HS Code for Potassium

Pure elemental potassium is classified under HS code 2805.19. This classification is found within Chapter 28 (Inorganic chemicals) and Heading 2805, which covers alkali or alkaline-earth metals, rare-earth metals, scandium, and yttrium. Potassium is an alkali metal, and since the subheadings 2805.11 and 2805.12 are specifically allocated to sodium and calcium respectively, potassium falls into the 'other' category of 2805.19. Classification as a pure metal requires that the substance not be alloyed or compounded with other elements in a way that changes its basic chemical identity. Potassium is highly reactive and is usually shipped immersed in oil or in vacuum-sealed containers to prevent oxidation. This code is strictly for the metallic element and does not include potassium salts, oxides, or hydroxides, which are classified elsewhere in Chapter 28 or Chapter 31.

Products Included

• Elemental potassium metal
• Potassium ingots
• Potassium sticks or lumps (stored in mineral oil)
• High-purity potassium for laboratory use

Common Misclassification

Potassium metal is often confused with its various compounds. Potassium hydroxide (caustic potash) is 2815.20, and potassium carbonates are 2836.40. It is also vital not to confuse it with potassium fertilizers under 3104. In many trade contexts, the word 'potassium' is used loosely to refer to potassium salts; however, for customs purposes, 2805.19 only applies to the silver-white alkali metal in its elemental state.
