9902.04.12 - Copper(2+) sodium 2,2',2'',2'''-(1,2-ethanediyldinitrilo)tetraacetate (1:2:1) (CAS No. 14025-15-1) (provided for in subheading 2922.49.80)

HTS code 9902.04.12 specifically classifies Copper(2+) sodium 2,2',2'',2''-(1,2-ethanediyldinitrilo)tetraacetate (1:2:1), identified by CAS Number 14025-15-1. This entry falls under Chapter 99 of the Harmonized Tariff Schedule, which is reserved for temporary legislation and modifications, including those proclaimed pursuant to trade agreements or section 22 of the Agricultural Adjustment Act. The parenthetical note indicates that the classification of this specific chemical compound is typically found under subheading 2922.49.80 in the permanent sections of the HTS.

This temporary classification within Chapter 99 distinguishes it from the primary HTS classifications found in Chapters 1 through 97. While siblings at the root level like live animals (e.g., HTS 0101, 0102) represent entirely different categories of goods, this code represents a specific chemical substance that is subject to special import provisions rather than its standard commodity classification. The purpose of classifying this compound under Chapter 99 is to implement specific trade policy or regulatory measures not reflected in the general HTS structure.

As this is a leaf node, there are no subcategories to explore. The classification is definitive for the specified chemical compound under the stated temporary legislation. Its presence here signifies that imports of this substance are subject to particular restrictions, duties, or reporting requirements that are not applicable to its standard classification under Chapter 29. Users should consult the specific trade agreements or legal proclamations referenced by Chapter 99 to understand the full scope and implications of this classification.
