Pickling preparations for metal surfaces; soldering, brazing or welding powders and pastes consisting of metal and other materials

HS code 381010 covers a range of chemical preparations used in the metalworking industry. These products play a crucial role in the surface treatment and joining of metals, enabling critical industrial processes like welding, brazing, and pickling. As a key input for various manufacturing sectors, the 381010 industry is an integral part of the broader global economy, supporting the production of a wide array of metal-based goods and infrastructure.

The main production techniques for HS code 381010 items involve the formulation and blending of specialized chemical compounds. Manufacturers typically start with base metal powders or compounds, which are then combined with other materials such as fluxes, binders, and solvents. The specific composition and processing methods can vary depending on the intended application, whether it be pickling preparations, soldering pastes, or welding powders. Careful quality control and testing are essential to ensure the final products meet industry standards and performance requirements.

The primary inputs for the 381010 industry include metal powders or compounds (e.g., 720421 Ferrous waste and scrap; remelting scrap ingots of iron or steel, 810120 (Tungsten (wolfram) and articles thereof, including waste and scrap)), various chemical additives (e.g., fluxes, binders, solvents), and specialized production equipment. Manufacturers in this sector rely on a steady supply of these raw materials and technologies to formulate their specialized metal surface treatment and joining products.

The main outputs of the 381010 industry are the pickling preparations, soldering/brazing/welding powders and pastes that are consumed by a wide range of metalworking and fabrication industries. These products are used in the production of 730110 Sheet piling of iron or steel, 730890 (Structures and parts of structures (for example, bridges and bridge-sections, lock-gates, towers, lattice masts, roofs, roofing frameworks, doors and windows and their frames and thresholds for doors, shutters, balustrades, pillars and columns), of iron or steel, n.e.s.; plates, rods, angles, shapes, sections, tubes and the like, prepared for use in structures, of iron or steel), and other metal-intensive goods. The 381010 industry supports the broader metalworking and fabrication sectors by enabling critical surface treatment and joining processes.
