Your engine was made, your transmission was made, your frame was made, in either Windsor Ontario Canada, or Monclova/Monterrey, Nuevo Leon Mexico. Brake pads, power steering components, even the glass is made in Mexico. NAFTA. Mexican part shipped to Canada is considered a Canadian part. Cylinder heads cast at the Sicartsa steel mill in Monclova ending up in Portland Maine, are Made in USA.
Oh the game playing doesn't stop there. Digital control models made in Indonesia, programmed in India are shipped to Mexico and then the modules are sub assembled thus covered under NAFTA then shipped to the USA. Made in Djkarta, with adhesive label on harness "Made in Mexico. Delphi and Motorcraft use nothing but made in China starters and alternators. Got a Denso alternator or starter? Product of Guondong prefecture China.
Customer reviews are my sole source of pre purchase confidence and arm twisting. 567 reviews and 4.75 stars is a good indication the product is not junk.
As pointed out in an earlier response, Korean-Japanese leadership run the top of the heap factories. Americans employ Koreans and Japanese as interfaces. USA management is concerned with bottom-line quality, just in time logistics, and to lubricate the bamboo gears of the titanic mechanism as needed. US purchases are keeping 800,000,000 chinese employed, so Beijing listens to pontifications handed down the Americans at the factories. Dollar diplomacy in action. But it's the Japanese and Koreans doing the engineering and nuts and bolts physical administration of the factory's white shirt and tie crowd. Chinese white collar workers have 2 masters: The buyer and Beijing. The Government Central Committee has one master - the fear of three quarters of a billion workers carrying pitchforks and torches with growling stomachs.
BTW the module for that TDS meter is more than likely Chinese. Poland produces excellent bearings and the Czech Republic make some of the finest consumer lathes and mills on the face of the earth. Tooling, too.
Meanwhile on this half of the earth, LTH battery S.A. de C.V. keeps spitting out Optima batteries.
Now do you -really- believe the department of Commerce demands certificates of origin for NAFTA parts? If you do, then you'll believe that crude oil actually is shipped to the USA from the far East. Or that the USA needs to import one microgram of crude oil from beyond its borders. The key word is -need-.
It's a massive, pea under the walnut shells con game to reduce taxes.
So I have to concern myself with that purchase of 100 555 timer modules on eBay that cost me one single US cent. Damned shipping cost two dollars twenty nine cents. Or the 117 ampere MOSFET transistors that cost sixteen cents each, solid state relays four dollars (25 amp DC relays) free shipping. The star heat sinks, next month a shipment of 11,000 1/4 and half watt resistors, thirteen dollars delivered. One ohm to 4 megohm. One percent resistors. Then the optocouplers, PC boards. And finally LED chips.
I ran my company for 22 years. The "secret" to success is not what you sell a product for, it's what you buy it for. And excessive warranties are death to a company's solvency.
We'll see tomorrow how much of a discount Hero Long March Factory no 221 is going to give me on a sizable purchase of LED driver modules. Pure Chinese product. Am I worried about quality? nah! The most they can do is blow-up and take off an arm or a leg - I got a spare of each.
