Refund policy
Last Updated: May 20, 2026
Order Cancellation Policy
Due to the nature of diesel performance products and tuning services, orders placed through DEFDelete.com begin processing shortly after checkout. Shipping labels, warehouse allocation, manufacturer requests, and tuning preparation may begin immediately after payment is received.
Because of this rapid processing workflow, submitted orders may not always be eligible for cancellation.
If a cancellation request is approved before shipment or production begins, cancellation and processing fees may still apply and will be deducted from the refund amount.
Once an order has shipped, customers must wait until delivery is completed before requesting a return under the conditions outlined below.
Non-Returnable & Final Sale Products
Certain products sold by DEFDelete are considered final sale and are not eligible for return, refund, or exchange once processing, programming, calibration, or production has started.
Final sale items may include:
- Custom tuning files and calibrations
- Bench flash services
- Pre-programmed tuning devices
- Unlock services
- Special-order exhaust systems
- Race pipes and delete components
- Products built or configured specifically for the customer
Customers are responsible for confirming vehicle compatibility and product selection before placing an order.
Return Eligibility
Eligible return requests must be submitted within 30 days of delivery unless otherwise stated.
Returned products must:
- Be unused and uninstalled
- Be returned in original packaging
- Include all hardware, accessories, manuals, and components
- Be free from damage, modification, or missing parts
DEFDelete reserves the right to deny returns that do not meet these requirements.
RMA (Return Authorization) Procedure
Before returning any product, customers must contact our support team to obtain a Return Merchandise Authorization (RMA).
Return requests should include:
- Order number
- Description of the issue
- Photos or supporting documentation if applicable
Products returned without an approved RMA may be refused or returned to the sender.
Defective or Damaged Products
If a product arrives damaged or you believe a manufacturing defect exists, please contact DEFDelete as soon as possible after delivery.
Once the issue is reviewed and verified, we may provide repair, replacement, store credit, or refund options depending on the situation and manufacturer policies.
Refused Shipments & Unclaimed Deliveries
Customers are responsible for accepting delivery and paying any applicable customs duties, import taxes, brokerage fees, or related charges required by the destination country.
If a shipment is refused, abandoned, returned, or unclaimed for any reason, the customer remains responsible for all resulting costs, including:
- Original outbound shipping charges
- Return shipping fees
- Carrier handling or rerouting charges
- Import duties and customs fees
- Storage fees or carrier penalties
- Cancellation or restocking fees
These charges are non-refundable and may be deducted from any approved refund amount.
If total charges exceed the original order value, the customer may remain responsible for the remaining balance.
Shipment Verification & Carrier Tracking Limitations
Tracking information is only available while retained within the carrier’s tracking system. Once the carrier’s retention period expires, shipment records and delivery confirmation may no longer be accessible.
Customers are responsible for monitoring shipment status and reporting any non-delivery, missing package, or shipping issue within a reasonable period after the estimated delivery date.
If a claim regarding non-receipt or delivery issues is submitted after tracking information is no longer available from the carrier, we may be unable to verify the shipment status, initiate a carrier investigation, or provide a replacement, refund, or resolution, as the shipment can no longer be independently validated through the carrier system.
These limitations are determined by the shipping carriers and are outside of our control.
International Orders
Customers placing international orders are responsible for understanding local import regulations, emissions laws, customs procedures, and product restrictions before purchasing.
DEFDelete is not responsible for delays, customs holds, seized shipments, import restrictions, or additional charges imposed by local authorities or carriers.
Refund Processing
Approved refunds are processed after returned items are received and inspected by our team.
Refund timelines may vary depending on payment providers, financial institutions, and carrier claim investigations.
Original shipping charges, expedited shipping upgrades, import fees, and certain processing costs may not be refundable.
Chargebacks & Payment Disputes
Customers agree to contact DEFDelete directly before initiating chargebacks or payment disputes whenever possible so that we have an opportunity to resolve the issue.
Fraudulent or abusive chargebacks may be disputed with supporting documentation, shipment tracking, communication history, and order verification records.
Policy Updates
DEFDelete reserves the right to modify or update this Refund & Return Policy at any time without prior notice.
Updated versions will be posted on this page with a revised effective date.
