U.S. imports of non-automatic electric arc welding machines & apparatus (HS 851539) totaled $13.0M in June 2026, traded with 21 countries.
Importers of Non-Automatic Electric Arc Welding Machines & Apparatus paid $1.3M in duties in June 2026 — an effective duty rate of 15% on $8.9M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: June 2026 dataImports of Chinese-origin arc welding equipment under this heading are subject to Section 301 tariffs, making origin and classification review a priority for procurement teams. The US schedule distinguishes three configurations: AC transformer-type non-rotating welders (8515390020), other non-rotating arc welding machines (8515390040), and rotating-type arc welding machines (8515390060). Mexico leads US supply, followed by China and Vietnam, reflecting both nearshore manufacturing and global electronics supply chains. Plasma arc equipment falls within this heading provided the machine is not fully or partly automatic, a distinction that frequently requires careful technical documentation at entry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
The key criterion is whether the machine requires continuous manual operator intervention to control the welding process. Machines with automatic feed, sequencing, or positioning controls — even partial — typically fall under the fully or partly automatic subheadings rather than 851539. Importers should obtain detailed technical specifications from the manufacturer and consult a licensed customs broker to confirm classification before entry.
Yes — electric plasma arc welding machines are explicitly included within this heading, provided they are not fully or partly automatic. If the plasma arc unit incorporates automatic controls, it would instead fall under the automatic arc welding subheadings of heading 8515.
