What is the industry standard for overage when ordering corrugated boxes?

The industry standard for overage when ordering corrugated boxes typically ranges from 5% to 10% of the total order quantity. This overage accounts for potential defects, damage during shipping, and production variances. Customers may adjust their overage requests based on specific needs, such as anticipated spoilage or unique packaging requirements. It's always advisable to discuss overage levels with the supplier to align on expectations.
