HS Code 29049050: Nonaromatic sulfonated, nitrated or nitrosated derivatives of hydrocarbons nesoi

The HS Code 29049050 refers to nonaromatic sulfonated, nitrated or nitrosated derivatives of hydrocarbons not elsewhere specified or included. This code helps in identifying and classifying these specific derivatives for international trade purposes. Let's dive deeper into the details of this HS code and understand its significance.

Product Description

The product described by HS Code 29049050 includes derivatives of hydrocarbons that have undergone the process of sulfonation, nitration, or nitrosation. These derivatives are nonaromatic in nature, meaning they do not contain any aromatic compounds.


Sulfonation is a chemical process that involves the addition of a sulfonic acid group (-SO3H) to a molecule. Nitration, on the other hand, refers to the introduction of a nitro group (-NO2) into a molecule. Nitrosation is the process of adding a nitroso group (-NO) to a compound.


These modifications in the hydrocarbon derivatives can alter their properties and make them suitable for various industrial applications.

Bound / MFN Duty Rate

The bound or Most Favored Nation (MFN) duty rate for HS Code 29049050 is 3.7%. The MFN duty rate is the standard tariff rate that applies to imports regardless of the country of origin. It ensures that every country treats all its trading partners equally by applying the same duty rate for the same goods or services.


Trade barriers can include tariffs, quotas, or other restrictions imposed by a country to protect its domestic industries. When a country lowers its trade barriers or opens up its market, it has to do so for all its trading partners, ensuring fair and non-discriminatory trade practices.

Quantity Unit

The quantity unit for HS Code 29049050 is kilograms (KG). This unit helps in determining the weight or quantity of the nonaromatic sulfonated, nitrated, or nitrosated hydrocarbon derivatives being imported or exported.

Special Tariff Preference Programs

Several special tariff preference programs are available for imports classified under HS Code 29049050. These programs provide preferential treatment in terms of duty rates or duty-free treatment for certain trading partners. Here are some of the special tariff preference programs applicable to this HS code:

Importing US States and Exporting US States

The HS Code 29049050 is applicable to trade between the United States and various countries. The importing US states can include any state within the United States that receives imports of nonaromatic sulfonated, nitrated, or nitrosated hydrocarbon derivatives classified under this HS code.


The exporting US states, on the other hand, can include any state within the United States that exports such derivatives to other countries.

HS Code 29049050 plays a crucial role in identifying and classifying nonaromatic sulfonated, nitrated, or nitrosated derivatives of hydrocarbons. It helps in facilitating international trade by providing a standardized system for customs and trade authorities to track and regulate the import and export of these specific products. The special tariff preference programs further enhance trade opportunities and promote economic cooperation between countries.
