When Trade Lanes Move: Staying Compliant and Competitive as Global Flows Shift

Over the past two years, some of the world’s most critical corridors have been disrupted, rerouted, or closed entirely. When supply chains adapt, compliance fluidity is where commercial advantage is gained.

When the Route Changes, the Compliance Exposure Can Change with It

The Red Sea crisis is the clearest recent example of how fast an established trade corridor can break down, with container ship traffic through the Suez Canal falling by 90% in 2024.

As a result, freight rates between Shanghai and Rotterdam were around 80% higher in 2025 than before the crisis began. Rerouting ships around Africa’s Cape of Good Hope also added roughly 30% to transit times.

To compound the issue further, the extended transit times removed approximately 9% of effective global container shipping capacity. These figures apply to container shipping specifically; the impact on bulk carriers and tankers was smaller.

The result was that – just as carriers had finally gained some stability after Covid lockdowns – vessels once again began diverting to different ports to try and stabilise liner schedules.

• The African route caused many vessels to bypass their usual northern European hubs.
• Mediterranean ports lost direct calls and were served instead by feeders from southern Spain and Morocco.
• Hamburg, Bremerhaven, and Wilhelmshaven absorbed volumes that would normally clear through Rotterdam or Antwerp.

Beyond the initial shipment, carriers also face an equipment challenge. When 1,000 containers are discharged and restituted at a port which has no export service, those containers require another vessel or lease agreement to be brought back into circulation.

For importers, the shift is more than a logistics problem. Deferment accounts, broker agreements, pre-lodgement arrangements, and bonded warehouse links can be tied to specific territories or ports.

Being set up to clear at Rotterdam does not mean you are set up to clear at Hamburg. And, depending on your shipment, there can be cash flow and tax considerations.

The Strait of Hormuz: When There Is No Bypass

The Red Sea had a workaround. The Cape of Good Hope route added time and cost, but cargo kept moving. The Strait of Hormuz does not have an equivalent. The Strait is the only sea passage out of the Persian Gulf. When it closes, cargo stops.

The Gulf handles around 33 million TEUs of container traffic each year across the UAE, Saudi Arabia, Kuwait, Qatar, and Bahrain. Jebel Ali in Dubai, alone, processes approximately 15.5 million TEUs annually.

And, the Strait is not the only waterway affected in the region. Military activity and the withdrawal of insurance for war risk by insurers has widened the area of effect.

Although primarily affecting energy and container vessels, the effects on supply chains include other modes. The Middle East is a key airfreight region, already navigating increased volumes since the closure of the Suez Canal.

The suspension of sea and air activity in the region results in other lanes absorbing the volume, or goods are sourced from elsewhere. If your business cannot pivot their customs activity or your procurement officers are unable to verify materials, preference, or other considerations quickly, then your contingency plan carries a higher risk.

Northwest European Ports: When Contingency Clearance Becomes the Plan

The disruptions above are driven by events far from Europe. The delays that hit Rotterdam and Antwerp in October 2025 were local. In some ways, they were more instructive, because they are part of a recurring pattern.

Antwerp was Europe’s busiest container port in Q1 of 2025, ahead of Rotterdam. In October, both were disrupted at the same time. Rotterdam’s lasher workers walked out over a pay dispute, bringing container terminal operations to a halt. At Antwerp, harbour pilots restricted their hours to protest pension reforms, cutting daily vessel movements in half.

The usual contingency – divert from one port to the other – was not available. Antwerp’s throughput fell to 31 vessels a day against a normal 60-80. More than 100 ships were waiting offshore.

And, to compound the issue, these events did not happen in isolation.

French ports faced strikes throughout early 2025. Low water on inland waterways restricted barge movements across the continent. Road and rail networks were under sustained pressure.

Across Northwest Europe, congestion, industrial action, weather, and infrastructure limits are now overlapping risks rather than separate incidents.

All of this came at a time of record Asia-Europe volumes in Q1.

The question for importers and exporters is not whether a forced diversion will happen. It is whether you are ready when it does. Cargo sent to Hamburg, Bremerhaven, or Le Havre at short notice lands at a port where many businesses have no active deferment cover, no broker relationship, and no pre-lodgement in place.

The freight forwarder handles the operational diversion. The customs gap falls to whoever picks it up under pressure. Businesses with multi-port coverage already in place do not have that problem. Those without it improvise, and improvised customs clearance is where delays begin to incur costs, or where audit exposure starts.

When Ocean Freight Becomes Air Freight

When ocean routes fail, the default response for time-sensitive goods is to move them by air. That decision has compliance consequences that are often missed in the rush to rebook cargo.

The current Gulf situation has made this harder in a way that is new. Dubai and Abu Dhabi are not minor waypoints on the Asia-Europe air freight network. They are two of its main hubs for transshipment and consolidation.

When the Strait of Hormuz closed in late February 2026, multiple Gulf states announced airspace closures at the same time. The European Aviation Safety Agency extended its conflict zone bulletin across eleven countries in the region. Dubai and Abu Dhabi airports moved to limited operations, handling domestic carriers and approved cargo flights only.

The modal fallback that businesses used during the Red Sea crisis – shift to air through Gulf hubs – was no longer available. Ocean and air were both constrained in the same region simultaneously.

That combination is without recent precedent, forcing procurement and routing changes that require ongoing customs supervision as contingencies are found and executed.

What Changes When Goods Move by Air

A commodity code is likely to stay the same when goods switch from one sea lane to another, providing nothing changes with the goods. A container of product from one origin may require different documents, have different rules of origin, or a different import duty rate, but the code is less likely to change.

