I need a list of all companies that provide taggants that can be
applied to merchandise labels (brand protection) and security
documents (stamps, passports, currency, and so on).  Include the
product/s they offer.

An example of what I'm looking for is Superior Microfibers, which was
bought by Cabot Industries.

Websites/contact name and other contact information would be appreciated.

Taggants may be fibre-based (glass, ceramic), chemical (DNA, nano
particles), and magnetic, from what I understand.

Just a good list of taggant suppliers - no need to get all of them.

Questions which require a list of "all" of something sometimes go
unanswered. It is virtually impossible for a Researcher to guarantee
that all of anything has been found. You're more likely to get a good
answer by asking for a finite number of companies.

Good point.

Revise the request to be "a good number of"...I don't need every last
one in existence, just a fairly comprehensive list based on best
effort.
