Hydraulic lime plays a crucial role in various construction and infrastructure projects. Categorized under HS Code 25223000, hydraulic lime is distinct from calcium oxide and hydroxide of heading 2825. In this article, we will delve into the details of this HS code, its product description, and other relevant information.
The product described by HS Code 25223000 refers to hydraulic lime, which is specifically different from calcium oxide and hydroxide falling under heading 2825. Hydraulic lime is commonly used in the construction industry due to its unique property of setting and hardening even when in contact with water. This distinguishes it from non-hydraulic lime, which requires air to set and harden.
Hydraulic lime is produced by burning limestone containing clay or silica at a relatively low temperature. This process retains the clay or silica, resulting in a product that can set and harden when exposed to water. Its ability to set underwater makes it suitable for various applications, including the construction of bridges, dams, and other structures that are constantly exposed to moisture.
The bound or most-favored-nation (MFN) duty rate for HS Code 25223000 is free. This means that whenever a country lowers a trade barrier or opens up a market, it must do so for hydraulic lime from all its trading partners. This duty rate facilitates international trade by ensuring fair treatment of importers and exporters dealing with hydraulic lime.
The quantity unit for HS Code 25223000 is kilograms (KG). This unit of measurement is widely used in international trade to determine the weight of hydraulic lime being imported or exported. It allows for accurate calculation of quantities and ensures consistency in trade transactions.
Special tariff preference programs may exist for the import and export of hydraulic lime under HS Code 25223000. These programs aim to promote trade and economic cooperation between countries by providing preferential treatment to certain goods. It is essential for importers and exporters to be aware of any such programs that may offer reduced duty rates or other benefits for hydraulic lime trade.
The United States is both an importer and exporter of hydraulic lime under HS Code 25223000. Several states engage in the import and export of this essential construction material. One notable importing state is Montana, which sources hydraulic lime from various trading partners to meet its construction needs. On the other hand, numerous states within the US export hydraulic lime to cater to international demands.
Overall, HS Code 25223000 plays a significant role in facilitating the global trade of hydraulic lime. Its distinct classification, duty rate, and quantity unit contribute to the smooth flow of this essential construction material across borders. Understanding the details of this HS code is crucial for importers, exporters, and industry professionals involved in the construction sector.
