How to Choose the Right Jerry Can for Industrial Products
Capacity, wall thickness, closure, venting and transport classification — what actually decides whether a jerry can works for your product.
A jerry can is not simply a large bottle. The integrated handle, the flat stackable body and the heavier wall exist because these packs are designed to survive a supply chain rather than sit on a shelf. Specifying one well means thinking about handling and transport at least as much as about the product inside.
Start with capacity — and be honest about handling
The common sizes are 1, 5, 10, 20 and 25 litres, with larger formats available.
Capacity is not purely a commercial decision. A 20 litre can of a dense liquid weighs enough that a single person will struggle to pour it accurately, and in practice that leads to spillage, waste and occasionally injury. If the end user has to pour from the pack by hand, the weight when full is a real constraint.
If a large format is genuinely needed but pouring is difficult, a tap or spout fitting changes the equation entirely — the can becomes a dispenser rather than something to be lifted.
Wall thickness follows from load, not from preference
Wall thickness — and therefore the weight of the container — is determined by three things:
Fill density. A litre of a dense chemical weighs considerably more than a litre of a light oil. The container carries that load.
Stacking height. The bottom layer of a pallet stack carries everything above it. Two pallets high and four pallets high are different specifications.
Transport conditions. Long road journeys on rough surfaces impose more stress than short local movements.
Suppliers cannot specify this properly without knowing all three. If you are asked only “what capacity?”, you are being quoted a generic item rather than a specification.
Match the material to the contents
HDPE is standard for jerry cans and handles most industrial liquids, lubricants and agrochemicals well.
For aggressive chemistry, compatibility needs confirming against your specific formulation — concentration and additives matter as much as the base chemical. For anything unusual, a storage trial with sample packs before bulk commitment is the reliable approach. Our guide to packaging for chemical manufacturers covers this in more detail.
If the product is stored outdoors or handled in the field — common for agricultural inputs — UV-stabilised material is worth specifying explicitly rather than assuming.
The closure decides whether the pack leaks
Most jerry can failures in transit are closure failures.
Tamper-evident caps show whether a pack has been opened. Standard for products moving through distribution.
Induction seal liners provide a positive barrier against leakage and evaporation. For volatile or valuable liquids they are usually worth the extra cost.
Vented caps allow controlled pouring from larger packs by letting air in as liquid flows out. On 10 litre and above this makes a real difference to how cleanly the product dispenses.
Tap and spout fittings convert the pack into a dispenser, which is often the practical answer for workshop and institutional use.
Specify the closure and liner together with the container. Quoting them separately is how mismatches happen.
Transport classification is not optional
If your product is classified as dangerous goods for transport, the packaging must meet the corresponding requirements. UN-marked packaging is certified for a specific combination of container, closure and fill — it is not a property of the container alone.
This has to be established at the enquiry stage. Retrofitting compliance after choosing a pack on price generally means starting over.
Stacking and palletisation
The flat-sided design of a jerry can exists to make stacking efficient. When specifying, check how the pack fits your pallet: a can that wastes space on a standard pallet costs you on every shipment, and that recurring cost quickly exceeds any per-unit saving.
Recessed handles and interlocking features affect stability in a stack. Worth asking about if your packs travel long distances.
What to include in your enquiry
- Capacity, and what the liquid is
- Fill density, or the product name if it is standard
- Stacking height in your warehouse and in transit
- Transport route and approximate distance
- Whether the product is classified as dangerous goods
- Whether the end user pours, or whether a tap is needed
- Monthly quantity, and whether it repeats
With that, a supplier can specify properly. Without it, you get a price for a generic can — which may be the cheapest quote you receive and the most expensive one you accept.
Request a quote with those details and we will come back with a specification rather than a price for a nominal item.
Frequently asked questions
What wall thickness do I need for a 20 litre jerry can?
It depends on the density of your liquid, the stacking height and the transport route. A dense chemical stacked three pallets high on a long road journey needs more material than a light liquid moving locally. Share those details and the specification follows from them.
Do I need UN-certified jerry cans?
Only if your product is classified as dangerous goods for transport. Certification applies to a specific combination of container, closure and fill, so it has to be specified from the start rather than added later.
Why do some jerry cans have vented caps?
Venting lets air in as liquid pours out, which prevents the glugging and splashing that happens when a large container tries to pour through a small opening. On 10 litre and larger packs it makes a noticeable difference to how cleanly the product dispenses.
