Quality Control

Quality is built in, not inspected in.

Four checkpoints run from the moment fabric arrives to the moment the cartons are sealed — with third-party auditors welcome at any stage.

Step 01

Incoming Material Inspection

All fabrics and materials are inspected for color, weight, and defects upon arrival.

Step 02

Inline Quality Control

Our QC team monitors production at every stage — cutting, sewing, printing, and assembly.

Step 03

Pre-Shipment Inspection

Final inspection against AQL 2.5 standard before packing and shipping.

Step 04

Third-Party Audits

We welcome and support customer-arranged third-party inspections (SGS, BV, Intertek).
