\n

Quick answer:<\/strong> On most export lanes, the plywood crate wins \u2014 but usually not for the reason people assume.<\/strong> Freight is almost never charged on weight alone; carriers bill on weight o<\/em> volume, whichever is greater. A plywood case is typically 30\u201340% lighter<\/strong> y 10\u201315% smaller<\/strong> than an equivalent solid timber crate, so it wins twice: it cuts weight where weight is billed (air freight on dense cargo, full containers against road weight limits) and it cuts cube where volume is billed (air express, LCL). Solid wood still wins on a narrow set of jobs \u2014 very heavy, high-impact, field-modifiable loads. The rest of this guide shows you how to work out which side your cargo sits on.<\/p>\n<\/blockquote>\n\n\n\n

The question behind the question<\/h2>\n\n\n\n

“Which crate is cheaper to ship?” sounds like a question about wood. It is actually a question about how your carrier measures your cargo.<\/strong><\/p>\n\n\n\n

Two crates holding the same machine can produce two very different freight bills, and the difference has almost nothing to do with the freight rate you negotiated. It comes down to three numbers on the packing list: the outer dimensions, the gross weight, and \u2014 the one most shippers never look at \u2014 how much of that weight and volume is the crate itself.<\/strong><\/p>\n\n\n\n

Packaging weight is pure overhead. It is not the product. It earns nothing, protects the product, and is billed at exactly the same rate as the product inside. On a dense shipment, a crate that weighs 120 kg instead of 78 kg is 42 kg of freight paid on nothing, every single time.<\/p>\n\n\n\n

So the honest answer to “which saves more” is: it depends on which limit your shipment hits first.<\/strong> Here is how to find out.<\/p>\n\n\n\n

\n\n\n\n

How each freight mode bills you: weight or volume, whichever is greater<\/h2>\n\n\n\n

Every carrier faces the same physical problem \u2014 a truck, container or aircraft runs out of either weight capacity or space, whichever comes first. So they bill on whichever measure is greater. The rule is universal; only the conversion factor changes.<\/p>\n\n\n\n

Mode<\/th>Billing unit<\/th>Conversion basis<\/th>When losing weight saves money<\/th><\/tr><\/thead>
Air cargo (IATA)<\/strong><\/td>Chargeable weight<\/td>1 CBM = 167 kg<\/strong> (L\u00d7W\u00d7H cm \u00f7 6,000)<\/td>When cargo density is above 167 kg\/m\u00b3<\/strong><\/td><\/tr>
Express courier (DHL\/UPS\/FedEx)<\/strong><\/td>Chargeable weight, per piece<\/td>1 CBM = 200 kg<\/strong> (\u00f7 5,000)<\/td>When density is above 200 kg\/m\u00b3<\/strong><\/td><\/tr>
Sea LCL (groupage)<\/strong><\/td>Revenue ton \u2014 “W\/M”<\/td>1 CBM = 1,000 kg<\/strong><\/td>Only when density exceeds 1,000 kg\/m\u00b3<\/strong> \u2014 i.e. almost never<\/td><\/tr>
Sea FCL<\/strong><\/td>Per container<\/td>Flat rate per box<\/td>Not billed by weight \u2014 but road limits still apply<\/td><\/tr>
Road \/ inland haulage<\/strong><\/td>Loading metres, or axle and gross limits<\/td>EU 40 t (44 t intermodal) \u00b7 US 80,000 lb (~36.3 t) \u00b7 China 49 t (6-axle)<\/td>When the truck, not the container, is the ceiling<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Three consequences follow directly from this table, and they decide the whole debate:<\/p>\n\n\n\n

1. In sea LCL, weight is practically irrelevant.<\/strong> A crate would have to exceed one tonne per cubic metre before weight beats volume. Most manufactured goods sit between 150 and 400 kg\/m\u00b3. Translation: on LCL, cube is the bill, and tare weight is free.<\/strong> If you want to save money on LCL, shrink the box \u2014 don’t lighten it.<\/p>\n\n\n\n

2. In air freight, there is a hard break-even line at 167 kg\/m\u00b3<\/strong> (200 for couriers). Cargo denser than that bills on actual weight, so every kilogram you remove from the crate is a kilogram off the invoice. Cargo lighter than that bills on volume, and removing weight saves nothing at all \u2014 only reducing the outer dimensions helps.<\/p>\n\n\n\n

3. In full containers, weight is a ceiling rather than a rate.<\/strong> You pay the same for a 20 ft box whether it holds 8 or 18 tonnes. But a 20 ft container’s plate payload of roughly 28,000 kg is a number you will rarely be allowed to use: once the box is on wheels, the binding limit is the road. In the US the federal interstate gross limit is 80,000 lb (about 36.3 t) including tractor and chassis, which typically caps cargo in a 20 ft at 17\u201320 tonnes<\/strong>; the EU allows 40 t, or 44 t for intermodal moves; China allows 49 t for a six-axle combination. Packaging weight eats into that allowance directly.<\/p>\n\n\n\n

\n\n\n\n

Where the weight actually goes: crate tare weight<\/h2>\n\n\n\n

Packaging manufacturers’ published figures put a plywood case at roughly 30\u201340% lighter<\/strong> y 10\u201315% smaller<\/strong> than an equivalent solid timber crate, without sacrificing strength or durability. Those are typical values, not guarantees \u2014 actual results depend entirely on design \u2014 but the direction is consistent across the industry, and there are three structural reasons for it.<\/p>\n\n\n\n
