Shipping Policy

We are dedicated to delivering the auto parts you need to your door as efficiently as possible. As a professional supplier of diesel truck emission system accessories, DieselPerf continuously refines our shipping services to ensure reliable, timely delivery that meets your expectations for speed and security.

1. Shipping Address Guidelines

To minimize costs and ensure smooth delivery, follow these tips when providing your address:

  • Accuracy: Double-check your shipping address for errors before placing an order.
  • Residential vs. Business Classification: If your business operates from a residential location, it will be classified as a residential address, and delivery fees will be charged accordingly.
  • Contact Information: Provide an accurate phone number. Carriers may need to reach you to verify delivery details—failure to do so could cause delays.

2. Multiple Items Shipment

We ship orders as items become available, so you may receive multiple shipments for a single order. No additional shipping fees will be charged for these separate shipments.

3. Shipping Partners

We collaborate with leading carriers including USPS, UPS, FedEx, DHL, and Amazon Logistics. We prioritize shipping from the nearest warehouse (U.S. or Hong Kong facilities) to your location. While most orders are delivered within 5–15 business days, inventory availability varies—items shipped directly from manufacturers or requiring transfer may take longer.

4. Damaged, Missing, or Lost Shipments

For Damaged/Missing Items

If you receive damaged items, incomplete orders, or suspect issues, take these steps immediately:

  1. Clearly note the damage/missing items on the delivery receipt before signing.
  2. Retain your copy of the delivery receipt.
  3. Contact our customer service team within 2 business days (email: service@DieselPerf.com; phone: +13250131608/+85253810098).
  4. Keep all damaged packaging materials for inspection.
  5. Take photos of the damaged items and packaging to support your claim.

For Lost Shipments

In rare cases of lost shipments, we work directly with the carrier to locate your items. Carrier dock checks typically take 2–7 business days. If found, delivery will proceed; if deemed lost, we will collaborate with you to find a satisfactory resolution (e.g., replacement or refund).

5. Delivery Timeframes

  • Order Processing: Our warehouses aim to process and dispatch orders within 1–2 business days.
  • Transit Time: Most items ship from U.S. warehouses, with common carrier delivery taking 1–10 business days (ground shipping typically 7–10 business days). Items from manufacturers or international locations may have longer transit times.
  • Holiday Impact: Allow extra time for delivery during major holidays. Our warehouses observe Christmas, New Year’s Day, Memorial Day, 4th of July, Labor Day, and Thanksgiving. Carriers may have additional holiday observances.
  • Force Majeure: Unforeseen events (e.g., natural disasters, global disruptions) may extend shipping times beyond standard estimates.

For further questions, contact our support team during business hours (Monday–Friday, 9:00 AM–6:00 PM).
