Ordinary Return Checklist
For an ordinary return, the part must meet the following conditions:
New and unused: No installation or use.
Original packaging: Return the part in its original packaging.
Complete and resalable: Include all components supplied with the part.
Suspected manufacturing defects are reviewed separately under Warranty Assistance, including when the part has already been installed. Contact support with your order number, SKU, photos, and issue description. Eligibility depends on the issue and the applicable warranty terms; approval is not guaranteed.
After a return is received, we inspect it and notify you of the review result within 3 business days. Approved refunds are initiated to the original payment method within 5 business days after approval.
After the refund is initiated, funds usually appear within 5–10 business days, depending on the bank or payment provider. Cross-border bank transfers may take longer. If you have not received the refund after 15 business days from approval, contact info@dieselizumi.com. See the Refund and Returns Policy for applicable deductions.
Fees are determined by the package weight and delivery address. For heavy engine parts, we recommend contacting our team for a customized shipping quote to ensure the best possible rate.
Import duties, VAT, taxes, customs clearance fees, and local import charges are not included unless the checkout or confirmed order details clearly state that they are included. Otherwise, these charges may be collected from the buyer by the carrier or destination authority. Additional shipping charges may apply for an incomplete address or a remote delivery area. Confirm the order-specific shipping and tax details before payment.
