Non-Conforming Product Control
Isolation, Rework & Re-Inspection Process for Non-Conforming Products
At QINGDAO VATRAD GROUP.,LTD., a non-conforming batch never flows on. Any product or component that fails the defined acceptance criteria is identified, recorded against a Non-Conformance Report (NCR), labelled and segregated, assessed for affected scope, and dispositioned at the right authority level. Permitted rework follows controlled instructions, corrected items are re-inspected against the original acceptance criteria — including complete re-testing where required — and product ships only after authorized quality sign-off. This page presents our controlled standard under ISO 9001:2015 Clause 8.7 and the traceability evidence behind it.
Non-conforming products are never hidden, reworked informally, or released without verification at QINGDAO VATRAD GROUP.,LTD. Every identified non-conformance is recorded against the affected product, batch or component and linked to an NCR. The item is labelled (HOLD / QUARANTINE / REJECTED), physically segregated, and the affected scope is assessed by batch, material lot, process stage and document revision. Disposition is decided at the authority level matching the defect severity: Minor issues are signed off at the line level, Major issues require a QC Manager + Technical Engineer disposition with a controlled rework instruction and 100% independent re-inspection, and Critical issues require a Material Review Board decision with written customer concession where required — otherwise mandatory witnessed destruction. Reworked items are re-inspected against the original acceptance criteria, specification repairs receive a complete new stability and specification test cycle, and shipment release happens only after authorized quality sign-off. Repeated or systemic issues trigger root-cause corrective action (CAPA).

Control of Non-Conforming Products
What Happens When a Product Does Not Meet the Criteria
Products or components that do not meet the defined acceptance criteria are identified and controlled to prevent unintended use, further processing or shipment. The applicable acceptance criteria are based on the approved sample, technical specification, label artwork, bill of materials, packaging requirements and project inspection plan.
Non-conforming items are evaluated to determine the affected scope and the appropriate disposition. Depending on the issue, the item may be held, reworked under controlled instructions, replaced, rejected or otherwise handled through an approved process. Reworked or corrected items are re-inspected before release. Shipment release is permitted only after the relevant quality records are completed and the product meets the applicable acceptance criteria.
Standard 7-Step Closed-Loop
From Identify to Corrective Action
One controlled loop for every non-conformance: identify, quarantine, review, rework or replace, re-inspect, release or reject, improve.
- 01
Identify
Any identified non-conformance is recorded against the affected product, batch or component and assessed against the applicable project requirements. Detection can happen at incoming material, in-process control, final testing, packing or customer/third-party inspection.
- 02
Quarantine
Items are clearly identified and placed under controlled hold or quarantine status to prevent unintended use, further processing or shipment. HOLD / QUARANTINE / REJECTED labels carry the NCR number, SKU, batch, quantity, defect description and date.
- 03
Review
The affected scope and appropriate disposition are evaluated: single unit, shift lot, full batch or multiple batches — across shared material lots, label revisions, process stages and document revisions. Additional containment or tightened inspection is applied where required.
- 04
Rework or Replacement
Permitted rework follows approved instructions that identify the affected item, method, materials, inspection points and re-inspection requirements. Unapproved changes to the product specification, label artwork, packaging configuration or formulation are never allowed. Replacement items re-enter the applicable inspection gates.
- 05
Re-Inspection
Reworked or corrected items are re-inspected against the applicable acceptance criteria. The original failed characteristic and any related characteristics potentially affected by rework are verified before release — by independent QC, and with a complete new stability and specification test cycle for formulation repairs.
- 06
Release or Reject
Product is released only after the required re-inspection is completed and authorized quality personnel confirm conformity with the applicable project requirements. Items that cannot be brought into conformity are rejected, replaced, returned or dispositioned under controlled procedures — including witnessed physical destruction.
- 07
Corrective Action
Repeated, significant or systemic non-conformances are reviewed for root cause and corrective action (CAPA). Improvements may include updates to work instructions, material controls, inspection points, training, supplier management or document control.
Buyer Trust Pillars
Three Controls That Protect Your Brand
The process is designed around the questions overseas buyers actually ask: will problems be hidden, will rework run out of control, and will corrected batches be re-verified.
Controlled Instructions Only
Rework is strictly governed by authorized Standard Rework Instructions (SRI). Unapproved field alterations, changing specifications, or modifying formulation without written authorization is strictly prohibited.
Independent Re-Inspection
Reworked batches undergo 100% re-inspection by QA inspectors against the original acceptance criteria. Specification repairs require a brand-new, complete stability and specification test cycle — never a partial re-check.
Authorized Sign-off & Traceability
Shipment release is permitted solely after complete NCR documentation and authorized QC sign-off, with the batch status moving from HOLD to RELEASED. Systemic or repeated deviations automatically trigger root-cause CAPA workflows.
On the Factory Floor
Quarantine, Rework & Re-Inspection in Practice
Photos from our workshop in Qingdao show how non-conforming batches are physically segregated, reworked under controlled instructions and re-verified before any release decision.
Re-Inspection Gate
After rework, every batch returns to the QC test area for independent re-verification: tested by HPLC/GC and specification verification against the project-approved acceptance criteria — never a partial check.
Hold & Quarantine Station
Inspection station with QC checksheets and status labelling. Any item failing acceptance criteria is tagged HOLD / QUARANTINE, logged against an NCR and physically segregated — it cannot proceed to packing until an authorized disposition and mandatory re-inspection are completed.
Controlled Rework Station
Rework is performed at a dedicated station under an approved SRI instruction: the defect is marked, the batch remains on HOLD, and after the required stabilization period it returns to the test area for re-inspection against the original acceptance criteria.

