Not Just Carriers: How Section 301 Tariff Shifts Raise Costs for Every Link in the Chain

Trump’s new port fee policy has drawn headlines for its impact on vessel operators — but the ripple effects could reach far beyond shipowners. For logistics service providers (LSPs), importers, and exporters, the changes under Section 301 tariffs are setting the stage for higher costs, tighter capacity, and renewed compliance headaches.

What Happened

On October 14, the U.S. Trade Representative (USTR) began enforcing new Section 301 port fees targeting vessels classified as roll-on/roll-off (Ro/Ro) carriers. The rules, originally introduced during the Biden administration’s investigation into Chinese port equipment, were implemented under the Trump administration with last-minute changes that widened their reach.

The first major casualty was Atlantic Container Line (ACL), a U.S.-based carrier operating five hybrid vessels on the transatlantic route. These ships carry roughly 80% containers, 10% Ro/Ro cargo, and 10% oversize freight. Yet under the new classification, ACL’s vessels are now defined as “Ro/Ro container ships” — and are therefore subject to tonnage-based fees rather than container-based ones. The result: an estimated $34 million annual tariff burden for ACL.

ACL CEO Andrew Abbott told CNBC that this classification makes the company’s U.S. operations “nonviable,” warning that it may have to withdraw services or relocate operations abroad if the rule stands.

Why It Matters for Logistics Service Providers

The rule might appear limited to vessel owners, but its effects will cascade through the supply chain. Forwarders, 3PLs, and cargo owners all stand to face the consequences as carriers adjust to the new cost reality.

1. Freight Rate Pass-Through

Carriers absorbing new tariffs will likely add surcharges or adjust contract rates to recover losses. Transatlantic trades — especially between Northern Europe and the U.S. East Coast — could see higher base freight rates or new “port recovery” fees embedded into 2026 contracts.

2. Capacity and Schedule Risks

ACL’s five-vessel service ensures weekly frequency for containerized, oversized, and breakbulk shipments — a rare capability on the Atlantic lane. If the company scales back or exits, LSPs and shippers may face reduced slot availability and longer lead times, forcing greater reliance on chartered tonnage or multi-leg routing.

3. Specialized Cargo Disruption

ACL’s hybrid vessels handle cargoes that few others can — such as factory machinery, oversized project components, or automotive assembly equipment. Losing this service would limit flexible shipment options for industrial and manufacturing clients, driving up costs for charter or breakbulk alternatives.

4. Contractual and Compliance Exposure

Section 301 actions are inherently political and can shift with minimal notice. LSPs managing U.S.-linked trade need to monitor classification risks and tariff pass-through clauses in contracts. Even if current clients aren’t directly exposed, future rule changes could target other vessel types or service categories.

5. Client Communication Challenges

Many shippers assume tariffs only apply to import duties. When carriers introduce new surcharges, LSPs often bear the brunt of customer confusion. Clear communication about how Section 301 enforcement affects freight pricing will be essential to preserve client trust and avoid margin erosion.

Industry Reaction and Outlook

Abbott has described the situation as “another straw that’s going to break the camel’s back” amid an already weak freight environment. Industry observers note that the rule change runs counter to U.S. policy goals of supporting domestic operators — ACL is the only major carrier with U.S. headquarters on the transatlantic trade.

The USTR, for its part, has defended the program, stating that classification follows the International Classification of Ships by Type (ICST), which is based on vessel construction rather than use. That means hybrid ships like ACL’s are treated as Ro/Ro vessels regardless of their primary cargo.

Unless the USTR grants an exemption or revises its interpretation, U.S. importers, exporters, and LSPs should prepare for a period of elevated cost and uncertainty across certain Atlantic trades.

How LSPs Can Prepare

Audit contracts for exposure to tariff pass-through clauses or reclassification risks.
Reassess routing options and identify alternate carriers or transshipment paths for critical cargo.
Use visibility platforms like TRADLINX to track port calls, service shifts, and rate adjustments in real time.
Communicate early with clients about potential surcharges and service impacts to manage expectations.

Bottom Line

Section 301’s port fee overhaul was intended as a trade enforcement measure — but its blunt application risks penalizing the very operators and customers it was meant to protect. For logistics service providers, the episode underscores a familiar truth: policy changes rarely stop at the pier. The smarter LSPs will treat this as a signal to strengthen rate tracking, diversify carriers, and prepare clients for a cost environment increasingly shaped by politics as much as performance.

Turn policy risk into negotiation leverage. TRADLINX visibility data helps LSPs model real costs and benchmark carriers before signing 2026 contracts.
