Standard Packaging: Standard packaging refers to the minimum packaging quantity obtained from the manufacturer/distributor. Therefore, the minimum order quantity may be less than the manufacturer's standard packaging quantity. When products are broken down into smaller quantities, the packaging type (i.e., reel, tube, tray) may change, subject to actual packaging delivery.
