GST Guide for Bunkering & Marine Fuel Services in Singapore

GST Guide for Bunkering & Marine Fuel Services in Singapore

Navigating the Goods and Services Tax (GST) for the bunkering industry in Singapore requires a precise understanding of when to apply the standard rate (9%) versus zero-rating (0%). Under the Singapore GST Act, specific conditions must be met regarding the delivery of fuel, the type of vessel, and the nature of the services provided.

1. Zero-Rating Bunker Fuel for Foreign-Bound Vessels

You can zero-rate the supply of bunker fuel in Singapore if the fuel is delivered directly on board a foreign-going vessel (a vessel bound for a destination outside Singapore).

Mandatory Documentation for Zero-Rating

To justify the 0% GST rate to IRAS, you must maintain a robust audit trail consisting of:

• Customer Purchase Order: Must specify the vessel name, departure date, and next port of call outside Singapore.

  
  

• Written Delivery Instructions: Directing the fuel to the specific vessel (often included in the PO).

  
  

• Sales Invoice: Issued to your customer.

  
  

• Bunker Delivery Note (BDN): Must be officially endorsed by the vessel’s Master or Chief Engineer.

  
  

• Proof of Payment: Evidence of the transaction from the customer.

  
  

Important Note: If you deliver fuel to a local customer who then resells or delivers it to a foreign-going vessel themselves, you cannot zero-rate the supply. Because you lose custody of the fuel, you cannot guarantee its export; therefore, the supply to the local middleman is standard-rated.

2. GST Treatment for Bunker Tanker Leases

The tax treatment of leasing a bunker tanker depends on the level of control and the inclusion of crew.

A. Lease Without Crew (Bareboat Charter)

When a customer has exclusive use and possession of the vessel without a captain or crew, the supply is a lease of a bunker tanker. This can be zero-rated under Section 21(3)(o) of the GST Act.

B. Lease With Crew (Time/Voyage Charter)

If the tanker includes a captain and crew, the supply is only treated as a "lease" if a written contractual agreement explicitly states so.

• Without a contract: The supply is treated as a "provision of services."

  
  

• Standard-Rated Components: Even if the lease is zero-rated, the following components performed in Singapore are always standard-rated (9%):

  
  

  • Passenger transport, accommodation, and catering.

  • Entertainment and education services.

3. Transport of Fuel and Marine Waste

Under Section 21(3)(l) and Section 21(3)(a)(ii), certain transportation services involving a Qualifying Ship can be zero-rated:

Service Scenario	GST Rate	GST Act Section
Terminal to Ship (Local Anchorage)	0%	21(3)(l)
Tanker to Ship (Local Anchorage)	0%	21(3)(l)
Terminal to Terminal (Local)	0%	21(3)(l)
Marine Waste Removal (to offshore island)	0%	21(3)(l)
Terminal to Ships (Outside Singapore)	0%	21(3)(a)(ii)

What defines a "Qualifying Ship"?

A qualifying ship includes most commercial vessels and oil rigs, but excludes:

1. MPA-licensed passenger harbour crafts or pleasure crafts.

2. Vessels with PUB permits.

3. Vessels designed for recreation/pleasure used within Singapore.

4. GST on Loan of Fuel

In the bunkering industry, suppliers often engage in "mutual fuel loans."

• No Consideration: If the fuel is returned in kind and no payment is exchanged, the lender does not need to account for output tax.

  
  

• Converted to Sale: If the arrangement terminates and the fuel is treated as sold, GST becomes chargeable. The borrower can then claim this as input tax, subject to standard recovery rules.
