Used 40ft Shipping Container: The Complete Buying Guide

Why choose a used 40ft shipping container?

The used 40ft Dry shipping container is one of the most cost-effective storage solutions on the market. With a nominal length of 12.192 m and an internal volume of around 67 m³, it offers nearly 28.3 m² of floor space at a price well below that of a new container. Its Corten steel structure and 28 mm marine plywood floor make it a durable investment, capable of withstanding years of intensive use.

This type of container is used by professionals (logistics, construction, agriculture, events) and individuals alike (storage, workshop, conversion project). Its attractive price — the model offered here is listed at €1,450 — is explained by the fact that it has already been used for sea transport, but this does not prevent it from being perfectly functional for land use. You still need to know what you are buying and how to assess the actual condition of the unit.

This guide takes you step by step: standardised dimensions, quality criteria, points to watch, transport, regulations and practical uses. The aim is simple: to help you choose a used 40ft container suited to your project, with no unpleasant surprises.

Technical specifications: what you are actually buying

Standardised ISO dimensions

A 40ft Dry container complies with ISO 668 and ISO 1496-1 standards, which set its external and internal dimensions as well as its structural performance. Here are the reference measurements:

• External length: 12.192 m (40 ft)
• External width: 2.438 m (8 ft)
• External height: 2.591 m (8 ft 6 in) for a standard Dry
• Internal length: approx. 12.032 m
• Internal width: approx. 2.352 m
• Internal height: approx. 2.393 m
• Internal volume: approx. 67.7 m³
• Floor area: approx. 28.3 m²

These dimensions are standardised, meaning all 40ft Dry containers are compatible with each other for stacking and transport. The High Cube (HC) model offers an additional internal height of around 30 cm (2.695 m instead of 2.393 m), but it is generally more expensive and less common. The container offered here is a standard Dry.

Weight and payload

The tare weight of a 40ft Dry container in Corten steel is generally between 3,600 kg and 4,200 kg depending on the manufacturer and year of construction. The maximum payload varies from 26,000 kg to 28,000 kg, and the maximum gross weight is 30,480 kg, in accordance with ISO standards. These values appear on the container's CSC plate and must be checked before any transport.

Materials and construction

The frame is made of Corten steel, a low-alloy steel that resists atmospheric corrosion thanks to the formation of a protective oxide layer on the surface. The side and front walls consist of corrugated steel sheets, welded to vertical posts. The roof is also made of corrugated sheet, reinforced by cross members. The floor is 28 mm marine plywood, treated to resist moisture and heavy loads. It is fixed to steel cross members.

The rear doors are fitted with four locks per leaf (eight in total), with vertical locking bars and handles. Rubber seals ensure airtightness and watertightness. The container can be stacked up to nine units high in maritime configuration, but for land use it is generally placed on blocks or beams to avoid direct contact with the ground and allow ventilation.

Condition and quality: decoding the "used" labels

Not all used containers are equal. The market distinguishes several categories:

• One-trip: almost new, having made a single voyage. High price.
• Cargo worthy: suitable for sea transport, structurally sound and certified.
• Wind and watertight: airtight and watertight, suitable for land storage.
• As is: sold as is, possibly with more or less significant defects.

The 40ft container offered is of cement storage quality, i.e. a robust container often used in the construction sector, and airtight and watertight. This means it has no water leaks in the roof, walls or doors, and the seals are in good condition. Traces of surface rust, scratches, dents or repair marks may be present without compromising structural integrity.

The 28 mm marine plywood floor is checked to ensure it has no rotten or sagging areas. The doors must open and close correctly, with functional locks. It is advisable to inspect the container before purchase, or to request recent photos and a precise description of its condition.

A used container may have been used to transport various goods; thorough cleaning is recommended before using it for sensitive storage (food, textiles, etc.). If the container has carried chemicals or hazardous products, it must be decontaminated according to appropriate procedures. We do not provide a detailed history of previous cargoes, but we can guide you towards professional cleaning solutions.

Points to watch before buying

Before confirming your purchase, methodically inspect the following:

1. Structure: check that the corner posts, top and bottom rails, and corner castings are not cracked or deformed. These elements are essential for stability and lifting.
2. Watertightness: inspect the roof and walls for holes, perforating rust or traces of infiltration.
3. Doors: they must open and close without force, and the seals must be flexible and properly in place.
4. Floor: it must not be soft, rotten or have missing boards.
5. Modifications: if the container has been modified (openings, partitions), make sure this has not compromised its structure.
6. Treatment: ask whether the container has been treated against pests (termites, rodents) and whether it has been cleaned.
7. CSC plate: it certifies the container's compliance with safety standards and indicates its manufacturing date and maximum weights. It must be legible and up to date.

If you are buying for maritime use, the container must be certified "cargo worthy"; for land use, a "wind and watertight" container may suffice. Finally, compare prices: a used 40ft container can vary depending on its condition, age and availability. A price that is too low may hide significant defects. Do not hesitate to ask for detailed photos and, if possible, to visit the container before purchase.

Common uses: what is a 40ft Dry for?

Storage and logistics

The 40ft Dry container is versatile. For storage, it can hold palletised goods, construction materials, furniture, industrial equipment, agricultural products (grain, fodder, fertiliser), light vehicles or spare parts. Its great length allows a forklift to enter, making loading and unloading easier.

