At Tengkun Filter, your satisfaction is our top priority! If you’ve made a purchase from us and it doesn’t meet your expectations, please don’t hesitate to reach out to us — we’re here to help.

Do you have a question about how to return an item you’ve purchased? Below is our return policy for standard products and custom products.

Return Policy: Standard Products

All standard products are returnable for credit or replacement. Requests for returns must be made within 14 calendar days of delivery. To make a return, please contact us to request a "Merchandise Return Form." The filled-out form must accompany your return.

When a Tengkun Filter standard product needs to be returned because a Tengkun Filter error occurred, such as the wrong material was used or there’s an issue with workmanship (which, we’re proud to say, is very, very rare!), a replacement order will be immediately put into process. We will give you our UPS shipping information to return the incorrect parts via UPS Ground at our expense. Replacement parts will be shipped to you via UPS Ground, again, at Tengkun Filter’s expense. If quicker delivery is needed, just let us know.

For returns that are due to a customer’s error (such as ordering the wrong item, size or quantity), a 20 percent restocking charge will be deducted from the credit issued to your account. Credit is issued for returned merchandise after we’ve received and inspected it (which we do immediately upon receipt).

Return Policy: Custom Products

Because orders and reorders for custom products are manufactured to meet your exact specifications, we’re unable to accept their return unless a manufacturing defect occurred (such as an error in workmanship or material). If you believe such an error occurred, contact us and we’ll be pleased to help rectify the situation. Credit will be issued for defective products as reasonably determined by our team.
