Last Updated: April , 2026

This Return & Refund Policy applies to purchases, sample orders, wholesale orders, and product inquiries made through or in connection with the website of Dongguan Weisenupin Technology Co., Ltd. (“Weisenupin,” “we,” “us,” or “our”).

Weisenupin mainly serves wholesale buyers, distributors, retailers, and business customers. All returns, refunds, replacements, or after-sales requests are subject to review and confirmation by our sales or support team.

1. Return Request Period

Customers should inspect the goods promptly after receiving them.

If there is any product quality issue, wrong item, missing item, or shipping damage, please contact us within 7 days after delivery.

To help us review your request, please provide clear evidence, including photos, videos, order information, product labels, packaging photos, and a description of the issue.

Requests submitted after 7 days may still be reviewed depending on the product type, warranty terms, and actual situation, but they may not qualify for return or refund unless there is a confirmed product quality issue.

2. Eligible Return or Refund Reasons

Return, refund, replacement, or after-sales support may be accepted under the following conditions:

• The product has a confirmed quality defect.
• The wrong product was shipped.
• The product was damaged during delivery.
• The order was incomplete due to our fulfillment error.
• The product received is significantly different from the confirmed order details.

All requests must be supported by clear and reasonable evidence.

3. Non-Returnable Situations

Returns or refunds are generally not accepted in the following situations:

• The customer selected the wrong model, color, specification, plug type, connector, or quantity.
• The customer no longer wants the product due to personal reasons.
• The customer is subjectively dissatisfied without a confirmed quality issue.
• The product has been used, damaged, altered, repaired, disassembled, or improperly handled by the customer.
• The product is missing original packaging, accessories, manuals, labels, or other included items.
• The product cannot be resold or inspected properly due to damage caused after delivery.
• The issue is caused by misuse, improper storage, incorrect operation, unauthorized repair, or external damage.
• Customized products, OEM / ODM products, logo-printed products, special packaging products, or special-order products without quality issues.

Customized products are not eligible for return or refund unless there is a confirmed quality defect or production error.

4. Return Conditions

To be eligible for review, returned products should meet the following conditions:

• The product must be returned in its original packaging where possible.
• All accessories, manuals, labels, parts, and packaging materials should be included.
• The product must not be damaged by misuse, improper handling, or unauthorized modification.
• The customer must contact us and receive return confirmation before sending any product back.
• Unauthorized returns may be refused.

Please do not return products without first contacting our sales or support team.

5. Return Shipping Costs

If the return is caused by a confirmed product quality issue, wrong shipment, missing item, or our fulfillment error, Weisenupin will provide a reasonable solution, which may include replacement, repair, refund, or support for reasonable return shipping costs.

If a return is approved for reasons caused by the customer, including incorrect selection, incorrect shipping information, or other personal reasons, the customer will be responsible for return shipping costs and any related fees.

Import duties, taxes, customs clearance fees, and other destination charges are generally non-refundable unless otherwise agreed in writing.

6. Refund Process

After we receive the returned product, we will inspect it and confirm whether it meets the return or refund conditions.

If the refund is approved, we will process the refund according to the agreed payment method or the original payment path where possible.

Refund processing time may vary depending on the payment provider, bank, or financial institution.

We reserve the right to reject a refund if the returned product does not meet the approved return conditions.

7. Replacement or Repair

Depending on the situation, Weisenupin may offer one of the following solutions:

• Product replacement
• Partial replacement of missing or defective parts
• Repair support
• Partial refund
• Full refund
• Discount or credit for a future order

The final solution will depend on the product issue, order type, quantity, shipping situation, and communication records.

8. Business and Wholesale Orders

For wholesale orders, bulk orders, sample orders, customized orders, or OEM / ODM orders, the final after-sales terms may be confirmed separately in the quotation, proforma invoice, sales agreement, or written communication.

If there is any conflict between this policy and a written agreement confirmed by both parties, the written agreement shall prevail.
