Bituminous mixtures based on natural asphalt, on natural bitumen, on petroleum bitumen, on mineral tar or on mineral tar pitch (e.g. bituminous mastics, cut-backs)

HS code 271500 covers a diverse range of bituminous mixtures that are widely used in the construction and infrastructure industries. These materials, which are derived from natural and petroleum-based sources, play a crucial role in the development and maintenance of roads, highways, and other paved surfaces. As a key component of the global transportation network, the products under this code contribute significantly to economic growth and development.

The production of bituminous mixtures typically involves a combination of refining, blending, and processing techniques. Natural asphalt, bitumen, and mineral tars are often combined with various additives and fillers to create the desired properties and performance characteristics. The mixtures may undergo heating, emulsification, or other processing steps to achieve the required consistency and application-specific properties.

The main inputs for the production of bituminous mixtures under HS code 271500 include natural asphalt, natural bitumen, petroleum bitumen, mineral tar, and mineral tar pitch. Additionally, various additives such as fillers, modifiers, and emulsifiers may be incorporated to enhance the performance and characteristics of the final products. Specialized machinery and equipment, such as asphalt plants, mixing units, and application equipment, are also essential for the manufacturing and application of these materials.

The primary outputs of the industry covered by HS code 271500 are a diverse range of bituminous mixtures, including bituminous mastics, cut-backs, and other specialized products. These materials are widely used in the construction and maintenance of roads, highways, and other paved surfaces. The outputs of this industry may also be consumed by other industries, such as 271600 Petroleum bitumen, petroleum coke and other residues of petroleum oils or of oils obtained from bituminous minerals, which utilize bituminous products for various applications.
