Iron of steel; barbed wire, twisted hoop or single flat wire and loosely twisted double wire, used for fencing

HS code 731300 covers a range of steel products used primarily in fencing applications. These items, including barbed wire, twisted hoops, and flat wire, are essential components in the construction and maintenance of various types of fences, from agricultural to industrial settings. As a key part of the broader steel industry, the production and trade of these fencing materials play a vital role in supporting infrastructure development, agricultural activities, and the overall economy.

The production of the items covered under HS code 731300 typically involves a series of metalworking processes. Steel wire is first drawn to the desired thickness and then subjected to various forming and twisting techniques to create the barbed, hooped, or flat configurations. Automated machinery is often used to ensure consistent quality and high-volume output. Heat treatment and galvanization processes may also be applied to enhance the durability and corrosion resistance of the final products.

The primary input for the production of HS code 731300 items is steel wire, which is sourced from 720810 Hot-rolled flat-rolled products of iron or non-alloy steel and 720711 Semi-finished products of iron or non-alloy steel. Additionally, the manufacturing process may require specialized equipment such as wire-drawing machines, twisting and bending tools, and galvanization facilities. Energy, labor, and transportation services are also essential inputs for this industry.

The main outputs of the HS code 731300 industry are the various types of fencing materials, including barbed wire, twisted hoops, and flat wire. These products are primarily consumed by the 441820 Builders' joinery and carpentry of wood and 251020 Natural calcium phosphates and natural aluminium calcium phosphates, and phosphatic chalk industries, which use them in the construction and maintenance of fences, enclosures, and other agricultural or industrial applications.
