Introduction
Middle East maritime disruption is changing how some major Chinese energy shippers move cargo. Reuters reported on August 18, 2026 that COSCO Shipping Energy Transportation and China Merchants Energy Shipping had kept their tankers out of both the Strait of Hormuz and Bab al-Mandeb since late July, instead using loadings and ship-to-ship transfers outside the Gulf. The companies had previously handled roughly half of China’s crude imports from the Middle East, making their response a meaningful signal of how serious operators are managing route risk.
For overseas companies sourcing from China, however, the lesson is not that every container vessel serving China will follow the same route. Crude tankers, container ships, bulk vessels and feeder services have different networks, contracts and operating constraints. The buyer-relevant lesson is narrower and more practical: when major chokepoints become unreliable, freight assumptions can change quickly, and procurement teams should verify route exposure rather than relying on normal transit-time and surcharge expectations.
As of August 21, Reuters reported that only seven commodity ships had passed through Hormuz on the prior day and that no VLCC or LNG tanker was among them. Conditions are therefore highly fluid. Buyers planning China-related shipments should treat route, price and lead-time information as time-sensitive inputs that need to be rechecked close to booking.
What changed in the Middle East shipping picture
Reuters’ August 18 report said the two Chinese state-controlled tanker groups had avoided Hormuz and Bab al-Mandeb since late July. Instead of entering the highest-risk areas, vessels were loading crude through ship-to-ship transfers around Fujairah and Omani ports or using alternative loading arrangements.
The operational effect was not simply “take another route.” Longer voyages, more waiting time and greater uncertainty reduced vessel utilization. Reuters reported that daily freight assessed for the Oman-to-China voyage had risen sharply, while vessels were also being redirected toward alternative loading points. One COSCO tanker that had intended to load Saudi crude in the Red Sea instead sailed through Suez without cargo and loaded at Egypt’s Mediterranean port of Sidi Kerir.
These examples concern oil logistics, but they illustrate a general supply-chain principle: a chokepoint disruption can change where cargo is loaded, where ships wait, which legs require transfer, how long assets are tied up and which party bears additional cost. For a China-sourcing buyer, those effects may show up indirectly through fuel surcharges, carrier capacity, insurance, feeder schedules, transshipment congestion or supplier delivery commitments.
Why China-sourcing buyers should care without overgeneralizing
The Strait of Hormuz and Bab al-Mandeb are not on every China container route. A shipment from Shenzhen to Los Angeles, for example, does not normally depend on either chokepoint. A shipment from China to parts of Europe, the Mediterranean, the Middle East or East Africa may have different exposure depending on the carrier service, port pair and routing.
The practical risk is therefore not “Middle East disruption equals all China freight disruption.” The risk is assuming a route is unaffected without checking the specific service being booked. Even when the vessel does not cross a disrupted strait, network effects can matter because carriers redeploy ships, change rotations, omit ports, add transshipment steps or adjust surcharges across a broader network.
Buyers should separate three questions: whether the booked service physically crosses or depends on a high-risk waterway; whether the carrier has changed its network because of the disruption; and whether the supplier or forwarder is passing additional cost or time into the shipment. Each requires evidence rather than a generic yes-or-no answer.
1. Map the actual route before accepting a freight quote
Start with the origin, destination, carrier service and expected transshipment ports. Ask the forwarder to identify the normal route and the currently planned route, including whether the service depends on Hormuz, the Red Sea, Bab al-Mandeb, Suez or an alternative passage.
For container cargo, do not rely on a broad statement such as “via Suez” or “Middle East service.” Request the carrier service name and expected port rotation where available. If the cargo is transshipped, identify the first and second vessel legs rather than looking only at the final destination.
The goal is not to predict every ship movement. It is to understand which assumptions drive the quoted transit time. If one chokepoint or transshipment hub is unavailable, ask what the carrier’s alternative is and how many days that alternative normally adds.
For urgent or high-value cargo, record the route assumption in the quotation or booking note so that a later change can be compared against what was originally offered.
2. Ask what has changed since the last normal sailing
A freight quote can look normal even when the operating environment is not. Ask the forwarder or carrier what has changed in the last one to two weeks: vessel routing, port calls, blank sailings, transshipment hubs, security restrictions, war-risk premiums, bunker surcharges or documentation requirements.
This is especially important during fast-moving disruption because historic transit times may no longer describe current performance. A supplier may still quote its usual “30–35 days” because that is the lead time stored in its sales template, while the carrier is already operating a different rotation.
