Tariff classification
HTS codes: 2922.50.40
Headings: 2922
Product description
Among the chemicals listed was L-Tyrosine, which was classified in subheading 2922.50.50, HTSUSA. That classification was based upon an improper CAS number. The correct CAS number for L-Tyrosine is 60-18-4.
CBP rationale
L-Tyrosine is an amino-acid-phenol more properly classifiable in subheading 2922.50.40, HTSUSA, as an aromatic compound, whose CAS number is listed in the chemical appendix to the tariff schedules. The corresponding rate of duty is 3.7 cents per kilogram, plus 15.6 percent ad valorem.
