Why Your April Invoices Have Four New Fuel Lines — and What Each One Is Actually Pricing

If you handle pricing or procurement, your April invoices probably read like a reading comprehension test. Bunker Adjustment Factor reset on one lane. An “Emergency Fuel Surcharge” added to another. A separate “Emergency Operations Charge” with a similar name but a different code, applied to feeder legs only. An inland fuel surcharge ticked up. And somewhere in your contract review notes, the question: are these the same shock surfacing in different places, or are some of them already double-pricing fuel that another line is supposed to cover?

The shock is one. The cost lines are many. This post traces how a single upstream energy disruption — the near-shutdown of the Strait of Hormuz — transmits through to six discrete charges that show up in different places on a shipper’s cost stack. The map matters because some of these charges price the same fuel exposure twice, and at least one of them is an upstream structural shift that none of the surcharges price at all.

The upstream event: Hormuz traffic near a standstill

Pre-war daily transit average: roughly 125–140 vessels. By late April 2026, large commercial transits had fallen to single digits on some days. Bloomberg’s vessel-tracking data showed eight crossings on April 26 — four inbound, four outbound — with most of the traffic coming from a small set of Iran-linked ships still moving under the dual blockade. Panama Canal officials have also tied the surge in reservation demand and auction pricing to the Middle East conflict, with reporting linking the traffic shift to the effective closure of Hormuz and avoidance of Red Sea risk.

This is the upstream event. Roughly a quarter of seaborne oil trade and about one-fifth of global LNG trade normally move through the strait. When that flow is interrupted at the volume it has been, the price-discovery mechanism is bunker fuel — and bunker prices are where the transmission begins.

Step 1 — Bunker prices reset higher

The first place the disruption shows up is in bunker port pricing. Reporting from ENGINE (republished by Hellenic Shipping News) showed LSMGO at the Port of Kingston rising from around $860/mt in late February to above $1,400/mt — a 60%+ jump driven largely by Hormuz-linked supply pressure. VLSFO at Freeport moved from roughly $690/mt to near $890/mt over the same window. By late April, Brent was again trading above $100/bbl as U.S.–Iran peace talks stalled.

This is the only step that’s a true price signal. Everything that follows is a carrier or operator response to this signal — and the responses don’t all live in the same place on your invoice.

Step 2 — BAF / EFS on carrier-operated vessels

Standard Bunker Adjustment Factors, which most carriers reset quarterly or monthly, absorb part of this. But Q2 BAFs were calibrated against bunker prices from before the late-March escalation. So most carriers have layered a separate Emergency Fuel Surcharge (EFS) on top.

Hapag-Lloyd’s EFS, effective March 23, charges $160/TEU for dry containers on long-haul front-haul routes (and $225/TEU for reefers), and $70–100/TEU on long-haul back-haul and intra-regional trades. The carrier was explicit that the EFS covers “extraordinary costs not addressed by its existing marine fuel recovery charge” — i.e., this is layered, not a substitute. Other carriers have used different mechanics (resetting BAF off-cycle, applying a “war risk fuel adjustment,” raising base rates) but the pricing logic is the same: the standing fuel mechanism didn’t anticipate Hormuz.

Where this lands on your invoice: a fuel-coded surcharge line on the main ocean leg, distinct from BAF, applicable to vessels the carrier itself operates.

Step 3 — EOO/EOD on third-party feeders

This is the step most shippers are not parsing correctly. Carriers operate their own mainline vessels, but most feeder legs — moving cargo between a hub port and a regional spoke — are run by third-party feeder operators on contracted slots. When bunker prices spike, those operators raise their slot rates to the line carriers. The carriers then pass that through as a separate charge.

Hapag-Lloyd has now filed three rounds of Emergency Operations Charges (EOO/EOD):

Caribbean and South America — effective April 21 (non-FMC) — $50–150/TEU
Middle East — effective May 1 (non-FMC) / May 24 (FMC) — $35/TEU
South Europe, North Africa, Black Sea, Eastern Med — effective May 8 (non-FMC) / May 27 (FMC) — mostly $50/TEU, with Lisbon, Bilbao, and Gijón at $60/TEU and Las Palmas, Santa Cruz de Tenerife, and Rades lower

The carrier’s own framing is unusually clear on the layering: EFS covers fuel for vessels Hapag-Lloyd operates; EOO/EOD covers additional charges levied by third-party feeder providers. They are designed to stack, not substitute. A shipment moving from a U.S. inland origin to an Eastern Mediterranean destination via a Med hub could see EFS on the mainline and EOD at the destination feeder leg — both fuel-driven, both new, both layered on top of BAF.

Where this lands on your invoice: a separate charge code, applied at origin or destination depending on which leg uses third-party feeders. If your carrier’s network is feeder-heavy on a given lane, this can be the larger of the two fuel surcharges. Other carriers are moving in the same direction — the Journal of Commerce reports that varied carrier strategies on bunker volatility have delayed completion of some 2026–27 service contract negotiations heading into May 1.

Step 4 — Inland fuel surcharges

Diesel transmits the same shock to inland legs. Hapag-Lloyd renamed and updated its North Europe inland fuel surcharge — EFO/EFD (Emergency Fuel Origin / Emergency Fuel Destination), formerly FOI/FDI — for “global alignment,” citing diesel volatility tied to international energy markets. Most major carriers had already reset their inland fuel surcharges in March or early April; we covered the full carrier-by-carrier table in Every Major Carrier’s Inland Fuel Surcharge, April 2026 Edition.