Ask for the latest carrier notice or booking confirmation when the route change materially affects delivery. If the forwarder cannot support a new surcharge or transit estimate with a carrier communication, rate sheet or booking evidence, treat the figure as provisional.
3. Validate surcharges instead of accepting one unexplained number
During disruption, buyers may encounter war-risk surcharges, emergency surcharges, bunker adjustments, congestion fees, feeder premiums or revised peak-season charges. A higher freight quote may be legitimate, but the buyer should understand what changed.
Request a simple breakdown: base ocean freight, origin charges, destination charges and any disruption-related additions. Ask whether the surcharge is carrier-imposed or forwarder-imposed, whether it applies per container or per bill of lading, and how long the quoted rate is valid.
For repeat orders, compare the new quote with the previous shipment on the same lane. A large increase should be explained by a documented change in carrier pricing, routing or capacity rather than only by the phrase “Middle East situation.”
Where practical, obtain two or three comparable quotes using the same shipment assumptions. Differences can reveal whether one provider has better carrier access, a different route or simply a different risk premium.
4. Separate carrier transit time from supplier lead time
When disruptions occur, suppliers sometimes add a general buffer to the entire order and describe the result as “shipping delay.” Buyers should separate production readiness from transport delay.
Ask the supplier for the factory-ready date or cargo-ready date independently from the vessel departure estimate. Then ask the forwarder for estimated booking time, cut-off, departure, transshipment and arrival. This creates a timeline that makes the actual source of delay visible.
For example, a seven-day shipping buffer should not conceal a four-day production slip plus a three-day booking delay. Separating these elements helps buyers decide whether to expedite production, choose another carrier, split the shipment or simply accept a longer route.
This also protects supplier-performance measurement. A factory that delivered on time should not automatically be penalized for a carrier rerouting decision, while a factory that finished late should not be able to attribute the whole delay to geopolitics.
5. Build delivery buffers around the failure points that actually exist
A useful contingency buffer is based on specific failure points, not a random number of extra days. Consider booking availability, port cut-off changes, transshipment waiting, route diversion, customs processing, final-mile delivery and possible port congestion.
If a service now requires an additional transshipment, the buyer may need more buffer than if the carrier simply sails a longer direct route. If the shipment is time-sensitive, ask whether alternative departure ports or nearby destination ports would reduce reliance on a vulnerable connection.
For project cargo or production-critical components, consider splitting volume. A portion can move on the lowest-cost route while a smaller emergency quantity uses a faster or more resilient option. The extra cost should be compared with the cost of production downtime or customer delay rather than with ocean freight alone.
Avoid applying the same buffer to every shipment. A routine replenishment order and a line-stopping component have different tolerance for delay and justify different contingency plans.
6. Review insurance, war-risk treatment and responsibility for route changes
When security risk rises, transport insurance and carrier terms can change. Buyers should confirm what the cargo policy covers and which party is responsible for arranging insurance under the agreed Incoterm.
Ask the insurer, broker or logistics provider whether the planned route triggers any war-risk exclusion, additional premium or notification requirement. Do not assume that standard cargo insurance automatically covers every conflict-related delay, diversion or seizure scenario.
Also distinguish physical cargo loss from commercial delay. Many cargo policies focus on loss or damage and may not compensate the buyer for late delivery, lost sales or production downtime. If delay cost is material, the commercial contract may need its own treatment.
Where the seller controls freight, confirm whether the contract allows the seller to change carriers or routes without approval and how additional freight is handled. Where the buyer controls freight, document who approves a route change and who receives carrier disruption notices.
7. Use route scenarios instead of one fixed transit-time promise
In unstable conditions, a single transit-time number can create false confidence. A better planning approach is to use at least three scenarios: current expected routing, a moderate diversion or transshipment delay, and a severe disruption case requiring a materially different service.
For each scenario, estimate total door-to-door time and incremental cost. The numbers do not need to be perfect. Their purpose is to show management which customer commitments, inventory levels or production schedules become vulnerable if the route changes.
For example, a procurement team may decide that normal inventory covers the expected route but not a severe case. That gap can justify earlier ordering, a second source, safety stock or a partial airfreight contingency.
Update the scenarios when carrier notices or booking results change. In a fluid situation, a plan created three weeks earlier can be less reliable than a fresh booking check.
8. Ask suppliers whether higher logistics costs are entering product prices
Freight disruption can affect suppliers even when the buyer books the outbound shipment. Chinese factories may import energy, metals, chemicals or components whose own logistics costs have changed. A supplier may therefore seek price increases or shorter quotation validity.
