The rubber/textile material weighs 4145 grams per square meter, and has a rubber content of 2225 grams. This construction is considered to be a rubber for tariff purposes. The applicable subheading for the rubber crash-resistant fuel cell will be 4016.99.5050, Harmonized Tariff Schedule of the United States (HTS), which provides for other articles of vulcanized rubber other than hard rubber, other. The rate of duty will be 5.3 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.
