Packaging products containing liquids

On this page, you will learn how to properly prep products that are or contain a liquid so that they are protected from breaking or leaking throughout the fulfillment process.

Important: Failure to comply with FBA product preparation requirements, safety requirements, and product restrictions may result in the refusal of inventory at the Amazon fulfillment center, disposal or return of inventory, blocking of future shipments to the fulfillment center, or charging for any unplanned services.

Liquids and products containing liquids can cause damage during shipping and when stored. Products containing liquids without a double seal, including viscous products (such as honey), must be packaged securely to protect Amazon associates, other products, and customers. Be sure to adhere to the guidelines for glass containers, packaging multi-packs of liquids, and volume restrictions by container type. Sets, kits, or bundled products containing liquids must meet these requirements as well.

Watch this brief video for examples of how to prep your products for shipment to and storage in Amazon fulfillment centers.

How to Prep Liquid Products

Permitted packaging materials

  • Boxes
  • Poly bags or shrink wrap (for all liquids over 4 oz. that do no have a double seal or safety seal)
  • Bubble wrap and other approved packing material for shipping to Amazon fulfillment centers
  • Labels

Packaging guidelines

Do... Do Not...
Make sure your packaged Units can pass a 3-foot drop test onto a hard surface without breaking or leaking. A drop test consists of five drops:
  • Flat on base
  • Flat on top
  • Flat on longest side
  • Flat on shortest side
  • On a corner

Ensure the product's cap has been tightened, if applicable, and each Unit does not leak.

Make sure your products have a double-seal or safety seal (see definition below for more information).

If the liquid is double sealed and passes a drop test, no bagging is required. If the item is not double sealed regardless of size, bagging is required.

Note: Spray bottles with plastic caps that do not have an additional manufactured seal are not considered double-sealed. See examples below for a sample image.
Ship products that are classified as Hazmat or have a Flash Point less than 200 degrees Fahrenheit (93.33 degrees Celsius). See examples of hazardous and dangerous items.

Send in any Unit in violation of the volume and container restrictions described in this help page.

Ship any Unit that is leaking.

Send in any Unit without a manufactured double seal that has not been packaged with the appropriate prep materials as described in this help page.

Bundled Units: Liquids in non-glass and glass containers that are bundled to be sold as a set must adhere to the “sold as set” requirements in Packaging and prep requirements. Also, the entire bundle must collectively adhere to the 5-gallon volume requirement. Sixteen units of 34-oz. ASINs bundled together as one sellable unit is acceptable. But five units of 5-gallon ASINs bundled together as one sellable unit is not permitted.

Note: Expiration-dated products. Products that expire and are contained in packaging that requires additional prep, such as glass jars or bottles, must be prepped to ensure that the expiration date is accessible for Amazon associates during the receive process. For more information about these requirements, visit the FBA Help section on Date- and Temperature-Sensitive Products.

Definition of a double seal

A double seal is defined as a tightened lid that cannot be easily opened and one of the following:

  • A "safety seal" which is a peel-off seal underneath the lid of a product, like you would find on a new ketchup bottle.
  • A manufactured seal around the outside of the neck of the product.

Products that do not have a manufactured double seal in one of the ways above must be individually bagged in transparent sealed bags or shrink wrap (minimum of 1.5 mil.) and clearly marked with a suffocation warning label.

Examples of manufactured seals:
