Shipping, Returns & Refund Policy

Shipping Policy

U.S. Shipping

We may occasionally use a shipping carrier different from the one selected at checkout to improve delivery speed, protect fragile items, or reduce overall shipping and handling costs, including packaging and processing.

International Shipping

International shipping charges are calculated at checkout and do not include customs duties, taxes, brokerage fees, or tariffs imposed by your country upon import. These fees are not controlled by Insane Diesel and vary by location and local regulations.

Customers are solely responsible for all import-related charges. We strongly recommend contacting your local customs office or postal service in advance to understand applicable fees before placing an order.

Canada: Estimated duties and taxes may be reviewed at https://www.cbsa-asfc.gc.ca/travel-voyage/dte-acl/est-cal-eng.html

Return & Refund Policy

General Return Policy

Due to the nature of aftermarket automotive components, returns are not accepted for buyer’s remorse, incorrect ordering, or compatibility issues. Customers are responsible for verifying vehicle compatibility prior to purchase. We encourage reviewing installation guides and confirming pressure and return port locations before ordering.

Products that have been installed, used, modified, contaminated with oil or fluids, or show signs of installation are not eligible for return or refund, except where required by law.

Any return request must be approved in advance. Returns sent without authorization may be refused.

Damaged, Defective or Missing Items

All products are inspected prior to shipment. If your order arrives damaged or defective,  you must notify us within 7 business days of delivery and provide clear photos of the damage and packaging. 

Only unused items in original condition are eligible for replacement or refund. Upon inspection and confirmation, you may choose between a replacement or a full refund.

Missing components must be reported within 15 days of the delivery date. Each order is packed individually to help ensure all components are included and to maintain quality control. A packing slip/manifest is included with every shipment; please review it upon delivery to verify that all components were received.

Approved Returns & Refunds

In rare cases where a return is approved (outside of damage on arrival), requests must be made within 30 days of delivery.

Approved refunds will be issued minus:

• Return shipping costs
• Original outbound shipping costs (even if free shipping was offered)
• Payment processing fees charged by Shopify (approximately 2.4–2.5% + $0.30)

Refunds are issued to the original payment method after returned items are received and inspected.
