Last updated on May 21, 2026
Reading time: 3 min
Overview

Hazardous materials are any item that is or contains chemicals, aerosols, pesticides or batteries. When you choose Walmart Fulfillment Services Canada (WFS), we require additional information to safely store and handle your items. After you submit an item, the compliance team will review the information before approving the item. In this guide, we’ll show you how to fill out hazmat fields and what to expect from the compliance review. 

Notes:

Providing inaccurate information may result in item setup delays and regulatory liability. Falsely representing your items in an effort to bypass these assessments is prohibited and could result in expulsion from the WFS program. Examples of false representation include but are not limited to: providing incorrect responses; misrepresenting the item in the name, description or images; intentionally misspelling words; omitting key information and later adding it after the item has been reviewed. 

Required item setup fields for hazmat

 No matter which item setup method you’re using, you’ll fill out these fields for Walmart-fulfilled items. You can find most of this information in the Safety Data Sheet, manufacturer’s website or item packaging.

Link to a JPG, PNG or BMP of the label so it can be shown in your Walmart.ca listing. Make sure it’s publicly accessible and is under 1 MB. For more detail, visit Image guidelines and requirements. Here’s an example of a correct label image showing an ingredient list:

Safety Data Sheet  

Required if your item is or contains:  

  • Chemical 
  • Aerosol 
  • Pesticide

And/or battery types:  

  • Lead acid 
  • Lead acid (non-spillable) 
  • Lithium metal

A Safety Data Sheet (SDS) is a document prepared by the manufacturer that lists hazards and safety precautions for a substance. The SDS must be in English. It should have 16 sections of standardized information, including physical and chemical properties (section 9) and transport information 
 
You’ll need to provide a publicly accessible link to the SDS. If the link is invalid, you won't be able to set up items. If you don’t have the SDS for your items, reach out to the manufacturer or search online. 

 

If your item has multiple hazardous components, please combine each SDS into one document. To learn more about SDS, go to WFS Compliance: Safety Data Sheets.

Number of Unique Hazardous Components  

Required if your item is or contains:  

  • Chemical 
  • Aerosol 
  • Pesticide 
  • Battery

Enter the number of components within the item that may be hazardous.  
   

Example: A remote-control car contains batteries in both the car and the remote, so there are 2 hazardous components within the item. Other examples include makeup kits, vehicle detailing kits and art sets. 

Batteries Included  

Required if your item is or contains: 

  • Battery

Tell us if batteries come with the item or not. If your item doesn’t come with any batteries, select "No."

Required if your item is or contains:  

  • Battery

This lets customers know which size of battery to buy for the device. Find battery size on the manufacturer's website, item packaging or Safety Data Sheet. 

 

If you can't find your battery size or don't see it listed, select "Proprietary Device Specific." For more battery guidelines, visit WFS compliance: Batteries.

Example: AA, AAA, CR2330, 12-Volt 

Lithium Ion Batteries  

This section is required if the battery type is lithium ion. Lithium-ion  batteries are generally rechargeable and found in electronic devices, such as laptops and tablets. 

Battery Model  

Required if battery type selected is:  

  • Lithium ion 

Enter the model name and number for the battery. You can find this on the manufacturer’s website, item packaging or the battery itself. For instance, laptop battery models are listed on the battery compartment or on the battery. 

Example: Canon LP-E17 

Battery Form Factor  

Required if battery type selected is:  

  • Lithium ion 

This describes the shape of the battery.  You can find this information on the item packaging or manufacturer’s website. 

  • Battery: a unit with multiple cells linked together in a protective case with a positive and negative terminal (e.g., 18V battery pack for a power tool)
  • Cell: a single, cylindrical unit (e.g., AA battery)
  • Button cell: a small unit that’s shaped like a button or coin  (e.g., CR2032 used in a car key) 

Battery Count  

Required if battery type selected is:
