This TPMS valve I took a photo is from MOBIS, but it is not made in Korea. It’s imported.

As you see, it’s by Schrader Electronics.

But!

52933C1100

Made in China.

I think because it’s the imported part, I cannot receive many when I order them over 50pcs. I received only 2-5 pcs per 1 order.

I don’t have information about Schrader, but it seems they are famous manufacturer of TPMS sensors as I see their web site : http://www.schraderinternational.com/Products/Product-Folder/NA-TPMS-OEM-Sensorsed61.html?sc_lang=en-US-NA

I guess (1) Hyndai group has lack of technology for producing TPMS sensors
or (2) it’s cheaper to import TPMS than to produce.
( Provably reason may be (2) :p)

Not surprised that this part is made in China but the maker is in US.
(I though it’s a German company but it’s not) as “Nike” clothes and shoes are manufactured in China or Vietnam, not USA.

As you see, it’s difficult to have all kinds of auto parts made in Korea. Even Hyundai and GM are importing some parts from overseas. And no one can blame about it, right?
