8543.70.42.00 - Flight data recorders 🖩

This HTS classification, 8543.70.42.00, specifically covers Flight Data Recorders (FDRs). These are sophisticated electrical devices designed to record critical operational parameters of an aircraft during flight. Their primary function is to capture and store data such as airspeed, altitude, heading, control surface positions, and engine performance. This recorded information is invaluable for accident investigation, flight safety analysis, and performance monitoring.

At this level of the HTS, 8543.70.42.00 is distinguished from its sibling category, 8543.70.45.00, which is a residual category for "Other" electric synchros and transducers, and defrosters/demisters with electric resistors for aircraft. While all fall under the broader heading of "Other machines and apparatus, having individual functions, not specified or included elsewhere in this chapter," Flight Data Recorders possess a distinct and specialized purpose related to aviation safety and operational data logging. The sibling category is a catch-all for items that do not fit into the more specific classifications within this subheading.

As a leaf node, this classification does not have further subcategories. Therefore, classification under 8543.70.42.00 is definitive for any product meeting the definition of a Flight Data Recorder. Importers and exporters should ensure that the goods being declared are indeed designed and intended for the purpose of recording aircraft flight data to avoid misclassification.
