HS v2017 Code: 730449

About steel, stainless; (excluding cold-drawn or cold-rolled), tubes pipes and hollow profiles of circular cross-section

HS code 730449 covers the import and export of stainless steel tubes, pipes, and hollow profiles of circular cross-section, excluding those that have been cold-drawn or cold-rolled. This industry plays a vital role in the global manufacturing and construction sectors, providing essential components for a wide range of applications, from industrial equipment to infrastructure projects. The demand for these products is driven by the need for durable, corrosion-resistant materials that can withstand harsh environments and high-stress conditions.

Production process

The production of stainless steel tubes and pipes under HS code 730449 typically involves several key steps. First, stainless steel billets or slabs are heated and then extruded or drawn through a die to create the desired shape and size. The tubes and pipes may then undergo additional processing, such as annealing, to improve their mechanical properties and surface finish. In some cases, the products may be further shaped or fabricated to meet specific customer requirements.

Production inputs

The main inputs required for the production of stainless steel tubes and pipes under HS code 730449 include stainless steel raw materials, such as coils, sheets, or bars, as well as specialized machinery and equipment for the extrusion, drawing, and finishing processes. Additionally, energy sources, such as electricity or natural gas, are needed to power the production facilities, and skilled labor is required to operate the equipment and ensure quality control.

Production outputs

The primary outputs of the industry covered by HS code 730449 are stainless steel tubes, pipes, and hollow profiles of circular cross-section. These products are widely used in a variety of industries, including 731100 Boilers, machinery, mechanical appliances, nuclear reactors, parts thereof, 840721 Spark-ignition reciprocating or rotary internal combustion piston engines, and 870421 (Motor vehicles for the transport of goods, with compression-ignition internal combustion piston engine (diesel or semi-diesel)). The outputs of this industry may also be consumed by other industries that require durable, corrosion-resistant piping and tubing, such as the 860900 (Containers (including containers for the transport of fluids) specially designed and equipped for carriage by one or more modes of transport) and 870600 Chassis fitted with engines, for the motor vehicles of headings 87.01 to 87.05.
