Q: Purchase Order Terms

When making an order through US Diesel Parts you are agreeing to the below terms of service and related terms for returns, warranty and customer obligations for core return and eligibility for qualifying acceptance for each in question.

Q: Free Shipping Availability

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. Also, if you return an item for a refund that included Free Shipping, then the shipping charges that we paid to deliver it to you will be deducted from your refund.

Q: California Tax / Use Tax

All sales shipping to California require a City & County Sales Use Tax. We apologize for this inconvenience. If you are unsure of your local tax rates, please see: https://www.cdtfa.ca.gov/taxes-and-fees/rates.aspx

Q: Order Shipping Time

UPS / FedEx orders that are placed by 12pm MST on Monday through Friday (except holidays) will generally ship on the same day. Orders placed after 12pm MST will ship the following business day.

Some products have build-times or extended processing times but are typically noted for how long it may take before shipment. Build-Time does not include the time for arriving after shipping - Example: if an item has a 2-3 day Build-Time, it will take 2-3 days to build and will then ship out. It then take as long a time for delivery as was selected for shipment method.

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: Shipping Options

When you finalize your online order with us, you will have the choice of using several options from UPS. However, sometimes we may have to use an equal service from the another carrier depending on where your order is shipping from and the final destination of your order. If we do use another carrier such as USPS or FedEx, then we will make every attempt to see that you still receive the item as fast or faster than the UPS service that you chose. If it is important to you that a particular shipping service is used, then please call or email prior to your order to discuss your options.

Q: Delivery Times

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
  • back-ordered item

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: Shipping outside the USA

We no longer ship internationally. The main reasons for this is our industry deals in many products that require a core return for rebuild and re-manufacture. The costs to do so internationally have gone up considerably and the reliability of receiving a usable core back have gone down in turn. The other reason is that the taxes, tariffs and other border-charges have become wildly erratic - enough so that, until brought to order, we are washing our hands of it.

Q: Shipping to Alaska, Hawaii.

Yes! We do ship to Alaska, Hawaii.. 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: Shipping 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: Shipping Through Freight Forwarders.

We do NOT ship to Freight Forwarders. 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 and refunded.

Q: Back-Ordered Products or Parts

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: Returning an item purchased online

Un-used, non-defective or non-warranty items purchased online can be returned for Refund or Store Credit within (45) days after the date of purchase.

They will give you a Return Merchandise Authorization number (or RMA) to include with your return. It will also help speed up the return process if you include a copy of your original invoice. Also, please make sure and include your contact information so that we can contact you if needed.

Warranty Returns
Defective items that are still within the manufacturers warranty period may be returned for an exchange or refund depending upon the manufacturers policy. Items that have failed due to improper installation and/or negligence in correct usage by the purchaser/owner are NOT eligible for warranty return in any situation.

Warranty Return Process
A Warranty Request Form should be filled out before sending in any part for warranty return. This form can either be filled out electronically and emailed, or you can print and write out your information. Please complete the form to the best of your ability. The more complete the information we receive, the faster we can facilitate a refund or replacement. It will also help speed up the return process if you include a copy of your original invoice. Prior to sending in your part, please call us at (800) 823-4444 and speak with one of our parts specialists. They will give you a Return Merchandise Authorization number (or RMA) to include with your warranty return.

Shipping Costs on New Returns or Warranty Returns
Shipping costs on a new return or warranty return are non-refundable. This includes the initial cost to ship the item or any costs incurred in shipping back of the product for return or warranty.

Q: Returning items purchased with a gift certificate

Items that were purchased with a gift certificate cannot be returned for cash refunds. If you purchase a product with a gift certificate and wish to return it, then you will be issued a new gift certificate in the amount of the original purchase of the item. Restocking fees will be deducted from the new gift certificate issued.

Q: Restocking Fees

Returns of non-defective items for refund are subject to a restocking fee to cover costs associated with handling and invoicing. The restock charge is calculated on the total cost of your original invoice (not including shipping costs). Restock charges do not apply to warranty returns or exchanges for items of equal or greater value.
