What DIAMOND CHEMICAL & SUPPLY CO’s FMCSA record shows
Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 33719
- The USDOT number is FMCSA's permanent ID for this company. It never changes, even when the business renames, moves, or changes owners, so it's the most reliable way to identify DIAMOND CHEMICAL & SUPPLY CO.
- MC number None on file
- No MC number is on file. That's normal for private fleets hauling their own goods and for intrastate-only carriers, but a company with no MC number can't legally haul regulated interstate freight for hire.
- Operating status Inactive
- FMCSA lists this USDOT number as inactive. Inactive carriers shouldn't be dispatched; confirm the company has reactivated before booking a load.
- Operation type Interstate
- Interstate carriers can haul freight across state lines and fall under the full federal safety rules (FMCSRs).
- Fleet size 3 power units, 3 drivers
- DIAMOND CHEMICAL & SUPPLY CO self-reports 3 power units (trucks and tractors), which makes it a small fleet. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
- Last MCS-150 update Nov 10, 2023
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. DIAMOND CHEMICAL & SUPPLY CO last filed it on Nov 10, 2023. That's past FMCSA's two-year update requirement. Confirm the address, phone, and fleet size directly.
