If you export machinery, equipment or project cargo out of Western Australia, the packaging decision usually starts with one question: does your cargo need an open slatted timber crate, or a fully enclosed case? Both are proven export packaging solutions, both can be manufactured to ISPM-15 quarantine standards, and both move through Fremantle Port by the thousands every year. But they solve different problems, and choosing the wrong one can mean paying for protection you do not need, or arriving at the destination with damaged cargo.
With Fremantle Port handling the bulk of WA’s containerised trade and the state’s mining sector shipping everything from pump assemblies to full processing modules overseas, export packaging is not a minor detail. This guide compares open slatted timber crates against enclosed wooden cases and plywood cases across the factors that matter most to WA exporters, so you can make the call with confidence.
Open Slatted Timber Crates Built for Export Logistics
An open slatted timber crate is a heavy-duty wooden shipping crate built from solid structural timber, with spaced slats rather than solid cladding. The framework carries the load, making timber crates ideal for dense, heavy and odd-shaped cargo such as mining equipment, fabricated steel, valves, motors and machinery components moving through demanding storage and transport environments.
Features
- Customisable Design: Built to suit cargo size, weight distribution, and lifting requirements, with bespoke designs supporting cargo up to 30 tonnes.
- Open Slatted Construction: Provides ventilation and allows easy cargo inspection during handling and quarantine checks.
- ISPM-15 Certified Timber: Heat-treated timber compliant with international export regulations.
- Forklift & Crane Compatible: Designed for safe lifting, container loading, and freight handling.
Because the cargo remains visible through the slats, open crates suit shipments where inspection access matters, or where the goods are robust enough that full enclosure is unnecessary.
Enclosed Cases: Solid Wooden and Plywood Options
An enclosed case fully surrounds the cargo with solid panels, shielding it from dust, moisture, handling contact and view. Within this category, WA exporters choose between two constructions depending on cargo weight and freight economics.
Enclosed Wooden Cases
Wooden cases combine the structural strength of solid timber with complete panel coverage. They are the right choice when cargo is both heavy and sensitive: export machinery, large plant, and high-value fabricated equipment that needs full protection from the elements without giving up load capacity.
Enclosed Plywood Cases
Plywood cases use lightweight plywood panels over a timber or steel frame. Lower tare weight directly reduces air and sea freight costs, making them the go-to for light to medium loads: electronics, instrumentation, precision-machined parts and critical spares.
Features of Enclosed Cases
- Full Enclosure: Shields cargo from dust, moisture, handling contact and view.
- Smooth Uniform Exterior: Stacks cleanly in containers and accepts shipping marks and handling symbols.
- Preservation Ready: Compatible with VpCI corrosion inhibitors, desiccants and sealed barrier films for sensitive metal components.
- ISPM-15 Compliant Construction: Available for international export shipments.
Open Crates vs Enclosed Cases: Side-by-Side Comparison
| Factor | Open Slatted Timber Crates | Enclosed Wooden Cases | Enclosed Plywood Cases |
| Load capacity | Excellent for heavy and dense cargo, up to 30 tonnes | Excellent for heavy cargo needing full cover | Best for light to medium loads |
| Cargo protection | Structural protection, open to air and dust | Full solid timber enclosure | Full enclosure with lightweight panels |
| Tare weight | Lighter than a fully clad crate of the same size | Heaviest of the three | Lightest fully enclosed option |
| Inspection access | Easy visual inspection through slats | Requires opening the case | Requires opening the case |
| Ventilation | Natural airflow, reduces condensation risk | Sealed, pair with desiccants or VpCI | Sealed, pair with desiccants or VpCI |
| Security and privacy | Contents visible | Contents concealed | Contents concealed |
| Typical WA cargo | Robust machinery, fabricated steel, castings | Heavy sensitive plant, export machinery | Instrumentation, electronics, spares |
| ISPM-15 export compliance | Available | Available | Available |
| Cost efficiency | Strong value for robust heavy cargo | Strong value for heavy cargo needing enclosure | Strong value where freight weight drives cost |
When to Choose an Open Slatted Timber Crate
Open slatted timber crates are the right call for most heavy industrial export shipments leaving Perth. Choose an open crate when:
- Your cargo is heavy or dense. Solid timber framing handles the point loads and lifting stresses that mining equipment and machinery generate.
- Ventilation matters. Open slats let air circulate, reducing condensation on metal surfaces during long sea voyages.
- Inspection access is required. Customs and quarantine inspections are faster when officials can sight the cargo without unpacking.
- The goods are inherently robust. Castings, steelwork and skid-mounted equipment rarely need full enclosure.
- Handling will be rough or repeated. Cargo moving from a Kewdale packing facility to Fremantle Port, onto a vessel, and then to a remote site overseas gets lifted many times. Structural timber absorbs that punishment.
When to Choose an Enclosed Case
Enclosed cases earn their keep when the cargo needs to be sealed away from the environment. Choose an enclosed case when:
- The cargo is sensitive. Electronics, instrumentation, coated surfaces and precision components need protection from dust, moisture and handling contact.
- Corrosion is a risk. A sealed case paired with VpCI preservation or desiccants creates a controlled environment for long voyages through humid climates.
- Discretion matters. Enclosed cases conceal high-value contents from view during transit and storage.
- You need clean stacking and marking. Flat panel surfaces stack efficiently in containers and display shipping marks clearly.
Then pick the construction: solid wooden cases for heavy cargo that needs enclosure without compromising load capacity, and plywood cases for lighter goods where every kilogram of tare weight adds to the freight bill, especially on air freight.
The Decision Checklist
Run your shipment through these six questions before you order:
- Does the cargo need full enclosure? If it is sensitive to dust, moisture or contact, start with an enclosed case. If it is robust, an open slatted crate is usually the better value.
- How heavy is the cargo? Heavy loads point to solid timber, either an open crate or an enclosed wooden case. Light to medium loads open up the plywood option.
- How is freight being charged? If you are paying by weight, especially air freight, a lighter plywood case may pay for itself.
- Will the shipment face quarantine or customs inspection? Open slatted timber crates make inspections quicker.
- How long is the journey, and through what climates? Long humid voyages favour either ventilated open crates or sealed cases with corrosion protection, depending on the cargo.
- Is the destination international? Either way, specify ISPM-15 certified timber so your export packaging clears quarantine without delays or re-packing.
If your shipment sits between categories, do not force it into a standard design. Custom-built export packaging matched to your exact cargo dimensions, weight distribution and lifting requirements almost always outperforms an off-the-shelf compromise.
