HS Code 25199020 - Caustic Calcined Magnesite: An Essential Ingredient in Various Industries

The HS Code 25199020 represents the product "Caustic calcined magnesite." This article aims to provide comprehensive information about this product, its uses, and its significance in various industries.

Product Description

Caustic calcined magnesite, as indicated by its name, is a type of magnesite that has undergone a calcination process. The calcination process involves heating magnesite to high temperatures, resulting in the removal of carbon dioxide and other impurities. This process transforms magnesite into a caustic and reactive material.

Caustic calcined magnesite is known for its high magnesium oxide (MgO) content, typically ranging from 85% to 97%. It has a white or grayish-white color and a powdery texture. The product is commonly available in the form of lumps, granules, or powder.

Uses of Caustic Calcined Magnesite

Caustic calcined magnesite finds wide applications in various industries due to its unique properties. Some of its primary uses include:

• Refractory Industry: Caustic calcined magnesite is a crucial component in the production of refractory materials, including bricks, castables, and gunning mixes. Its high melting point and resistance to heat make it an ideal material for lining furnaces, kilns, and other high-temperature environments.
• Agricultural Industry: Magnesium plays a vital role in plant growth and development. Caustic calcined magnesite is often used as a fertilizer to supply magnesium to deficient soils. It helps improve soil fertility, enhance crop yield, and promote overall plant health.
• Water Treatment: The alkaline nature of caustic calcined magnesite makes it suitable for water treatment applications. It can be used to neutralize acidic water, regulate pH levels, and remove impurities such as heavy metals.
• Chemical Industry: Caustic calcined magnesite serves as a raw material in the production of various chemicals, including magnesia-based products, magnesium salts, and magnesium hydroxide. These chemicals find application in industries like pharmaceuticals, ceramics, and flame retardants.
• Animal Feed: Magnesium is an essential nutrient for animals. Caustic calcined magnesite is often included in animal feed formulations to meet their dietary magnesium requirements. It helps improve bone health, enzyme function, and overall animal well-being.

Bound / MFN Duty Rate

The bound / MFN (Most Favored Nation) duty rate for HS Code 25199020 is free. This means that every time a country lowers a trade barrier or opens up a market, it must do so for the same goods or services from all its trading partners. This duty rate promotes fair trade practices and equal treatment among nations.

Quantity Unit

The quantity unit for HS Code 25199020 is metric tons (T). This unit of measurement is commonly used in international trade to quantify the volume or weight of goods being imported or exported.

Special Tariff Preference Programs

Caustic calcined magnesite may be eligible for special tariff preference programs aimed at promoting trade and economic cooperation between countries. These programs provide certain benefits, such as reduced or waived import duties, to eligible importers or exporters. Some examples of such programs include:

• Generalized System of Preferences (GSP): The GSP program grants preferential tariff treatment to products imported from developing countries.
• Free Trade Agreements (FTAs): FTAs establish mutually beneficial trade terms between participating countries, including tariff reductions or eliminations for specific products.
• Regional Trade Agreements (RTAs): RTAs promote trade integration within a specific region, leading to preferential tariff arrangements for member countries.

Importing and exporting US states may also have their own specific programs or incentives to support the trade of caustic calcined magnesite.

HS Code 25199020 represents caustic calcined magnesite, a versatile product with significant applications in refractory, agricultural, water treatment, chemical, and animal feed industries. Its unique properties, including high magnesium oxide content, make it indispensable in various manufacturing processes. Understanding the HS code, duty rates, and special tariff preference programs associated with this product is essential for businesses involved in international trade.
