CKD vs SKD Assembly: Which Import Format Fits Your Operation

CBU, SKD and CKD are not just shipping preferences — each format changes freight cost, import duty, local assembly work and spare-part logistics. This guide compares them for three-wheeler buyers and helps you pick the format that fits your market.

The three formats in one line

CBU (completely built unit) ships the finished vehicle. SKD (semi-knocked-down) ships major sub-assemblies — body, drivetrain, wheels — for local assembly. CKD (completely knocked-down) ships parts and components for full local assembly.

Freight and duty

In many markets, knocked-down formats reduce freight volume and can attract lower import duty than finished vehicles. The savings depend on the destination tariff schedule — your customs broker should calculate the landed cost difference before you choose.

Local assembly requirements

SKD needs a workshop, basic tools and trained staff for final assembly and testing. CKD needs more space, more skill and a stronger quality process. If local content or assembly is required to qualify for duty benefits, CKD often satisfies that requirement better.

Which format suits which buyer

New operators usually start with CBU to get vehicles running fast. Distributors building a market position often move to SKD, then CKD as volume grows. Government or institutional buyers sometimes require local assembly as a condition — plan the format before the contract, not after.

Spares and support

Knocked-down formats naturally create a local parts inventory, which is an advantage for after-sales. Confirm the spares list, assembly manual and support documents when you order — they should be itemized on the proforma invoice like everything else.

The short answer

CBU to start, SKD to scale, CKD to industrialize. Confirm the duty and assembly economics for your market before choosing, and put the format, parts list and assembly support in writing.
