Ceramic chimney-pots, cowls, chimney liners, architectural ornaments and other constructional goods (excluding roofing tiles)

HS code 690590 covers a range of ceramic construction materials, including chimney-pots, cowls, chimney liners, and architectural ornaments. These products play a crucial role in the building and construction industry, ensuring the proper ventilation and aesthetic appeal of structures. As a key component of many construction projects, the 690590 industry is an important contributor to the broader economy, supporting activities in 4400 Construction and 4300 Architectural and engineering activities; technical testing and analysis.

The production of 690590 goods typically involves the shaping, firing, and finishing of ceramic materials. Clay is the primary raw material, which is molded into the desired shapes using techniques such as extrusion, pressing, or slip casting. The shaped pieces are then fired in high-temperature kilns to harden and vitrify the ceramic. Depending on the specific product, additional finishing steps may be applied, such as glazing, painting, or polishing, to enhance the appearance and durability of the final items.

The main inputs for the 690590 industry include clay, water, and energy sources for firing the ceramics. Specialized machinery, such as extruders, presses, and kilns, are also essential for the production process. Additionally, the industry may rely on various additives, such as glaze materials, to achieve specific aesthetic or functional properties in the final products.

The primary outputs of the 690590 industry are the ceramic construction goods themselves, which are used in a variety of building and architectural applications. These products may be consumed by 4300 Architectural and engineering activities; technical testing and analysis, 4400 Construction, and 4390 Other specialized construction activities industries, among others. The 690590 industry also produces materials that may be used in 2342 Manufacture of ceramic sanitary fixtures, 2349 Manufacture of other ceramic products, and 2331 Manufacture of ceramic tiles and flags, further contributing to the broader construction and building materials sectors.
