Department of Energy Business — Fuel Standards and Station Safety
The Ministry of Energy department that decides how good the fuel in your tank must be, and what safety rules the station pumping it has to meet.

What you can do
-
Regulator of the downstream fuel trade
Covers the chain from the refinery gate or the import terminal all the way to the pump nozzle and the cooking-gas cylinder in a kitchen.
-
Sets the specification for every fuel grade
Issues the announcements that define petrol, gasohol, high-speed diesel, fuel oil and LPG — binding on every trader.
-
Licenses stations, depots and storage sites
Anyone storing or selling fuel above the legal thresholds must notify the authority or hold a licence before opening.
-
Writes the storage and transport safety rules
Safety distances, tanks, vapour venting, firefighting equipment, and the periodic testing of cylinders and tanker vehicles.
-
Takes complaints about off-spec fuel
Samples fuel from stations for laboratory testing and acts against traders selling product that fails the specification.
-
Tracks fuel volumes and legal reserves
Collects production, import, export and sales data, and holds large traders to the statutory stockholding obligation.
What the Department of Energy Business does
The Department of Energy Business — DOEB — sits under the Ministry of Energy and regulates the downstream end of the fuel trade: from the moment petrol or gas leaves a refinery or clears an import terminal, through to the nozzle a driver holds and the cylinder standing beside a kitchen stove. It works through two instruments. The first is the set of announcements defining the characteristics and quality of each fuel — the chemistry a product must meet to be sold legally. The second is licensing and site inspection, which governs who may store fuel, how much, in what manner and with which safety measures. The two are linked: off-spec fuel and an unsafe forecourt end up harming the same people.
Who ends up dealing with it
- Anyone opening a petrol or gas station — the licensing process begins at the land-selection and design stage, well before the first pile goes in.
- Fuel traders and importers, who must register in the trading class the law assigns them and report their volumes to the department at regular intervals.
- Depot owners, operators of bulk storage sites, and those moving fuel by tanker or by pipeline.
- LPG businesses — filling plants, retail outlets, and the cylinder testers and inspectors who work for them.
- Factories, farms and construction sites keeping fuel for their own use — many of whom do not realise the quantity on site already triggers a duty to notify or to hold a licence.
- Drivers who want to report a station they suspect of selling fuel that does not meet the standard.
The three control categories, and how they differ
The fuel-control law does not treat everyone alike. It sorts operations into three categories by the type and volume of fuel held or sold, and the legal burden rises with the volume and the risk. The thresholds themselves live in ministerial regulations and are revised from time to time, so check the current figures before relying on them.
| Category | Roughly what it covers | What you must do first |
|---|---|---|
| Category 1 | Small quantities, lower risk | No notification or licence, but the prescribed safety rules still bind you |
| Category 2 | Mid-range volumes — above category 1, below the licence threshold | Notify the licensing authority before you start |
| Category 3 | Large operations: service stations, depots, gas-filling plants | Hold a licence before building and before opening, and accept periodic inspection |
Fuel quality at the pump, and how complaints work
The quality announcements are documents almost no motorist ever opens, yet they touch everyone who fills a tank. They fix the acceptable values for each grade — octane, the ethanol or biodiesel share, and the sulphur content that feeds directly into air pollution and fine particulate matter. Tightening the sulphur limit is a real environmental lever, not merely a refinery technicality. For the values in force today, read the most recent announcement on the official site.
Storage and transport safety, and the national reserve
The other half of the department’s work is invisible from the forecourt. The safety rules reach from the distance between a tank and the building next door, through tank types and installation, vapour venting and firefighting equipment, to the periodic testing of cylinders and tanker vehicles. Alongside that sits security of supply: large traders must hold reserve stock at the rate the law prescribes and report their production, imports, exports and sales, so the country can see how much fuel is actually in the system. That rate is a policy setting and can change, so never quote a figure from anywhere but an official announcement.
Why this page has to exist
The department’s website shuts search engines out of the entire site. Its fuel-quality announcements, licence procedures and safety criteria — material it publishes deliberately — therefore never surface in search results at all. The people this actually hurts are the landowner weighing up a filling station, the factory manager unsure whether the tank in the yard needs to be notified, and the driver whose car started misbehaving an hour after a fill-up. Each of them types a question into Google in Thai and gets back an old forum thread, an advert from a licence fixer, or an article copied from another article, rather than a page written by the body that made the rules.
So this page stands in as the signpost that can be found: it explains the department’s remit in the words people actually use, separates what belongs to it from what belongs elsewhere, and hands you on to the official site for the current text. ThaiGov.co is an independent directory with no affiliation to the department. We take no applications, no complaints and no fees.
How to use it
-
Work out which kind of matter you have
The department’s work falls into three broad groups: licensing and notification, fuel quality standards, and the safety of premises and equipment. Knowing which group your matter belongs to shortens the search for the right contact considerably.
-
Check which control category your operation falls into
The fuel-control law sorts operations into three categories according to the type and volume of fuel stored or sold. The obligations range from none at all to a licence that must be in hand before construction starts.
-
Identify who your licensing authority actually is
It is not always the department itself. In many cases the power to license sits with the local administrative authority where the site is located, so asking there before you file anything can save weeks.
-
Assemble the drawings and technical paperwork
An application for a station, depot or gas-filling site needs a site layout, construction drawings and calculations certified by a licensed engineer, together with proof of land rights and company documents.
-
File, receive the inspection, then plan for renewal
Your papers are reviewed and the site inspected before a licence is issued. Once you are trading the duties continue: renewals, notifying material changes, and periodic testing of tanks and equipment.

Frequently asked questions
What does the department cover — and what does it not?
It covers fuel quality, the licensing and safety of premises that store or sell fuel, and volume and reserve data. It does not set pump prices — price structure and the oil fund sit with other bodies inside the Ministry of Energy. A question about pricing or margins is a different matter entirely.
I want to open a petrol station — where do I start?
A service station is normally a controlled operation that must be licensed before construction begins, not after. Start by checking the town-planning zoning for the plot, then approach the licensing authority for that area — often the local administration — for the current list of required documents and drawings.
I suspect a station is selling bad fuel. Who do I tell?
Fuel quality is squarely the department’s job. Report it through the official complaint channel on its website, giving the station’s name and location, the date and time you filled up, the grade, and the pump number if you noted it. The more precise the details, the better targeted the sampling visit.
The pump seems to be short-measuring. Same department?
No — the accuracy of the dispenser is a weights-and-measures matter, handled by the Department of Internal Trade under the Ministry of Commerce. The Department of Energy Business looks after what is in the fuel, not how much of it came out. Bad product goes to one; short measure goes to the other.
My car started running badly right after filling up. What now?
Preserve the evidence first: the receipt, a photo of the pump, and the exact date and time. Do not drain the tank yet — the fuel still in it is the sample that can be tested. Then notify the station in writing and file with the department in parallel. If other drivers hit the same trouble on the same day, say so; it points at the station’s storage rather than at your car.
Do LPG shops and stations need a licence too?
Yes. LPG stations, filling plants and retail shops holding more than the prescribed quantity are all controlled operations. Beyond the licence there are rules on safety distances, how cylinders are arranged, and periodic cylinder testing. A small shop holding little gas may sit in a lighter tier, but the safety requirements still apply.
How do I know an announcement or a caller is genuinely from the department?
Genuine announcements are published on the department’s site under the doeb.go.th domain, and instruments in force also appear in the Royal Gazette. Be wary of anyone offering to “guarantee” a licence for a cash fee or a transfer to a personal account. Official fees are set by law and always come with a receipt — if in doubt, check with the local licensing authority before paying anything.
