Fully assembled or knocked down: shipping choices that matter

For bulky items like electric cargo tricycles, industrial equipment, or prefabricated components, the shipping mode can drive 30% to 50% of the landed cost difference between two otherwise identical products. Fully assembled (CBU) is faster to deploy but takes more volume. Knocked down (CKD) is cheaper on freight but requires local assembly capacity.

A worked example from a Thailand tricycle pilot

Solar electric cargo tricycles at distributor pricing of USD 1,450 to USD 2,900 typically carry USD 400 to USD 800 of freight per unit as CBU, depending on destination. Shipped as CKD, that freight drops to USD 200 to USD 400. On a 20 unit pilot that is a USD 4,000 to USD 8,000 swing, which is more than enough to fund a local assembly partnership in country.

The catch is that CKD requires a local partner with the mechanical skills to assemble the unit, access to replacement parts, and an after sales relationship. For pilots where the distribution partner is unproven, CBU is often the right choice even at higher freight cost. It moves the operational risk onto the shipper rather than the new distributor.

Where CKD makes sense

• Repeat volume to an established distributor with local assembly capability
• Destination markets with freight cost that is a significant share of unit cost
• Products with simple mechanical assembly and well documented SOPs
• Containers where volumetric weight rather than actual weight drives freight pricing

Where CBU makes sense

• Pilot orders where destination assembly is unproven
• Products with complex calibration or firmware commissioning
• Short delivery windows where local assembly adds unacceptable lead time
• Buyer demos, trade shows, and initial market validation batches

What we ask every buyer to model

Before committing to a shipping mode, we ask the buyer to model the all in landed cost on both sides, including local assembly labor, local parts inventory, and the shipping cost difference. The answer is often counterintuitive. CKD looks cheaper at first, but once local assembly and warranty risk are priced in, CBU is sometimes the better choice for the first three to six months.
