Transporting dangerous goods is indispensable for countless industries, from chemicals and high-tech to medical technology. But where dangerous goods travel, there are also risks: leaks, fire, environmental damage or supply chain downtime. This is precisely why ADR exists, the international agreement that prescribes how dangerous goods should be packed, labeled and transported by road.
ADR is not a theoretical rulebook. It determines in practice which packaging may be used, how it must be tested and certified, and which markings and labels are required. As of Jan. 1, the latest version, ADR 2025, applies. Those still working with outdated markings or unapproved packaging run great risks of fines, claims and delays.
So the question is not whether ADR is relevant to your packaging processes, but how prepared you are for the requirements that are already in place. In this article, you will read what ADR means, what obligations apply specifically to packaging and why compliance is essential to keep your supply chain safe, compliant and future-proof.
ADR stands for Accord européen relatif au transport international des marchandises dangereuses par route. Freely translated, this is the European Agreement for the International Carriage of Dangerous Goods by Road. The treaty was drafted in Geneva in 1957 under the supervision of the United Nations and has since been administered by the UN Economic Commission for Europe (UNECE).
The ADR has one goal: to ensure safety for people, the environment and infrastructure when transporting dangerous goods. This includes liquid and solid substances as well as objects that may pose a hazard due to their properties. Examples include flammable liquids, toxic substances, lithium batteries and gas cylinders.
It is binding on all signatory member states, including the Netherlands and virtually all other European countries. A new version is published every two years, updating technical requirements and safety regulations. Since Jan. 1, the ADR 2025 edition has been in effect. Companies were still allowed to apply the previous version (ADR 2023) until June 30, 2025, but since then compliance with the new regulations has been mandatory.
For packaging, this means they must comply with specific testing standards, UN markings and labeling rules established by ADR. This makes ADR the basis for safe and compliant packaging within the industrial supply chain.
One of the most important pillars of ADR are packaging requirements. These govern not only how dangerous goods are safely packaged, but also how packaging must be tested, certified and marked. Specifically, for industrial packaging, this means three things: UN type approval, labeling and compatibility.
Packaging used to transport dangerous goods must bear a UN mark. This code shows that the packaging has been tested and approved according to ADR regulations. The code states, among other things:
This marking proves that the packaging has been tested for drop resistance, pressure, leak tightness and stackability. Without UN type approval, the packaging may not be used for ADR transport.
In addition to marking, ADR requires dangerous goods to be visibly labeled. Proper hazard labels must be applied to packages, with a minimum size of 100 × 100 millimeters. Larger labels of 250 × 250 millimeters apply to larger transport units such as vehicles and containers. These labels directly indicate which hazard class the product belongs to, such as flammable, toxic, corrosive or environmentally hazardous.
Not every package is suitable for every substance. ADR requires that the packaging used must be compatible with its contents. This means that the packaging must be resistant to chemical reactions or physical behavior of the substance or object. If in doubt, additional tests must be performed.
The rules of ADR may sometimes seem abstract, but they have direct implications for the day-to-day operations of companies that pack and transport dangerous goods.
Those who fail to comply with ADR requirements face significant risks:
ADR compliance requires more than just good packaging. It requires a chain-wide approach: correct classification of substances, proper documentation, well-trained personnel and control of reused packaging. Companies that organize this well not only prevent risks, but also realize predictability and continuity in their logistics processes.
As a partner, Faes supports companies in making and keeping their packaging fully compliant. This starts with the design of customized packaging that meets the appropriate UN testing standards and continues through to the management of labeling, traceability and documentation. Faes also coordinates maintenance, cleaning and reuse of packaging so that even repeated shipments remain ADR-proof.
In doing so, we not only remove operational concerns, but also help organizations move forward strategically. By integrally managing packaging, we minimize the risk of non-compliance and create insight into costs, material flows and recycling. In this way, ADR compliance does not become an onerous obligation, but part of a safe, efficient and future-proof supply chain.
ADR is much more than a collection of rules. It is the foundation that ensures dangerous goods can be transported safely and responsibly, without risk to people, the environment and business continuity. For industrial packaging, this means that every choice, from design and material to marking and labeling, determines compliance and safety.
Those who underestimate ADR risk fines, transportation stoppages and reputational damage. Instead, companies that have their packaging and processes in order benefit from predictability, safety and more efficient logistics. This makes ADR compliance not only a legal obligation but also an opportunity to make the supply chain stronger and more sustainable.
As a partner, Faes helps organizations make that translation. From developing UN-approved packaging to managing labeling, traceability and reuse, we ensure packaging meets ADR requirements and contributes to a safe, future-proof supply chain.
The question is not whether you should start working with ADR, but how quickly you set your organization up for it. Companies that take the right steps today avoid problems tomorrow and create a lasting competitive advantage.
