Vehicle duties are high, so the idea of importing knock-down kits and assembling locally appears. It genuinely can cut duty — but it is not a simple saving tool. Get it wrong and assembly costs eat the entire duty benefit. Here is how to run the numbers.
1. Cost Differences Between Import Forms
| Form | Duty level | What else you invest |
|---|---|---|
| CBU (complete) | Highest | Pre-delivery inspection only |
| SKD (semi-knock-down) | Medium | Simple assembly space and labour |
| CKD (full knock-down) | Usually lowest | Welding, painting, final assembly space, tooling and skilled staff |
The core test: duty saved must exceed the added cost of people, premises, equipment, inventory and process losses — otherwise the model does not work.
2. Four Preconditions
- Is annual volume large enough? An assembly line's fixed cost needs volume to amortize; small markets should not jump straight in.
- Localization requirements: many countries grant duty benefits on local value added — model the phase at which you qualify.
- A credible partner: assembly quality depends on process discipline. Choose partners with manufacturing management experience, not the cheapest quote.
- Parts and shortage response: one missing bolt stops the line — can your supplier feed it to takt time?
3. Hidden Costs Buyers Forget
- Packaging and transit damage: knock-down parts need far stronger protection than complete cars; high damage rates wipe out the duty saving.
- Inventory capital: kits carry multi-layer BOMs — many SKUs, slower turns, more cash tied up than complete vehicles.
- Quality consistency risk: inconsistent assembly triggers concentrated warranty failures and heavy aftersales costs.
- Approval responsibility: decide and document who holds and handles approval for locally assembled vehicles.
Shunwei Auto tip: For a first attempt, start with SKD — lower investment, faster payback. Validate the partner's assembly quality and supply rhythm before upgrading to full knock-down.
Note: Customs classification and duty treatment of knock-down parts vary widely by country; the same parts can attract different codes. Get a written opinion from your local broker before committing.
