RE: Classification of Solberg’s Products under U.S. Section 232 Tariffs

Dear Valued Customer:

Thank you for your inquiry regarding the classification of Solberg’s products under the U.S. Section 232 tariffs. In relation to the Section 232 documentation mandate - Harmonized Tariff Schedule (HTS) Chapters 72, 73, and 76, which cover raw, semi-finished, and certain finished steel and aluminum products.

Solberg Manufacturing produces air filtration products that are classified under Harmonized Tariff Schedule (HTS) Chapter 84 (8421.39.XXXX) which covers filter apparatus and parts thereof. While some of our filter components may include steel and/or aluminum, these materials undergo substantial transformation during our manufacturing process. As a result, the final products-air filters-are not classified as steel or aluminum products nor their derivatives subject to Section 232 tariff and documentation mandate under Chapters 72, 73, and 76. Therefore, under current regulation, the smelt/melt data requirement does not apply to the products Solberg Manufacturing supplies.

Sincerely

Janet Luevano
Quality Manager
