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.
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.
All sales shipping to California require a City & County Sales Use Tax. This tax will be assessed by City & County of your shipping address and then charged after your purchase. 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
IMPORTANT! All orders are assessed Use-Tax AFTER an order is placed. This is due to each City or County having its own tax rate between 7.25% & 11.75% and our websites web-cart not having a variable tax rate by zip code option at this time. We apologize for it not being auto-calculated at time of purchase. You can and should estimate your final cost by using the link above to find your tax rate and adding it to your orders total, do not include shipping costs when calculating.
If using PayPal or Affirm for your order, we will need to contact you for a credit card # or to send a money request through PayPal for the unpaid Use-Tax. We will not be able to ship and item until the unpaid Tax is paid in full. If you purchased with a credit card, the Use-Tax will be automatically charged after being assessed and your item will continue processing to shipment.
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.
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.
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:
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.
We no longer ship internationally other than Canada. The main reason for this is our industry deals in 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 back a usable core have gone down in turn.
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.
