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
Analysis
Heading 2909 of the Harmonized Tariff Schedule covers 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…. It divides into 10 six-digit subheadings and 31 eight-digit tariff lines, with 33 ten-digit statistical suffixes below them.
4 of its 31 lines with a percentage rate are duty-free at the general rate (13%) and 27 are dutiable, from duty-free up to 5.5%. The median line pays 5.5%.
The spread of 5.5 percentage points between the cheapest and dearest lines makes misclassification expensive here. The highest rate, 5.5%, applies to 2909.19.14 (methyl tertiary-butyl ether (MTBE)) and 2909.19.18 (ethers of monohydric alcohols: other).
The largest subheadings are 2909.30 (aromatic ethers and their halogenated…, 8 lines), 2909.49 (other, 6 lines), 2909.50 (ether-phenols, ether-alcohol-phenols and their…, 5 lines) and 2909.19 (other, 4 lines).
By Census's concordance, most of its statistical lines are made by All Other Basic Organic Chemical Manufacturing (325199). Those are the NAICS industries a US producer of these goods would report under.
