Is it correct to say "electronics products" or "electronic products"?
There's a very, very slight difference in meaning: electronic refers, basically, to what's inside; essentially anything that uses electricity (rather than, say, steam), and is controlled by electrical signalling/switching rather than mechanical, is "electronic". Electronics, on the other hand, refers to a class of products, generally intended for use by the public rather than by industry, and often for entertainment rather than utility. The Consumer Electronics Association, which puts on the annual Consumer Electronics Show (better known as CES), is largely responsible for establishing and maintaining the distinction between the two, I think.
A CNC laser cutter is an electronic product; an iPod is an electronics product.
