Reading the Treasury Dept proposed rules, I got the impression that:Tesla can't know anything until April 18th (or thereabouts). "Anticipated to be reduced" is safer term to use in the face of that uncertainty rather than "will be eliminated".
"Hey, I only bought a car now because you said the credit would be $0, instead it's $3,750. Rabble!"
The options I see for half credit is if sufficient critical minerals are imported to CATL and they make cells/ modules which are then shipped to Tesla. Or CATL ships cells to Tesla and they assemble the modules. However, I don't think that is how it works currently.
1) $3750 credit comes from the battery "critical minerals," of which a percentage must be from US or "free trade countries" (50% for 2023). Those countries were listed, and included Japan which has a free trade agreement only for "battery minerals" with the US. The minerals must be either mined or processed in one of these countries.
2) $3750 credit comes from the value of "battery components" produced in North America (must be 50% for 2023). The only components that must meet this test are the cathode, anode, current collector foils, separator, and electrolyte. Cell cans or pouches, and all other battery pack components, do not need to meet this requirement.
