HS Code for Erythromycin

Erythromycin is classified under HS code 2941.50 because it is a specifically identified antibiotic within the organic chemicals sector of the Harmonized System. According to the General Interpretative Rules (GRI 1), classification is determined by the terms of the headings and any relative section or chapter notes. Heading 2941 is dedicated to antibiotics, which are defined as substances produced by microorganisms that inhibit the growth of or destroy other microorganisms. Erythromycin, a macrolide antibiotic, is explicitly named in the subheadings. For a product to remain in Chapter 29, it must be a separate chemically defined compound, even if it contains impurities. This code covers the bulk active pharmaceutical ingredient (API) rather than the finished dosage form. The classification also encompasses the various salts and derivatives of erythromycin, such as erythromycin stearate or erythromycin ethylsuccinate, provided they retain the essential chemical character of the parent antibiotic and are not more specifically provided for elsewhere in the tariff schedule.

Products Included

• Bulk erythromycin base
• Erythromycin stearate (salt)

• Purified erythromycin for laboratory use

Common Misclassification

The most frequent misclassification occurs with HS code 3004.10 or 3004.20. While Chapter 29 covers bulk chemicals and antibiotics as raw materials, Chapter 30 is reserved for medicaments consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses or in forms or packings for retail sale. If the erythromycin is in the form of tablets, capsules, or ointments ready for patient use, it must be moved to 3004. Additionally, some confuse it with 2941.90, which is the residual category for other antibiotics; however, since erythromycin is specifically named in 2941.50, the specific code takes precedence over the general one.
