Re-certify and Stamp
Has your propane tank expired? No problem. At PetroKing Gas we are certified to re-valve your tank for you.
Propane cylinders must be recertified every 10 years. Recertification, sometimes referred to as requalification, includes a visual inspection followed by the replacement of the relief valve and the embedding of a new stamp into the steel collar, which shows the latest inspection date. The cylinder must be empty of propane.
Cylinders cannot be recertified if they have:
- excessive rust
- dented welds
- have broken or damaged collars or foot rings
- have been involved in a fire
Most propane cylinders can be recertified while you wait as it usually only takes about 15 – 20 minutes. If your cylinder has propane in it, we will have to burn it off before we can recertify it and this will take a little longer or if you wish you can pick up your cylinder another day.

Propane cylinders have a range of identifying marks on the cylinder collar. Understanding them assists all propane users.
The manufacture date will show the month and year of manufacture, sometimes separated by an inspector’s symbol. Ten years after the date of manufacture, the cylinder will need to be requalified or replaced.
Example: 04 10 or 04Δ10
How to read this manufacture stamp:
- 04 – Month of manufacture (i.e. April)
- 05 – Year of manufacture (i.e. 2010)
Requalification (Retest) Stamp
As propane cylinders need to be requalified or replaced every ten years, this mark will show when that requalification happened. The easiest way to locate the requalification date on a cylinder is to find a sequence of numbers and letters that end in ‘E’.
Example: 05 PD3 13 E H
How to read this requalification stamp:
- 05 – Month of requalification (i.e. May)
- PD3 – Requalifiers registered mark (this is an identifier that Transport Canada assigns all requalifiers)
- 13 – Year of requalification (i.e. 2013)
- E – Procedure Symbol E (stands for External Visual Inspection) Requalification may occur multiple times over the life of the cylinder, so there may be more than one requalification date stamped on the collar.

Propane cylinders must be inspected and requalified every 10 years – it is against the law to fill an outdated cylinder. The requalification of a cylinder must be done by organizations that have the appropriate equipment, training and certification to do so, and which have been certified by Transport Canada to do the work.
Marks are stamped onto the collar of cylinders identifying the original date of manufacture and any subsequent re-testing dates.
The transportation of propane is regulated under the federal Transportation of Dangerous Goods (TDG) Act and Regulations. Transport Canada administers and enforces the Transportation of Dangerous Goods (TDG) Act & Regulations, which specify requirements for transporting propane, such as means of containment, safety marks, training, permits and emergency response assistance plans.
To get the requirements for your specific situation and jurisdiction, we suggest that you contact Transport Canada.
Propane cylinders must never be thrown in household garbage or recycling containers for roadside pick-up.
For information on how to properly dispose of a propane cylinder in your province, please consult the Canadian Propane Cylinder Disposal Resources list.
The requalification of a propane cylinder must be done by an organization that is registered by Transport Canada to do the work.
Propane prices, like any other commodity, are not set by individual companies. Wholesale prices are determined by market forces; Canada is part of an integrated North American market and many factors affect propane prices, including supply and demand. Propane prices fluctuate like other commodities.
When wholesale prices rise or fall, retailers and distributors generally pass on this change, at least partially, to end-use consumers. And like most consumer products, taxes and delivery charges are added to the wholesale price.
