SC Inland Port Insurance: What Carriers Hauling to Greer and Dillon Miss

Most carriers running drayage to Inland Port Greer or Inland Port Dillon think they're covered because they have a trucking policy in force. They find out they're not when a chassis gets damaged, a cargo claim comes back denied, or a shipper's certificate of insurance requirements don't match what their policy actually says. SC inland port trucking insurance is not the same product as a standard OTR policy, and the difference matters before you pull the first load, not after.

What the SC Inland Ports Actually Are and Who Hauls There

The SC Ports Authority operates two inland ports that function as rail-connected extensions of the Port of Charleston. Inland Port Greer sits in the Upstate near Spartanburg and Greenville, serving the BMW manufacturing plant, automotive suppliers, and the dense industrial base along the I-85 corridor. Inland Port Dillon sits in the Pee Dee region near the I-95 and I-74 interchange, serving distribution centers and agricultural shippers who want an alternative to routing everything through the Charleston terminal.

Both facilities move containers via Norfolk Southern rail, which means the freight arriving and departing is intermodal freight, not standard truckload freight. The carrier profile at these ports skews toward regional and local drayage operators: owner-operators running one or two trucks, small fleets with five to fifteen power units, and sometimes OTR fleets that pick up drayage work to fill capacity on South Carolina turns. These are not the same carriers doing flatbed hauls on I-26 or dry van moves between distribution centers. They operate under different contractual conditions, pull equipment they don't own, and face liability questions that standard trucking policies were never designed to answer.

If your operation touches these lanes, understanding trucking & transportation in South Carolina means understanding the intermodal layer specifically, not just the general motor carrier framework.

Why Intermodal Drayage Creates Coverage Gaps Standard Policies Don't Address

In a standard OTR move, the motor carrier operates under its own FMCSA authority, hauls freight under its own bill of lading, and the liability structure is relatively straightforward. Intermodal drayage at an inland port works differently. The carrier is often operating as a dray agent for a beneficial cargo owner, a non-vessel operating common carrier, or directly under the steamship line's authority. The container belongs to a shipping line. The chassis belongs to someone else entirely. The bill of lading may be the ocean bill, not a domestic one.

That arrangement creates a liability gray zone. Your primary trucking liability policy is written to cover you operating under your own authority, hauling freight under your own responsibility. When you're pulling under someone else's authority or operating as a subhauler for an intermodal intermediary, some policy forms will not respond the way you expect. The ISO form MCS-90 endorsement satisfies federal financial responsibility requirements under FMCSA minimum financial responsibility rules, but the MCS-90 is a backstop, not a coverage grant. It does not fix the underlying gaps in your policy form.

South Carolina drayage insurance needs to be placed on a form that explicitly addresses drayage operations, intermodal work, and the contractual arrangements common to port-adjacent freight. Many standard trucking markets write those operations out of the policy or exclude them by endorsement without the carrier ever noticing.

The Chassis Problem: Who Owns It and Who Is Liable When Something Goes Wrong

This is where most inland port carriers get hurt. At Greer and Dillon, carriers routinely pull chassis from the SCPA chassis pool or from chassis owned by shipping lines and leasing companies. The carrier does not own the chassis. The carrier did not buy physical damage coverage on the chassis. But the carrier is operating the chassis on public roads, and when something goes wrong, the question of who is liable is not simple.

If the chassis is damaged during the move, whether from an accident, a tire blowout that causes road damage, or a mechanical failure that results in a loss, the chassis owner will look to the carrier for recovery. If the carrier's physical damage policy does not specifically extend to non-owned trailers and chassis, the carrier is exposed for the full cost of the equipment. A chassis is not cheap to repair or replace, and chassis owners pursue carriers aggressively because they know most carriers assume they're covered when they're not.

The liability exposure is a separate issue. If a chassis defect contributes to an accident, liability can be shared between the carrier and the chassis owner. That sounds like good news until you realize that the carrier's insurer may deny the claim or seek contribution from the carrier on the basis that the carrier accepted a defective chassis and put it on the road. Pre-trip inspection documentation and the chassis interchange agreement become critical evidence. Neither one helps you if your policy has no language addressing chassis interchange liability.

Every intermodal trucking insurance policy placed for SC inland port work needs explicit chassis interchange coverage with a limit that reflects the actual value of equipment being operated. That means checking the endorsement, not just the declarations page.

Cargo Coverage Conflicts Between Carrier and Shipper Contracts at the Inland Ports

Shippers and BCOs who use SCPA's inland ports frequently impose cargo insurance requirements in their drayage contracts. Those requirements are often written by logistics attorneys or supply chain managers who base the numbers on the value of the freight, not on what a standard motor truck cargo policy is designed to pay.

A standard MTC policy is written for domestic over-the-road freight with typical bill of lading liability limits as a baseline. Intermodal cargo arriving from overseas can be electronics, automotive components, or specialty goods with values that far exceed standard cargo sublimits. BMW Spartanburg plant freight, for example, involves high-value automotive parts where a single container load can represent hundreds of thousands of dollars in components. If the carrier's cargo policy has a sublimit for electronics or a per-occurrence cap that falls short of the contract requirement, the carrier is in breach of the shipping contract the moment they sign it and in a coverage gap the moment a claim occurs.

The conflict usually surfaces at claim time, not at contract signing. The shipper files a cargo claim, the carrier tenders it to their cargo insurer, and the insurer pays to the sublimit. The shipper then pursues the carrier for the balance. The carrier had no idea the sublimit existed because no one walked them through the policy form before they accepted the load.

For SC drayage insurance purposes, every cargo policy placed on an inland port account needs to be reviewed against the actual shipping contracts the carrier is signing, not just against generic market standards.

