Quality Control & Assurance
The quality framework applied across every stage of garment manufacturing, from raw material receipt through to finished-goods approval, product safety governance, and structured risk analysis — combining in-house testing with third-party laboratory verification where mandated by buyer requirements.
Framework
The seven-point QC & risk framework
A multi-tier quality control framework built to manage risk, verify specifications, and enforce standards from raw input through to final shipping clearance.
Raw material QC
GSM, weave/knit construction, shrinkage, colour fastness (grade 3-4 min), 4-point defect grading & chemical compliance, before any material is cleared for cutting.
In-process QC
Cutting (24hr relaxation, marker ±0.3cm), sewing (SPI checks, 30-60min roaming inspection), finishing & packing checkpoints catch defects at source.
In-house laboratory
14 in-house test parameters — GSM, colour fastness, shrinkage, pilling, seam strength, pH — for rapid turnaround without production delay.
Third-party testing
Mandatory for regulated markets via SGS, Intertek, Bureau Veritas, TÜV, QIMA, UL, RSL — physical, flammability, children's safety, sustainability claims.
AQL final inspection
ANSI/ASQ Z1.4 pre-shipment gate conducted in-house on every order, with third-party inspection engaged when required by buyer specification; measurements, workmanship, packaging, labelling & documentation checked before dispatch.
Product safety protocol
100% in-house inspection on every lot, escalated to third-party testing or certification when required by buyer specification, covering CPSIA/REACH/flammability compliance, choking-hazard & drawstring checks, adverse-event monitoring, needle/broken-needle detection, and a documented recall & corrective-action procedure.
Product risk analysis
Pre-production risk assessment spanning fabric (shrinkage, colour fastness, GSM variation, chemical compliance), construction (seam strength, SPI consistency, trim/accessory failure, measurement deviation), and wash process (shrinkage, shade variation, strength degradation, hardware corrosion), flagging failure points before they reach production.
Acceptance
Defect classification & AQL thresholds
Clear categorization standards for evaluating defect severity and determining order acceptance.
0%
Critical
Safety or legal — zero tolerance, no exceptions
2.5
Major
Functional or aesthetic — standard pre-shipment
4.0
Minor
Appearance only — standard pre-shipment
AQL Standards & Buyer Customization
These AQL thresholds serve as a general baseline standard and are fully customizable to meet specific buyer requirements and quality protocols. Any line rejection rate exceeding 3% triggers a line stop and root-cause analysis.
