The tariff classification of gas monitors from England.
NY 851139 APR 24 1990 CLA-2-90:S:N:N1:104 851139 CATEGORY: Classification TARIFF NO.: 9027.10.2000 Mr. Derek J. Day Neotronics North America, Inc. P.O. Box 370 2144 Hilton Drive Gainesville, GA 30501-6153 RE: The tariff classification of gas monitors from England. Dear Mr. Day: In your letter dated April 4, 1990 you requested a tariff classification ruling. The Exotox Multi-Gas Monitor can monitor up to four gases simultaneously. The sensors, which operate on a concentration basis, provide a stable output over a wide range of atmospheric pressures and temperatures. The sensor types include electrochemical for monitoring oxygen, carbon monoxide, hydrogen sulfide and sulfur dioxide and a low power pellister for combustibles. The monitor provides a direct digital readout of gas concentration. An alarm condition can be indicated by a high noise output sounder or by a visual warning symbol. The Neotox Personal Gas Monitors include five separate pocket-size instruments for monitoring potentially dangerous gases where single gas hazards exist. They include the Neotox Personal Oxygen Deficiency and Enrichment, Chlorine, Carbon Monoxide, Sulfur Dioxide, and Hydrogen Sulfide Monitors. All employ electrochemical sensors operating on a concentration basis. These monitors also provide a direct digital readout of gas concentration and have sound and visual alarm condition indicators. The applicable subheading for the Exotox and Neotox Gas Monitors will be 9027.10.2000, Harmonized Tariff Schedule of the United States (HTS), which provides for gas or smoke analysis apparatus. The rate of duty will be 4.9 percent ad valorem. This ruling is being issued under the provisions of Section 177 of the Customs Regulations (19 C.F.R. 177). A copy of this ruling letter should be attached to the entry documents filed at the time this merchandise is imported. If the documents have been filed without a copy, this ruling should be brought to the attention of the Customs officer handling the transaction. Sincerely, Jean F. Maguire Area Director New York Seaport
