Selling automotive parts on Walmart Marketplace requires accurate product and vehicle compatibility information. A product can be listed on Walmart, but incomplete fitment data can make it harder for customers to find the right part for their vehicle.
Walmart provides dedicated fitment reports that help sellers identify automotive catalog gaps, including products that are missing ACES coverage or required fitment attributes.
What Is Automotive Fitment?
Automotive fitment connects an automotive product with the vehicles it is designed to fit.
For example, a vehicle part may be compatible with specific combinations of:
- Year
- Make
- Model
- Engine
- Other vehicle qualifiers
Accurate fitment information helps customers identify products that are relevant to their vehicle.
Why Does Fitment Data Matter?
When automotive product data is incomplete, customers may have difficulty determining whether a part is compatible with their vehicle.
Walmart's automotive fitment reports are designed to help sellers identify missing or incomplete compatibility data. Walmart specifically provides reports for missing ACES coverage and missing fitment attributes.
For automotive sellers, reviewing these gaps can be an important part of maintaining a complete catalog.
What Is ACES?
ACES stands for Automotive Aftermarket Catalog Exchange Standard, developed by the Auto Care Association.
ACES provides a structured way to exchange vehicle fitment information, including vehicle details and related qualifiers.
In simple terms, ACES helps organize information that connects an automotive part with the vehicles it fits.
What Are the Missing Fitment Attributes?
Walmart's fitment reports identify important information associated with automotive products.
The report includes fields such as:
- GTIN
- Item ID
- Product Name
- Brand AAIA ID
- Manufacturing Part Number
- Part Terminology ID
Walmart identifies the Brand AAIA ID, Manufacturing Part Number, and Part Terminology ID as seller-provided fields in these reports.
Keeping these values accurate is important when working with automotive fitment data.
Walmart's Two Fitment Gap Reports
Walmart provides two specific reports for identifying fitment issues.
1. Fitment Missing ACES Coverage
This report identifies items that do not have ACES coverage in Walmart's systems.
It can help sellers identify which automotive products need ACES coverage review.
2. Fitment Missing Attributes
This report identifies items with one or more missing fitment attributes, such as required ACES-related information.
Using both reports can give sellers a clearer view of where their automotive catalog needs attention.
How to Review Your Automotive Catalog
A simple review process can help you identify and address fitment gaps.
Step 1: Identify the Affected Products
Start by reviewing the Walmart fitment reports and identifying the items with missing attributes or ACES coverage.
Step 2: Review the Product Information
Check the product's:
- GTIN
- Brand AAIA ID
- Manufacturing Part Number
- Part Terminology ID
- Vehicle compatibility information
Step 3: Check the Data Carefully
Make sure the information is accurate and consistent with your automotive source data.
Step 4: Correct the Missing Information
Update the affected product information using the appropriate Walmart catalog process.
Step 5: Review the Results
After making corrections, review the relevant reports again to determine whether the issues have been resolved.
Why Data Accuracy Is Important
Automotive fitment depends heavily on structured product information.
A part number, brand identifier, or terminology ID that is missing or incorrect can affect how the product's compatibility information is represented.
For this reason, automotive sellers should avoid treating fitment as just another listing field. It should be reviewed as part of the overall catalog data.
Common Automotive Fitment Issues
| Issue | What to Review |
|---|---|
| Missing ACES coverage | Check whether the item has ACES coverage. |
| Missing attributes | Review required fitment fields. |
| Incorrect brand information | Verify the Brand AAIA ID. |
| Incorrect part number | Check the Manufacturing Part Number. |
| Missing terminology information | Verify the Part Terminology ID. |
| Incomplete vehicle data | Review applicable vehicle information. |
| Catalog data inconsistency | Compare the information with your source data. |
A Simple Fitment Management Process
Managing automotive fitment does not have to be complicated.
A practical process is:
Identify → Review → Correct → Submit → Monitor
Regular catalog reviews can help sellers identify fitment gaps before they become larger catalog management problems.
