In the world of apparel manufacturing, quality defines brand reputation. At AJZ Clothing, quality control isn’t just a process—it’s a culture. With over 15 years of experience as a leading custom jacket supplier, AJZ integrates five rounds of inspection, SGS-certified testing, and AQL 2.5 standards into every stage of production.

1. The Philosophy Behind AJZ Quality

AJZ believes that every jacket leaving its factory must embody precision, durability, and consistency.
This philosophy drives the company’s five-layer quality control framework, designed to minimize defects and deliver superior products that meet international standards.

“We understand that every stitch represents our client’s reputation,” says the AJZ QA Director.
“That’s why we’ve built a system where no product leaves our floor without passing multiple checks.”

2. The 5-Round Quality Inspection System

Stage 1: Raw Material Inspection

All incoming fabrics, trims, and accessories undergo visual and physical testing. Parameters include:

•  Fabric GSM & shrinkage
•  Color fastness
•  Tear and tensile strength
• Zipper and button functionality

Stage 2: Cutting Quality Audit

Before sewing begins, each fabric batch is verified for pattern accuracy and grain alignment.Digital cutting ensures that every panel fits perfectly, reducing material waste and improving fit precision.

Stage 3: In-Process Quality Control (IPQC)

During production, line inspectors check every major seam, pocket, and zipper.
AJZ uses AQL 2.5 sampling standards—accepted quality level—to determine defect tolerance. This proactive approach catches issues before they reach final assembly.

Stage 4: Final QC Inspection

Each jacket is thoroughly checked for:

• Stitch density (SPI > 10)
• Label and branding accuracy
• Functional tests (zippers, buttons, snaps
• Appearance & packaging compliance

Every approved batch receives an SGS quality certificate, ensuring compliance with global import standards.

Stage 5: Random Pre-Shipment Inspection

Before shipment, AJZ’s independent QA team randomly selects finished goods from packed cartons. These products are re-checked to ensure consistency between bulk and approved samples.

3. Why AQL 2.5 & SGS Matter

AQL (Acceptable Quality Limit) defines how many defects are acceptable in a given sample size.
At AJZ, the AQL 2.5 standard means that less than 2.5% of items in any batch can have minor defects—significantly stricter than industry averages.

Meanwhile, SGS testing guarantees that all jackets meet safety, durability, and performance benchmarks required by global retail and outdoor brands.

4. Real-World Impact: Reliability That Builds Brands

For global clients, AJZ’s rigorous process means fewer product returns, lower warranty costs, and higher customer satisfaction.
Whether producing windbreakers, puffer jackets, or ski outerwear, the brand’s strict QC process ensures every piece meets both technical and aesthetic standards.

“Our customers trust AJZ because our jackets perform exactly as expected,” adds the QA Director.
“That reliability is what turns first-time buyers into long-term partners.”
