HS Code 73.12 – Stranded wire, ropes, cables, plaited bands, slings and the like, of iron or steel, not electrically insulated

HS code 7312 is a 4-digit heading in the Harmonized System that covers: Stranded wire, ropes, cables, plaited bands, slings and the like, of iron or steel, not electrically insulated. Heading 7312 encompasses a broad range of essential industrial and structural components: stranded wire, ropes, cables, plaited bands, slings, and similar articles, all made of iron or steel and crucially, not electrically insulated. This classification is vital for international trade as it covers the fundamental building blocks for countless applications across diverse sectors. The scope includes products formed by twisting or plaiting multiple strands of iron or steel wire together, creating items with enhanced strength and flexibility compared to single wires. Key sub-categories often differentiate by material grade (e.g., galvanized, stainless, high-carbon steel), construction type (e.g., 6x19, 6x37, non-rotating), and end-use application (e.g., hoisting, towing, rigging, structural support). Understanding these distinctions is paramount for trade compliance, as misclassification can lead to incorrect duties, delays, or even penalties. This heading specifically excludes electrically insulated cables, which fall under Chapter 85, and single, non-stranded wires (typically Chapter 72). The trade significance of these products is immense, forming the backbone of heavy construction, maritime transport, mining, oil and gas, and general manufacturing industries. Historically, the development of robust steel wire rope revolutionized engineering and logistics. As part of Section XV (Base Metals and Articles of Base Metal) and Chapter 73 (Articles of iron or steel), this heading emphasizes the fabrication of base metal into more advanced, functional forms, distinct from raw materials or simple wire.

Steel wire ropes for cranes, galvanized steel cables for suspension bridges, stainless steel aircraft cables, wire rope slings for lifting, plaited steel bands for heavy strapping, mooring ropes for marine vessels, guy wires for antenna towers, winch cables for off-road vehicles, elevator ropes, fishing trawler ropes, structural steel cables for architectural designs, non-rotating wire ropes, high-tensile steel wire for pre-stressed concrete, logging cables, galvanized steel fence wire (stranded), theatrical rigging cables, overhead power line support cables (non-insulated), mining hoist ropes, synthetic core wire ropes, drill line cables, tow cables, security barrier cables.

Common misclassification errors for Heading 7312 often involve confusing non-electrically insulated products with their insulated counterparts. Traders might mistakenly classify electrically insulated cables, which belong under HS 8544, here. The key distinction is the presence of an insulating sheath, making them electrical conductors, not just mechanical strength components. Another frequent mistake is classifying single, non-stranded wire (e.g., HS 7217 for iron/steel wire not plated or coated) or chains (HS 7315) under 7312. Heading 7312 specifically requires the product to be 'stranded,' 'ropes,' 'cables,' or 'plaited bands,' indicating multiple wires twisted together, not single wires or linked metal segments.

In 2025, the top exporters of HS code 7312 in UN Comtrade data were China ($2.9B, 35% of world exports), Vietnam (about $454M) and Germany ($452M). World exports came to about $8.1B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 7312 in UN Comtrade data were the United States ($950M, 12% of world imports), Germany ($373M) and Vietnam (about $334M). World imports came to about $8.2B, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 7312 is a 4-digit heading under Chapter 73 of the Harmonized System. The first 2 digits (73) identify the chapter, and digits 3-4 (12) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
