Last updated: April 2026 dataDedicated components for compasses, GPS receivers, inertial navigation units, and other navigational appliances — such as sensor modules, display assemblies, and mounting hardware — are traded under this heading and serve marine, aerospace, and defense supply chains. The same dual-use and ITAR considerations that apply to finished navigational instruments extend to their parts, meaning that certain high-performance subassemblies may require export licensing even when imported for domestic repair or integration. Accurate technical documentation linking each part to its parent instrument type is essential for correct classification and compliance.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Supporting documentation should include the manufacturer's part number, a technical datasheet confirming the component's dedicated function within a specific navigational instrument, and ideally a bill of materials or assembly drawing. Customs may request this evidence to confirm that the article lacks independent utility outside the parent instrument, which is the standard for parts classification.
Yes. If the parent navigational instrument is controlled under the United States Munitions List (USML), its dedicated parts and components are typically controlled as well, regardless of whether they are imported separately. Importers should verify the USML or Commerce Control List status of any navigational subassembly with a licensed trade compliance attorney or export control specialist before importation or re-export.
