Regulations for Shipping Flammable Aerosols by Courier
No, a flammable aerosol cannot be sent via standard courier in Spain. It is classified as dangerous goods (UN 1950, class 2) under the ADR agreement and can only be moved by carriers certified for hazardous materials, or by using the limited quantities (LQ) exemption, which reduces requirements but does not eliminate marking or weight limits.
Why a Flammable Aerosol Cannot Be Sent in a Standard Package
A flammable aerosol combines a pressurized gas with a combustible propellant, making it dangerous goods for transport purposes. The Spanish public postal operator explicitly states this in its shipping conditions: items not permitted in the postal network include compressed gases such as lighters, diving tanks, camping gas, aerosols, or fire extinguishers, along with explosive, flammable, and other dangerous materials, except for very specific exceptions related to laboratories or authorized radioactive materials, according to Correos.
This restriction is not exclusive to Spain. The Universal Postal Union reminds that the international postal network prohibits moving goods categorized as dangerous, specifically citing aerosols and other compressed gases, lighter fluids, perfumes, and other flammable products. The technical reason is simple: a package that is mishandled, crushed, or exposed to high temperatures in a logistics warehouse can release the propellant and generate an ignition source.
Which Regulations Govern the Transport of Aerosols in the European Union
The legal framework combines two layers. The first regulates the product itself: Directive 75/324/EEC on aerosol dispensers, amended by Directive 2013/10/EU to align labeling with the CLP Regulation. This rule requires any aerosol classified as flammable or extremely flammable to include the flame symbol and corresponding hazard statements on the container.
The second layer regulates the physical movement of the product: the ADR Agreement on the international carriage of dangerous goods by road, which Spain also applies to national traffic. Under this agreement, aerosols are coded as UN 1950 within class 2 (gases), with variants depending on their level of flammability and toxicity, as recorded in the MyONU technical search engine for ADR data sheets.

Are There Any Exceptions for Shipping Aerosols Without an ADR Carrier?
Yes, and it is the route used by most companies moving small volumes of aerosols: the limited quantities (LQ) exemption. Chapter 3.4 of the ADR allows the transport of dangerous goods in small inner packagings within a combined outer packaging, with much lighter requirements than the full ADR regime, as explained by Quimi-Reach regarding this mechanism.
For aerosols, the usual limit is one liter per individual container, grouped up to a maximum gross weight of 30 kg per package, marked with the characteristic black-tipped diamond, according to the technical details published by LocisADR. Below that threshold, there is also the excepted quantities (EQ) exemption, designed for even smaller volumes, common in the shipping of perfumes, aerosols, and cosmetics as indicated by Rafael Chinchilla, ADR training specialist.
💡 Manufacturer's tip: if your company needs to move aerosols regularly, always ask your logistics operator for the document proving whether they operate under LQ, EQ, or full ADR, because each regime sets a different quantity limit and a classification error can halt the shipment in transit.
What Happens if You Ship a Flammable Aerosol Without Declaring It
Hiding or failing to declare the dangerous nature of a shipment does not eliminate the risk; it transfers it to the logistics chain without anyone knowing. General courier companies expressly exclude this type of merchandise from their coverage and warn that they do not accept claims resulting from delays or incidents due to incorrect ADR packaging or prohibited goods, as Packlink notes in its shipping conditions.
In addition to the risk of fire in warehouses and vehicles, an undeclared shipment may be held, destroyed, or returned, and exposes the sender to liability for non-compliance with dangerous goods transport regulations. ADR regulations do not distinguish between an individual sending a leftover can and a company moving pallets: if the content meets the parameters of a flammable aerosol, the same classification rules apply.
Aerosols and other compressed gases, lighter fluids, perfumes, matches, and other flammable products cannot be sent through the international postal network.
Who Can Legally Transport Flammable Aerosols in Spain
This can only be done by carriers operating under the ADR regime, whether full or under the LQ or EQ exemptions described above. This involves vehicles, packaging, labeling and, in the case of full ADR, personnel with specific training and a safety advisor—conditions that are beyond the scope of a conventional courier or parcel service designed for ordinary packages.
For a manufacturer that produces and ships aerosols on a large scale, this is not a one-off logistics decision but part of their supply chain design: it requires selecting certified carriers from the source and coordinating product labeling with shipping packaging right from the plant.
