Yes.

Ironically because US companies fear the impacts of these again comeing higher tariffs, they are stockpileing stuff before they go into effect.

What does that mean for china?
Well their selling more than ever to the US.

Greed of the american companies so far, has basically undermined any and all effects this would have on china.
And because these american companies stockpiled so much, it wont show a effect on america goods, or china's production until a year or more down the road.

"So far, the trade war has not had any significant impact on China’s trade and broad economy. Manufacturers’ front-loading may be partly responsible."

"China’s exports rose 14.5 per cent in September from a year earlier, accelerating from a 9.8 per cent rise in August. Meanwhile, its trade surplus with the US, its biggest export market, widened to a record US$34 billion last month."

"If this does not work, its US clients will have to raise sales prices. Some of its US clients have asked Seagull to “shoulder part of the extra costs”,
but the company said it was trying to avoid that."

^ if these tariffs last (a year more), then it ll finally start effecting prices of goods in the US.

Non so far, their China's export rose 14,5% this year on year, from last september.

American companies fear these constant riseing price Trump will put on imports, and are trying to stockpile their way around the issue (putting it off for as long as possible).  China has responded to this demand and thus has sold more than ever to the US.

Once the Stockpile amount runs out.... what happends?

Well american companies keep buying from china.
How does that work out if prices go up? well the american consumer will have to pay more for things then.

They don't, Trump's hope is that American companies can grow to become more competitive against China in lower value products under his policy of protectionism much like China did when they were developing their own industries ...

America is failing to be the leader in the semiconductor foundry industry but they luckily still have leadership in aerospace technology and medical research. American dominance in it's products is good for the western world since they share many common geopolitical interests. Do you actually want to contemplate the idea of giving China a monopoly so that our own industries will wither away in death ? 

Are you comfortable with the idea that we would have to buy high end and extremely proprietary technology like crummy state backed corporations from China ? At least America is willing to comply with many European's nation of price controls on drugs but when China comes up with far better drug candidates which will keep as many secrets under wraps, I wonder if they're as willing to participate ...  

It'll be great to see China rise, at the expense of the naive liberal western states who have no idea that their power is slowly fading away because they have no economic might to back them up ... 

Are they? I feel that is an industry where the U.S. can obliterate China.

America holds almost complete dominance on foundry equipment with Lam Research and Applied Materials and their export ban against Fujian Jinhua will probably set back Chinese DRAM ambitions a decade. Not to mention Chinese reliance in American semiconductors brought ZTE to its knees and it was only saved by surprising mercy from Trump.

For the most part the US is already ahead of China in semiconductors. What China wants most is to obtain further independence in their semiconductor foundry industry and the semiconductor foundry industry is more than just foundry equipment for DRAM ... 

America does not have dominance in the semiconductor foundry industry anymore. Intel fell off the wayside over the years in terms of cutting edge logic fabrication, the countries which lead are now Taiwan with TSMC and South Korea with Samsung. Given the fact that the former shares a language with China, I imagine in the extended future it won't be long before China sees more success in logic fabrication by poaching the engineers behind TSMC's talent because lord knows that Taiwan can't compete in the money race any longer and China doesn't have to worry about a blockade either in that case since it's ASML who dominates in the logic foundry equipment department which is based in the Netherlands. Yangtze Memory Technologies Corporation will soon enter the flash memory technology fabrication market with the clear leader being Samsung ... 

You think that an export ban will somehow stop Fujian Jinhua from entering the DRAM fabrication market when the state backing the enterprise has a $22B war chest ? If China are desperate then they'll probably just buy SK Hynix from the SK Group which is farther ahead than the best the US already has to offer in DRAM fabrication which is Micron Technology ... 

America can't hold China in it's shackles for high end technology any longer. If China does ever become competitive in aerospace technology or pharmaceutical research there's possibly no turning back when the world is headed upside down ... 

The US already lost dominance in the semiconductor foundry industry to other countries in east asia but it'll get really ugly when China starts making inroads in passenger aircraft's or drug candidates ... 

Nope, not at all.
