What is the percentage of major supply coming from outside China 
 -- Analyst
OK. Great. And then my second question, I think the big fund, the National IC Industry Investment Fund is about to kick off its big second phase of capital investment. It -- to the local chip guys in China. Is that supportive of your solid outlook for this year or could there actually be upside to your estimates as that begins to flow in the marketplace?
David Wang -- Chief Executive Officer
Yes. Actually, as mentioned, I feel [Inaudible] is really boosting for their -- actually, their fiber building and fiber expansion plan. As we mentioned a couple times, China customer and they're really under multi-year expansion plan, either you called it YMTC or Huali Huahong Group and all the SMIC and other -- also other new DRAM customers too. So they have a multiyear expansion plan, and obviously this is the new founding injection into their -- our customer side and what -- that may be improving our visibility and give us more of an opportunity.
Beyond that, it's also [Inaudible], I should say, power device fab is also gaining the support in some -- those funds. So we see that expansion of new fab will give us a new opportunity too.

Thank you. Next question comes from the Patrick Ho with Stifel. Please go ahead.
Patrick Ho -- Stifel Financial Corp. -- Analyst
Thank you very much, and congratulations, and glad to hear everyone well. Maybe first off in terms of the supply chain. You mentioned on the prepared remarks that it's fine and everything is going well. Can you discuss any potential disruptions that you did have over the last few months, and whether that's part of the reason why you're pushing out some of the system deliveries into the second and third quarters.
And what gives you confidence that it's now resolved where you don't have to use, I guess, second or third source suppliers?
David Wang -- Chief Executive Officer
OK. Great. Actually, just for the supply chain EBITDA line first, at this moment, I should say probably our major supply and probably 70% come from outside China. In that pouring, I call the import from China in which probably most of them from Japan and some are also from Korea.
And we do have about less than probably 10% from U.S. and 10% from Europe. That's our supply chain distribution. In the last two months, three months, we didn't see any supply chain delay, right? Until that time obviously China got to suffer.
We do have seen some of our machine shop and gather people not on time return to the job. But at this moment, all our supply in China for machine shop have been on the line already. So as I see that is our major tool pushing from the Q1 to Q2 is obviously you see that is -- in the Wuhan, our customer YMTC, they do have manpower or they subcontract. They cannot go through the Wuhan restrictions, so that's why some tool we suppose ship to the YMTC in the Q1 was pushed to the Q2.
That's the major reason, right? So, obviously, we will watch carefully for our supply chain now since the coronavirus has kind of spread out and -- however, we're lucky to see Japan and Korea that is stable and hopefully in a few months, we are going to see U.S. and Europe get stable. So we are, so far, cautious watching. We feel probably OK for a real long -- I call it, for imported components at this moment.

Great. That's helpful. And maybe a question for you, Mark, in terms of capex for this year, especially as you get the third facility signed on and begin the process there, can give a little bit of color on how much you think potentially you're going to invest in capex for 2020?
Mark McKechnie -- Chief Financial Officer
Yes. Hey, Patrick, thanks for the question. So the capex for 2020 is just normal run rate operations, $2 million to $5 million is what we're looking at, adding a second floor to production at our second factory and some other upgrades. So that's kind of our normal run rate.
We did talk about the land for our new production in R&D site out there in Lingang. So if we reach agreement on that, we could see putting some money down for t
