HS Code for Malonylurea

Malonylurea, commonly known as barbituric acid, is classified under HS code 2933.52. This classification falls within Chapter 29, which covers organic chemicals. Specifically, heading 2933 is reserved for heterocyclic compounds with nitrogen hetero-atom(s) only. Malonylurea is a pyrimidine derivative, characterized by a six-membered ring containing two nitrogen atoms. Subheading 2933.52 is a specific provision for malonylurea (barbituric acid) and its salts. The classification is straightforward under GRI 1, as the chemical name is explicitly mentioned in the Harmonized System legal text. Barbituric acid serves as the parent compound for a wide range of barbiturate drugs, although the acid itself is not pharmacologically active as a central nervous system depressant. In its pure chemical form, or as a salt, it remains in Chapter 29. If the substance were prepared as a medicament in measured doses, the classification would shift to Chapter 30, but as a raw chemical compound, 2933.52 is the correct designation.

Products Included

• Malonylurea (Barbituric acid)
• Sodium barbiturate (salt of malonylurea)
• Ammonium barbiturate
• Calcium barbiturate
• Other metallic salts of barbituric acid

Common Misclassification

A frequent misclassification occurs with HS code 2933.53, which covers specific derivatives like allobarbital, amobarbital, and pentobarbital. While these are derived from malonylurea, they are distinct chemical entities with their own specific subheadings. Additionally, importers sometimes confuse this with 3004.90, which covers medicaments. However, unless the malonylurea is put up in measured doses or in forms for retail sale for therapeutic use, it must remain in the organic chemicals chapter under 2933.52.

FAQ

What is the HS code for Malonylurea?

The HS code for Malonylurea (also known as barbituric acid) and its salts is 2933.52.

Is barbituric acid classified the same as barbiturate drugs?

No, while they are related, barbituric acid is under 2933.52, whereas many specific barbiturate derivatives like phenobarbital are classified under 2933.53 or 2933.54.