If a supplier cites freight or energy disruption as the reason for a product-price change, ask what input is affected and whether the increase is temporary, indexed or permanent. The buyer does not need the supplier’s full cost structure, but should understand whether the claim relates to inbound material freight, fuel, outbound logistics or a general risk allowance.
For long-term orders, consider separating product price from unusually volatile freight elements instead of allowing one opaque all-in price to move repeatedly. This makes later normalization easier if transport conditions improve.
The same logic applies to minimum order quantities and payment terms. A supplier facing longer inbound lead times may increase inventory requirements. Buyers should distinguish a documented supply-chain constraint from an unrelated commercial renegotiation.
9. Keep Incoterms and booking responsibility clear
Disruption increases the importance of knowing exactly where responsibility changes hands. Under EXW, FOB, CIF, DDP and other terms, the parties may control different parts of the journey and carry different cost and risk responsibilities.
Do not use an Incoterm as shorthand for the entire logistics agreement. Record the named place or port, the agreed Incoterm version, who books the main carriage, who pays disruption surcharges, who arranges insurance and who approves a route change.
If the supplier quotes both EXW or FOB and an all-in delivered option, compare them under the same disruption assumptions. A delivered price can be convenient, but the buyer should still know which carrier and route the supplier intends to use.
Clear responsibility is especially important when a shipment is already in transit. If the carrier changes route or holds cargo, both parties should know who communicates with the forwarder, who can authorize additional cost and how customer delivery commitments will be updated.
Practical freight-planning checklist
For China-sourcing shipments during the current Middle East disruption, buyers should verify:
- The exact origin, destination, carrier service and expected transshipment points.
- Whether the booked service physically depends on Hormuz, Bab al-Mandeb, the Red Sea or Suez.
- Whether the carrier has changed its normal rotation, port calls or transit estimate.
- Whether any new surcharge is carrier-imposed, forwarder-imposed or only an estimate.
- The cargo-ready date separately from the booking and vessel-departure date.
- The latest booking lead time and space availability rather than historic averages alone.
- A moderate and severe delay scenario for critical shipments.
- Alternative ports, services or split-shipment options where practical.
- Cargo-insurance and war-risk treatment for the actual planned route.
- Which party controls routing and additional freight under the contract and Incoterm.
- Whether the supplier is passing higher inbound logistics or energy costs into the product price.
- Whether time-sensitive customer commitments need additional inventory or contingency stock.
Limitations and uncertainty
The primary Reuters reporting behind this article concerns crude-oil tanker operations, not the entire China container-freight market. COSCO Shipping Energy Transportation and China Merchants Energy Shipping are tanker operators, and their avoidance of Hormuz and Bab al-Mandeb should not be presented as proof that all COSCO-related container services or all China trade lanes are following the same policy.
The effect on a specific buyer depends on the exact origin-destination pair, carrier network, vessel type, transshipment plan, cargo urgency and contract terms. Some China sourcing lanes may have little direct exposure to the affected chokepoints, while others may experience indirect network or price effects.
Maritime conditions are also changing quickly. Reuters’ August 21 tracking showed Hormuz commodity-ship crossings still in single digits, but vessel movement, security restrictions, carrier policies and government positions can change within days. Buyers should recheck carrier notices, forwarder advice, insurance terms and booking availability close to shipment rather than treating this article as a live routing instruction.
Freight rates quoted in media reports, including tanker rates, are market snapshots and are not a benchmark for container freight. They illustrate how disruption can affect shipping economics, but should not be used to calculate a buyer’s container surcharge.
Conclusion
The most useful lesson from the current Hormuz and Red Sea rerouting is not that China-sourcing buyers should avoid a particular waterway by default. It is that route assumptions need to become an explicit part of procurement risk management when major chokepoints are unstable.
Major Chinese oil shippers are already demonstrating how operators can respond: move loading points, avoid high-risk passages, accept longer voyages and price uncertainty differently. Buyers should translate that signal into their own freight controls by mapping the actual service, validating surcharges, separating factory readiness from transport delay, checking insurance and responsibility, and maintaining realistic route scenarios.
That approach avoids two costly extremes: assuming normal schedules will continue unchanged, or overreacting as if every China shipment is equally exposed. The right question is specific and operational: what route is this shipment actually using, what has changed, and what will we do if that route changes again?

Research note: Reuters reports that COSCO Shipping Energy Transportation and China Merchants Energy Shipping have avoided Hormuz and Bab al-Mandeb since late July and shifted some crude-loading activity outside the Gulf. This article uses that behavior as a supply-chain risk signal, not as evidence that every container shipment or China trade lane is being rerouted in the same way. Freight and security conditions are time-sensitive and should be verified at booking.
