Warranty Policy

At Shangdon, we prioritize customer experience, and our warranty program is one of the means through which we provide high-quality after-sales service. If you have any warranty needs, please carefully read our warranty policy.

Warranty Period
Shangdon offers a 1-year limited warranty and official customer support for all new products purchased from our official store. For purchases made through authorized resellers or distributors, please contact them directly for after-sales service.

Warranty Period Calculation
The warranty period is calculated as follows:

Commencement Date
The warranty begins on the date of purchase as indicated on the digital or physical receipt.

Lost Invoice or Warranty Certificate
If the invoice or relevant warranty certificate is lost, the warranty starts three months after the production date. The production date is printed or engraved at the bottom of the product.

Replacement or Repair
If a product undergoes replacement or repair with valid documentation, the warranty period is either three months from the date of repair/replacement or the remaining warranty period of the original product, whichever is longer. Each replaced item is eligible for one replacement only.

The warranty will be void under the following circumstances:
  • Products marked as "sample" or "Not for Sale", or sold "AS IS" or sent as "prototype".
  • Products purchased from unauthorized distributors or resellers.
  • Removal, alteration, or tampering with trademarks, serial tags, or product stickers.
  • Dismantling, mishandling, improper use, or defacement of products.
