About heading 2909
Ethers, ether-alcohols, ether-phenols, ether-alcohol- phenols, alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, ketone peroxides (whether or not chemically defined), and their halogenated, sulfonated, nitrated or nitrosated derivatives
Heading 2909 covers ethers, ether-alcohols, ether-phenols, ether-alcohol-phenols, alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, and ketone peroxides, plus their halogenated, sulfonated, nitrated or nitrosated derivatives. The heading splits first by chemical type: acyclic ethers in 2909.11 through 2909.19, cyclic ethers in 2909.20, aromatic ethers in 2909.30, ether-alcohols in 2909.41 through 2909.49, ether-phenols in 2909.50, and peroxides in 2909.60. Within each group the lines turn on structure and end use, such as monohydric versus polyhydric alcohol ethers, or odoriferous and flavoring compounds versus pesticides.
