Uncompromising Quality at Every Step

Our 4-stage quality control system ensures that every product leaving our factory meets the highest international standards.

Our Philosophy

Quality Is Not an Afterthought

At Y&Z, quality is embedded into every stage of our manufacturing process — from raw material selection to final packaging. Our dedicated QC team of 30+ inspectors works alongside production to ensure that every piece meets our exacting standards and your brand's requirements.

QC Process

4-Stage Quality Assurance

A comprehensive quality control framework that covers every phase of production — from incoming materials to outgoing shipments.

Stage 1

IQC

Incoming Quality Control

Every batch of raw materials — leather, hardware, lining, adhesives — undergoes rigorous inspection before entering production. We verify material specifications, color consistency, tensile strength, and chemical compliance against approved standards.

Material specification verification
Color consistency testing
Tensile strength assessment
Chemical compliance (REACH/ROHS)
Hardware functionality testing
Stage 2

IPQC

In-Process Quality Control

Our quality inspectors are stationed at every critical production stage. From cutting accuracy to stitching quality, we monitor each step in real-time to catch and correct any deviations before they propagate through the production line.

Cutting precision measurement
Stitching quality inspection
Assembly alignment check
Edge finishing evaluation
Hardware installation verification
Stage 3

FQC

Final Quality Control

Before packaging, every finished product undergoes a comprehensive 30+ point inspection covering appearance, functionality, dimensions, and workmanship. Products that don't meet our standards are reworked or rejected.

30+ point appearance inspection
Zipper & closure functionality
Dimension accuracy verification
Stitching & edge quality
Logo & branding accuracy
Stage 4

OQC

Outgoing Quality Control

Final pre-shipment inspection following AQL 2.5 sampling standards. We verify packaging quality, labeling accuracy, quantity counts, and overall shipment readiness to ensure your order arrives in perfect condition.
