The guide that, in Spain, no perishable goods transporter can ignore

The road transport of perishable goods is no ordinary task. Behind every load of frozen fish, raw milk, or minced meat lies a stringent set of regulations that, if ignored, can become a headache with fines to match. The Manual for the Inspection of the Transport of Perishable Goods, published by the Ministry of Transport, Mobility and Urban Agenda, is the go-to document for inspectors and transporters, and its content leaves no room for improvisation. Based on the ATP Agreement — the international treaty that has harmonised these operations since 1976 — the manual makes it clear that both international and domestic journeys are subject to the same rules, thanks to the transposition of Royal Decree 1202/2005.

The first thing that stands out is the complex classification of vehicles. Not just any truck or trailer will do: the units are divided into isothermal, refrigerating, mechanical refrigerating, heating, or combined, and each has its own identification marking and a thermal transmission coefficient (the famous K coefficient) that must be equal to or less than 0.70 W/(m²•K) for normal units, and 0.40 for reinforced ones. A class B refrigerated unit, for example, must be able to maintain any temperature between +12 °C and -10 °C, while a class F unit goes down to -20 °C. It all depends on the product being carried, and the manual offers detailed tables to avoid mistakes.

But it is not enough for the vehicle to have the technical capability; compliance must be certified. Before hitting the road, each unit must pass an initial inspection and undergo periodic checks at least every six years, not to mention the surprise inspections that the competent authority may order. The certificate of conformity, issued by the country of registration, is the mandatory pass that must always travel on board. However, if the unit has the certification plate fitted — a rectangular, fire-resistant and corrosion-resistant plate of at least 160×100 mm — that plate is equivalent to the certificate, as long as it is valid and visible.

Identification markings are another chapter that cannot be overlooked. In dark blue capital letters on a white background, they must appear on both sides of the vehicle, in the upper corners and near the front. Their minimum size is 100 mm for the letters and 50 mm for the expiry date, except on light vehicles of less than 3.5 tonnes, where they are halved. In addition, each isothermal body and each thermal device must bear the manufacturer’s plate with the country, name, type, serial number, and month and year of manufacture. Since October 2020, these markings have been mandatory on all new units, and any error in their placement or absence is already grounds for a penalty.

When the cargo consists of deep-frozen or frozen products, the requirements increase significantly. The manual sets strict maximum temperatures: -20 °C for ice cream, -18 °C for fish, seafood and other deep-frozen products, -12 °C for other frozen goods (except butter, which allows -10 °C). And there is no room for complacency: the unit must be equipped with a thermograph to measure, record and store ambient temperature data in accordance with the EN 12830 standard, and the carrier is obliged to keep those records for at least one year. If the doors are opened during an inspection, extreme care must be taken not to break the cold chain, and only a temporary 3 °C rise during evaporator defrosting is tolerated.

For refrigerated goods, the maximum temperatures are equally strict: raw milk at +6 °C, red meat and large game at +7 °C, meat products and fresh dairy products at +6 °C or the temperature indicated on the label, poultry and small game at +4 °C, red offal at +3 °C and minced meat at +2 °C. Any temperature check must follow the procedure in Annex 2 of the ATP, and opening the doors during an inspection requires maximum care to avoid exposing the goods to conditions that could compromise their preservation. The manual reminds us that these limits are not guidelines, but legal obligations that must be met throughout the entire journey.

And if something goes wrong, the consequences are clearly graded. Very serious offences, such as transporting deep-frozen goods without the thermograph installed, carry heavy penalties and fall on the carrier. Serious offences, such as using a vehicle without a certificate of conformity or with one that has expired, involve liability for both the carrier and the consignor. Minor offences, such as not carrying the certificate on board or placing the identification markings in improper places, also result in fines and can lead to the immobilisation of the vehicle. All of this is covered by the Land Transport Regulation Act, and the manual serves as a reminder that compliance is not a suggestion.

The final warning is clear: no carrier can afford to ignore this document. The ATP regulations are updated periodically — the last major revision came into force in July 2020 — and what was valid yesterday may not be today. Knowing the classifications, markings, certificates, temperatures and offences is not an extra; it is an essential condition for operating legally and avoiding financial losses and reputational damage. The manual is within everyone’s reach, and in a sector where the cold chain is life, information is the best ally for travelling safely and without surprises.
