Made in Thailand should mean exactly that. Thailand’s government is planning to crack down on companies exporting goods assembled in the Kingdom using mainly foreign parts as a way of dodging tariffs, quotas and other trade regulations, a deceptive practice known as ‘false origin’ export labeling.

Officials said that more products will be added to an existing watchlist of 49 goods cited for false claims of origin. The practice is among the concerns expressed by American authorities to their Thai counterparts, according to the Ministry of Commerce.

The Ministry has identified nine more groups of products it deems as having a high risk of circumventing the rule of origin. Foreign companies using Thailand as a base for re-exports to the U.S. is a problem that has grown over the years, said the Department of Foreign Trade.

Among the products Thai authorities believe bear watching are steel, copper wire and aluminum. But others are also prone to the deception. They said that foreign-owned firms are the main culprits in false-origin schemes.

The Bangkok Post said “the bid to deter companies from misusing the local content rule will be cheered by Thai companies, who have long been complaining of dumping” of cheaply made goods from foreign sources in recent years.

The paper said that a survey of Thai companies’ chief executives showed that almost 71 percent of the respondents were worried about cheap goods flooding Thai markets, leading to lower use of production facilities and more factory closures.

By bringing in foreign-made components for manufacturing, Thai parts suppliers lose business. Meanwhile, the offending companies export products labeled as ‘Made in Thailand’ but their content isn’t truly Thai made.
