Overview
This HTS classification, 3824.40.20.00, specifically covers prepared additives for cements, mortars, or concretes that consist wholly of inorganic substances. These are chemical preparations designed to enhance the properties of construction materials such as setting time, strength, workability, or durability, without the inclusion of any organic compounds. Examples include inorganic accelerators, retarders, plasticizers, or air-entraining agents.
This category is distinguished from its sibling, 3824.40.10.00, by its complete absence of aromatic or modified aromatic substances. While 3824.40.10.00 encompasses additives containing 5% or more of such organic compounds, 3824.40.20.00 is exclusively for inorganic formulations. The "Other" category, 3824.40.50.00, serves as a residual for any prepared additives not fitting into the more specific inorganic or aromatic-inclusive classifications.
As this is a leaf node, there are no further subcategories. Classification within 3824.40.20.00 is determined by the exclusive presence of inorganic components within the prepared additive intended for use in cement, mortar, or concrete mixtures. The primary function of these additives is to modify the physical or chemical behavior of the construction materials.
