Vietnamese E-Bike Assembly: Preference, Circumvention and Customs Value
An EU cycling brand owns a wholly owned assembly plant in Vietnam that builds 12,000 e-bikes a year for the European market. The Vietnamese plant buys the frame (€88), motor (€112), display and controller (€34) and rims, forks and handlebars (€46) from Chinese suppliers, and invoices the brand €360 ex-works, made up of €280 of Chinese parts and €80 of assembly labour and overhead. The brand buys the Korean battery (€150) and the remaining EU components (€45) itself and ships them free of charge to the plant; international freight and insurance to Rotterdam is €25 per unit. Customs declarations use the €360 invoice value. Two pressures converge: the brand's broker warns that the EU has opened an anti-circumvention investigation into e-bikes assembled in Vietnam, with the 62.1% residual anti-dumping duty on Chinese-origin e-bikes potentially extended, and a post-clearance audit notice has arrived covering the past three years. Management believes EU–Vietnam FTA preference settles the matter.
1. Does Vietnamese assembly confer preferential origin, and does that protect the brand from anti-dumping duties?

Separate the two legal questions, because management has merged them. Preferential origin under the EU–Vietnam agreement is a tariff-classification test applied to the product-specific rule, normally a change of tariff heading. Parts of e-bikes sit under heading 8714 and the complete e-bike under 8711, so assembling the parts into a finished bike generally satisfies that rule and preference is likely available. That is a tariff outcome of a few percentage points.
Anti-dumping origin is a different test. Measures are applied to goods originating in the country subject to the duty, and where assembly is used to route around a duty, the authorities examine the value of parts originating in the duty country and the value added by the assembly operation. Here, Chinese parts are €280 of €475 of total parts value, about 59%, and assembly adds €80 to a full product cost of roughly €555 - around 14%. Both indicators sit in the danger zone: one just under a typical threshold, the other low in value-added terms.
Conclusion: preference is probable; protection is not. Preference reduces the MFN duty on a few per cent and does nothing against a 62.1% anti-dumping duty. Treating FTA qualification as the answer to the circumvention risk is the error the case is testing, and the exposure is binary and retroactive.
2. Evaluate the economics of moving the motor to a non-Chinese supplier, and state the decision rule.

Quantify the exposure per unit first. If circumvention is found, duty applies to the customs value - which in this case is not the €360 invoice, see the valuation issue - say €580. At 62.1% that is roughly €360 per bike, or about €4.3 million a year across 12,000 units, plus retroactive recovery and penalties. That is an existential number for the product line, not a cost line.
Quantify the fix. Sourcing the motor from Thailand at €150 instead of €112 adds €38 per bike, or €456,000 a year. Chinese parts then fall to €168 of €513 of parts value, about 33% - comfortably clear of any threshold, with room for further Chinese content later.
Decision rule: compare cost of compliance with probability-weighted exposure. €38 divided by €360 is roughly 10.5%. The switch pays for itself at any probability of an adverse finding above about 10%. Given an open investigation and a parts ratio of 59%, the realistic probability is far above 10%; the switch should be made now, before the audit findings land, so the change can be presented as remediation rather than as a response to being caught.
Sequencing: re-source first, then disclose. Announcing remediation before the audit concludes is materially cheaper than being required to do it.
3. The audit covers customs value. Recalculate the correct value and assess the exposure.
Read the worked answer
The declared value is wrong in a predictable way. Where the buyer supplies materials free of charge to the processor, those materials are dutiable assists and must be added to the price actually paid. The free-issued Korean battery (€150) and EU components (€45) are exactly that. Neither appears in the €360 invoice because the brand bought and shipped them itself.
Rebuild the value: €360 invoiced plus €195 of assists equals €555, plus €25 international freight and insurance, giving a customs value of about €580 per unit against €360 declared. The understatement is €220 per unit, or €2.64 million of value across 12,000 units a year and three years in scope.
Size the consequence. On MFN duty alone the underpayment is modest, but interest and a penalty for an incorrect declaration apply, and - critically - any anti-dumping duty is calculated on the correct value, so the under-declaration multiplies the circumvention exposure rather than reducing it. An undervalued declaration is a poor hedge.
Also test the related-party rule. The transaction value is acceptable for a related-party sale only if it approximates the value between independent parties; a cost-plus invoice from a wholly owned plant should be documented as such, not merely asserted.
Recommendation: make a voluntary prior disclosure, present the corrected valuation method and the motor re-sourcing together as a remediation package, and seek to cap penalties.
