Overview
If you encounter an error stating that additional information is required to complete the Hazmat review, it means Amazon has flagged the product for a Dangerous Goods (Hazmat) review. Amazon must verify that the product is safe to store and ship through their fulfillment centers before allowing it to be included in an FBA shipment.
This review is common for products such as cosmetics, cleaning products, liquids, sprays, batteries, or items containing chemicals or alcohol.
Why This Error Appears
When creating an FBA shipment, Amazon checks whether the product requires a Hazmat safety review. If the product has not yet been reviewed, Amazon will block it from being added to the shipment until the required information is submitted.
You may see an error message similar to:
“Additional information is mandatory in order to complete the Hazmat review.”
This means Amazon needs additional product safety information before approving the item for FBA.
How to Resolve the Hazmat Review
Step 1: Go to Amazon Seller Central
Log in to your Amazon Seller Central account.
Step 2: Navigate to Your Inventory
Go to:
Inventory → Manage All Inventory
Step 3: Locate the Product
Search for the product using the ASIN or SKU.
Step 4: Check the Dangerous Goods Review
If the item requires a Hazmat review, you will see an option to Provide Dangerous Goods Information or Complete Hazmat Review.
Click the link and complete the required information.
Step 5: Submit the Required Details
Amazon may ask for:
Confirmation if the item contains liquids, batteries, or flammable materials
Product ingredient information
A Safety Data Sheet (SDS) (for certain chemical products)
Once submitted, Amazon will review the information.
Fastest Way to Clear This Error
In many cases, the fastest way to resolve this issue is to manually confirm the product is not hazardous.
Quick Method
Go to Manage All Inventory in Seller Central
Locate the affected ASIN
Click Provide Dangerous Goods Information
Answer the questionnaire confirming the item is not hazardous
For many products such as face wipes, cosmetics, or household items, this questionnaire can be completed in just a few minutes.
After submission, Amazon will usually update the Hazmat status within a few minutes to several hours.
Important Notes
This is not an AccelerList error. The restriction comes directly from Amazon’s Dangerous Goods (Hazmat) system.
The item cannot be added to an FBA shipment until the review is completed.
Some items may require an SDS document, which can take longer to review.
After the Hazmat Review Is Approved
Once Amazon completes the review and approves the product:
Return to AccelerList or Seller Central
Recreate or continue your FBA shipment
The item should now be allowed in the shipment without errors
Summary
The Hazmat review error occurs when Amazon needs to verify the safety of a product before allowing it into FBA. Completing the Dangerous Goods questionnaire in Seller Central is usually the fastest way to resolve the issue and proceed with your shipment.
