200,000 lbs [90 tonnes] or less), says Swain. Advan- tages, however, are that they are highly covert and difficult to replicate. Microtrace says that its Microtaggant Identification
Particles (MIP) are the original taggant technology (developed by 3M) and the origin of the term “taggant.” Microtaggant particles range in size from 20-1,200 microns and contain a unique numeric code sequence represented by a multiple coloured layer particle. Microtrace also supplies additional taggant technolo- gies that can be incorporated into each MIP as a multilevel solution. For example, up-converting phosphors that can be detected with a handheld laser-pen and UV light can be added to the particle. The company supplies Microtaggants in various forms, including masterbatches and as an additive for incorporating into a masterbatch. Microtrace also offers Molecular Taggants, intro-
duced in 2012, for use in authenticating and quantifying the dilution of bulk materials. Because they are used at a trace level, it is nearly impossible for a counterfeiter to detect and virtually impossible to replicate, says the company. The primary use of Molecular Taggants is to

measured using a portable spectrometer-based optical
