U.S. imports of insulated electric conductors ≤1000 v, fitted with connectors, nesoi (HS 854442) totaled $858.2M in August 2026, imported from 104 countries.
Importers of Insulated Electric Conductors ≤1000 V, Fitted with Connectors, NESOI paid $222.9M in duties in August 2026, an effective tariff rate of 25.98% of the $858.2M imported — duty actually collected as a share of that value, not the published tariff schedule. Insulated Electric Conductors ≤1000 V, Fitted with Connectors, NESOI imports of $858.2M in August 2026 ran 11% above the year-to-date monthly average of $769.9M.
Last updated: August 2026 dataPre-terminated insulated conductors rated up to 1000 V — including extension cords, telecom patch cables, and modular-connector assemblies — are classified here, with the US schedule subdividing by voltage range and connector type. Dedicated lines cover conductors fitted with modular phone connectors in the 80–1000 V range (8544421000), telecom-grade insulated conductors (8544422000), extension cords (8544429010), and a broad NESOI line (8544429090). China is the leading import source, followed by Mexico and Vietnam. Chinese-origin goods across this heading are subject to Section 301 tariffs, a significant cost driver given China's dominant position.

Extension cords are specifically provided for under 10-digit line 8544429010 within this heading. The key classification factor is that the product is an insulated electrical conductor rated at or below 1000 V and fitted with connectors — the extension cord line captures those designed for general-purpose power extension, while telecom and modular-phone-connector products have their own dedicated lines.
Yes. The heading covers conductors up to 1000 V, but the 10-digit breakdown distinguishes conductors in the 80–1000 V range (e.g., 8544421000 for modular phone connector types) from the broader NESOI lines. Importers should confirm the conductor's rated voltage and connector type against the specific line descriptions to avoid misclassification.
