What Walmart Actually Requires: Format, Hosting, and Language
Walmart's WFS compliance team requires a Safety Data Sheet for every chemical, aerosol, or battery-containing item, formatted as a standard PDF and written in English regardless of your target marketplace.
The critical difference from Amazon: Walmart does not accept a direct file upload into item setup. Instead, you must host the SDS PDF on a file-sharing service such as Dropbox or Google Drive, generate a publicly accessible link that works without login credentials, and paste that link into the Safety Data Sheet field. If you sell multiple hazardous variants under one listing, combine every relevant SDS into a single PDF before generating the link.
Sellers frequently fail this step not because their SDS is wrong, but because the link requires a sign-in, expires, or points to a folder instead of the exact file. WFS compliance reviewers will not request access — they simply reject and move on.
The 16 Sections WFS Reviewers Check Line by Line
Walmart requires the full 16-section GHS format — the same international standard used by OSHA and Amazon. There is no shortened or exemption format for WFS.
| Section | What WFS Reviewers Verify |
|---|---|
| 1. Identification | Product name matches your Walmart listing title and brand exactly. |
| 2. Hazards | Correct GHS pictograms and signal word (WARNING/DANGER) for the finished product. |
| 3. Composition | CAS numbers and concentration ranges for hazardous ingredients, not just a trade name. |
| 9. Physical/Chemical Properties | Flash point stated with units; 'not applicable' only for genuinely non-combustible solids. |
| 14. Transport Information | Explicit DOT/IATA/IMDG classification, or a clear statement that the item is not regulated for transport. |
| 16. Other Information | Revision date present and current — stale supplier sheets from years-old batches are a common rejection cause. |
Why WFS Rejects Documents Even When an SDS Exists
Compliance review takes up to 3 business days, and Walmart will reject documentation that is inaccessible, doesn't match the product being listed, is incomplete, or is missing required sections outright.
A common failure pattern is submitting a raw ingredient supplier's SDS instead of documentation for the finished product. Walmart can use product identification and supporting information during review, so mismatched documentation can require correction or resubmission.
Providing inaccurate information, or attempting to misrepresent an item to bypass the hazmat assessment, is treated as a policy violation that can jeopardize your standing in the WFS program entirely — not just delay one SKU.

Building a WFS-Ready SDS Without a $500 Consultant
Traditional toxicology consultants charge per finished-product SDS and typically take one to three weeks — a timeline that doesn't match how quickly WFS item setup windows close.
CertiSheet generates an audit-ready, 16-section OSHA GHS SDS from your actual formula (ingredients, CAS numbers, and concentrations), correctly separating your finished product from any raw supplier sheets. Because the output is a standard PDF, hosting it on Google Drive or Dropbox for the WFS link field takes minutes, not days.
Frequently Asked Questions
Can I upload the SDS file directly into Walmart Seller Center?
No. Walmart's item setup requires a publicly accessible URL link to a hosted PDF (Dropbox, Google Drive, or similar), not a direct file attachment. The link must work without a login prompt.
How long does Walmart WFS take to review a submitted SDS?
WFS compliance review typically takes up to 3 business days. If the document is inaccessible, incomplete, or doesn't match the listed product, it is rejected and must be resubmitted.
Can I submit my fragrance oil supplier's SDS instead of writing my own?
No. Walmart requires an SDS describing your finished, formulated product as sold — not the raw ingredient sheet from your fragrance or wax supplier. Reviewers check that the product identification matches your actual listing.
What happens if my item is classified as 'fully regulated' hazmat?
Items classified as fully regulated Dangerous Goods/Hazardous Materials for transportation under DOT rules are ineligible for Walmart Fulfillment Services entirely, regardless of SDS quality. These items must be fulfilled through a different method.
