Overview

This HTS classification, 8518.40.10.00, specifically covers audio-frequency electric amplifiers designed and intended for use as repeaters in line telephony systems. These are specialized amplifiers crucial for strengthening and relaying telecommunication signals over telephone lines, ensuring signal integrity and range. The "repeaters in line telephony" designation is a key defining characteristic, distinguishing them from general-purpose amplifiers.

In contrast to its sibling category, 8518.40.20.00, which encompasses "Other" audio-frequency electric amplifiers, this specific classification is limited to those with a dedicated function within telecommunication networks. The "Other" category would include amplifiers used in home audio systems, public address systems, musical instrument amplification, or any other application not directly related to telephone line signal repetition.

As this is a leaf node in the HTS classification, there are no further subcategories. Therefore, classification within 8518.40.10.00 hinges solely on the item's explicit design and function as a telephone line repeater. Importers must ensure that the product documentation and physical characteristics clearly support this specific application to correctly classify the goods under this heading.
