About Duty Rates: Rates are divided into Column 1 and Column 2. Column 1 is subdivided into General (normal trade relations rates for all countries not eligible for special programs) and Special (preferential rates for countries with free trade agreements or preference programs). Column 2 rates apply to products from Cuba, North Korea, Belarus, and Russia. When no special rate exists for a classification, General rates apply.

Overview

This HTS classification pertains to specialized optical attenuators. These devices are engineered to precisely reduce the power level of an optical signal, functioning in either free-space optical transmission or within optical fibers. Crucially, this classification is reserved for such instruments and apparatus that are specifically designed and intended for use within telecommunications systems.

Distinguishing this category from other potential classifications is paramount. While other categories may cover general optical components or scientific instruments, this 9902.17.27 classification is narrowly defined by its specific function (power reduction of optical signals) and its dedicated application in telecommunications. It is important to note that this classification is established under temporary legislation and is provided for in subheading 9013.80.90, indicating a specific temporary provision rather than a permanent classification under the main body of the HTS.

As this is a leaf node within the HTS database, there are no further subcategories. Therefore, the focus remains on the precise definition of "optical attenuators designed to reduce the power level of an optical signal, either in free space or in an optical fiber, such instruments or apparatus specifically designed for telecommunications." Importers must ensure their goods meet both the functional and intended use criteria to correctly classify under this provision.
