Analysis
HTS 2815.11.00 covers sodium hydroxide (Caustic soda): solid under heading 2815 (sodium hydroxide (Caustic soda); potassium hydroxide (Caustic potash); peroxides of…).
This line's footnotes point to one additional provision in Chapter 99: 9903.90.08 (measures on products of Russia). Chapter 99 duties are added on top of the general rate for goods of the countries they name, and they change more often than the rest of the schedule, so check the current CBP guidance before you rely on a total.
Within this group the rate runs from duty-free to 3.7%. Compared with 2815.30.00 (peroxides of sodium or potassium), which pays 3.7%, a misclassification either way moves the duty by 3.7 percentage points.
The normal trade relations rate here is zero, shared by about 29% of the 274 tariff lines in chapter 28, a useful check when a neighbouring dutiable line is a candidate. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.
The other lines in the same group are 2815.12.00 (in aqueous solution (Soda lye or liquid soda), duty-free), 2815.20.00 (potassium hydroxide (Caustic potash), duty-free) and 2815.30.00 (peroxides of sodium or potassium, 3.7%).
