Return & Refund Policy

Return & Refund Policy

Last updated: August 31, 2026

SEFINN FOUR is operated by Tianjin Haimaotong Information Technology Co., Ltd. Eligible products may be returned within 30 days of delivery, subject to the conditions below. Authorized customer returns are handled within the United States.

Return Eligibility

To qualify for a standard return, the item must be unused, uninstalled, unaltered, and in resalable condition with its original packaging, components, hardware, manuals, and accessories. Products that have been installed, wired, modified, cut, or damaged after delivery are generally not eligible for a standard return unless the issue is a verified product defect or shipping damage.

Sale Items

Sale-priced products are eligible for return under the same standard return conditions unless an item is clearly identified as Final Sale before purchase.

Start a Return Before Shipping

Email support@sefinnfour.com with your order number and reason for return. Do not send a product back without return authorization. After the return is approved, we will provide the applicable U.S. return address and return instructions for the order.

Damaged, Defective, or Incorrect Items

If your order arrives damaged, defective, incomplete, or incorrect, contact us within 7 days of delivery and include your order number plus clear photos or video showing the issue and packaging where relevant. After review, we may provide replacement parts, a replacement product, a prepaid return solution, or another appropriate remedy.

Return Shipping

For returns that are not caused by a product defect, shipping damage, or our fulfillment error, the customer is responsible for return shipping costs. Original shipping charges, if any, are not refundable. For a verified defect, shipping damage, or incorrect item caused by us, we will provide the appropriate return or replacement solution at no additional return-shipping cost to the customer.

Refunds

Once an authorized return is received and inspected, we will notify you of the result. Approved refunds are issued to the original payment method. We generally process approved refunds within 3–5 business days after inspection; your bank or payment provider may require additional time to post the credit.

Exchanges

For a different model, finish, or size, the fastest method is generally to return the eligible original item and place a new order. If an item is defective or damaged, contact us first so we can determine the most appropriate resolution.

Order Changes and Cancellations

If you need to change or cancel an order, contact us as soon as possible. We cannot guarantee changes or cancellation after an order has entered processing or shipment.
