Frequently asked questions
Do you carry my exact size, like 10 x 10 x 4?
We stock over 1,300 corrugated box sizes, from 4" x 4" x 4" up to 48" x 48" x 48" and beyond. Send us your dimensions and we will confirm availability. If we do not stock it, we can make it as a custom size.
Is there a minimum order?
Stock boxes are sold in bundle and pallet quantities, so the count depends on the size. Custom box runs start at 100 pieces. Ask us and we will confirm the bundle count for your size.
How is pricing worked out?
Price depends on the size, wall construction, strength grade and quantity. Volume pricing is available on larger orders. A quote confirms the exact cost for your size and quantity.
How fast can I get them?
Same-day shipping is available on most in-stock cardboard boxes. Custom box orders usually take 7 to 14 days and ship from multiple US shipping points.
Should I choose Mullen or ECT?
200# Mullen burst boxes are recommended for single-box UPS or FedEx ground shipments. ECT grades suit palletized, stretch-wrapped freight. Call us and we will help you pick the right board.
Can I get the boxes printed with my logo?
Yes. Boxes are available unprinted in kraft or white, or custom printed from a single color to full color. Print plates are quoted separately.