For Euro pallets (1.20 m x 0.80 m), around 20 to 25 pallets can be stored on the floor, and up to 40 when stacked on two levels, subject to available height and floor strength.

Construction sites

On construction sites, it serves as a tool store, technical room, changing room or site office after basic fitting out. Its length allows partitions to be installed to separate several spaces (canteen, office, meeting room).

Agriculture

In agriculture, it is used as a storage shed for hay, seeds, equipment, or as shelter for livestock after modification. Winegrowers can store bottles or equipment in it. Farmers store livestock feed in it.

Individuals and conversion projects

For individuals, it can become a garden storage space, a DIY workshop, or even a base for a modular housing or tiny house project, subject to insulation, ventilation and interior fitting work. The container can also be converted into a commercial premises, a fixed food truck, a gym, a recording studio, etc. Its modularity and robustness make it a cost-effective solution for many projects.

It is important to note that use as housing or premises receiving the public requires compliance with local construction and planning rules (building permit, fire safety standards, accessibility, thermal and acoustic insulation). The raw container is not designed to be habitable as is: insulation, heating, ventilation and possibly interior cladding must be provided. Similarly, for food or pharmaceutical use, specific hygiene standards apply.

Comparison with other container sizes and types

The 40ft Dry container differs from the 20ft by its roughly double capacity (67 m³ versus 33 m³). The 20ft is more manoeuvrable, lighter and easier to transport, but offers less space. The 40ft is more suited to storing large volumes and fitting out living or working spaces.

The 40ft High Cube (HC) container offers an additional internal height of around 30 cm (2.695 m instead of 2.393 m), which can be an advantage for storing tall goods or fitting an insulated ceiling. The standard 40ft Dry container is more common and generally cheaper than the High Cube.

The 40ft Open Top container has an opening (tarpaulin) roof to load out-of-gauge goods from above, but it is less watertight and more expensive. The Flat Rack container has no side walls or roof; it is used for heavy or bulky loads. The Reefer container is refrigerated and allows perishable goods to be transported, but it is more expensive and requires a power supply. Finally, the 45ft container is an extension of the 40ft, with an internal length of around 13.556 m, but it is less common and harder to transport. The choice between these different types depends on the intended use, budget and transport and installation constraints.

Transport and regulations in France

Road transport

Transporting a 40ft container in France is subject to heavy goods vehicle regulations. A 40ft container is 12.192 m long, which exceeds the maximum length allowed for a standard articulated vehicle (16.5 m for a tractor + semi-trailer combination). Transporting a 40ft container therefore requires a suitable vehicle (container semi-trailer) and may be subject to traffic restrictions (hours, routes, dimensions). The maximum authorised gross combination weight must not exceed 40 tonnes for a standard road train, and the container weight (tare + load) must be taken into account.

For lifting, a full 40ft container can weigh up to 30 tonnes; an appropriate lifting device is therefore required (mobile crane, high-capacity forklift). Transport must be carried out by a qualified professional, with the necessary authorisations (abnormal load convoy if dimensions are exceeded).

Installation and planning

For installation on private land, local planning rules should be checked: in some municipalities, installing a container may be considered a construction and require a building permit or prior declaration. It is advisable to contact the town hall's planning department. Moreover, if the container is intended for housing, it must comply with construction standards (insulation, fire safety, accessibility).

Finally, if the container is imported from a country outside the European Union, customs duties and taxes may apply, as well as health and plant health checks.

Care and maintenance: extending service life

To extend the life of a used shipping container, regular maintenance is necessary. The roof, walls and floor should be inspected annually to detect any corrosion, perforation or infiltration. Small areas of rust can be treated with a wire brush and anti-rust paint suitable for Corten steels. Door seals should be cleaned and possibly replaced if cracked or hardened. Locks and hinges should be lubricated to prevent seizing.

The wooden floor can be cleaned with a mild detergent and treated with a water-repellent product to prevent moisture absorption. If the container is used to store moisture-sensitive products, it is recommended to install a dehumidifier or moisture absorbers, as condensation can form inside due to temperature variations. Adequate ventilation is also important to prevent mould.

For outdoor use, it is advisable to raise the container on blocks to avoid direct contact with the ground, which limits corrosion from below and allows air circulation. If the container is exposed to sea spray, periodic rinsing with fresh water can help reduce corrosion. Finally, if modifications are made (drilling, welding), care should be taken to protect exposed areas with suitable paint.

Budget and value for money

The used 40ft Dry container listed at €1,450 represents an attractive entry point. This price corresponds to a cement storage quality container, airtight and watertight, with normal traces of wear. For comparison, a new or one-trip container generally costs two to three times more. A used 20ft container is often offered at around €1,000 to €1,200, but it offers half the volume.

The total budget must include transport and handling. Delivery of a 40ft requires a container truck with crane or a suitable forklift. The cost varies depending on distance and access conditions. Also allow sufficient manoeuvring space for unloading.

Finally, bear in mind that a well-maintained used container can serve for several decades in land use. Value for money is therefore excellent, especially if you do not need a container certified for sea transport.
