Amid sustained regional tensions involving the U.S., Israel, and Iran, shipping congestion in the Strait of Hormuz has persisted for over 40 days as of April 24, 2026. Rising global fuel prices are directly increasing cross-border logistics costs from China. Key express carriers—including ZTO Express, YTO Express, and J&T Express—have implemented or increased their bunker adjustment factor (BAF) on outbound parcels effective April 24, 2026. A 5–8% increase in maritime BAF is expected starting May 2026, impacting end-to-end logistics pricing and delivery reliability for global buyers sourcing from China.

Event Overview

On April 24, 2026, ZTO Express, YTO Express, and J&T Express announced adjustments to their bunker adjustment factor (BAF) for international parcel shipments. This follows more than 40 days of sustained shipping delays and rerouting in the Strait of Hormuz, driven by ongoing military-related disruptions in the region. The carriers confirmed the BAF increase applies to export parcels effective immediately; a further 5–8% hike in maritime BAF is scheduled to take effect in May 2026.

Industries Affected by Segment

Direct Trading Enterprises

Companies that directly import finished goods from Chinese suppliers face immediate pressure on landed cost calculations. Since BAF is typically passed through to shippers via freight invoices or platform-based rate cards, these enterprises may see revised quotes from logistics partners or e-commerce fulfillment platforms without prior notice. Impact manifests as reduced gross margins per order or unexpected cost overruns in pre-negotiated contracts tied to fixed freight terms.

Raw Material Procurement Enterprises

Firms sourcing components or raw materials—especially those with time-sensitive production schedules—may experience delayed replenishment cycles. While air freight remains an alternative, its higher baseline cost compounds the BAF impact. For commodities priced on CIF terms, upward BAF revisions may trigger renegotiation of Incoterms or lead to disputes over cost allocation if contracts lack fuel-surcharge clauses.

Contract Manufacturing & OEM Enterprises

Manufacturers fulfilling export orders under FOB or EXW terms bear limited direct exposure to BAF—but downstream clients increasingly request cost transparency and may push for shared mitigation strategies. Delays in vessel departures from Chinese ports (due to congestion-induced scheduling ripple effects) can indirectly affect factory dispatch planning and inventory turnover, especially for just-in-time supply chains.

Distribution & Channel Operators

Regional distributors, cross-border e-commerce sellers, and third-party logistics (3PL) providers managing multi-origin fulfillment must reassess routing efficiency and rate benchmarking. With BAF now applied across multiple carriers and likely to expand to other ocean freight forwarders, historical rate comparisons become less reliable. Variability in BAF application timing (e.g., parcel vs. LCL vs. FCL) adds complexity to quote accuracy and margin forecasting.

What Relevant Businesses Should Monitor and Do Now

Track official carrier announcements and contractual BAF clauses

Review current service agreements with ZTO, YTO, J&T, and other logistics providers for explicit BAF language—including calculation methodology, frequency of adjustment, and notification windows. Confirm whether BAF is applied uniformly across service tiers (e.g., standard vs. express) and destination zones.

Map exposure by shipment mode, origin port, and destination market

Identify which product categories or customer regions rely most heavily on sea freight from key Chinese ports (e.g., Ningbo, Shenzhen, Qingdao). Prioritize scenario planning for markets where maritime BAF increases will coincide with seasonal demand peaks (e.g., back-to-school or Q3 retail restocking).

Distinguish between policy signal and operational impact

The April 24 BAF update reflects a reactive cost pass-through—not a structural shift in capacity or routing. However, the scheduled May maritime BAF increase signals potential continuity. Monitor whether additional carriers announce similar measures, and whether any governments issue advisories affecting insurance, transit documentation, or port call priorities in the Gulf region.

Update procurement and communication protocols proactively

Where feasible, adjust purchase order terms to include fuel-surcharge contingencies. Notify downstream customers early if quoted delivery windows or landed costs are likely to change—particularly for long-lead or high-value orders. Document all BAF-related communications for audit and contract compliance purposes.

Editorial Observation / Industry Perspective

From an industry perspective, this BAF adjustment is better understood as a near-term cost signal rather than a systemic supply chain breakdown. It reflects direct price transmission from volatile marine fuel markets—not a collapse in vessel availability or port infrastructure. Analysis来看, the 40-day duration of Hormuz-related disruption is notable, but current rerouting patterns (e.g., Cape of Good Hope diversions) remain operationally viable, albeit at higher cost and longer transit times. Current更值得关注的是 whether this marks the beginning of recurring quarterly BAF volatility—or a one-off response to acute geopolitical stress. Observations suggest the latter for now, but sustained regional instability could normalize such adjustments beyond Q2 2026.

This development underscores how localized maritime chokepoint risks now translate rapidly into global pricing mechanisms—especially for China-centric trade lanes. It also highlights growing sensitivity in cross-border e-commerce and light-manufacturing logistics to non-tariff cost variables, where even modest BAF changes affect margin thresholds and competitive quoting.

For stakeholders, the priority is not forecasting escalation—but building responsiveness: reviewing contract terms, stress-testing cost models against ±10% BAF variance, and verifying real-time visibility into surcharge application across service providers.

Conclusion

This BAF adjustment is a measurable, near-term cost impact—not a fundamental shift in trade flow or infrastructure capacity. It serves as a reminder that geopolitical risk in critical maritime corridors continues to exert tangible, quantifiable pressure on logistics pricing from China. Stakeholders should treat it as a prompt to audit contractual flexibility, enhance cost transparency across the supply chain, and prepare for potential repetition—not as evidence of irreversible disruption.
