Shipping & Returns

Q: Do you offer Free Shipping?

As you browse through our website, you'll notice that we do offer free shipping on many items. Our free shipping offer is only good for select items that are marked to include free shipping, and the order must be shipped to an address within the lower 48 states within the United States. Orders shipping outside of the United States (lower 48) do not qualify for free shipping.

Q: When will my order ship?

UPS orders that are placed by 2pm MST on Monday through Friday (except holidays) will generally ship on the same day. UPS orders placed after 2pm MST will ship the following business day.

USPS Priority Mail orders that are placed after 10am MST on Monday through Friday (except holidays) will generally ship on the following business day.

We cannot guarantee same day shipments or what carrier is used on orders that are drop-shipped from other warehouses due to item availability, different time zones and warehouse policies. If there are any known delays then we will attempt to contact the customer as soon as possible. If it is important that you receive your item by a specific date, then please call us to verify availability and discuss shipping options.

Q: What shipping options are available?

All web orders shipping to the United States are shipped by UPS or USPS using the service of your choice during checkout. We can also use FedEx by special request for orders shipping to the United States. If you would like your order shipped via another carrier such as FedEx, then you will need to contact us before ordering to get a shipping quote. International orders are shipped via UPS only, no exceptions.

Q: My order wasn't delivered on time. Why?

If the item you ordered isn't immediately available to ship, then we will make every effort we can to contact you. However, many other things can affect the delivery time of your order such as:

  • time of day the order was placed
  • weekends or holidays
  • increment weather
  • mechanical problems

Please keep in mind that expedited delivery services do not apply to weekends or holidays. For example, if you order an item on a Friday and choose UPS Next Day Air, it will arrive on the following business day (not Saturday). If you need an item to be delivered on a weekend or holiday, then please call us at (800) 823-4444 to discuss your options.

Shipping companies do not guarantee delivery times during major holidays or during increment weather. Please allow extra time for deliveries during these times. You can also contact us to verify availability and to discuss expedited shipping options if it is important that you receive your order by a specific time.

Q: Do you ship outside of the USA?

Yes, we ship all over the world with UPS! If you would like a shipping quote to your location, then simply add the item(s) to your shopping cart and follow the instructions to fill out your shipping information. You will be able to see a shipping quote without committing to purchase. If you have any questions regarding shipping, then please feel free to contact us.

Q: Do you ship to Alaska, Hawaii or Canada?

Yes! We do ship to Alaska, Hawaii & Canada. However, shipments to those areas are excluded from our Free Shipping offers. It should also be noted that our website isn't very good at calculating shipping charges outside of the lower 48 states, so the shipping rates calculated during checkout may be subject to additional shipping charges. This is rare, and if it does happen, then we will contact you.

Q: Do you ship to APO/FPO addresses?

Yes, we are happy to ship to APO/FPO address' through our website. However, if you experience any problems with an APO/FPO address during checkout, then please call us and we will help complete your order over the phone.

Q: Do you ship to Freight Forwarders?

No, we do not. There are no exceptions. If you place an order and use a freight forwarding company as a delivery address, then your order will be canceled.

Q: I was told that my parts are on backorder. Why?

Occasionally the manufacturers we order our parts from can run into production problems that may prevent us from keeping those items on our shelf at all times. If you order an item that we don't have in stock, then we'll contact you to let you know that your order has been placed on backorder. This means that we intend to fill your order as soon as your item(s) are available.

Q: How do the online Gift Certificates work?

Some products on our website include a free Gift Certificate that is good towards your next online purchase at USDieselParts.com. When you purchase an item that includes a free Gift Certificate, you will be sent a unique code that you can use during your next online purchase to redeem your Gift Certificate. This unique code is only redeemable by the purchaser of the original product.
