2815.11.00.00 - Solid

This HTS classification, 2815.11.00.00, specifically covers solid forms of sodium hydroxide, commonly known as caustic soda. It encompasses all solid presentations of this chemical compound, such as flakes, pellets, granules, or blocks, which are ready for industrial use or further processing. The key defining characteristic for this category is its physical state – solid – distinguishing it from other forms of sodium hydroxide.

The primary distinction of this category lies in its physical form compared to its sibling, 2815.12.00.00, which covers sodium hydroxide when it is dissolved in water, often referred to as soda lye. Importers and exporters must ensure that the merchandise is accurately identified as either a solid substance or an aqueous solution to apply the correct HTS code. The inherent properties and handling requirements for solid caustic soda differ significantly from its liquid counterpart, necessitating separate classifications.

As this classification is a leaf node, there are no further subcategories. Therefore, the focus remains on the precise identification of solid sodium hydroxide. This includes understanding the various granularities and packaging methods that all fall under this singular HTS code, provided the substance remains in a solid state. This detailed classification ensures that trade statistics accurately reflect the movement of solid chemical commodities.
