Does it come with a warranty?

Axion Industries LLC does not offer any type of warranty coverage for defective products except those that are manufactured by us. However, the majority of the products available through our website are covered separately under a manufacturer's warranty.

If you recently purchased a product from Axion Industries LLC and are concerned about the fitment or performance of your item, please contact us for assistance.

Our customer service representatives can provide limited support, advice, and assistance identifying the possibility of any manufacturer defects. If we suspect your product does have serious defects, our customer service department can serve as a contact with the manufacturer to help arrange a warranty inspection and, if applicable, any necessary repairs or replacement shipments.

If you wish, you may also contact the manufacturer directly for information regarding product eligibility and specific terms and conditions of warranty coverage.

What happens if I want to cancel?

Unfulfilled, cancelled orders will require a 10%-30% cancellation fee unless you choose store credit (a 5%-15% cancellation fee will apply in this case). This fee is to:

  1. Recover the processing fees for both the order you placed and the order
    you canceled.
  2. Cancellation fees imposed by the manufacturer, should the part be coming
    straight from them. OR
  3. Restocking fees, since the part now has to be resold.

The following may NOT be canceled:

  • Orders that are already fulfilled – the Returns Policy will apply.
  • Pre-orders - the Returns Policy will apply.
  • Special Order items that were approved for sourcing by the customer.
  • Items that are on sale and labeled "final sale" during that sale period.

Please see "Order Cancellation" under FAQ for more.
