Welding machines and apparatus; for resistance welding of metal, fully or partly automatic, whether or not capable of cutting

HS v2022 Code: 851521

About welding machines and apparatus; for resistance welding of metal, fully or partly automatic, whether or not capable of cutting

HS code 851521 covers a critical segment of the metal fabrication industry, encompassing welding machines and apparatus used for resistance welding of metal. These specialized machines play a vital role in the production of a wide range of metal products, from automotive components to construction materials, making them an essential part of the broader manufacturing ecosystem.

Production process

Resistance welding is a key production technique utilized by industries covered under HS code 851521. This process involves the use of electrodes to pass an electric current through the metal parts being joined, generating heat and pressure to fuse the materials together. Welding machines can be fully or partly automatic, allowing for precise control and consistency in the welding process.

Production inputs

The primary inputs for the industry described by HS code 851521 include various metal materials, such as steel, aluminum, and other alloys, as well as the specialized welding machines and equipment. These machines often require advanced electrical and electronic components, as well as a skilled workforce capable of operating and maintaining the equipment.

Production outputs

The output of the industry covered by HS code 851521 is primarily welded metal products, which are then used as inputs for a wide range of downstream industries. These may include 870000 Motor vehicles, parts and accessories, 730000 Iron and steel, and 940000 Furniture; bedding, mattresses, mattress supports, cushions and similar stuffed furnishings; lamps and lighting fittings, not elsewhere specified or included; illuminated signs, illuminated name-plates and the like; prefabricated buildings.

Revisions to 851521

Classification codes are adjusted frequently. The code may have been revised or replaced between system versions. The table below shows the history (newest to oldest) of the code 851521. The most recent 1 version of this code (851521) is in the HS v2022 system (this version):
