Dear Mr. Caffrey: In your letter dated December 2, 1999, you requested a tariff classification ruling for Media Grade Long R3 IGF-1 which you have stated is a non-sterile synthetic derivative of the hormone insulin and is a recombinant of naturally occurring insulin. It is the opinion of this office that this product is not used as a hormone (i.e., to inhibit or stimulate the functioning of particular organs). Rather, it is used in vitro as a growth stimulant in tissue culture.
