It starts with the vessel's status
The single most important concept in Indian bunkering is whether the vessel qualifies as a "foreign-going vessel" under Section 2(21) of the Customs Act, 1962. That status determines how the supply is treated for duty and tax. A vessel engaged on a foreign run qualifies; a vessel on a purely coastal run generally does not. Establishing and documenting that status correctly is the foundation of a clean delivery.
Duty and tax treatment
Indian law treats fuel taken on board a foreign-going vessel as ship's stores. Under the stores provisions of the Customs Act (Sections 88 and 89), goods supplied as stores to a foreign-going vessel are treated as export goods and may be supplied free of duty, and imported bunker fuels benefit from a customs-duty exemption. The GST position has attracted differing rulings over the years, but the prevailing line of authority — reinforced by recent tribunal decisions — treats bunker fuel supplied to a foreign-going vessel as an export, even where the vessel is berthed in Indian waters. The practical point is that treatment hinges on the vessel's foreign-going status, and it should be confirmed for each stem rather than assumed.
Nomination and lead time
A stem begins with a nomination specifying the vessel, port, grade or grades, quantity, ETA and any particular requirements — maximum viscosity, ISO 8217 edition, specific delivery mode. Standard grades at the larger ports need modest lead time; specialty requirements and smaller ports need more. Building in extra lead time protects against barge scheduling and weather windows, which matter on the open anchorages of the Indian coast.
Customs and port formalities
A compliant delivery is coordinated across three parties: customs, for the stores and shipment documentation that supports the duty-free treatment; the port authority, for clearances and access; and the barge or terminal operator, for scheduling. Aligning these in advance is what keeps a delivery on time.
Documentation that matters
The core records are the Bunker Delivery Note (product, quantity in mass, density, flash point, sulphur content), the sealed MARPOL representative sample drawn at the manifold, the customs stores documentation, and the commercial paperwork. These are also the evidentiary basis for any later dispute, so they must be right at the time of delivery.
Getting it right
Indian bunkering rewards preparation: confirm the vessel's foreign-going status, settle the documentation framework before the barge arrives, and follow the same delivery discipline — joint gauging, manifold sampling, a properly completed BDN — that applies anywhere. Done that way, it is as clean as any established hub.
Frequently Asked Questions
Does a foreign-going vessel pay Indian tax on bunkers?
Fuel supplied as stores to a foreign-going vessel is treated as duty-free under the Customs Act, and the prevailing position treats it as an export for GST purposes. The treatment depends on the vessel qualifying as foreign-going, so it should be confirmed per stem.
What makes a vessel 'foreign-going'?
Section 2(21) of the Customs Act defines a foreign-going vessel broadly as one engaged in the carriage of goods or passengers between an Indian port and a port outside India. A vessel on a purely coastal run generally does not qualify.
How much lead time does an Indian stem need?
Standard grades at the major ports need only modest notice, while specialty fuels, smaller ports and weather-exposed anchorages call for more. Allowing extra time protects against barge scheduling and sea-state delays.
Do I need a surveyor for an Indian delivery?
It is not mandatory, but an independent quantity survey and disciplined manifold sampling are sound practice on any sizeable stem, in India as elsewhere.
