Silicon Valley shivers down on Wednesday comfort if President Donald Trump’s Tarff Bananza Includes an exemption for semiconductors, which, at least for today, cannot be subject to higher import duties. But only three days ago, some US tech companies may find that the loophole actually creates a lot of problems than it can be solved. After announcing tariffs, the White House Published a list of the products saying unaffected, and it does not include many types of items associated with the chip.

That means a small number of American manufacturers that can keep the chips fixes without having to cause import costs. The majority of semiconductors coming to the US are currently wrapped in non-free products, such as graphics processing units (GPU) and training servers artificial intelligence models. And manufacturing facilities used by home companies to produce US chips are also not saved.

“If you are a primary chip producer who makes a big invest in the US, a hundred billion dollars can buy you more years,” says Martin Chorzenite in international economies.

The US Kommerce Department does not respond to a request for commentary.

Stacy Rasgon, a senior analyst covering the semiconductors of Bernstein research, says narrow exception for chipers of adverse effects on the negative impact on industry. Given most of the semiconductors arrive at US boundaries wrapped in servers, smartphones, and other products, “as Rasgon’s total tariffs,” as the tarparks of a 40 percent of the total imported rates of duty.

Rasgon has been designed that the semiconductor industry depends on other imports and the US economic health, from many classes of consumer products, from carcasses made by cars in the refrigerator. “They are macros-expospose,” he said.

To find out what items are available at tariffs, the Trump administration depends on a complex system called the million of tariff (HTS) with different import categories. The White House document only lists a narrow group of HTS codes in the semiconductor field said from new tariffs.

For example, the GPUs are usually sorted as 8473.30 or 8542.31 of NSTS Wei, a supply analyst to consult a consultation with Eurasia company. But Trump’s waiver applied only to more advanced GPUs in the late 8542.31 category. It also does not cover other codes for related types of computer hardware. NVIDIA DGVIA systems, a pre-configured server with built GPUs designed for computing tasks, coded as 8471.50, according to company’s websitewhich means it is likely not except for tariffs.

The line between these differences is sometimes blamed. In 2020, for example, an import of two NVIVIA GPU models asked us the authorities to explain what category they considered to fall. After viewing this item, US Customs and Border Protection determined that The two GPUs belong to the 8473.30 category, which will not be free from tariffs.