However, goods that normally travel by sea in full container loads may be repacked or split into smaller quantities for air. A change in quantity or presentation can push goods into a different tariff heading. That needs to be checked, not assumed.

Beyond goods classification, valuation methods, entry timelines, and clearance procedures all differ between modes. A business that clears goods by sea through an established broker, on a regular deferment cycle, has a setup built for that mode.

When the same goods move by air, that setup does not carry over. The shipment is often through a different forwarder, with declarations completed quickly and under pressure to avoid storage fees. The errors that result tend to surface at audit rather than at the border, by which point the liability has already built up.

Changing Trade Lanes: New Routes, New Suppliers, New Agreements

Not every change is driven by crisis. Some trade lanes are shifting because of new infrastructure, new sourcing decisions, or new agreements.

These changes carry the same compliance implications, but they also carry a commercial opportunity for businesses that move first.

New Corridors: The Arctic Liner Route

In September 2025, Chinese operator Haijie Shipping launched the first regular container service via the Northern Sea Route. It connects Chinese ports to Rotterdam, Hamburg, and Gdansk, cutting transit time by around 40% compared to the Suez Canal route.

The route is seasonal, running roughly from late July to early November. It passes through Russian-controlled waters, which limits access for many Western operators.

Therefore, it is not yet a mainstream option, but some Chinese shippers are already using it to deliver goods to European ports.

If Hamburg or Rotterdam are blocked in the later end of the Arctic route’s season – during the lead up to Christmas – then diversion of Northwest European cargo to Gdansk can have real implications. At that point, delays in clearance could mean missing a key delivery window.

The time to build the right procedures is before a problem arrives, not after.

New Suppliers: The China+1 Shift and Circumvention Risk

The instability during Covid, amongst other considerations, pushed many European importers to create sourcing contingencies in Vietnam, India, South Korea, and other markets.

By 2024, around 73% of the EU’s clean technology imports still came from China.

The US tariffs of 2025 redirected more Chinese exports toward Europe, increasing price pressure and supply concentration at the same time. The EU introduced anti-dumping and countervailing duty measures across steel, electric vehicles, and clean technology goods to dam the sudden inflow.

In practice, this forced importers to procure these goods from other origins so that they could avoid increased landed costs.

Switching supplier does not automatically solve the duty problem, though. EU anti-dumping investigations have found repeatedly that Chinese inputs assembled or processed in a third country do not change the origin of the finished product – as a UK importer of aluminium foil discovered when they received a £4.7 million bill for underpaid duty.

Therefore, an importer who switches to a Vietnamese or Indian supplier without checking the origin chain may have moved the risk, not removed it.

Air cargo volumes on the Vietnam-to-Europe apparel route spiked 62% in a single week in January 2024, as importers moved goods off disrupted ocean lanes in a hurry. The same origin verification obligations applied to every one of those shipments. Speed does not suspend compliance requirements.

South Korea has emerged as a genuine China+1 sourcing option for some products, and it has an EU free trade agreement. This is why CSG has a partner in South Korea, helping us to support compliance across both regions so that you can minimise your risk.

In every case, the answer is the same: verify the origin of the new supply chain before the first shipment moves, not after the first query from customs.

New Agreements: EU-Mercosur, CETA, and the Preference Gap

The EU-Mercosur Partnership Agreement and Interim Trade Agreement were signed on 17 January 2026, after more than 25 years of negotiation. The Interim Trade Agreement does not need to be ratified by individual EU member states, so it can apply ahead of full parliamentary approval.

When in force, it will cut or remove tariffs on cars currently facing up to 35% duty in Mercosur markets, machinery at 14-20%, and pharmaceuticals at up to 14%.

For EU importers, the agreement opens up Mercosur-origin raw materials and agricultural inputs at lower rates. The EU currently imports 82% of its niobium – used in MRI scanners and cancer treatment equipment – from Mercosur countries.

In both directions, the saving is not automatic. Preferential rates require correct goods classification, compliant origin declarations, and supplier documents that most European businesses have not yet set up. The businesses that prepare early capture the benefit from day one. Those that wait keep paying full duty rates whilst competitors do not.

The Comprehensive Economic and Trade Agreement (CETA) has been in provisional application since 2017. By 2021, CETA preference use among Canadian exporters had reached 65% – up from 52% in 2018.

That still left more than a third of eligible exports not claiming the rate they were entitled to. In sectors like nickel, railway equipment, and copper, use was in the single digits years after the agreement came into effect.

That unclaimed preference is recoverable duty cost. Recovering it requires the classification and origin work that makes the claim defensible. The same pattern will repeat with EU-Mercosur. The question is whether your business is ready to capitalise whilst others don’t.

Why This Matters for Your Business

Every example in this article comes down to the same situation. A business built its customs setup around a fixed set of assumptions: a specific port, a specific supplier, a specific route, a specific mode. Then the world moved. The logistics adapted. The compliance did not.

That gap has a direct cost. It shows up as:

• Duty paid on goods that qualified for a preferential rate, but lacked the paperwork to claim it.
• Audit findings on entries made under pressure when cargo arrived at the wrong port.
• Anti-dumping liability on goods from a new supplier whose origin was assumed rather than checked.

It also presents as competitive disadvantage. The businesses that minimised disruption costs or captured savings on day one of a new trade agreement did so because they built the right infrastructure before the agreement came into force.

Those that did not kept paying full rates whilst their competitors moved ahead.

The businesses with the least exposure are not the most cautious ones. They are the ones with the most responsive compliance setup – one that moves when trade lanes move, and that finds the commercial opportunity in each change rather than just absorbing the cost.
