At Sikder Enterprise, quality control is engineered into every stage from raw yarn spinning and 4-point fabric inspection to in-line roving audits and final AQL 1.5/2.5 pre-shipment clearance.
Rigorous Quality Standards Built on Data & Verification
Our quality assurance protocols mirror the stringent testing criteria used by leading European and American fashion retailers.
Our 5-Stage Total Quality Management (TQM) Pipeline
From raw yarn spinning through cut panels and final cartonization, every piece passes through rigorous testing gates to guarantee zero shipment surprises.
Raw Material & Fabric Inspection (4-Point System)
Before a single roll enters the cutting room, it is examined on an illuminated fabric inspection rolling machine. Every defect is flagged with penalty points according to ASTM D5430.
Cutting Room Relaxation & Pattern Audit
Tension-free spreading is vital for knitwear. All knitted fabric rolls are relaxed for 24 hours on spreading tables to allow natural loop recovery before pattern cutting begins.
In-Line Sewing Quality Control (Traffic Light System)
Independent roving QC inspectors audit every operator on our 12 assembly lines every hour. Each workstation displays a real-time Traffic Light card (Green: Pass, Yellow: Warning, Red: Line Pause).
End-of-Line 100% Garment Inspection & Trimming
Every single produced garment is inspected by trim checkers on well-illuminated tables. Thread trimmers remove loose thread ends, and garments are scrutinized before moving to pressing.
Pre-Shipment Final Audit (AQL 1.5 / 2.5 Standard)
Our internal Quality Assurance department operates completely independently from the production team. Final audits simulate third-party audits (SGS, Intertek, Bureau Veritas) to guarantee container pass rates.
In-House Physical & Chemical Testing Parameters
Our in-house fabric and garment testing laboratory operates calibrated equipment compliant with ISO, AATCC, and ASTM test methods. Every batch receives an authenticated internal test certificate.

- Broken needle fragments or metallic wire inside garment
- Missing mandatory care, fiber composition, or country-of-origin label
- Sharp rivets, unfinished wire edges, or loose choking hazards on infant wear
- Mold, mildew, insect contamination, or dampness inside master export carton
- Chemical odor or forbidden azo dye detection
Major Defects
Functional, dimensional, or noticeable aesthetic flaws likely to result in retail customer dissatisfaction or product return.
