"Origin rules and transshipment: why swapping the label does not count"

Moving the last process step to a third country and swapping the certificate of origin was once seen as a way to save money. Both ends of that route are now raising their barriers, for the same reason: substantial transformation.

Origin is not "the last place it shipped from"

In many procurement processes, origin is simplified to "which country the goods shipped from". But origin rules do not look at the last transit port - they look at which country the goods underwent substantial transformation in.

A batch manufactured entirely or mostly in China, with only the packaging changed or a label applied, does not become Vietnamese origin just because the final port of loading is written as Vietnam. That is exactly where the transshipment route breaks down: it relies not on looking the part, but on real processing. Swapping a label changes only the last formality; it cannot change where all the earlier steps happened.

The bar in Southeast Asia is rising

According to publicly released information, since April 2025 Vietnam's customs has stopped more than 2,000 batches of Chinese goods falsely marked "Made in Vietnam"; for goods with a high Chinese content it plans a punitive tariff of 40 percent, and has repeatedly stressed the "substantial transformation" standard.

That standard is not unique to Vietnam. It is written into the origin rules of most trade agreements: for a product to change nationality, processing must reach a certain depth - simple assembly, repackaging and labelling are usually not enough.

So whether "move the last step to a third country" holds up depends on the step itself, not on whether you have a local warehouse.

Regulators follow the trail upstream

Avoidance is not only watched at the destination country's ports. US Customs and Border Protection has actively pursued cases through EAPA: companies routed Chinese-made oil country tubular goods through Thailand while concealing the true origin, and were ultimately found to be evading.

What characterises these investigations is that they work backwards along the document chain: bills of lading, invoices, certificates of origin, processing records and fund flows are compared together. If any link does not match the claim of "produced in a third country", the whole claim collapses.

The consequences land on the importer

Once traced, it is the importer - not the intermediary who helped swap the label - that bears the back duties, fines and even criminal liability. That is why the "savings" from transshipment often exist only on paper.

Reducing the risk is not complicated, but it has to be done before ordering: require the supplier to state the actual place of production and where the main processes are completed, and write the origin representation and burden of proof into the contract. Whoever writes these into the contract usually avoids the most expensive lesson.
