Hormuz Strait Disruption Drives Global BAF Increases, Pressuring China's Export Logistics Costs
BAF increases hit China's exporters amid Hormuz Strait disruption—learn how ZTO, YTO & J&T surcharges impact FOB/CIF costs, SME margins & global logistics planning.

Time : Apr 26, 2026

Amid ongoing U.S.-Israel-Iran tensions, maritime passage through the Strait of Hormuz remains constrained, prompting major Chinese cross-border logistics providers—including ZTO, YTO, and J&T Express—to announce fuel surcharge (BAF) adjustments effective April 25. This development directly affects export freight settlement, FOB/CIF quotation structures, and delivery schedule stability for Chinese foreign trade enterprises—particularly SMEs with time-sensitive orders and those serving long-haul routes to Southeast Asia, the Middle East, and Latin America.

Event Overview

As confirmed by public announcements from ZTO, YTO, and J&T Express on April 25, these leading express and cross-border logistics service providers have introduced or increased their fuel surcharge (BAF) in response to sustained shipping restrictions in the Strait of Hormuz. The situation stems from ongoing regional military tensions involving the U.S., Israel, and Iran. Brent crude oil prices have risen above USD 98 per barrel, reflecting heightened energy market volatility. No official change in international maritime safety advisories or port authority directives has been reported beyond these commercial BAF adjustments.

Industries Affected

Direct Exporting Enterprises

These companies face immediate pressure on freight cost predictability. Since BAF is typically applied as a percentage or flat fee atop base ocean/air rates—and often recalculated monthly—it introduces variability into final invoice amounts under FOB or CIF terms. For SMEs quoting fixed-price contracts, unanticipated BAF hikes may erode margins unless contract clauses explicitly allow for fuel-related adjustments.

Manufacturing Exporters with Just-in-Time Delivery Requirements

Producers relying on tight production-to-shipment windows—especially in electronics, automotive components, and fast-moving consumer goods—are exposed to both cost and scheduling risk. Delays caused by rerouted vessels or port congestion near the Gulf may compound BAF-driven cost increases, affecting on-time delivery KPIs and customer trust.

Cross-Border E-commerce Sellers

Vendors shipping via integrated express-logistics channels (e.g., door-to-door parcels to Middle Eastern or Latin American end consumers) absorb BAF as part of total landed cost. With limited pricing power in competitive online marketplaces, such sellers may struggle to pass through full surcharges—potentially compressing profitability per order, particularly for low-value, high-volume SKUs.

Third-Party Logistics (3PL) and Freight Forwarding Providers

These intermediaries bear dual exposure: upward pressure on carrier-sourced rates and downward pressure from clients unwilling or unable to accept frequent surcharge revisions. Their ability to maintain margin stability depends heavily on transparency in cost-pass-through mechanisms and contractual flexibility regarding fuel adjustment triggers.

What Relevant Businesses and Practitioners Should Monitor and Do

Track Official Maritime Safety Advisories and Carrier-Specific BAF Policies

While ZTO, YTO, and J&T have announced adjustments as of April 25, other carriers—including Maersk, MSC, and COSCO—have not yet issued public BAF updates tied to Hormuz. Businesses should monitor weekly bulletins from the UK Maritime Trade Operations (UKMTO), the U.S. Fifth Fleet, and individual liner operators for changes in routing guidance or formalized surcharge frameworks.

Review Contract Language for Fuel Adjustment Clauses—Especially in FOB and CIF Agreements

Exporters using standard INCOTERMS® 2020 must verify whether their sales contracts define how fuel surcharges are allocated between buyer and seller. Under FOB, the buyer bears main carriage costs—and thus any BAF levied by the carrier—but only if the clause explicitly permits such add-ons. Under CIF, the seller retains responsibility for freight and insurance; unanticipated BAF increases may require renegotiation or contingency budgeting.

Assess Exposure by Route and Product Category

BAF impact is not uniform. Routes passing through the Persian Gulf (e.g., Shanghai–Dubai, Ningbo–Jeddah, Shenzhen–Santos) face higher likelihood of surcharge application than trans-Pacific or intra-Asia lanes. Similarly, air cargo shipments—though less dependent on Hormuz—may see secondary BAF effects due to jet fuel price linkage. Companies should map current export lanes against known chokepoints and flag high-exposure categories for scenario planning.

Prepare Operational Contingencies for Quotation and Procurement Cycles

Given the volatility, businesses should consider shortening quotation validity periods (e.g., from 30 to 14 days), building BAF buffers into internal cost models, and aligning procurement lead times with expected freight rate review cycles. For forwarders and exporters, maintaining updated BAF reference tables from key carriers—and sharing them transparently with procurement and sales teams—is a practical step toward internal alignment.

Editorial Perspective / Industry Observation

From an industry perspective, this BAF adjustment wave is better understood as an early-stage operational signal—not yet a systemic cost shock. While Brent crude’s move above USD 98 signals energy market stress, current BAF implementations remain carrier-specific, discretionary, and non-regulated. Analysis来看, the April 25 announcements reflect proactive risk mitigation rather than broad-based tariff enforcement. Observation来看, the absence of coordinated global liner alliance action (e.g., via the Ocean Carrier Equipment Management Association or similar bodies) suggests localized commercial response—not structural freight market re-pricing. Current更值得关注的是 whether subsequent weeks bring broader adoption across deep-sea container lines or air cargo integrators, which would indicate escalation beyond express parcel logistics.

Conclusion

This development underscores how geopolitical friction at maritime chokepoints translates rapidly into tangible cost and planning variables for China’s export supply chain. It does not represent a new trade barrier or regulatory intervention—but rather a reminder that fuel surcharges remain a flexible, commercially driven lever for logistics providers amid uncertainty. For stakeholders, the appropriate stance is calibrated vigilance: treat the current BAF adjustments as a data point—not a turning point—while preparing for possible expansion across transport modes and service tiers.
