Return & Refund Policy
This policy explains when Doutergas customers may request a return, how to request one, where approved returns should be sent, how return shipping is handled, and when approved refunds are issued.
01 · RETURN OVERVIEW
180-Day Free Return

04 · RETURN AUTHORIZATION
Please Wait for Return Instructions
Please obtain the applicable return authorization and instructions before shipping an item back. Following the authorized return process helps ensure that the returned package can be correctly identified, inspected, and linked to your order.
05 · RETURN ADDRESS
Registered Business & Return Address
The registered business address of Inner Mongolia Wangyi Technology Co., Ltd. is also the designated return address for approved Doutergas returns.
Approved returns should be sent to this address only after the applicable return instructions have been provided.
06 · RETURN SHIPPING
180 Days Free Return
Eligible approved returns within the 180-day return period qualify for the applicable free-return arrangement provided or authorized by Doutergas.
Customers should follow the authorized return method provided for the approved request rather than arranging an alternative return method without instructions. This helps avoid unnecessary shipping costs or processing problems.
07 · DAMAGED, DEFECTIVE OR INCORRECT ITEMS
When There Is a Problem With Your Order
If a product arrives damaged, defective, incorrect, incomplete, or materially different from the product ordered, please contact us at service@doutergas.com and provide the relevant order information and clear photos or videos where appropriate.
After review, Doutergas will provide an appropriate replacement, refund, return, or other reasonable solution. Customers will not be required to bear approved return-shipping costs arising from a damaged, defective, incorrect, incomplete, or otherwise merchant-side order issue.
08 · PREFERENCE-BASED RETURNS
Changed Your Mind?
A preference-based return may be requested within the applicable 180-day return period if the product meets the return eligibility requirements. Eligible approved returns qualify for the free-return arrangement applicable to the order when the authorized return process is followed.
09 · RETURN INSPECTION
What Happens After We Receive Your Return
Once an approved return is received, it may be inspected to confirm the returned product, its condition, and the applicable return request. If additional information is reasonably required to complete the review, Doutergas may contact the customer using the contact information associated with the order.
10 · REFUNDS
Refund Processing
Once the returned item has been received, inspected, and the refund has been approved, the applicable refund will be issued to the original payment method within 5–10 business days.
After Doutergas issues the refund, additional time may be required for the relevant payment provider or financial institution to post the funds to your account. Processing times outside our control may vary by payment provider.
11 · REFUND METHOD
Returned to the Original Payment Method
Approved refunds are returned through the applicable original payment method used for the purchase. Available payment methods are those displayed at checkout when the order is placed.
12 · ORDER CHANGES & CANCELLATIONS
Contact Us as Soon as Possible
If you need to request an order cancellation or change, please email service@doutergas.com as soon as possible. We will make reasonable efforts to assist, but cancellation or modification cannot be guaranteed once order processing, fulfillment, or shipment has begun.
13 · REFUND STATUS
Haven't Received an Approved Refund?
If the applicable refund processing period has passed and the refund is still not reflected in your account, please first review the original payment account and contact the relevant payment provider or financial institution where appropriate. You may also contact us at service@doutergas.com for assistance with the refund status.
