Dangerous goods stickers: classes, obligations and audit evidence in shipping

The obligation to affix dangerous goods stickers arises from the European Agreement on the International Transport of Dangerous Goods by Road (ADR), transposed into German law by the Dangerous Goods Ordinance on Roads, Railways and Inland Waterways (GGVSEB) and supplemented by the Dangerous Goods Officer Ordinance (GbV). According to Section 9 GGVSEB, anyone who ships, loads, transports or receives dangerous goods is jointly responsible for the correct labelling. Missing or incorrect dangerous goods stickers are not only a safety problem, but also a separate offense under the GGBefG, with fines of up to 50,000 euros per violation. In addition, there is a risk of civil claims for damages if incorrect labelling leads to accidents or environmental damage.

This article organises the ADR labelling according to daily shipping practice. It explains the nine classes of dangerous goods, the obligation to have a UN number and package labelling, the obligations of those involved and the documentation requirements. CIVAC operates a German compliance platform and officer-as-a-service. Licence the workspace for your internal representatives, or have our representatives order it. According to the GbV, the dangerous goods representative is mandatory in almost every shipping company, as is the audit trail of his work. The appointment certificate, signed, filed, verifiable. Anyone who carries out this triad can pass any traffic or supervisory check without any significant requirements. Practice shows that it is not the individual sticker that is the problem, but rather the lack of a systematic routine with which a sender ensures that every substance, every shipment and every employee function match each other and come together in one file.

The ADR is the international legal basis for dangerous goods labelling. It is updated every two years, most recently in the 2025 version, and is directly German law via the GGVSEB. The regulation regulates who has which obligations: sender (shipper), packer, filler, loader, carrier, recipient. Each of these functions has its own catalogue of duties. Anyone who assigns duties to the other party will still be held responsible in the event of supervision or damage because the law does not define the duty of care in a way that can be delegated.

According to Section 1 GbV, the Dangerous Goods Officer Ordinance requires a dangerous goods officer in all companies whose activities include the transport of dangerous goods or the packaging, loading, filling or unloading associated with the transport. Exceptions apply to small and very small quantities, which are strictly defined by volume and class. Most manufacturing companies, chemical traders, pharmaceutical companies, logistics companies and even many e-commerce shippers regularly exceed this threshold without knowing it.

The stickers themselves are regulated according to ADR Chapter 5.2 for shipments and Chapter 5.3 for large containers and vehicles. Shape, colour, symbol and dimensions are binding. CIVAC maintains the ADR tables, the attachment specifications and the damage levels in the workspace library and links them to the dangerous goods officer mandate. The Dangerous Goods Officer finds the legal basis and the appropriate attachment template in a file. Others run compliance like a filing cabinet. We run it like software. This structured source is the operational basis of every resilient dangerous goods organisation and closes the typical gap between ADR theory and shipping practice. It also makes handovers in the event of employee changes traceable because each substance classification is justified and versioned in the platform. It also ensures consistent representation in the event of illness or vacation of the dangerous goods officer.

The ADR divides dangerous goods into nine classes, some with subclasses. Class 1: explosive substances and articles with subclasses 1.1 to 1.6. Class 2: Gases with subclasses 2.1 flammable, 2.2 non-flammable non-toxic, 2.3 toxic. Class 3: flammable liquid substances. Class 4: flammable solid substances in subclasses 4.1, 4.2 self-igniting, 4.3 producing gases that ignite with water. Class 5: inflammatory substances and organic peroxides in subclasses 5.1 and 5.2.

Class 6: toxic (6.1) and infectious substances (6.2). Class 7: radioactive substances in several categories. Class 8: corrosive substances. Class 9: various dangerous substances and articles, including lithium batteries (UN 3480, UN 3481, UN 3090, UN 3091). Each class has a defined danger label with a symbol, background colour, class number in the bottom corner and a minimum edge length of 100 mm for packages. For large containers and vehicles, a minimum edge length of 250 mm applies, combined with the orange plate and the UN number.

CIVAC maintains a data record for each shipping material in the workspace with the UN number, class, packaging group, danger label, secondary hazard label and special regulations. When the shipping employee calls up the substance, he can immediately see which stickers need to be attached, in which size, in which location and which additional labelling (arrows, environmentally hazardous, limited quantity) will be added. This linkage prevents the most common source of errors: confusion between class and subclass when attaching them manually. If you combine several dangers in one package, such as flammable and toxic liquids, you can see the order of the labels to be attached with the main and secondary dangers directly in the shipping template. The platform also keeps track of ADR updates every two years, so that the master substance database in each shipping release is based on the currently valid version. Special regulations that accompany each class are also stored in the data set for each substance, so that no external research is necessary.

Every dangerous substance has a four-digit UN number, regulated in ADR Annex A Table A. It must be affixed to every package, usually as a UN number preceded by UN: for example UN 1230 for methanol. On large containers and vehicles, the UN number appears in the orange panel, combined with the danger number (Kemler number). Methanol is labelled as 336/1230, where 336 stands for flammable and toxic.

