  • Format the date: MM-YYYY or MM-DD-YY
  • Products will be destroyed if: 
  • They are expired
  • They will expire within 90 days*

*The same ASIN within the same case or pallets must contain the same expiration date

*The master carton must have an expiration date as well

Fluid Floor Loaded Shipment Preparation Checklist

Boxes are stacked from the bottom of fluid floor loaded containers without the use of pallets

  • You are to only send standard-sized (sortable) ASINs in fluid floor loaded shipments.
  • Do not allow individual unit sizes to exceed: 
  • 18’’ x 14’’ x 8’’ OR  45cm x 35cm x 20cm for standard-sized ASINs
  • 20lbs OR 9kgs
  • Place all individual units in boxes
  • All boxes shipped to a Sortable Fulfillment Center (standard size products) must not measure any more than 25’’ or 64cm on each side
  • Large or oversized products* can be placed in larger boxes

*If you have oversized product units (individual units over 20 lbs or 9kgs), prepare them on pallets or have them clamp truck enabled.*

*Check “FBA Product Size Tiers” information on Seller Central 

  • Do not allow for your boxes to exceed 50lbs or 23kgs of sortable products in a fluid floor loaded shipment
  • Pack the same ASIN in each box 
  •  Mark the boxes as ”Case Packed”*

*You can pack multiple ASINs in the same box, but no more than 5 different ASINs are recommended to be placed in the same box

  • Make sure your packing list meets the FBA Packing List requirements 
  • Load boxes with different ASINs inside the container by loading all the boxes related to the first ASIN, then load all the boxes related to the second ASIN, and so on until the container is loaded.
  • Print box labels (Ship From, Ship To, PO # with barcode)
  • Place the box label in an easily visible location on the box (side or top)
  • Only use large-sized dunnage (air pillows, full sheets of paper, bubble wrap, sheet foam)
  • Do not use loose fill of any sort (styrofoam, peanuts, or shredded paper)


How to Load a Clamp Truck Shipment Container

What are clam truck shipments? 

 Clamp truck shipments are special floor loaded shipments received by Sortable FC’s (standard size products) and Non-sortable FC’s (oversized products). 


  • Arrange each column to be uniform and aligned with the other tiers on the base of the column. This is to make sure that all four sides of the freight column stack can be safely squeezed by the clamp.  
  • Make sure that columns are at least 24’’ or 61 cm wide and maximum 72’’ or 183 cm long.
  • Do not exceed the column maximum clamp weight of: 
  • 3000 lbs or 1360 kgs if the load is not elevated
  • 1300 lbs or 590 kgs if the load is elevated (double-stacked load) 
  • Allow at least 3’’ or 8 cm of clearance from the above the box to the container roof
  • Use air bags to allow at least 3’’ or 8 cm between container stacks and walls. This is to prevent the load from shifting or falling. 
  • Leave at least 3’’ or 8 cm between each column of boxes*, and use airbags to maintain load stability during transport.

*DO NOT bundle boxes together with straps, zip ties, tape, or other products. 

  • Allow for at least 8’’ or 21 cm of clearance from the last row of cartons to the container doors to engage a dock traveler
  • Use load bars and straps to properly secure all shipments 
  •  It is part of the shipper’s and carrier’s responsibility to make sure that shipments are loaded into a trailer in a way that will prevent the load from shifting or breaking during transit


 How to prepare for palletized shipments

  • Place FBA shipment labels on each carton 
  • Use 40’’ x 48’’ OR 1.02 m x 1.22 m, 4-way access, wood pallets*
  • If a single, large unit does not fit on a 40’’ x 48’’ pallet without hanging over the edges, use a pallet type and size more suitable for that unit
  • Whenever quantities allow for it, stack only one ASIN per pallet- label these as“Single ASIN Pallet” 
  • Only use pallets that are compliant with GMA Grade B or higher, and are made of only wood materials*

*Ship grocery or food products on GMA 1A grade pallets

  • Stretch-wrap all pallets with clear plastic. DO NOT wrap it in opaque or black stretch-wrap. 
  • Do not exceed the pallet size
  •  Height of 72’’ or 1.82m
  • Weight of 1,500 or 680 kgs
  • To protect and maintain the stability of pallets while in transit, use corner boards
  • Only use double-stacked pallets when they are safe* to load or unload and will not cause damage for the products while in transit

*It is considered safe to double stack pallets when the height does not exceed a maximum of 100’’ or 2.54 m.

  • Make sure that the maximum gross weight of each box does not exceed 50 lbs or 23 kgs unless a single unit weighs more than that 
  • Heavy units between 50 lbs (23 kgs) and 100 lbs (45 kgs) must be clearly labeled as “Team Lift” on all cartons
  • Clearly label  heavy lifts above 100 lbs (45 kgs) as “Mech Lift”


 How to load the container for palletized shipments

  •  Allow at least 6’’ or 15 cm of clearance from the top of the pallet to the container roof. 
  • Use air bags, non-metal straps, or a safety net to allow stability during transport.
  • Allow at least 3’’ or 8 cm between container stacks and walls, while in transit. 
  • Stack all cartons evenly and do not allow boxes to overhang from the pallet
  • Allow at least 8’’ or 21 cm of clearance from the last row of cartons to container doors to engage a dock leveler. 


How to Avoid Common Mistakes

  • Attach special labels to heavy products over 50 lbs or 23 kgs
  • Attach warning labels on specialty products
  • Do not prepare fluid floor loaded shipments with cartons that weigh over 50 lbs or 23 kgs
  • Oversized units and cartons have to be palletized unless the load is clampable
  • Adequately stack pallets, allowing enough space for unloading. 
  • Stack clampable shipments with at least 3’’ or 8 cm of space from the load to the roof of the container.
  • Always secure the load with air bags, non-metal straps, or safety nets to avoid the shifting of the contents during transit, which can cause damage to the products. 


Note: Containers that do not comply with the aforementioned protocol and Amazon FBA requirements, may be rejected. In that case, you will be responsible for additional storage, re-work, and re-delivery charges.
