Communications Equipment

NAICS 3342 includes three main five-digit subsectors: telephone apparatus (33421), radio and television broadcasting and wireless communications equipment (33422), and other communications equipment (33429). Trade data aggregated at the 3342 level combines all three, so analysts comparing import trends should disaggregate to the five- or six-digit level for product-specific insights.

NAICS codes classify by manufacturing activity and product type, while HTS codes classify by physical characteristics and end use. A single communications device may map to different NAICS codes depending on whether it is classified by its primary function (e.g., telephone vs. wireless transceiver). Cross-walking between NAICS and HTS schedules requires care, and concordance tables published by the Census Bureau are the standard reference.