The attachment of the stickers is regulated in Chapter 5.2.2.1 ADR. Shipments carry the danger label on the same side of the packaging as the shipping document. If several dangers need to be marked (main and secondary danger), the labels are placed next to each other. The class number of the secondary hazard in the lower corner is omitted. The UN number is either next to the danger label or as a separate label at a height of at least 12 mm for packages up to 30 liters, and at least 65 mm from 30 liters.

CIVAC links the attachment specifications with the shipping template. The dangerous goods officer keeps an attachment instruction for each substance in the workspace, supplemented by photo examples and measurements. Training for shipping employees is derived directly from these instructions. Audit-proof, documented, ADR-proof. The auditor calls, the evidence is ready. Anyone who outsources shipping can share the instructions with the service provider and have the handover countersigned. This handover logic is provided for in the platform and closes a typical responsibility gap between the sender and the logistics provider. It is also the basis for audit-proof complaint processing because every attachment is stored in the file with the date, responsibility and photo evidence. The photo-documented attachment examples are an effective training tool because they translate the abstraction of the standard into the specific type of package.

The ADR assigns its own duties to each function in the shipping chain. According to Section 18 GGVSEB, the consignor (sender) is responsible for the correct classification, packaging, labelling with danger labels and UN number, the transport document with the correct UN designation and packaging group as well as the training of its own staff. The packer is responsible for the suitability of the packaging, the filler for the correct filling and labelling of tanks.

The shipper according to Section 22 GGVSEB may only load properly labelled and packaged shipments. He checks the correspondence between the transport document and the shipment. The carrier according to § 19 GGVSEB checks the identification of the dangerous goods and the correspondence of the sticker, plate and transport document. The recipient according to § 21 GGVSEB may not refuse acceptance without reason, but must have the transport interrupted and document the incident if there are any abnormalities.

CIVAC maintains a separate file in the workspace for each of these functions. Shipper obligations are linked to the master substance database, shipper obligations to the logistics interface, and carrier obligations to the vehicle file. The dangerous goods officer can see in an overview which duties have which status. Anyone who mandates the external dangerous goods officer receives the distribution of tasks as a signed functional plan, which can be presented immediately in the event of supervision. This distribution of tasks is also crucial in the event of a dispute between the sender and the logistics provider because it clearly defines the boundaries of responsibility and avoids disputes over liability issues. The documented distribution of tasks also acts as proof of proper organisation towards insurers and carrier liability carriers. In the supervisory procedure, the orderly distribution of tasks also forms the basis for exculpation of individual participants without the sender's obligation being eliminated.

Lithium batteries are the most common trap in practice. They fall under Class 9 with UN numbers 3480 (lithium-ion), 3481 (in or packaged with devices), 3090 (lithium metal) and 3091 (in devices). Depending on the size and use, the labelling includes the Class 9A danger label, the lithium battery sticker with the emergency number and UN number and, if applicable, the arrows for the shipping location. E-commerce shippers regularly underestimate these obligations, especially for devices with a built-in battery.

Limited Quantities (LQ) and exempt quantities (EQ) are reliefs under strict conditions. At LQ, a simple diamond sticker is permitted instead of the full danger label, provided that the maximum packaging size per individual package and per package is adhered to. If you use LQ incorrectly, you will lose the relief and therefore mark inadequately. Special cases such as environmentally hazardous substances (fish symbol), heated substances (thermometer symbol) and aerosols require additional labelling.

CIVAC displays these special cases in the workspace library and labels each parent substance with the permissible LQ limit, EQ limit and the required additional labelling. Anyone who licences the workspace trains their shipping staff using the templates. Anyone who chooses the officer-as-a-service model receives annual training from the external dangerous goods officer. Audit-proof, documented, GbV-proof. The FAQ collection answers specific questions about typical shipping cases such as online shipping of power banks, shipping of laboratory samples and the labelling of cleaning products in large containers. The shipping of damaged or returned lithium batteries also follows its own, more strictly regulated path with UN numbers 3171 and 3556 and the associated special regulation. Anyone who regularly ships in large containers also benefits from the automatic check as to whether the permitted total quantities per loading unit according to Chapter 1.1.3.6 ADR are exceeded, which triggers the obligation to provide a complete transport document.

The appointment of a dangerous goods representative is mandatory according to Section 1 GbV. A competent person who has completed IHK training and examination in accordance with Section 4 GbV must be appointed. The order is made in text form and is reported to the responsible IHK. The representative reports directly to the company management and, in accordance with Section 8 GbV, prepares an annual report on the company's activities with regard to the transport of dangerous goods.

The annual report must be kept for at least five years and presented to the responsible authority upon request. It contains an overview of the quantities of substances transported, the training carried out, incidents and near misses as well as recommendations to management. Supervisory authorities, usually the respective regional council or the Federal Office for Logistics and Mobility (BALM), check the annual report during on-site inspections.

