EBS, or Emergency Bunker Surcharge, is an additional ocean freight charge applied by carriers when marine fuel costs rise suddenly or become difficult to absorb within standard freight rates. Bunker fuel is the fuel used by ships, so the surcharge helps carriers recover unexpected increases in vessel operating costs. EBS may be applied by trade lane, container type, shipment, or carrier tariff and can change quickly depending on fuel markets and carrier pricing policies.
An Emergency Bunker Surcharge (EBS) is an additional fuel surcharge imposed by ocean carriers when bunker fuel prices spike sharply between regular BAF adjustment cycles. It is applied per container on top of the base rate and existing BAF.
- Imposed quickly in response to sudden fuel cost increases
- Applied on specific trade lanes where the carrier determines it is necessary
- Rate and duration vary by carrier and lane
Monitor carrier surcharge announcements on your regular trade lanes to incorporate EBS into landed cost projections.
