INSIDE OUR MULTI-STAGE QUALITY ASSURANCE PROCESS

Inside our garment quality control process: six stages, zero shortcuts

Most factories inspect at the end. We inspect at every stage — with documented standards, real numbers, and no exceptions even when deadlines are tight.

Mid-audit trigger point

In garment manufacturing, quality is easy to promise and hard to deliver consistently. The difference between a manufacturer who delivers it reliably and one who only promises it comes down to one thing: process. Here is ours — in full, with the numbers.

Our apparel quality assurance process runs across six distinct stages. Each stage has a dedicated team, a documented checklist, and a clear pass standard.

No stage signs off until the standard is met. No order ships without a clean final report. That is not marketing language — it is how we have operated since day one at our 100,000 sq. ft. facility in Howrah.

"A defect found inside our facility costs us ten minutes. A defect that reaches a customer costs us their trust — and that is not something we are willing to spend."

— Quality philosophy, Mettaloom Howrah

The six stages of our garment QA process

01 Stage One · Incoming

Raw Material Inspection

Before a single stitch is made, every incoming fabric batch is tested and inspected. We check GSM consistency, color fastness, shrinkage rate, and surface defects on every roll.

Our shrinkage tolerance is ±3%. Fabric outside that range is returned to the supplier — not compensated for in finishing, not accepted with a note. Returned.

This is the foundation. Everything downstream depends on getting it right here.

02 Stage Two · Pre-Production

Pre-Production Review

Before bulk production begins, every style goes through a structured pre-production review. The tech pack is studied in detail, approved sample measurements are verified, trims are confirmed, and the full production sequence is documented.

Most defects in bulk production traceback to something that was unclear or assumed at this stage. A size spec interpreted differently between teams. A trim approved in one colour way but procured in another.

Catching it here costs one hour. Catching it after 5,000 pieces are cut costs a week.

03 Stage Three · During Production

In-Line Inspection

This is the stage most manufacturers skip or underfund — and where most defects silently multiply.

Our QA team inspects the first output pieces within 60 minutes of production starting on any style. If something is wrong — stitch tension, seam allowance, collar placement — we stop, correct, and restart before the problem runs for hours.

Throughout production, we use statistical sampling at regular intervals. Every result is logged. Every issue is tracked until resolved. Nothing disappears into a verbal correction.

04 Stage Four · Mid-Run

Mid-Production Audit

When production reaches 30% completion, we conduct a formal mid-production audit — carried out by a senior QA officer who has not been part of the day-to-day in-line checks for that style.

Why a fresh pair of eyes? Because familiarity breeds blindness. The person who checks the same garment fifty times a day eventually stops truly seeing it. Small deviations become invisible through repetition.

The mid-audit results feed directly back into the production line as documented corrective instructions — not verbal notes, not informal fixes.

05 Stage Five · Finished Goods

Final Inspection — AQL 2.5

Our final apparel quality inspection follows the internationally recognized AQL 2.5 standard — one of the most widely used benchmarks in global garment production.

At AQL 2.5, the acceptable defect rate for major defects is 2.5% of the inspected sample. For critical defects — anything that would make a garment unsafe or unsellable — our tolerance is zero.

Every piece is checked for measurements against the spec sheet, construction quality, appearance, and finishing. Critical defects trigger immediate batch rejection. Major defects trigger rectification before re-inspection. No order moves forward without a clean report.

Packing & Shipment Verification

A perfect garment packed incorrectly is still a problem. This final stage verifies that every piece has been packed to exact brand specifications — polybag dimensions, hanger type, hang tag placement, barcode accuracy, carton labelling, and packing ratios.

We also conduct a final random pull from sealed cartons — opening them, re-inspecting pieces, and confirming the packing list matches the shipment content exactly.

This is our last opportunity to catch anything that slipped through. In our experience, it catches more than people expect.

What this means for you as a brand partner

Six stages. One promise. Zero surprises.

• →Problems are caught and resolved inside our facility — not when your shipment arrives at the warehouse

• →Full documentation at every stage — you can trace the quality journey of any order, any batch, any style

• →Consistent output across orders — our process is standardised, so your fifth order matches your first

• →Honest communication when something needs rectification — never hidden until it becomes your problem

• →A manufacturer who cares about your customer's experience as much as you do — because our reputations are connected

The part no process document can capture

The human element

Systems create consistency. People create excellence.

We can print every checklist and train every team. We do — rigorously and without exception.

But our most important quality tool is not a standard or a sampling method. It is the pride our workers take in what t hey make.

It is the cutter who pauses and re-checks her alignment because something doesn't feel quite right — even though the measurement is within tolerance. It is the finishing team member who flags a tiny collar irregularity that no protocol would have caught.

That quality of attention comes from a culture where people feel that what they make genuinely matters. We work every day to build and protect that culture. Because ultimately, every garment that leaves our building is a reflection not just of our process — but of the people behind it.

Quality is not what you say. It is what you ship.

Every manufacturer will tell you they care about quality. The words are free. What is not free is the discipline to build a six-stage inspection process — with documented standards, real numbers, and independent audits — and follow it every single day.

We share this process not to impress you, but because we believe brands deserve to know exactly how their products are made.

Come and walk our floor. Watch stage three on a live production run. Ask to see a mid-production audit report. Pull a carton and open it with us.

We are proud to show you both the process and the result.