Defect Severity & Authority
Severity Classification & Disposition Authority
Not every non-conformance is handled at the same level — disposition authority scales with defect severity, from line-level sign-off to Material Review Board and customer concession.

Zero Market Leakage
Witnessed Scrap & Destruction — Zero-Defect Anti-Diversion Protocol
Overseas brand partners need certainty that failed batches will never reach secondary retail, grey markets or e-commerce channels. Batches that cannot be brought into conformity are destroyed under a witnessed, recorded protocol:
1. Container de-identification. Under QA Director supervision, all labels, batch codes, and brand markings are removed or permanently obliterated. Container caps and seals are removed, eliminating any salvageable branded components.
2. Formulation neutralization. The non-conforming formulation is chemically neutralized per approved waste treatment protocol, rendering the active ingredient inactive and the product permanently unsuitable for any agricultural or commercial use.
3. Video & photo vault. The destruction is recorded as an uncut 1080p video with close-ups of the batch label, the de-identification process, the neutralization and the final weighed scrap pile. The video is hashed (SHA-256) and archived on a controlled server for ≥ 5 years.
4. Certified waste disposal. All formulation residue and packaging fragments are weighed, logged in the outbound ledger and transported only by qualified hazardous-waste disposal partners — no residue leaves the facility through any other channel.
Brand protection guarantee: QINGDAO VATRAD GROUP CO., LTD. guarantees 100% destruction of non-reworkable out-of-spec agrochemical products. Zero factory seconds or compromised products will ever enter secondary retail, grey markets or e-commerce channels. The Scrap & Destruction Certificate (VAT-QA-SCRAP-CERT-2026) records the product, batch, MRB conclusion, witness photos and dual sign-off by the QA Director and Plant Manager.

Quality & Defect Control FAQ for Global Buyers
How do you guarantee reworked batches meet full specification standards?+
Any reworked batch is treated as a new unit and must complete the exact same full test cycle from zero — for specification repairs, a complete stability and specification test. Independent QC inspectors, not the rework operators, perform the release validation.
Will the factory ship products with minor specification deviations without telling us?+
Never. Any deviation affecting customer-approved golden samples, label artwork, formulation or packaging requires a formal written Concession Agreement signed by the client before shipment release.
What happens if a reworked batch fails re-inspection?+
The batch is not released. It returns to a new disposition review, and if it cannot be brought into conformity it is replaced, rejected or destroyed under the witnessed scrap protocol. Repeated failure of the same defect class triggers root-cause CAPA.
Can failed batches be sold as factory seconds or through other channels?+
No. Non-reworkable out-of-spec batches are physically destroyed under the witnessed scrap protocol — labels removed, formulation neutralized, video recorded with SHA-256 hash and archived for at least 5 years. The Scrap & Destruction Certificate is signed by the QA Director and Plant Manager.
How is the affected scope assessed when a defect is found?+
The scope is reviewed by product identification, production batch, material or component batch, process stage and applicable document revision. If the same material lot, artwork revision or workstation is involved, affected products are contained and checked accordingly.
Do you need our approval before making a concession?+
Yes. Any acceptance under a documented concession that affects customer requirements — approved samples, specification, formulation, packaging or acceptance criteria — requires written customer approval before release. Without it, the product is reworked per the original requirement, replaced or rejected.
What documentation do we receive for a non-conformance?+
The NCR record covers the NCR number, detection stage, product/SKU, batch, applicable document revisions, defect description, containment, disposition, rework instruction reference, re-inspection result and release or closure approval — available per your project quality agreement.
