Regulations explained
Mobile and stationary fuel tank systems for diesel, heating oil or other fuels are subject to a wide range of legal regulations – depending on their purpose, volume and location. This guide gives you a structured overview of the most important regulations and answers frequently asked questions from everyday practice.
1
Which regulations apply?
Both national and international regulations govern the transport and operation of fuel tank systems and systems handling water-polluting substances. Which ones apply to you depends on the type of transport and intended use.
🇩🇪 National Regulations
GGVSEBDangerous Goods Regulation for Road, Rail and Inland Waterways
AwSVRegulation on Installations for Handling Water-Polluting Substances
GGVSeeDangerous Goods Regulation for Sea Transport
🌍 International Regulations
ADRRoad transport of dangerous goods (Europe)
RIDRail transport of dangerous goods
ADNInland waterway transport
IMDGMaritime transport (IMDG Code)
Basic Principle
Tank systems used for dangerous goods transport must be designed as either an approved packaging or an approved IBC (Intermediate Bulk Container).
2
What does ADR approval mean?
ADR approval confirms that a container has been tested and approved for the transport of dangerous goods. For IBC tank systems, this is indicated by a type plate with the corresponding code.
Features of an ADR-approved tank system
UN marking on the container
Manufacturer identification
Type-approval test details
Regular inspection obligations
Defined maximum fill quantities

⚠ Important
Not every tank system necessarily requires ADR approval as an IBC. Under certain conditions, legal exemptions apply – such as the tradesman's exemption or the 1,000-point rule.
3
Mobile tank systems up to 450 litres & the tradesman's exemption
Simplified rules apply to smaller mobile tank systems. The so-called tradesman's exemption under ADR 1.1.3.1 c) allows the transport of fuels under certain conditions without full application of ADR requirements.
Who may use the tradesman's exemption?
The exemption applies to companies that transport dangerous goods for immediate use, do so in connection with their main business activity, and do not provide commercial transport services for third parties.
Typical use cases in practice
🏗️Diesel for construction machinery on your own job site
🌾Fuel for agricultural machinery
⚡Supplying generators & equipment
🌿Landscaping and grounds maintenance
🏛️Municipal technology & public works depots
🔧Craft businesses with their own vehicle fleet
⚠ Limitations of the tradesman's exemption
The tradesman's exemption does not apply to regular fuel station supply operations, regular intermediate refuelling of multiple job sites under commercial contract, or transport as a primary business activity.
Plastic tanks & the tradesman's exemption
Mobile diesel tanks made of plastic up to 450 litres can fall under the tradesman's exemption. In many cases, a standard ADR approval as an IBC is not required – provided the exemption conditions are met.
Minimum requirements – even under exemption
All containers must be leak-proof, secure for transport, adequately fastened and technically suitable for the fuel. National regulations on handling water-polluting substances must not be violated.
4
The 1,000-point rule (ADR 1.1.3.6)
The 1,000-point rule under ADR Section 1.1.3.6 permits the simplified transport of certain quantities of dangerous goods. Each hazardous substance is assigned to a transport category with a corresponding multiplier (factor).

Obligations even under simplified transport
1
Load securingContainers must be secured against shifting, tipping and damage.
2
Appropriate markingLimited quantities must be labelled accordingly (diamond or LQ mark depending on quantity).
3
Fire extinguisher in the vehicleAt least 2 kg dry powder or equivalent extinguisher must be carried.
4
Employee trainingAll persons involved must be instructed on hazards and required measures.
5
Inspection obligations for ADR IBC tank systems
ADR-approved IBC tank systems are subject to legally prescribed recurring inspections. The inspection intervals and scope are defined as mandatory in the ADR.
Inspection after 2.5 years
Visual inspection of external condition
Check of marking and labelling
Inspection of fittings (valves, connections)
Verification of fastening and structural integrity
Inspection after 5 years
All items from the 2.5-year inspection
Leakage test
Internal inspection (where possible)
Pressure test of the container
Renewal of the inspection certificate
Note on simple packaging
For mobile tank systems not classified as IBCs (e.g. UN-tested packaging up to 450 L), simplified inspection rules may apply. If in doubt, always consult the manufacturer's specifications and the current ADR edition.
6
Stationary use of mobile tank systems
If a originally mobile tank system is operated permanently at a fixed location, it may legally be classified as a stationary installation – with far-reaching consequences.
⚠ Important threshold: 6 months on-site
If a mobile tank system is operated at the same location for more than 6 months, the additional requirements of the AwSV (Regulation on Installations for Handling Water-Polluting Substances) apply.
Additional requirements for stationary operation
🛡️
Containment bund
A suitable containment device for the full volume of the installation is required.
🔧
Certified contractor requirement
Installation, maintenance and inspection must be carried out by a certified specialist company in accordance with § 62 AwSV.
📋
Inspection obligations (AwSV)
Regular inspections by approved expert organisations (SVO) depending on water hazard class and volume.
📍
Installation site requirements
Safety distances to water bodies, sewage systems and drainage pipes must be observed.

Frequently asked questions (FAQ)
Not necessarily. If you are transporting diesel for your own business use (e.g. construction machinery, agriculture), the tradesman's exemption under ADR 1.1.3.1 c) will often apply. However, the tank must be leak-proof, securely fastened and technically suitable. An explicit UN or ADR approval is not strictly required in this case – but is always recommended.
Under the 1,000-point rule (ADR 1.1.3.6), up to 1,000 litres of diesel may be transported under simplified conditions (transport category 3, factor 1). Many ADR obligations are waived, but load securing, marking, a fire extinguisher and employee training remain mandatory.
Once the installation has been in place at a fixed location for more than 6 months, it is treated legally as a stationary installation. The requirements of the AwSV then apply: containment bund, certified contractor obligation, possible inspection by an approved expert organisation and compliance with safety distances.
Yes, mobile diesel tanks made of plastic up to 450 litres can fall under the tradesman's exemption and are widely used in many industries (construction, landscaping, agriculture). The key factors are the intended use, the volume transported, the secure construction and use for one's own purposes. A UN-tested version is recommended.
ADR-approved IBC tank systems must be inspected after 2.5 years and again after 5 years. The 5-year inspection includes a more comprehensive leakage and pressure test. The inspection must be carried out and documented by a recognised body.
The tradesman's exemption is not restricted to a specific fuel, but petrol is subject to stricter regulations (transport category 2, factor 3). Petrol is classified as more flammable and more hazardous than diesel. We recommend particular care and, if in doubt, consultation with the relevant authority.
The ADR is reissued every two years. The current edition can be found on the website of the Federal Ministry for Digital and Transport (BMDV) and at UNECE. Always make sure you are using the currently valid version, as regulations are updated regularly.
