At LoongBuy, product excellence is not an accident—it is the result of a meticulous and stringent Quality Control (QC) system. Every item undergoes a rigorous multi-stage inspection to ensure it meets our high standards for size, color, stitching, and packaging before it is approved for storage and shipment. This article provides a comprehensive breakdown of each step in this critical process.
Step 1: Initial Visual and Documentation Check
Upon receipt from manufacturing partners, each batch is first verified against the product order specifications. Inspectors confirm the SKU numbers, order quantities, and ensure all required documentation is present and accurate. This foundational step guarantees traceability and that the correct items have been received for inspection.
Step 2: Dimensional Accuracy & Size Specification Audit
Using precise measuring tools and standardized sizing charts, our QC team measures random samples from the batch. They check key dimensions such as length, width, circumference, and fit
Step 3: Color and Material Consistency Verification
Under controlled lighting conditions, inspectors compare the product's color and material to the approved physical samples and Pantone references. They check for:
- Color fastness
- Any material defects like stains, discolorations, or inconsistent textures.
- Printing or embroidery accuracy, alignment, and clarity.
Step 4: Structural Integrity and Stitching Examination
This step involves a hands-on, detailed assessment of the product's construction. For garments and bags, inspectors examine:
- Stitch density
- Seam strength and proper alignment.
- Functionality of zippers, buttons, snaps, and other hardware.
- Overall durability and finish of the item.
Step 5: Packaging and Labeling Inspection
Before an item is cleared for storage, its presentation is thoroughly reviewed. The team ensures:
- Packaging is undamaged, clean, and uses the correct materials (e.g., polybags, boxes).
- All labels
- All included accessories, manuals, or tags are present as specified.
Step 6: Final Random Sampling & Batch Approval
Following the AQL (Acceptable Quality Limit) standard, a final random sampling is conducted. A statistically significant number of units are re-checked across all previous parameters. Only after this sample passes all criteria is the entire batch given final approval.
