Bunker Adjustment Factor (BAF) Definition

The Bunker Adjustment Factor (BAF) refers to a high-cost expense, payment, or surcharge to individuals shipping on ocean vessels. This is an additional charge to the base rate of ocean freight. This additional charge reflects the costs of fuel otherwise known as bunker oil. The bunker adjustment factor reflects the adjustment price of fuel (bunker oil) which is often done on a quarterly basis.

The Bunker adjustment factor is not the same as the dase fright rate, it is an additional charge. Voyage on ocean vessels by individuals often attract BAF and this is subject to fluctuations.

A Little More on Bunker Adjustment Factor in Shipping on Vessels

Bunker oil, otherwise called fuel is the most critical cost of shipping on ocean vessels. It is often higher than the carrier costs, sometimes, it might rise up to 50% of the cost. Bunker oil cannot be separated from the shipping industry, it is the power source for the engine of vessels. As a result of increase in the use of shipping, the use of bunker oil is essential. In some cases, carriers incur more bunker cost than that base freight rate. Bunker oil is crude and polluting, also, before it can be used in the vessels’ engine, it must be heated. The cost of storing and transporting this oil among other factors are responsible for the expensive nature of bunker oil.

The increased costs resulting from fluctuation of the price of bunker fuel for vessels gave rise to the development of Bunker Adjustment Factor. This is high cost surcharge to individual shipments which differ from the base freight rate.

However, the fact that bunker oil is crude does not mean that there is a correlation between its prices and prices of crude oil. That is, fluctuations or changes in oil prices do not affect the price of bunker oil, they are not directly related. The way bunker oil is made useful for engine vessel (refined), its storage and transportation is quite different from other oils.

In the shipping industry, the bunker adjustment factor determines the high cost surcharge that carriers add to the base freight rates. This is additional expenses that cover the expense of bunker oil (fuel used by engine vessel). BAF is an effective way of accurately calculating annual and quarterly costs related to freight.
