US TSMC probe puts iPhone chips at risk

A US Commerce Department investigation into a possible sanctions breach by TSMC could spell trouble for Apple, as its chip partner could face penalties that ultimately harm production of iPhone and Mac chips.

The United States placed sanctions against Huawei in 2020, blocking the company from accessing components from US companies without approval from the Commerce Department. This also prevented Huawei from using chips made with US-sourced equipment, a restriction that may now cause problems for TSMC, and by extension, Apple.

The US Commerce Department contacted TSMC in early fall, a source of The Information claims, to query if the chip maker was involved making smartphone chips or AI chips for Huawei.

The query seems to be the initial stages of a probe into whether TSMC broke export rules by willingly supplying Huawei with the chips.

It is believed that TSMC was contracted by an intermediary firm that masked Huawei as its client, sources say. TSMC does have to perform due diligence on orders to make sure they are legal, and the probe could determine whether TSMC's checks were sufficient enough to remain legal.

When the sanctions were imposed on Huawei, TSMC said it had stopped taking new orders from the Chinese tech company.

If true, TSMC faces the prospect of penalties, including sanctions of its own. The latter could be more damaging, as it could directly impact the production of chips for clients, which includes Apple.

If TSMC is temporarily blocked from accessing US technology and equipment, this could prevent it from proceeding with production of new lines, or to maintain existing lines. This could put products like Apple's mobile chips in danger of becoming severely limited.

In that case, Apple may have to search for another chip partner in the interim. But, with Apple's size of manufacturing, doing so could be slow and extremely costly.

Such a penalty could have even greater implications. TSMC's facility in Arizona is still being worked on, and a block would cause progress to cease immediately.

The facility's political element may help sway the Commerce Department away from a sanctions penalty. In April, TSMC secured a $6.6 billion Chips Act subsidy from the Commerce Department to continue its chip investments in Arizona.

This is a ludicrous report.

It claims there is a reasonable probability that the US would force US companies to stop buying chips from TSMC because it didn’t do adequate due diligence to detect a shell company that was planning to sell the chips to Huawei. 

Furthermore, the article claims the US would shut down TSMC’s new plant in Arizona. 

Really? 

The US government supposedly would cripple the entire US tech industry over this?

Utter nonsense. 

This is stock manipulation at its finest. Funny how it was issued on the day the world found out Apple sold 20% MORE iPhones in China than last year and the stock soared. 

Please stop contributing to stock manipulation.

Perhaps, but I think there is more to this story than stock manipulation.  I presume that it has already been determined there are 'current' TSMC chips in 'current' Huawei phones. They should not be there of course. The question would be, given the implications for being caught, how could TSMC have been so careless to have allowed this ? The sheer size of the order should have raised suspicion, regardless of how well the buying agent was disguised.

Another example of why bureaucrats can’t run a business whether it’s the EU or the USA commerce department they are totally incompetent. What is also funny is that if you are private company and you become a victim of intellectual property theft (Chinese, Korean, or Israeli) the government throws their hands up and say you’re on your own we can’t do anything good luck file a report and the cooperation from the government seems to be only one way.

The Commerce Department/USDA should be more concerned about the meat crisis in the USA and why a Chinese company owns Smithfield, Farmer John and Nathan‘s hotdogs how does that happen? And to top it off Listeria seems to be everywhere in prepackaged food. With ten people dead and many people sick because of it in the latest outbreak after Boars head.

Tim Apple needs to make some more calls to well placed dictators, and dictators-in-waiting.
