NMFC Class 50 — packaging, handling, and freight class details
Copper and brass are among the most valuable and densely shipped metals in the freight market. Copper wire and cable move from wire drawing mills to electrical distributors, construction sites, and manufacturing plants in large volumes. Copper pipe and fittings supply plumbing and HVAC distributors. Brass fittings, valves, and machined parts move through industrial distribution channels. The market for copper is global, with significant volumes moving through domestic service centers like Ryerson, Metals USA, and regional copper distributors.
Copper density is extreme — solid copper is 559 lbs/cuft, and even copper wire in coiled form or copper pipe in bundles achieves 50–150 lbs/cuft depending on packing efficiency. This always qualifies for Class 50 without exception. Combined with copper's value (typically $3.50–$4.50+ per pound), copper freight is simultaneously the most density-efficient and highest-value-per-pound common metal category.
Security is the defining concern for copper freight that distinguishes it from all other metals. Copper theft is a multi-billion dollar annual problem in the US. Copper wire and cable, pipe, and scrap are regularly stolen from job sites, utility facilities, and vehicles. A pallet of copper wire can weigh 2,000 lbs with a value of $7,000–$9,000 — a tempting target. Carriers transporting copper should use sealed cargo containers or fully enclosed trailers with cargo seals, should not discuss the load contents, and should park only in secured, monitored locations overnight.
For scrap copper and brass — from demolition projects, manufacturing offcuts, and recycling streams — freight is typically moving to scrap dealers and recycling facilities. Scrap copper loads are often irregularly shaped and require careful blocking and bracing on flatbed. The value of scrap copper still makes security important even for recycling-bound material. Rate context: copper and brass freight at Class 50 pays at the lowest class rate, but the high value justifies premium security provisions. High-value copper cable and wire shipments for utility or data center projects can command above-market rates from shippers who prioritize security over cost.
