About iron or steel wire; grill, netting and fencing, welded at the intersection, n.e.c. in item no. 7314.20, (other than plated or coated with zinc)

HS code 731439 covers a wide range of iron or steel wire products, including grills, netting, and fencing that are welded at the intersection. These products are essential components in various industries, from construction and infrastructure to agriculture and manufacturing. They play a crucial role in providing structural support, security, and protection across diverse applications within the global economy.

Production process

The production of items under HS code 731439 typically involves a multi-step process. First, steel wire is drawn to the desired thickness and tensile strength. The wire is then cut to the appropriate lengths and welded at the intersection points to form the desired grill, netting, or fencing patterns. Finally, the welded structures may undergo additional finishing processes, such as galvanization or other protective coatings, depending on the intended application.

Production inputs

The main inputs required for the production of items under HS code 731439 include steel wire, welding equipment, and various tools and machinery for cutting, shaping, and assembling the final products. Depending on the specific application, additional inputs such as protective coatings or specialized fasteners may also be required.

Production outputs

The primary outputs of the industry covered by HS code 731439 are various types of iron or steel wire grills, netting, and fencing products. These outputs are often consumed by industries such as 731420 Iron or steel wire, grill, netting and fencing, welded at the intersection, 731010 (Tanks, casks, drums, cans, boxes and similar containers, for any material (other than compressed or liquefied gas), of iron or steel, of a capacity not exceeding 300 l, not fitted with mechanical or thermal equipment), and 940600 Prefabricated buildings, among others, where they are used for a wide range of applications, including security, protection, and structural support.
