Customer service by Amazon for seller-fulfilled orders

What is CSBA?

Customer Service by Amazon (CSBA) is a service established to support professional China-based sellers. Instead of dealing with queries directly from customers, sellers using CSBA will have Amazon Customer Service act on their behalf for items covered by CSBA ("CSBA Merchandise”), within the scope of the customer service as prescribed by Amazon. The seller agrees to comply with the following requirements when using CSBA.

The following are the benefits of using CSBA:

  • 24/7 customer service
  • Omni-channel support for phone calls, online chats and emails
  • A faster turnaround time since most of the customer contacts can be resolved at once
  • An increased Positive Response Rate when compared with non-CSBA orders
  • A professional bilingual support: Support provided in both Japanese and Chinese for sellers and customers
  • An estimated reduction in Order Defect Rates (A-to-Z Claim, Negative feedback) and return rate for self-fulfilled orders

CSBA Charges

CSBA is currently charging a flat fee rate of 38 JPY per shipped quantity. Once the seller opts for the CSBA service, the CSBA fee applies for all self-fulfilled shipped items. Customer support is available for customers once they place their orders.

Note: The fee for customer service will be charged whether a customer contacts Amazon or not. New sellers whose accounts were registered in JP in last 12 months, and who would like to opt into CSBA for the first time benefits from 90 days free trial.

Requirements and Seller Eligibility

To use CSBA, the seller must comply with the terms of use set forth below. In the event of non-compliance, or if Amazon deems that the seller’s use of CSBA is inappropriate, Amazon may, at its discretion, suspend or disqualify such a seller from using CSBA.

In such cases, sellers are required to respond to CSBA within 24 hours (includes holidays). If CSBA does not receive a response from the seller within the stipulated time period, CSBA will handle the customer query based on CSBA policy.

Return and Refund policy

  1. CSBA follows the Amazon return policies. To ensure a consistent experience for buyers, Amazon requires CSBA sellers to set forth return policies that are at least as favorable as the Amazon return policies. If a CSBA seller has a different return/refund policy, which provides better Customer experience than Amazon return policies, the seller is required to send an email to with their return policy information. Once CSBA confirms and approves the seller’s return policy, the CSBA team will follow the terms set by the policy to proceed with return/refund requests pertaining to MFN orders.
  2. CSBA sellers are required to follow OOC return policy.
  3. If a seller provides a return address in Japan, a customer who raises the return request on a CSBA order is automatically authorized to return the item, and will receive the shipping address for sending the return item. Once the seller receives the return item, the seller is required to initiate a refund to the customer following the Amazon Standard policy of return and refund.
  4. Return and refund policy of CSBA without return address in Japan:
    1. If a seller does not set a return address, CSBA will initiate a refund without return to the customer on behalf of the seller.
    2. If a seller provides an overseas return address, and does not provide a pre-paid shipping label to the customer to return the items of CSBA MFN Order, CSBA will initiate a refund without return to the customer on behalf of the seller. If the customer has shipped the items without a pre-paid shipping label, and if the seller has not refunded the customer for the return shipping fee, CSBA will refund the return shipping fee to customers.
