Before bulk apparel production, brands should confirm the approved sample, measurement tolerance, fabric standard, color standard, trim standard, artwork placement, label position, packaging requirements, and inspection checklist.

Important quality control points include fabric defects, color consistency, shrinkage, stitching quality, seam strength, measurement accuracy, pocket placement, zipper function, button attachment, print or embroidery quality, label placement, and final packaging.

A clear approved sample is important because it becomes the reference for bulk production. If the sample is not fully confirmed before production, the buyer and manufacturer may have different expectations about fit, color, construction, or finishing.
