Master cases and boxes

We accept these standard case types: 

• Regular slotted carton (RSC) 

• B flute 

• ECT-32 (edge crush test) 

• 200 lb./sq. inch (burst strength) 

 Each case can weigh up to 150 lb., unless it contains a single unit that exceeds 50 lb. A case containing a single oversize unit greater than 50 lb. requires "Team Lift" labels on the top and sides. If it contains a single oversize unit greater than 100 lb., use "Mech. Lift" labels on the top and sides. 

• Do not use shippers, point-of-sale containers or pallet-sized boxes (also known as "gaylords").  

• Do not bundle boxes using bagging, taping, elastic or extra straps.  

• Do not send items in branded or competitor boxes.  

• If you’re reusing boxes from previous shipments, remove any previous labels or markings to avoid confusing the carrier. 

Each case must also have a receiving label, which we scan during receiving at the fulfillment center. Learn how to download receiving labels at WFS shipping plans: Print labels. 

Any master case not meeting these requirements may be refused and returned to you. Fees may apply. 

Packing material

Some items should be shipped with packing materials to prevent damage. Follow these guidelines to choose the right materials. For more detail, go to Prepare and pack shipments.
