Tariffs at Sea: What Freight Forwarders Need to Know

What’s inside?
For ocean freight forwarders, tariffs are not abstract policy tools. Every new duty or exemption can disrupt sailing schedules, alter customer demand, and reshape contract economics. In recent months, tariff changes have even led shippers to cancel or postpone shipments, demand contract renegotiations, and rethink their long-term relationships with logistics partners.
With margins already razor-thin, forwarders cannot afford to treat tariffs as an occasional nuisance. Instead, they must embed tariff resilience into the heart of their operations. As FIATA recently emphasized, today’s shifting trade dynamics are forcing companies to build stronger collaboration and regional adaptability, recognizing that tariffs are just one lever in a larger landscape of geopolitical and economic pressures.
To navigate this volatility, forwarders should focus on five interconnected areas: market intelligence, contract management, routing flexibility, compliance readiness, and customer communication.
Market Intelligence: See the Shifts Before They Hit
Tariff announcements don’t happen in isolation. They ripple through the entire ocean freight market. As Xeneta has highlighted, new duties between the U.S. and China have repeatedly triggered “Liberation Day” spikes and sudden collapses in spot rates, creating waves of uncertainty for both shippers and forwarders.
The challenge is that tariffs don’t just add cost to importers; they alter demand patterns. Some shippers frontload cargo to avoid new duties, distorting seasonal flows. Others divert to alternative origins, forcing carriers to adjust vessel deployments. The result is volatile rates, unexpected blank sailings, and a planning puzzle for forwarders.
To stay ahead, forwarders need to continuously track:
- Spot and contract rate trends – so they can anticipate cost swings before customers feel the impact.
- Carrier reactions – such as GRIs or blank sailings in response to tariff-driven demand shifts.
- Geopolitical signals – trade negotiations, tariff reprieves, or retaliations that may trigger sudden shifts.
Logistics companies that systematically monitor tariff-related trends, and model their downstream effects on freight flows, are better equipped to provide stability to customers and protect margins, as BCG recently noted.
Contract Management & Visibility: Turn Complexity Into Clarity
Tariff changes expose a painful truth in freight forwarding: most contracts are not built for volatility. Buy- and sell-side agreements often assume stable cost structures, leaving forwarders either absorbing unexpected duties or scrambling to renegotiate after the fact.
IIFA warns that global tariff strategies increase the risk of “errors and omissions,” especially when forwarders lack visibility into which contract terms apply to which shipment. Misapplied terms don’t just erode profit — they can damage customer trust and lead to costly disputes.
The solution lies in contract management and full visibility. Forwarders should:
- Maintain structured contract breakdowns that detail every tariff, surcharge, and validity period, such as working with contract management tools.
- Provide operational teams with shipment-level visibility into applicable terms, so they can quickly explain charges to customers.
- Use contract transparency as a tool for customer communication — showing clients exactly how tariffs affect their shipments, and what mitigation strategies are possible.
By linking tariff clauses directly to container movements, forwarders not only prevent revenue leakage but also empower teams to plan proactively and manage customer expectations with confidence.
Routing Flexibility: Build Options Into Every Plan
Tariffs don’t just raise costs; they redirect trade flows. When U.S. duties on Chinese goods rose in recent years, shippers rerouted through Southeast Asia or Mexico to take advantage of different tariff regimes.
These shifts can happen overnight. A tariff reprieve might unleash a rush of bookings, while a new duty might suddenly make a lane uncompetitive. Forwarders that rely on a single routing or fixed capacity risk being blindsided.
Instead, resilience requires:
- Alternative port and routing options – maintaining relationships and capacity access across multiple corridors.
- Scenario planning – preparing contingency plans for tariff changes, including volume swings and customer rerouting requests.
- Customer education – explaining the trade-offs between cost, duty exposure, and transit times when alternative routes are required.
As FIATA has observed, regional collaboration is becoming increasingly important. Forwarders who can flexibly shift between trade corridors — while maintaining service quality — will be better positioned to win business in tariff-driven markets.
Compliance Readiness: Stay Accurate, Stay Trusted
Compliance is where tariffs meet reality. Every new duty requires accurate classification, updated documentation, and consistent audit trails. A single misstep — a wrong HS code, an outdated tariff rate, or a missing log — can lead to fines, delays, or reputational damage.
The IIFA highlights that the pace of tariff changes is the greatest challenge, leaving operators exposed to errors if they lack up-to-date references.
To remain compliant and credible, forwarders should:
- Maintain updated tariff tables that reflect the latest duties and exemptions.
- Keep detailed audit logs for all tariff applications, ensuring disputes can be resolved quickly.
- Build in-house expertise – staff trained to interpret tariff changes, update processes, and communicate with customs authorities and customers alike.
Compliance is more than paperwork; it is a foundation of trust. Shippers need to know their forwarder won’t expose them to regulatory risk.
Customer Communication: From Reactive to Proactive Partner
Perhaps the most underestimated impact of tariffs is on customer relationships. A sudden duty can push customers to cancel shipments, postpone orders, or demand renegotiation. How a forwarder communicates in these moments determines whether the relationship is strengthened or lost.
Freight forwarders have stressed that it’s crucial to develop clear, consistent language to explain tariff impacts — not just to operations teams, but to shippers who may be unfamiliar with the intricacies of trade policy.
The goal is not only to react, but to anticipate. Forwarders should:
- Proactively update customers when tariff changes are announced, outlining the likely operational and financial impacts.
- Provide scenario-based guidance, showing alternative routes or cost structures under different tariff outcomes.
- Reassure customers that the forwarder is not just processing shipments, but actively monitoring policy and planning responses.
In a volatile tariff environment, customer communication becomes a differentiator. As Xeneta noted in its analysis of tariff ripple effects, shippers value forwarders who can translate market chaos into clear, actionable insights.
From Turbulence to Trust
Tariffs will continue to shape the ocean freight market — sometimes predictably, often not. What matters for forwarders is how they respond. By embedding resilience across market intelligence, contract management, routing, compliance, and customer communication, forwarders can transform tariffs from a threat into an opportunity.
- See sooner: Monitor rate movements and policy announcements before they hit customer costs.
- Plan smarter: Use contract visibility and routing flexibility to keep operations agile.
- Stay compliant: Maintain updated tariff knowledge and audit trails.
- Communicate clearly: Build trust by being proactive, transparent, and consultative with customers.
As FIATA put it, navigating today’s trade dynamics demands collaboration and adaptability across the logistics ecosystem. Forwarders who embrace these priorities can safeguard their margins while strengthening customer trust in an era where tariffs have become the new normal.