Where this lands on your invoice: a per-mile or percentage adjustment on the inland portion of door-to-door moves, often invoiced as a separate line by the inland carrier or rolled into the carrier’s all-in inland rate. The same fuel pressure that pushed up bunker prices at Kingston is pushing up diesel at U.S. truck stops — different fuel, same upstream cause.

Step 5 — Panama Canal slot premiums

Hormuz disruption pushes vessels onto alternative routes. The most consequential alternative for U.S. and Asia-bound flows is the Panama Canal — and the Canal is now publicly pricing the surge.

The Panama Canal Authority confirmed in late April that average auction prices had risen to roughly $385,000, up from about $135,000–$140,000 before the latest demand surge. The ACP also confirmed that some vessels have paid more than $1 million in recent auctions. According to Argus data cited in the same briefing, the top auction print this month was $1.7 million for a Panamax slot and $4 million for a Neopanamax slot. The ACP attributed the surge to the conflict-driven rerouting environment: the Iranian war, the effective closure of the Strait of Hormuz, and shipping avoiding the Red Sea.

Auction slots are a small fraction of total transits — three to five per day, against roughly 37 daily transits — so this isn’t a base-toll story for most cargo. But it does tell shippers two operational things. First, Panama is now one of the relief valves for Hormuz and Red Sea diversions, which means container transit times via Panama may be less predictable than the published schedule suggests. Reported canal wait times have risen from under a day to about 4.8 days northbound and 3.8 days southbound. Second, vessel operators paying $1M+ for an auction slot are absorbing a cost that, on the next contract round, the cargo side is likely to see priced into base ocean rates.

Where this lands on your invoice: not directly today, for most cargo. But it shows up indirectly as schedule volatility on Panama-routed services, and it’s a leading indicator for base-rate movement on Asia–US East Coast and Europe–West Coast lanes.

Step 6 — Equipment repositioning costs

The least-visible step is also the one with the longest tail. With Hormuz traffic near a standstill, the equipment loop that normally has containers cycling India/Middle East → Europe and back has broken. We mapped the import/export imbalance in 3.3 Containers In, 1 Container Out earlier this month. The cost transmission from broken repositioning is slower but real: empty repositioning surcharges, equipment imbalance surcharges, and (more often) the absence of equipment at origin, which forces shippers onto more expensive lanes or later sailings.

Where this lands on your invoice: not always as a separate line. Often as a higher base rate at booking, or as an inability to book at the rate the contract specified. Compare your booked rate against the contract rate over the next 60 days — that delta is partly equipment-driven, partly fuel-driven, and the carrier won’t usually tell you which.

The structural shift the surcharges don’t price

On April 28, the UAE announced it will withdraw from OPEC and OPEC+ effective May 1, ending nearly six decades of membership. The UAE was one of OPEC’s largest producers, with production around 3.4 million bbl/day before the current conflict and capacity near 5 million bbl/day. UAE Energy Minister Suhail al-Mazrouei told CNBC the timing was deliberately chosen to “have a minimum impact on the price.”

Two things to watch from this. First, some analysts expect the UAE exit to add medium-term downward pressure once Hormuz shipping normalizes, because it gives the UAE more freedom to raise output outside OPEC+ quota discipline. That would eventually relieve the bunker-price pressure that’s driving Steps 1–4 above. Second — and more important for shippers planning Q3 — the OPEC+ coordination mechanism is weaker than it was on April 27. If other Gulf producers follow the UAE out, the predictability of supply-side response to demand changes will fall, which means the bunker-price volatility that just generated four new surcharge lines could become more frequent rather than a one-off.

If your team is currently reconciling fuel-coded surcharges across carriers and trying to figure out which ones are layered, which are double-priced, and which lanes are most exposed, a 30-minute walkthrough of how operations teams set up automated surcharge tracking and lane-level exception alerts may save the spreadsheet work.

What an operator can do this week

Three concrete moves while the cascade is still resolving:

Audit the layering, not just the totals. Pull every fuel-coded line from your last 60 days of carrier invoices. Tag each one as: BAF (standing), EFS or equivalent (vessel emergency), EOO/EOD or equivalent (third-party feeder), inland fuel surcharge, or other. Most shippers find at least one lane where two of these are overlapping in scope — that’s a renegotiation conversation, not a payment dispute, and the conversation is much sharper when you can name the specific charges.

Pressure-test feeder exposure on Med, Caribbean, and Middle East lanes. If you ship via a hub-and-feeder structure to any port in those regions, the EOO/EOD layer is now structural. Ask your carrier rep for the specific feeder leg and the per-TEU charge before May 8 (Med) and May 27 (FMC trades).

Watch Panama auction prints as a leading indicator. If average auction prices stay around the late-April level through May, that’s a signal that base rates on Panama-routed services may move on the next quarterly reset. If they fall sharply — which would happen if Hormuz reopens or the UAE’s exit produces meaningful supply relief — the BAF line on your next invoice should eventually reflect it, depending on the carrier’s fuel-adjustment cycle.
