RE: The tariff classification of Somatotropin (CAS-9002-76-6), imported in bulk form, from China

Dear Mr. Chivini:

In your letter dated March 28, 2006, you requested a tariff classification ruling.

The subject product, Somatotropin [also known as Growth Hormone (GH)], is a protein hormone, secreted by the anterior pituitary, that affects protein, carbohydrate, and lipid metabolism, and controls the rate of skeletal and visceral growth. Medicinal preparations containing Somatotropin are used to treat growth failure in children with a congenital deficiency of this hormone.

The applicable subheading for Somatotropin, imported in bulk form, will be 2937.11.0000, Harmonized Tariff Schedule of the United States (HTSUS), which provides for “Polypeptide hormones, protein hormones and glycoprotein hormones, their derivatives and structural analogues: Somatotropin, its derivatives and structural analogues.” The rate of duty will be free.

Duty rates are provided for your convenience and are subject to change. The text of the most recent HTSUS and the accompanying duty rates are provided on World Wide Web at
