FMCSA Southern Service Center
South Carolina is home to 8,600+ registered motor carriers running freight through major corridors like I-85 and I-26. Freight hubs in the state - Port of Charleston and Inland Port Greer, plus Columbia Distribution - drive a compliance burden that touches every carrier operating in or through South Carolina: federal filings through FMCSA and IRS, plus South Carolina-specific surcharges. South Carolina is anchored by the Port of Charleston (one of the fastest-growing East Coast container ports) and the Inland Port at Greer that connects via rail to the port - extending the port's effective reach across the Southeast. South Carolina State Transport Police run weigh stations on I-85, I-95, and I-26. The I-85 corridor through Greenville-Spartanburg is one of the busiest commercial truck routes in the Southeast.

Filings South Carolina carriers need
BOC-3 Filing
$75 flat (lifetime)
A BOC-3 designates a process agent in every US state so the FMCSA has a local point for service of legal process on your operating authority.
USDOT & MC Authority
From $299 (plus FMCSA $300 filing fee)
A USDOT number is the FMCSA safety identifier every commercial motor vehicle operator needs; MC operating authority is the for-hire interstate license that lets you legally haul freight for compensation.
UCR Registration
From $55 (Bracket A, 0–2 power units, 2027 schedule; $46 for 2026)
UCR is the annual federal fee that every interstate motor carrier, broker, and freight forwarder pays through their base state to fund safety and economic enforcement programs.
MCS-150 Update
$100 service fee ($200 once for lifetime updates)
The MCS-150 is FMCSA's biennial check-in form for every USDOT holder - fleet size, driver count, operational mileage, and safety contact information.
Form 2290 (HVUT)
From $149
Form 2290 is the federal Heavy Vehicle Use Tax (HVUT) return for trucks 55,000 lbs taxable gross weight or higher. Filing produces the stamped Schedule 1 - proof of payment that state DMVs require for truck registration renewal.
State Trucking Permits
Varies by program (NY HUT $19+, KY KYU quarterly, NM WDT, OR weight-mile, CT HUF)
State trucking permits cover any state-specific authorization, weight-distance tax, or commercial surcharge that stacks on top of federal UCR, MCS-150, and Form 2290 - required when operating commercial vehicles on a particular state's highways.
Driver Screening
From $39 (MVR-only); full pre-hire pack from $89
Driver screening combines the Motor Vehicle Record (MVR), CDLIS query, Pre-Employment Screening Program (PSP) report, and FMCSA Clearinghouse query - the four federally-required pre-hire checks for any commercial driver position.
Authority Reinstatement
$275 flat
Authority reinstatement reactivates a previously-revoked or inactive MC operating authority - required when FMCSA has revoked authority due to lapsed insurance, missed MCS-150, unpaid civil penalty, or out-of-service safety violations.
South Carolina state-level surcharge
On top of federal UCR, MCS-150, and Form 2290.
No state weight-distance tax beyond IFTA
