North American Industry Classification System
U.S. imports of search, detection, navigation, guidance, aeronautical & nautical systems and instruments (NAICS 334511) totaled $668.0M in July 2026, traded with 95 countries.
Importers of Search, Detection, Navigation, Guidance, Aeronautical & Nautical Systems and Instruments paid $34.9M in duties in July 2026 — an effective duty rate of 12% on $288.3M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataRadar systems, sonar, inertial navigation units, GPS receivers, and related guidance instruments occupy a uniquely sensitive position in US trade law — many articles in this sector are dual-use goods subject to Export Administration Regulations (EAR) or, for military-grade items, the International Traffic in Arms Regulations (ITAR). Import classification under NAICS 334511 intersects with HTS chapters covering electronic navigation instruments, and buyers in aerospace, defense, and maritime industries must verify both the correct tariff schedule entry and any applicable export-control classification number (ECCN). Section 301 tariffs may apply to certain components sourced from China, and some defense-related articles require a Department of Commerce or State Department license regardless of trade direction.

ITAR applies when a navigation or guidance article is specifically designed, modified, or configured for military use and appears on the US Munitions List (USML). Even imported items can trigger ITAR obligations if the importer subsequently re-exports or transfers them. A licensed export-control attorney or compliance officer should review any article that may meet USML criteria before import.
The key distinctions are performance parameters (accuracy, anti-jamming capability, altitude/velocity limits) and intended end-use. Civilian GPS receivers with standard performance thresholds generally fall under commercial HTS provisions, while high-performance inertial navigation or guidance systems may require ECCN review and potentially a Commerce or State license. Consulting a licensed customs broker alongside an export-control specialist is advisable for borderline articles.
