My guess is Menzerna USA does not import this skew into North America and the likely reason is there's already enough medium cut polishes in the current offering.
Here's what the German Menzerna says about this product.
Also new is the universal polish Intensive Polish 2100. With a gloss of usual high quality this polish removes grit of up to 2.500 more quickly and time saving. Rapidity, applicability on all original and refinish coatings, process reliability under all conditions and a superior price-performance ratio, make the IP 2100 an ideal polish for aftermarket user.
My guess is it works really well like all Menzerna products.
