Box 639 Chatham, NJ 07928 RE: The tariff classification of Halcinonide (CAS No. 3093-35- 4), Oxymetazoline Hydrochloride (CAS No. 2315-02-8), Megestrol Acetate (CAS No. 595-33-5), and Thonzonium Bromide (CAS No. 553- 08-2), all imported in bulk form, from Italy. Dear Ms. Agnello: In your letter dated March 30, 1992, you requested a tariff classification ruling. Halcinonide is a synthetically-derived glucocorticoid (a steroid hormone produced by the adrenal cortex). It is the active ingredient in several topical preparations used for the relief of the inflammatory and pruritic manifestations of corticosteroid- responsive dermatoses. Oxymetazoline Hydrochloride is a topical nasal decongestant. Megestrol Acetate is a steroid hormone belonging to a group of steroid hormones, called progestins or progestogens, having progesterone as their precursor. It is very potent in inhibiting ovulation, and is employed outside the U.S. as an oral contraceptive. In the U.S., it is used for palliative treatment of inoperable advanced carcinoma of the breast or endometrium, as an adjunct to other therapy. Its therapeutic effect is based on its hormonal activity. It is always administered as the acetate. Thonzonium Bromide is a detergent. It is used as a component of certain drugs. The applicable subheading for Halcinonide will be 2937.22.0000, Harmonized Tariff Schedule of the United States (HTS), which provides for adrenal cortical hormones and their derivatives: halogenated derivatives of adrenal cortical hormones.
