What is HS code for liquid sodium hydroxide?
Use this as a comparison hint, then confirm the final decision with legal notes and country-specific rules.
HS-6 · Subheading
281512
Sodium hydroxide (caustic soda); in aqueous solution (soda lye or liquid soda)
Heading 2815 — Sodium hydroxide (caustic soda); potassium hydroxide (caustic potash) peroxides of sodium or potassium
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-6 281512 when importing or exporting sodium hydroxide in aqueous solution, commonly known as soda lye. For instance, a shipment of 1,000 liters of liquid caustic soda in bulk containers falls under this code.
This code specifically covers sodium hydroxide solutions, which are essential in various industrial processes. In contrast, HS-6 281511 pertains to solid sodium hydroxide, often found in pellet or flake form, used for different applications.
When classifying sodium hydroxide, note that the concentration of the solution can affect its classification. Solutions with varying concentrations might lead you to consider other codes, but HS-6 281512 is for those in liquid form.
If you're dealing with sodium hydroxide solutions, understanding the differences between this code and others like HS-6 281513, which covers peroxides of sodium, is crucial for accurate customs declarations.
