When sourcing stock lots, you must distinguish between overruns (excess production), canceled orders, and quality rejects. Always request a detailed packing list that specifies the size breakdown, color assortment, and fabric composition (e.g., 100% cotton vs. poly-cotton blends). For high-volume purchases, it is critical to verify the GSM (grams per square meter) of the fabric to ensure it meets your market's weight requirements and to check for consistent labeling if you intend to resell under specific brand regulations.