CIVAC maintains the annual report as a versioned document in the workspace, with automatic aggregation of the shipping quantities from the substance database, the training data from the personnel module and the incidents from the incident file. The dangerous goods officer does not have to compile the report manually; he checks, supplements and approves it. The appointment certificate, signed, filed, verifiable. In the officer-as-a-service model, CIVAC provides the external representative with IHK expertise and takes over the order with an SLA of 2 working days. Licence the workspace for your internal representatives, or have our representatives order it. Both models lead to the same audit status. The reversibility between licence and delegate models protects against vendor lock-in and enables the function to be gradually internalized as soon as the shipping volume or organisational size makes this economically viable. The annual report is therefore not a mandatory task at the end of the year, but is created continuously from the files maintained.

Chapter 1.3 ADR requires that all persons whose activities involve the transport of dangerous goods are instructed in accordance with their area of ​​responsibility before starting the activity. This includes shipping employees, shippers, carrier staff and recipients. The training must include general awareness, function-specific instruction and safety instruction. It must be repeated, usually every two years. For substances in class 7 (radioactive) and in particularly critical functions, the refreshment intervals are shortened.

The instruction must be documented. In the event of an audit, supervisory authorities check the training certificates with lists of participants, content, duration and qualifications of the training instructor. If proof is missing, this is a reason for complaint with a fine. For drivers, there is also an ADR training certificate in accordance with Chapter 8.2 ADR, which is valid for five years and requires a refresher. Separate construction modules are mandatory for tank vehicles and classes 1 or 7.

CIVAC maintains the training file directly in the workspace. Per employee: training plan, participation, learning success, next refresher. Per training module: content, duration, trainer, qualifications. The platform automatically reports when a refresh is due or a driver certificate is expiring. The dangerous goods officer sees an overview of the training status of all relevant employees. Audit-proof, documented, Chapter 1.3-proof. Anyone who licences the workspace trains themselves. Anyone who chooses the officer-as-a-service model receives the training from an external representative, in person or via video, with prepared modules and learning success monitoring. The training participation rates are stored as KPIs in the management view and support the annual report in accordance with Section 8 GbV. A clearly documented training routine significantly reduces the likelihood of human errors in shipping. This overview also meets the requirements of the professional association, which expects similar proof of training as part of its occupational health and safety examinations.

Incidents according to Chapter 1.8.5 ADR must be reported: death, injury, property damage, environmental damage above a defined threshold. The reporting is made by the company involved to the responsible authority. The dangerous goods officer is responsible for recording, analysing and reporting. Near misses must also be documented internally, even if there is no obligation to report them, because they are crucial for the risk analysis in the annual report. The incident report is made in a defined format with the substance, quantity, course and measures taken.

The transport document according to Chapter 5.4.1 ADR is the central accompanying document. It contains UN number, official shipping name, class code, packing group, number and description of packages, total quantity, consignor, consignee, tunnel restriction code if applicable. Errors in the transport document are one of the most common reasons for complaints during traffic controls. A platform with a master substance database generates the transport document automatically and prevents the most common error class. There are also mandatory accompanying documents such as written instructions for drivers and an emergency information sheet.

CIVAC connects incident files, transport documents and substance databases in one workspace. If a spill occurs in logistics, the dangerous goods officer can immediately see which substance is affected, which first aid measures the safety data sheet specifies, which reporting requirements exist and the training levels of the affected employees. Audit-proof, documented, § 8 GbV-proof. This link is the decisive lever in the stress test of an emergency and reduces the reaction time from hours to minutes, which can make the difference between controlled containment and an escalated incident in the event of damage. Anyone who has experienced how valuable a complete incident file is to insurers, authorities and press offices will no longer see structured recording as bureaucracy, but as part of corporate resilience. The link with the safety data sheet also provides the basis for first aid information to the fire department, THW and police in the first few minutes.

If you've read this far, you have two options. First: You appoint or retain an internal dangerous goods officer and provide him with a workspace in which he maintains a substance database, transport documents, training courses, incidents and annual reports. Second: You mandate CIVAC as an external dangerous goods representative and have the platform and representative ordered as a package. Both models run on the same German infrastructure with EU data residency. Both use 490 audit templates, several of which are for ADR practice and the annual report according to Section 8 GbV.

The next step is a 30-minute conversation in which the obligations are clarified. Which substances are shipped, in what quantities, in which classes, with which facilities? What training is available, what incidents occurred last year, what is today's labelling practice? After this conversation, you will receive an offer with a fixed price, contract term of 12 months and an SLA of 2 working days. Those who prefer the workspace will receive access within two working days. Anyone who appoints the representative will receive the appointment certificate and the IHK advertisement in the same period.

Licence the workspace for your internal representatives, or have our representatives appointed. Write to info@civac.de or use the contact form and the FAQ collection at civac.de/faq. Turn reading into an assignment. If you initially only use the workspace, you can switch to the officer-as-a-service model at any time. Anyone who starts with the mandate keeps the platform if they later fill their own representative position. This reversibility is the most important decision when purchasing a tool, because dangerous goods obligations remain, they only change their form with the shipping volume. A later changeover takes place without data loss and without a migration project.
