Coated calcium carbonate in India is a highly versatile industrial material widely used across multiple sectors, including plastics, paints, rubber, and construction. This specialized form of calcium carbonate is surface-treated with stearic acid or other compounds to enhance its performance in different applications. As international trade in coated calcium carbonate grows, understanding its Harmonized System (HS) code is crucial for importers, exporters, and businesses dealing with this material. The HS code allows for the proper classification of goods in global trade, ensuring compliance with customs regulations and facilitating smooth transactions. Let’s dive into the topic of coated calcium carbonate and its corresponding HS code, as well as the role it plays in the industrial world.

What is Coated Calcium Carbonate?

Coated calcium carbonate is created by treating natural calcium carbonate with a coating agent, typically stearic acid. This treatment alters the surface properties of calcium carbonate, making it hydrophobic (water-repellent) and improving its dispersion in non-polar materials like plastics and rubber. The result is a product with better processing characteristics and enhanced performance in various industrial applications.

The main advantage of coated calcium carbonate is its ability to integrate seamlessly into the manufacturing of plastic and polymer products. It helps improve product strength, durability, and smoothness, while also reducing production costs. Additionally, its non-toxic and eco-friendly nature makes it an ideal filler material for several industries.

The HS Code for Coated Calcium Carbonate

The HS code system is a standardized numerical method used to classify traded products. It was developed by the World Customs Organization (WCO) to ensure uniformity and consistency in the classification of goods across international borders. The code system is structured into 21 sections and 97 chapters, covering various commodities and products.

Coated calcium carbonate generally falls under the HS code category for "Natural calcium carbonate," but the specific classification can vary depending on its use and the country’s specific customs regulations. The most common HS code for calcium carbonate, including coated varieties, is:

HS Code: 28365000 – This code falls under Chapter 28, which deals with inorganic chemicals and compounds of precious metals, rare-earth metals, and radioactive elements. The full description for this code is "Calcium carbonate," and it includes both coated and uncoated forms.

For businesses engaged in international trade of coated calcium carbonate, using the correct HS code is crucial. Accurate classification ensures smooth customs clearance, appropriate tariff rates, and avoids delays in shipments.

Applications of Coated Calcium Carbonate

Coated calcium carbonate finds applications in a variety of industries due to its unique properties and benefits. Let’s explore some of the key sectors where this material is widely used:

1. Plastics Industry

In the plastics industry, coated calcium carbonate is a valuable additive used as a filler to reduce the cost of producing plastic products without compromising quality. It improves the stiffness and strength of the final product and enhances the smoothness of plastic surfaces. Its hydrophobic nature allows it to blend well with non-polar materials like polypropylene (PP) and polyethylene (PE), making it ideal for use in packaging films, bottles, and other plastic products.

2. Rubber Industry

In the rubber industry, coated calcium carbonate acts as a reinforcing filler. It improves the tensile strength, elasticity, and durability of rubber products, making them more resistant to wear and tear. Its water-repellent properties prevent moisture absorption, making it a preferred choice for outdoor applications like tires, hoses, and seals.

3. Paints and Coatings

Coated calcium carbonate is widely used in the production of paints and coatings as an extender pigment. It improves the opacity and brightness of the paint while also enhancing its durability and resistance to corrosion. This material is also used in powder coatings, where its fine particle size helps achieve a smooth finish and improve flow properties.

4. Construction Materials

In the construction sector, coated calcium carbonate is used as a filler in adhesives, sealants, and concrete products. Its inclusion improves the strength, workability, and overall performance of these materials. Additionally, it is used in the manufacturing of ceramic tiles, where it contributes to the tiles' smooth texture and durability.

5. Paper Industry

Coated calcium carbonate plays a vital role in the paper industry as a filler and coating agent. It improves the brightness, smoothness, and opacity of paper, making it more suitable for high-quality printing. Its use in coated paper also enhances the ink receptivity and print quality.

Importance of Correct HS Code Usage in International Trade

Accurate classification of coated calcium carbonate under the HS code system is essential for smooth international trade. Using the correct HS code, such as 28365000, ensures that products are subject to the right tariffs, duties, and regulations. Incorrect classification can lead to issues such as shipment delays, additional fees, and potential fines from customs authorities.

Moreover, when importing or exporting coated calcium carbonate, businesses need to consider other factors like country-specific regulations, certificates of origin, and safety documentation. Staying compliant with customs regulations helps avoid unnecessary complications during the shipping process.

Conclusion

Coated calcium carbonate is a valuable material with a wide range of industrial applications. Its enhanced properties, such as hydrophobicity and better dispersion in non-polar substances, make it a popular choice in industries like plastics, rubber, paints, and construction. Understanding the HS code, particularly 28365000 for coated calcium carbonate, is crucial for businesses involved in international trade to ensure seamless transactions and compliance with customs regulations.
