2904.10
Derivatives containing only sulfo groups, their salts and ethyl esters
Analysis
Subheading 2904.10 covers derivatives containing only sulfo groups, their salts and ethyl esters, within heading 2904. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 7 US tariff lines below it are national.
None of its 7 lines is duty-free at the general rate. Rates run from 4.2% to 5.5% with a median of 5.5%, so the line you choose sets the duty.
The US splits it as follows: 2904.10.04 for 2-Anthracenesulfonic acid (5.5%), 2904.10.08 for benzenesulfonyl chloride (5.5%), 2904.10.10 for m-Benzenedisulfonic acid, sodium salt; 1,5-Naphthalenedisulfonic… (5.5%), 2904.10.15 for mixtures of 1,3,6-naphthalenetrisulfonic acid and… (5.5%), 2904.10.32 for products described in additional U.S. note 3 to section VI (5.5%), 2904.10.37 for aromatic: other (5.5%) and 2904.10.50 for other: other (4.2%).
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.
