Shipping & Delivery Policy
At DieselPerf, we specialize in high-performance diesel emission system accessories. Our mission is simple: to deliver the parts you need with maximum efficiency, security, and transparency. Below are the guidelines we follow to ensure your order reaches you safely.
1. Perfecting Your Delivery
To ensure a seamless experience and avoid unnecessary surcharges, please keep the following in mind:
- Precision Matters: Always verify your shipping address at checkout. Accurate data prevents costly rerouting fees.
- Address Classification: Carriers determine rates based on zoning. If your business is located in a residential area, it will be classified and billed at the Residential Delivery rate.
- Stay Reachable: Please provide a valid phone number. Carriers often need to coordinate delivery windows; missed connections can lead to significant delays.
2. Order Consolidation
To get your parts to you as fast as possible, we ship items as they become available. This means your order may arrive in multiple packages. Rest assured, you will never be charged extra for these split shipments.
3. Our Logistics Network
We partner with world-class carriers, including UPS, FedEx, DHL, USPS, and Amazon Logistics.
- Global Fulfillment: We fulfill orders from our strategic hubs in the U.S. and Hong Kong, prioritizing the location closest to you.
- Lead Times: While most orders arrive within 5–15 business days, specialty items or factory-direct shipments may require additional transit time.
4. Damaged or Missing Shipments
Your satisfaction is our priority. If your order arrives compromised, please follow this protocol:
For Damaged/Incomplete Deliveries:
- Document Immediately: Note any visible damage or missing pieces on the delivery receipt before signing.
- Contact Us: Reach out within 2 business days at service@DieselPerf.com or via phone at +1 325-013-1608 / +852 5381 0098.
- Preserve Evidence: Keep all original packaging and take clear photos of the damage to expedite your claim.
For Lost Shipments:
If a package goes missing, we will initiate a dock check with the carrier (typically taking 2–7 business days). If the items cannot be located, we will work with you to provide a full replacement or a refund.
5. Estimated Timeframes
- Processing: Orders are generally dispatched from our warehouse within 1–2 business days.
- Transit: Standard U.S. ground shipping typically takes 7–10 business days, though many items arrive sooner.
- Holiday & External Factors: Please account for seasonal peaks (Christmas, Thanksgiving, etc.) and unforeseen "Force Majeure" events like extreme weather, which may naturally extend delivery windows.
