Donald Trump’s trade war tariffs send firms to Hong Kong for a little-known legal loophole
- The US ‘first sale’ rule allows duties to be levied only on the initial sale from the manufacturer to the initial wholesaler
- The rule is legal in the US but requires voluminous paperwork

There were a few worried faces on the 23rd floor of a skyscraper in the business hub of Hong Kong’s Taikoo Place last Wednesday afternoon.
One of the most worried belonged to a supply chain manager for a Canadian technology company which manufactures the bulk of its products in China for export to North America.
A few years ago, in an effort to combat rising labour costs in the southern mainland province of Guangdong, his company shifted some of its production to Laos, only to find that the quality and support was nowhere near the level in South China.
“We wanted to move back to China,” he said. “Yes it is more expensive, but the support is much better.
“But then they started talking about tariffs.”

The company is now stuck with sub-par production facilities in Laos. However, since the trade war began last July, anything produced in its plants in China is subject to a 10 per cent tariff when exported to the US. In March, if there is no trade agreement, this is due to increase to 25 per cent.