Upstate SC Rate Territory: How Greenville and Spartanburg Affect Your Premium

Underwriters do not treat South Carolina as a single rating territory, and carriers based in the Upstate find out quickly that their location influences their premium in ways they did not anticipate.

The Greenville-Spartanburg metro sits at the convergence of I-85 and I-26, with I-385 cutting through Greenville and I-585 serving Spartanburg. The freight density on those corridors is high, driven by the BMW plant, the Michelin manufacturing presence, and dozens of automotive and industrial suppliers. High freight density means high truck miles, and high truck miles mean more loss experience for underwriters to work with. The I-85 corridor from the Georgia line through Spartanburg into North Carolina is one of the heavier loss corridors in the Southeast.

Carriers based in Spartanburg County or Greenville County who run to Inland Port Greer are operating in a territory that underwriters watch closely. A clean loss history is especially important here because the territory surcharges are real. Carriers with even one at-fault accident in the past three years may find that Upstate SC classification pushes them out of preferred markets entirely.

The other factor that affects premium at renewal is radius. Carriers running drayage from Greer to Charleston are running roughly 250 miles one way. That puts them in a different radius class than purely local drayage operators, and it changes how underwriters assess exposure. If your actual operating radius does not match what's on your policy, you have both a rating problem and a potential coverage dispute waiting to happen.

What to Check Before You Accept an Inland Port Load

Accepting a drayage move to or from Greer or Dillon without running through a quick coverage check is how carriers end up paying out of pocket for losses that should have been insured. The following items are not a substitute for a full policy review, but they are the questions that surface problems most often.

First, confirm your liability policy form covers intermodal drayage and does not exclude operations where you are working under a third party's authority or as a subhauler to an intermodal intermediary. The exclusion is sometimes buried in an endorsement, not in the main form.

Second, check whether your policy includes chassis interchange coverage with an adequate limit. If you are pulling a chassis from the SCPA pool or from a shipping line's chassis fleet, you need that coverage in writing on the policy, not as an assumption.

Third, pull the cargo sublimits from your MTC policy and compare them against the cargo contract you're signing. Pay specific attention to per-occurrence limits, electronics sublimits, and any named-perils restrictions that could limit recovery on the specific freight you're hauling.

Fourth, confirm your authority is appropriate for the move. Carriers operating intrastate drayage within South Carolina need to meet SCDOT motor carrier requirements for intrastate operations. If the move crosses state lines, your interstate FMCSA authority must be in order and must match the authority your insurer filed with the MCS-90.

Fifth, verify that the certificate of insurance you provide to the shipper or broker matches what the contract requires. A certificate that lists the wrong additional insured or omits a required endorsement creates a contractual default even if your underlying coverage is technically in place.

For a broader review of the base requirements before you operate in the state, South Carolina commercial truck insurance requirements are a starting point, but inland port drayage work layers additional requirements on top of the baseline.

How TB Insurance Handles Intermodal and Inland Port Accounts in SC

TB Insurance Group places intermodal drayage accounts in South Carolina differently than standard OTR trucking accounts, because the underwriting questions are different and most standard trucking markets are not the right fit for this work.

The process starts with understanding what the carrier actually does at the ports. That means getting specifics: what chassis sources they pull from, what contracts they sign with BCOs or intermodal intermediaries, what freight commodities move through their operation, and what their actual operating radius looks like on a week-to-week basis. A carrier running local drayage within a 50-mile radius of Greer is a different underwriting submission than a carrier running Charleston turns twice a week.

With that information, the team identifies carriers among TB Insurance's 25-plus carrier relationships who have actual appetite for inland port drayage in South Carolina. That is not a long list. Most standard trucking markets either exclude drayage operations outright or write them in a way that leaves coverage gaps the carrier won't discover until a claim. Finding the market with the right form, the right endorsements, and the right appetite for Upstate SC territory is the core of the placement work.

On every policy placed for inland port accounts, the team requires chassis interchange coverage be explicitly confirmed on the endorsement schedule, cargo limits and sublimits be reviewed against the carrier's actual shipping contracts, and the policy territory and radius classification match what the carrier is actually running. These are not optional checks. They are the baseline for every submission that goes out the door.

If you are hauling to Greer or Dillon and you have not had someone walk through your current policy with inland port drayage specifically in mind, the coverage you think you have may not be the coverage you actually have. Get a coverage review and find out before the claim does.

Frequently Asked Questions

Does a standard FMCSA trucking policy cover drayage at Inland Port Greer or Inland Port Dillon?

Not automatically. Standard OTR trucking policies are written around carriers operating under their own authority with their own bill of lading. Drayage at SC inland ports often involves pulling under an intermodal intermediary's authority, hauling under an ocean bill of lading, and operating equipment you don't own. Some policy forms exclude those arrangements by endorsement. You need a form that explicitly names drayage and intermodal operations as covered work before you pull the first load.

Who is responsible for chassis damage at SCPA inland ports if the chassis belongs to a leasing company?

That depends on the interchange agreement you signed, the chassis provider's damage liability terms, and whether your policy includes non-owned trailer or chassis coverage with an intermodal endorsement. Most primary trucking policies do not automatically extend to chassis you pull from a pool. If the chassis comes back damaged and your policy form excludes non-owned equipment or intermodal equipment specifically, the repair bill lands on you out of pocket.

What insurance certificates do shippers and BCOs typically require from drayage carriers serving Greer and Dillon?

Requirements vary by beneficial cargo owner and intermodal intermediary, but most want primary auto liability at or above $1 million, motor truck cargo coverage with limits matching the commodity value, and general liability. Some steamship lines and large BCOs also require them to be named as additional insureds with specific endorsement language. A certificate pulled from a standard OTR policy often does not match those requirements, which can delay a load or disqualify you from a lane entirely.
