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, 2929.90.50.40, encompasses specific organophosphorus compounds characterized by their phosphoramidofluoridate structure. These chemicals feature an O-alkyl group, where the alkyl chain is either hydrogen or contains up to ten carbon atoms (including cycloalkyl groups), and an N-(dialkyl amino)alkylidene group with a similar carbon chain limitation. The category also includes corresponding alkylated or protonated salts of these phosphoramidofluoridates. These substances are typically used as intermediates in the synthesis of more complex organic molecules, often within the agricultural or pharmaceutical industries, and their classification hinges on the precise arrangement of functional groups and the nature of the alkyl substituents.

It is important to distinguish this category from its siblings. Unlike the phosphoramidic dihalides (2929.90.50.10), these compounds contain a fluorine atom attached to the phosphorus atom and an amino group instead of two halide groups. Furthermore, they differ from the phosphonamidic fluorides (2929.90.50.30) by having a phosphoramidate backbone rather than a phosphonamidate backbone, signifying a different arrangement of oxygen, nitrogen, and phosphorus atoms. The phosphoramidates (2929.90.50.20) also have a different structure, lacking the characteristic fluorine atom and the specific N-(dialkyl amino)alkylidene substituent that defines this particular code.

As this HTS code represents a leaf node, there are no further subcategories. Classification within 2929.90.50.40 is definitive once the chemical structure meets the specified criteria for O-alkyl, N-(dialkyl amino)alkylidene, and phosphoramidofluoridate functional groups, along with the defined alkyl chain lengths and the inclusion of any alkylated or protonated salts. Importers and exporters should meticulously verify the chemical composition against the description to ensure accurate classification.
