Dehydromirex Isomer Mixture
Dehydromirex is a mixture of isomers of Mirex (ISO), a fully chlorinated cyclopentadiene derivative. Under Chapter 29 Note 1(b), mixtures of two or more isomers of the same organic compound are classified in the same heading as the chemically defined compound, provided they are not excluded by other provisions. This product is used in toxicological studies as a surrogate for Mirex photodegradation products.
Mirex Analytical Reference Standard
Mirex analytical reference standard is a certified reference material of Mirex (ISO), a chlorinated cyclopentadiene derivative. It is a separate chemically defined compound, classified under Chapter 29 as a halogenated derivative of cyclanic hydrocarbons. Supplied in amber vials for use in GC-MS calibration, it meets the criteria of Chapter Note 1(a).
Mirex Stabilized for Transport
Mirex stabilized for transport contains Mirex (ISO) with an added stabilizer to prevent degradation during shipping. Under Chapter 29 Note 1(f), products with a stabilizer necessary for preservation or transport remain classified in the same heading as the base compound. The stabilizer does not alter the product's specific use, so it falls under this tariff item.
