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 classification, 8421.99.01.80, covers "Other" parts for machinery and apparatus for filtering or purifying liquids or gases, or for centrifuges. This broad category encompasses components that are not specifically enumerated in other subheadings within 8421.99.01. Examples might include specialized fittings, seals, or structural elements that are integral to the functioning of filtering, purifying, or centrifugal machinery but do not fall into more defined categories. The key is that these parts must be designed for use with the machinery described in heading 84.21.

Crucially, this "Other" category serves as a residual provision. It is distinguished from its sibling category, 8421.99.01.40, which specifically covers parts for machinery and apparatus used for filtering or purifying water. Therefore, if a part is intended for the purification of water, it would be classified under 8421.99.01.40. Only those parts for filtering or purifying liquids or gases, or for centrifuges, that do not meet the specific criteria of any other subheading under 8421.99.01 are to be classified here.

As this is a leaf node, there are no further subdivisions. Classification within 8421.99.01.80 relies on a process of elimination, ensuring that the part in question is indeed for the relevant machinery under heading 84.21 and does not fit into any more specific classification at this or higher levels. The determination often hinges on the intended use and the specific design characteristics of the part in relation to the overall apparatus.
