Sulphur in Diesel Fuel Regulations
Maximum Sulphur Limits for Diesel Fuel
The Sulphur in Diesel Fuel Regulations set maximum limits for sulphur in diesel fuel for use on-road, off-road, in rail (locomotive), vessels, and stationary engines. The current maximum sulphur limits and effective dates for production, import and sales of diesel fuel in Canada are summarized in the table below.
|Diesel fuel for use in:||Regulated Activity||Sulphur Limit (mg/kg)||Effective Date|
|Large Vessels (Marine Diesel)||Production, import or sales||1000||June 1, 2014|
|Large Stationary Engines||Production, import or sales||1000||June 1, 2014|
|Non-large Vessels||Production or import||15||June 1, 2012|
|Non-large Vessels||Sales||15||June 1, 2014|
|Small Stationary Engines||Production, import or sales||15||June 1, 2014|
|Rail (locomotive)||Production or import||15||June 1, 2012|
|Rail (locomotive)||Sales||500||October 1, 2007|
|Off-road Engines||Production, import or sales||15||Since 2010|
|On-road Vehicles||Production, import or sales||15||Since 2006|
The goal of the Sulphur in Diesel Fuel Regulations is to ensure that the level of sulphur in diesel fuel used in Canada will not impede the effective operation of advanced emission control technologies installed on vehicles and engines.

12-hour Advance Notification of Imports
The Regulations require that importers intending to import at any one time more than 100 m3 of diesel fuel or more than 1 000 m3 into a province in one day, notify Environment Canada at least 12 hours in advance of imports.
Schedule 1 - Annual Report of Sulphur Concentration in Diesel Fuel
The Annual Report of Sulphur Concentration in Diesel Fuel (Schedule 1) must be submitted separately for each facility at which a person produces diesel fuel and for each province or territory into which a person imports diesel fuel. This report is required to be submitted 45 days after the end of the calendar year, on February 14th.
Schedule 2 - Registration Report
A Registration Report (Schedule 2) must be submitted no later than 5 days before the day on which a person produces or imports diesel fuel for the first time. The person must notify Environment Canada in writing of any changes in the information that was provided in Schedule 2, no more than five days after the change. If typical annual volume changes, no update is required.
For the purpose of determining compliance with the concentration requirements, the Regulations specify the ASTM International method ASTM D5453-09, Standard Test Method for Determination of Total Sulfur in Light Hydrocarbons, Spark Ignition Engine Fuel, Diesel Engine Fuel, and Engine Oils by Ultraviolet Fluorescence as the reference test method for measuring sulphur. (The test method is available from ASTM International. Note that this link leads to a site belonging to an entity not subject to the Official Languages Act. Information on this site is available in English only.)
The Regulations include provisions for equivalent methods to be used for reporting purposes. A producer or importer of diesel fuel proposing to use an equivalent test method for reporting purposes must provide to Environment Canada at least 60 days before using the method a description of the method and evidence that it is equivalent. Please refer to the Regulations for specific requirements.
Equivalency for reporting purposes has been demonstrated in accordance with the Regulations for the following methods:
- ASTM D-7039: Standard Test Method for Sulfur in Gasoline and Diesel Fuel by Monochromatic Wavelength Dispersive X-ray Fluorescence Spectrometry - for sulphur concentrations in diesel fuel in the range of 2 to 500 mg/kg
- ASTM D-2622-98: Standard Test Method for Sulfur in Petroleum Products by Wavelength Dispersive X-Ray Fluorescence
- CAN/CGSB-3.0 No. 16.0-95: Standard Test Method for Sulfur in Diesel Fuel by Energy Dispersive X-Ray Fluorescence Spectrometry (EDXRF) - for sulphur concentrations in diesel fuel greater than 500 mg/kg.
- ASTM D7220: Standard Test Method for Sulfur in Automotive, Heating, and Jet Fuels by Monochromatic Energy Dispersive X-ray Fluorescence Spectrometry – for sulphur concentrations in diesel fuel in the range of 6 to 50 mg/kg
New requests to use equivalent methods must be demonstrated using ASTM International standard ASTM D6708-08, Standard Practice for Statistical Assessment and Improvement of Expected Agreement Between Two Test Methods that Purport to Measure the Same Property of a Material. (The test method is available from ASTM International. Note that this link leads to a site belonging to an entity not subject to the Official Languages Act.
