Guaranteed Delivery. When On-Time Isn’t Optional.
Standard transit is reliable, but some shipments need more than that. Diamond Line’s Guaranteed Service gives you a defined delivery commitment for freight that can’t afford to be late.
A Higher Level of Commitment
When timing matters, Guaranteed Service gives your shipment priority handling and a defined commitment from pickup through final delivery. Whether you’re working around customer requirements, job site schedules, production deadlines, or retail receiving windows, we make it clear what to expect on the front end, so there are no surprises later.
Guaranteed Service is available on select lanes where we can confidently support the commitment within our network. When requested and confirmed, your shipment receives elevated attention throughout.
Depending on the lane, Guaranteed Service may include:
- Delivery by a specific time
- Added shipment visibility throughout transit
- Priority handling at key touchpoints in the network
- A financial service guarantee if the commitment is missed
When Is Guaranteed Service the Right Call?
Some shipments simply have less room for error. Guaranteed Delivery is a good fit when:
- A consignee requires morning or time-specific delivery
- Your shipment supports a scheduled install or service event
- Receiving windows are strict or limited
- A missed delivery would create downstream cost or disruption
Simple to Request. Transparent from the Start.
First, confirm that Guaranteed Service is available for your lane. Once confirmed, we’ll apply the service level, communicate the charge and delivery commitment, and make sure your shipment is clearly identified at pickup.
To help us meet the commitment, shipments should:
- Include complete and accurate bill of lading information
- Be identified as Guaranteed Service at the time of pickup request
- Be tendered within the required cutoff window
- Meet any lane-specific requirements communicated at booking
We’ll clearly confirm the guaranteed service level, applicable charge, delivery commitment, and any conditions or cutoff requirements. No fine print.

The Diamond Line Difference.
We’re a service-first carrier with real people on the other end of the line. Here’s what that means for your freight.
-
Direct Access to Local Support
When something goes wrong, you reach a real person who can actually solve the problem — not a ticket system or national call center. Our local teams own the relationship from first call to final delivery.
-
Flexible Routes, Not Rigid Systems
We build routes around your needs. When plans change, we adapt — with the flexibility a regional carrier can offer that larger, national networks simply cannot match.
-
Customer-First Service Model
As a 100% employee-owned company, every driver and team member has a real stake in your satisfaction. This accountability shows up in every shipment we handle — not just the easy ones.
-
Transparent Communication
Fewer surprises, clearer updates, and faster problem resolution. We proactively communicate changes so you're never left guessing about the status of your freight.
What Our Customers Say:
“My driver Loren was exceptional. He was prompt, even early, and let me know right away that his truck could not make the sharp turn in our driveway. It was pouring down rain and yet he brought both items (heavy, large, and needing a dolly) into my garage… a good 100ft walk for him. He was friendly, courteous, kind, thoughtful, and wished me a lovely day. Highest stars for a job well-done, and exceeded his requirements. Bravo!”
“John Belveal gave excellent customer service and from my take is good with people, clear with his objectives and efficient. I would recommend Diamond Line to anyone in need of a thorough and timely Freight shipping service!”
“Anthony Gallegos was an excellent driver! He was polite and curious and provided top tier customer service. He was able to deliver to a very specific location on our farm without issue and was even 2 hours early!”
