly or finishing defect occurred? |
| Embalaje | Was the product acceptable but the pack-out or label incorrect? |
| Manejo de daños | At which internal transfer point did damage occur? |
| Specification conflict | Was the factory working from the wrong or unclear revision? |
| Unknown pending analysis | When will a cause and disposition be confirmed? |
Avoid using the report to assign blame before evidence exists. Its first purpose is to define the order impact and contain affected goods. Root-cause analysis and corrective action can follow when the issue is significant or recurring.
Connect yield information to delivery risk
A supplier may be able to absorb a small loss with normal overproduction, extra capacity, approved buffer material, or a planned recovery run. It may also have no practical path to replace a loss before the shipping date. The update should state which situation applies to the buyer’s order.
| Yield status | Buyer decision point |
|---|---|
| Good output exceeds required balance | Confirm pack-out and inspection readiness |
| Rework can meet balance | Confirm timing, scope, and reinspection controls |
| Scrap creates shortfall | Request replacement plan, material status, and revised timeline |
| Hold blocks shipment | Identify affected quantity and disposition deadline |
| Loss trend increases | Review process, materials, inspection, and capacity impact |
| Mixed product revisions | Quarantine until identity and disposition are documented |
NetSuite explains that scrap may arise at different production stages and that unplanned loss can indicate defects, errors, or quality issues.1 The timing is important. Scrap discovered before expensive assembly or packing may have a different recovery path from scrap discovered after a product is fully completed.
Escalate trends and major changes early
Do not wait until final inspection to discuss a growing loss. Define escalation triggers such as an unexpected scrap event, a rising defect category, a quantity shortfall, a blocked rework process, an unapproved material change, or a forecast that shipment-ready quantity will miss the required date.
| Escalation field | Required content |
|---|---|
| Affected order scope | PO, SKU, revision, and quantity |
| Actual status | Good output, rework, scrap, hold, and remaining balance |
| Defect or loss category | Clear current description and evidence available |
| Containment | How affected units are identified and segregated |
| Recovery plan | Replacement, rework, process action, and timing |
| Quality protection | Reinspection or verification before release |
| Buyer decision needed | Approval, hold, schedule change, or other action |
A factory should not silently substitute material, relax an inspection criterion, or blend held units with accepted goods to protect an output target. A transparent report gives the buyer a chance to decide the acceptable path under the product requirements.
Verify the report during inspection and pack-out
The production-yield report should be consistent with what the inspector and forwarder see. At final review, compare the accepted quantity, packed quantity, carton count, scrap or hold status, and remaining balance. If the factory reports complete quantity but the physical count or packing list does not support it, resolve the discrepancy before cargo release.
| Cross-check | What it confirms |
|---|---|
| Production report versus inspection scope | Available accepted quantity is real |
| Packed quantity versus carton count | Pack-out matches reported output |
| Hold register versus shipment list | Held units are not released by mistake |
| Rework record versus final inspection | Corrected units received required verification |
| Remaining balance versus PO | Supplier can still meet the full order |
Maintain a history that improves future orders
Keep the quantity reports with the purchase order, inspection results, corrective actions, and final shipment record. Over several orders, this creates a useful view of recurring process issues, material risks, realistic output, and whether a factory reports problems early. It should support better specifications and follow-up, not an arbitrary comparison against another product’s scrap rate.
Reconcile the order balance at every critical milestone
The factory should not wait until final packing to calculate whether it can fulfil the purchase order. Reconcile the order balance after the early run, after any significant quality hold, before final inspection, and before cargo handoff. The buyer then sees whether the available good output plus realistic recovery work is sufficient to meet the contracted quantity.
| Milestone | Quantity question |
|---|---|
| Early production | Is output trending toward the required quantity after normal process loss? |
| Mid-production | Has rework or scrap changed the remaining manufacturing need? |
| Pre-inspection | Is the stated available quantity accepted and physically present? |
| Post-inspection | Does any defect disposition change shipment-ready quantity? |
| Pre-handoff | Do packed cartons reconcile with the accepted order balance? |
When a shortfall appears, separate the immediate delivery question from the longer corrective-action question. The supplier first needs to state how it will complete the order without unapproved changes. It should then investigate why the loss occurred, preserve relevant evidence, and propose corrective action where the issue is meaningful or recurring. This sequence helps avoid a rushed “fix” that solves a quantity gap by weakening product or packaging control.
Review the reconciliation with the factory’s quality and production contacts after the order closes. Compare the original planned quantity, actual accepted output, rework, scrap, and final shipment quantity. If a recurring reason category appears, add a targeted preventive control to the next purchase-order release, such as a material check, setup confirmation, or earlier in-process inspection.
Retain the reconciliation with the final packing list and inspection outcome for future supplier performance review.
Frequently asked questions
What is a good scrap rate for a China supplier?
There is no universal answer. NetSuite notes that acceptable rates depend on production method, material, product, business goals, and industry context.1 Define the buyer’s quality requirements and use trend information to investigate unexpected loss.
Should reworked units count as completed production?
They can be reported separately as production output, but they should not be treated as accepted goods until the corrective work and relevant quality verification are complete.
Why does a buyer need scrap information if the factory delivers the full quantity?
Loss can affect delivery risk, replacement material needs, quality consistency, and the reliability of future production commitments. It may also reveal a recurring issue that should be addressed before it reaches the customer.
Report usable output, not only units started
A reliable production yield scrap China supplier report reconciles the order with accepted output, rework, scrap, quality hold, packed goods, and shipment-ready quantity. It separates a recoverable rework path from permanent loss and connects factory output to the buyer’s inspection and logistics decisions.
Before the next production order, agree a concise reconciliation template and define the status terms with the factory. Supplier Ally can help buyers organize supplier quantity reporting, factory evidence, inspection checks, and recovery follow-up so production progress reflects goods that can actually be shipped.
