1,8-Cineole (Eucalyptol)
1,8-Cineole, also known as eucalyptol, is a bicyclic monoterpenoid ether naturally occurring in eucalyptus oil. Its structure contains an oxygen atom within a saturated ring system, classifying it as a cyclanic ether under tariff item 2909.20.00.
Bisabolol Oxide A
Bisabolol oxide A is an epoxide derivative of alpha-bisabolol, featuring a cyclic ether structure with a terpenoid backbone. It is a chemically defined organic compound used in cosmetic formulations for its anti-inflammatory properties, falling under cycloterpenic ethers.
Cedrol
Cedrol is a sesquiterpene alcohol with a cyclic structure, but it does not contain an ether functional group; it is an alcohol. Therefore, it does not meet the definition of a cyclanic, cyclenic, or cycloterpenic ether and should not be classified under this tariff item.
Cineole Acetate
Cineole acetate is a derivative of 1,8-cineole where the acetate group is attached, but the core structure retains the cyclic ether. As a halogenated, sulphonated, nitrated, or nitrosated derivative of a cyclanic ether, it falls under tariff item 2909.20.00 when the ether functionality is predominant.
Farnesyl Acetate
Farnesyl acetate is an ester of farnesol, a sesquiterpenoid alcohol, and does not contain a cyclic ether structure. It is an acyclic compound, so it does not fall under cyclanic, cyclenic, or cycloterpenic ethers.
Geranyl Acetate
Geranyl acetate is an ester of geraniol, which is an acyclic monoterpenoid alcohol. It does not possess a cyclic ether structure, and therefore does not meet the definition of a cyclanic, cyclenic, or cycloterpenic ether.
Khusilal Oxide
Khusilal oxide is an oxide derivative of khusimol, a sesquiterpenoid alcohol from vetiver oil, forming a cyclic ether structure. As a chemically defined cycloterpenic ether, it falls under tariff item 2909.20.00.
Lavandulyl Acetate
Lavandulyl acetate is an ester of lavandulol, a monoterpenoid alcohol with a cyclic structure, but the compound itself is an acetate ester, not an ether. It does not contain an ether functional group and therefore does not fall under this tariff item.
Limonene Oxide
Limonene oxide is an epoxide derived from limonene, a cyclic monoterpene, containing a three-membered ring with an oxygen atom. This epoxide is a cycloterpenic ether, and as a chemically defined compound, it falls under tariff item 2909.20.00.
Linalool Oxide
Linalool oxide is a furanoid cyclic ether formed by the epoxidation of linalool, featuring a five-membered ring with an oxygen atom. It is a chemically defined cyclanic ether, falling under tariff item 2909.20.00.
Menthofuran
Menthofuran is a cyclic ether with a furan ring, derived from peppermint oil. It is a chemically defined cycloterpenic ether, falling under tariff item 2909.20.00.
Nerolidol Oxide
Nerolidol oxide is an epoxide derivative of nerolidol, a sesquiterpenoid alcohol, forming a cyclic ether structure. As a chemically defined cycloterpenic ether, it falls under tariff item 2909.20.00.
Nootkatone
Nootkatone is a sesquiterpenoid ketone with a cyclic structure, but it does not contain an ether functional group. It is primarily a ketone, and therefore does not fall under cyclanic, cyclenic, or cycloterpenic ethers.
Rose Oxide
Rose oxide is a monoterpenoid cyclic ether with a pyran ring, responsible for the characteristic rose scent in geranium oil. As a chemically defined cyclanic ether, it falls under tariff item 2909.20.00.
Sclareol Oxide
Sclareol oxide is an epoxide derivative of sclareol, a diterpenoid alcohol from clary sage, forming a cyclic ether structure. As a chemically defined cycloterpenic ether, it falls under tariff item 2909.20.00.
