HS Code for Potassium chloride

Potassium chloride is classified under HS code 2827.39 when it is a separate chemically defined compound not intended for use as a fertilizer. This code is found in Chapter 28, which covers inorganic chemicals. Heading 2827 includes chlorides, chloride oxides, and chloride hydroxides. The subheading 2827.39 is a residual category for "other" chlorides not specifically named in the preceding subheadings (like ammonium, calcium, or magnesium chlorides). Potassium chloride is used in various industries, including food processing (as a salt substitute), pharmaceuticals (for potassium supplements), and industrial applications like oil well drilling. The classification under 2827.39 is strictly for high-purity or technical-grade potassium chloride that does not meet the criteria for Chapter 31 (Fertilizers). According to Note 1 to Chapter 28, the product must be a separate chemically defined compound to remain in this chapter.

Products Included

• Pharmaceutical grade potassium chloride
• Food grade potassium chloride (E508)
• Analytical reagent (AR) grade potassium chloride
• Industrial grade potassium chloride for non-fertilizer use

Common Misclassification

The most significant area of confusion for potassium chloride is HS code 3104.20. Chapter 31 covers fertilizers, and 3104.20 specifically covers potassium chloride (muriate of potash) intended for use as fertilizer or imported in bulk for that purpose. If the potassium chloride is in a form or purity typically used for agriculture, it must be classified under 3104.20 regardless of its actual end-use. Another misclassification is 2501.00, which is for sodium chloride (common salt). While both are halides, the HS system distinguishes between alkali metal salts based on the specific cation.

FAQ

What is the HS code for Potassium chloride?

For chemical, pharmaceutical, or food use, the HS code is 2827.39. For agricultural fertilizer use, the HS code is 3104.20.

How do I distinguish between 2827.39 and 3104.20?

Classification depends on the purity and the intended trade application. Generally, if the product is highly refined (e.g., USP or Food Grade), it belongs in 2827.39. If it is crude or technical grade sold for soil application, it belongs in 3104.20.
