HS Code for Nitrogen fertilizer (urea)

Urea is classified under HS code 3102.10. As the most widely used nitrogen fertilizer globally, urea is specifically identified in the first subheading of heading 3102. This code covers urea whether it is in a solid state (such as prills or granules) or in an aqueous solution. Chapter 31, Note 2(A)(viii) explicitly includes urea, whether or not pure, in heading 3102. This is a significant rule because it ensures that urea is classified as a fertilizer even if it meets high chemical purity standards that might otherwise suggest classification in Chapter 29 (Organic Chemicals). The classification is based on the chemical's primary use in global trade as a concentrated nitrogen source. Accurate classification under 3102.10 is vital for applying the correct agricultural tariffs and for monitoring the supply chain of this essential commodity.

Products Included

• Prilled urea for agricultural application
• Granular urea fertilizer
• Urea in aqueous solution (liquid urea)
• Technical grade urea intended for use as fertilizer

Common Misclassification

Urea (3102.10) is frequently misclassified with 3102.80 when it is part of a Urea Ammonium Nitrate (UAN) solution. If the solution is a mixture of urea and ammonium nitrate, 3102.80 is the correct code, whereas 3102.10 is for urea alone. Another error is using 2924.19, which covers acyclic amides and their derivatives; however, the legal notes to Chapter 31 specifically pull urea into the fertilizer category. Furthermore, if urea is packaged in small units (e.g., under 10kg) for retail sale, it may be classified under 3105.10 regardless of its chemical composition.

FAQ

What is the HS code for Nitrogen fertilizer (urea)?

The HS code for urea, whether in solid form or aqueous solution, is 3102.10.

Is liquid urea classified differently than solid urea?

No, both solid prilled/granular urea and urea in aqueous solution are classified under the same HS code, 3102.10.
