North American Industry Classification System
U.S. imports of electronic connectors, including parts (NAICS 334417) totaled $420.9M in July 2026, traded with 79 countries.
Importers of Electronic Connectors, Including Parts paid $41.3M in duties in July 2026 — an effective duty rate of 15% on $278.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Electronic Connectors, Including Parts imports of $420.9M in July 2026 ran 22% above the year-to-date monthly average of $345.0M.
Last updated: July 2026 dataElectronic connectors — including board-to-board, wire-to-board, RF, and fiber-optic interface types — are engineered to precise mechanical and electrical tolerances, and their HTS classification turns on contact material, connector type, and whether parts or complete assemblies are being imported. Section 301 tariffs apply to many connector types of Chinese origin, creating sourcing pressure toward suppliers in Vietnam, Taiwan, and Mexico. Parts of connectors (contacts, housings, and shells imported separately) may be classified differently from finished connectors, a distinction that affects both duty liability and rules-of-origin calculations for downstream assemblies.

Connector contacts, housings, and shells imported separately may fall under different HTS subheadings than finished connectors, sometimes with lower duty rates. However, CBP scrutinizes whether separately imported parts are being used to circumvent antidumping or Section 301 orders on finished connectors. Importers should document the genuine manufacturing use of parts and consult a customs broker before structuring procurement around parts-versus-finished-goods distinctions.
Contact material (gold-plated vs. tin-plated), current rating, and whether the connector is coaxial (RF) versus multi-pin are the most common reclassification triggers. Coaxial RF connectors and fiber-optic connectors occupy distinct HTS headings from standard multi-pin connectors. Providing CBP with manufacturer datasheets that clearly state these parameters at entry reduces the risk of a CF-28 request for additional information.
