About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS category, 2904.35.00.00, specifically covers salts of perfluorooctane sulfonic acid that are not explicitly listed under more specific sibling subheadings. This means it acts as a residual category for any perfluorooctane sulfonic acid salts not falling under the ammonium, lithium, or potassium classifications. Examples would include salts formed with other metal cations or organic cations.

The distinction from its sibling categories is crucial for accurate classification. HTS 2904.31.00.00 is for the free acid itself, while 2904.32.00.00, 2904.33.00.00, and 2904.34.00.00 are dedicated to the ammonium, lithium, and potassium salts, respectively. This category (2904.35.00.00) captures all other salts of perfluorooctane sulfonic acid, ensuring that diverse forms of this compound are correctly accounted for within the tariff schedule.

As this is a leaf node, there are no further subcategories under 2904.35.00.00. Therefore, the classification decision relies entirely on identifying whether a given perfluorooctane sulfonic acid salt is indeed a salt and does not match the specific cation profiles of the preceding sibling entries. Classification will typically be based on the chemical identity of the cation present in the salt.
