FAQ
If a package manufacturer receives fiberboard stock from different suppliers, must the manufacturer have each box, made from each supplier’s stock, certified?
Yes, unless it can be determined that the fiberboard stock is virtually identical and meets the criteria that has been established. For example, if different suppliers are supplying fiberboard that is virtually identical (same components, manner of construction, burst strength, Cobb rating, etc.) it would not be necessary to retest.
