Quality Control (QC)
The systematic process of inspecting garments during and after production to ensure they meet specified standards before shipment to customers.

What is Quality Control (QC)?
Quality Control (QC) in fashion manufacturing is the set of processes used to verify that finished garments meet predefined quality standards across construction, materials, measurements, and appearance. Effective QC protects brand reputation, reduces returns, and builds manufacturer accountability.
Types of QC inspections:
1. Pre-Production (PP) Inspection:
- Verifies materials match approved samples
- Checks trim and accessories quality
- Confirms measurements on PP sample
- Approval gate before bulk production starts
2. During Production (DPI/DUPRO):
- Inspection when 20–30% of production is complete
- Identifies issues early — time to correct
- Checks workmanship and construction
- Verifies measurement conformance
3. Final Random Inspection (FRI/AQL):
- Conducted when 100% of goods are packed
- Random sampling based on AQL (Acceptable Quality Level)
- Most common third-party inspection
- Go/No-Go decision before shipment
AQL (Acceptable Quality Level):
AQL defines the maximum acceptable defect rate. Common levels:
- AQL 1.5: Tightest (luxury, technical garments)
- AQL 2.5: Most common (standard fashion)
- AQL 4.0: Looser (basics, low-cost production)
Defect classification:
- Critical: Safety issues (sharp objects, toxic materials)
- Major: Functional or highly visible defects
- Minor: Small imperfections, unlikely to affect sale
Why This Matters for Fashion Entrepreneurs
QC is not optional — it is an investment that protects your brand, your customer relationships, and your margins. Every garment returned or refunded costs 3–5× its production cost in lost revenue and brand damage.
QC for emerging brands:
- Start with self-inspection using an AQL checklist
- Take photographs at each stage as documentation
- Build a "golden sample" — the approved reference garment kept for comparison
- As you scale, hire a third-party QC agent (₹5,000–15,000 per inspection day)
What to inspect:
- Measurements (±0.5cm for most points)
- Seam allowances and stitch density
- Thread tension and finish
- Colour matching to approved standard
- Trim placement and attachment
- Label placement and legibility
- Packaging and presentation
Sourcing Guide
Third-party QC in India:
Major QC agencies:
- SGS India (global leader)
- Bureau Veritas
- Intertek
- QIMA (previously AsiaInspection)
- TUV SUD
- Local options: FashionQC, InspectAR
QC inspection costs:
- Per inspection day: $200–400 (third-party agencies)
- In India for domestic: ₹5,000–15,000 per day
- Online/virtual inspection: ₹2,000–5,000 per session
Building internal QC capability:
- Develop a QC checklist specific to your products
- Invest in measuring tools (tape, rulers, defect light)
- Train production managers on your standards
- Document and photograph defects for supplier feedback
Pricing & Costs
QC investment vs. the cost of not doing QC:
QC costs:
- Third-party inspection: ₹8,000–15,000 per inspection day
- In-house QC checker: ₹15,000–25,000/month
- Quality testing (lab): ₹3,000–10,000 per test
Cost of poor QC:
- Returns and replacements: 30–100% of production cost
- Customer service: ₹500–2,000 per complaint handled
- Reputation damage: Difficult to quantify, potentially fatal to brand
- Remaking/reworking garments: 20–40% of production cost
Rule of thumb:
Invest 2–5% of production cost in QC. It will save 10–20% in defect costs.
Frequently Asked Questions
AQL (Acceptable Quality Level) is a statistical sampling method to decide whether to accept or reject a production batch. You select a random sample from your order based on the total quantity and your AQL level. Most fashion brands use AQL 2.5, meaning in the worst case, 2.5% of the batch may have major defects. Look up AQL tables (freely available online) to find your sample size and acceptance/rejection numbers.
For early-stage brands with small orders (<200 pieces per style), self-inspection with a good checklist is adequate. As you scale beyond 200–500 pieces, third-party QC becomes essential — you need objective eyes, documented reports, and the leverage that comes from a formal inspection process. For export orders, buyers almost always require third-party QC before shipment.
A golden sample (also called a sealed sample or reference sample) is the approved pre-production sample that becomes the absolute quality reference for bulk production. It is physically kept — often with an official sticker/tag — by both the brand and the factory. All QC inspections compare bulk garments against this reference. Without a golden sample, QC inspections lack an objective standard.
