If you are a lithium battery manufacturer or supply products containing batteries to Walmart, Costco, The Home Depot, or sell on Amazon US, WERCSmart registration is a mandatory hidden gateway you must pass. It is not a test report like UL, but it directly controls your listing & shelf qualification.

This article fully explains WERCSmart registration: which North American retailers require it, why it is mandatory, how to complete registration, and how much it costs.

01 What Is WERCSmart? It’s a Retail Data Pass (Not a Certification)

Many people mistake WERCSmart for a certification like UL or CE. It is not.

WERCSmart is a product safety data management platform operated by UL LLC (USA). It does not issue certificates; it is an online compliance database.

Core Logic:Suppliers upload product chemical composition, Safety Data Sheet (SDS), shipping classification, and hazard details. The system automatically assesses risks during storage, transport, sales, and disposal.Once approved, a unique WERCS ID is generated and shared with retailers, proving your product is compliant & safe.

02 Which Major North American Retailers Mandate WERCSmart?

More than 125 major retailers use WERCSmart globally, covering most of the North American retail market.All these giants require WERCSmart registration as a prerequisite for onboarding:

03 Why Must Lithium Batteries Register WERCSmart?

Lithium batteries are dangerous goods with risks of thermal runaway and fire.Retailers rely on WERCSmart for scientific compliance validation.

1. Mandatory Retailer Requirement

Walmart rules: All products containing chemicals, aerosols, pesticides, or batteries must pass WERCS assessment before listing.Unregistered shipments will be rejected or removed.

2. Supply Chain Safety

WERCS tells staff:

• How to store batteries
• Safe handling procedures
• Emergency response for leakage or fire

3. Legal Liability Protection

Inaccurate data leading to incidents will make the supplier fully liable for fines and lawsuits.

04 Three Critical Rules for Lithium Battery WERCSmart

Battery registration has strict rules; mistakes cause rejection.

Rule 1: Correct Order – “Cell First, Finished Product Later”

For finished devices (power banks, earbuds, etc.):

1. First register internal cells / battery packs
2. Then register the final productReverse order = direct rejection.

Rule 2: UN38.3 Report Is Compulsory

Since June 2019, Walmart and major retailers require:

• Valid UN38.3 test report matching the battery
• Must include TSD (Test Summary Document) (required since 2020)

Rule 3: Retail vs. Non-Retail Mode
