Refund policy

At Kunming Weisan Energy-Saving Technology Co., Ltd., we want you to be satisfied with your purchase. If there is a problem with your order, please contact us for assistance.

This voluntary return policy supplements your rights under applicable law.

1. Return Eligibility

You may request an eligible return within 30 days of delivery.

For voluntary change-of-mind returns, items must be unused, unaltered, in their original packaging, and in the same condition as received. Please include any supplied accessories and components.

An order number, receipt, or another proof of purchase is required.

Our voluntary change-of-mind return offer does not cover:

  • Items clearly marked “Final Sale.”

  • Products used, damaged, or altered by the customer.

  • Items missing their original packaging or supplied components.

These conditions and exclusions do not limit applicable statutory inspection or withdrawal rights, or remedies for damaged, defective, or incorrectly supplied goods.

2. How to Request a Return

Email service@sulvibe.com with:

  • Your order number or proof of purchase.

  • The item you wish to return.

  • The reason for your request.

  • A description of any damage, defect, or incorrect item, with photographs where available.

We will review your request and provide return instructions and the appropriate return address.

Our registered company address is not automatically the return destination.

Please contact us before sending a voluntary return so we can direct it to the correct location. Prior approval is not a condition for exercising a statutory right that does not require it.

3. Return Shipping Costs

Customers are responsible for return shipping costs for change-of-mind returns.

If an item arrived damaged, defective, or incorrect, we will cover reasonable return shipping costs or arrange another appropriate solution. Please contact us before purchasing postage so we can arrange or confirm a suitable shipping method.

We recommend using a trackable shipping service and keeping your postage receipt and tracking details.

4. Refunds and Processing Time

After receiving your return, we will inspect it and notify you of the refund decision. If a refund is declined or reduced, we will explain the reason.

Stage Estimated processing time
Issuing an approved refund Within 3 business days of approval
Bank or payment provider posting the credit An additional 3–8 business days after issuance

Refunds are normally issued to the original payment method.

These processing periods do not extend any shorter deadline required by applicable law.

5. Late or Missing Refunds

If more than 8 business days have passed since we issued your refund:

  1. Check your bank account or credit card statement again.

  2. Contact your bank or payment provider to check the refund status.

  3. If the refund is still missing, email service@sulvibe.com for further assistance.

6. Damaged, Defective, or Incorrect Items

Please contact us as soon as possible, preferably within 7 days of delivery, if your item arrives damaged, defective, or incorrect.

Include your order number, a description of the issue, and photographs where available.

This suggested reporting period does not shorten your statutory rights or exclude a defect discovered later.

After reviewing the issue, we will arrange an appropriate solution, which may include a replacement, return, or refund, depending on the circumstances and applicable law.

7. Canceled Orders

We do not charge a cancellation fee.

If a paid order is successfully canceled, we will issue a full refund to the original payment method within 3 business days of confirming the cancellation.

Your bank or payment provider may require an additional 3–8 business days to post the refund.

Please refer to our Shipping Policy and Terms of Service for order change and cancellation arrangements.
