Harmonised System of Nomenclature, or HSN codes, are six-digit identification codes that categorize goods in international trade. It was in 1988 that the World Customs Organization (WCO) introduced the HSN, also known as HS codes. The HSN codes classify more than 98% of goods in modern-day and global trade.

 In India, in a bid to replace several indirect taxes that were prevalent earlier in the country, the government introduced the Goods and Service Tax, also known as the GST. Central Goods and Service Tax (CGST), State Goods and Service Tax (SGST), and Integrated Goods and Services Tax (IGST) are the three types of GST. One of the HSN codes aims to make the GST systematic and universally accepted. Furthermore, HSN codes will eliminate the need to upload a detailed description of the goods. Besides saving time, it will make filing easier since GST returns are automated.

Under India’s GST system, all registered taxpayers involved in the supply of goods are eligible to use HSN codes. These codes classify goods and services for taxation purposes, making determining the applicable GST rate easier. Specific HSN codes apply to chemical products. A substance obtained by a chemical process or that produces a chemical effect is a chemical.

HSN codes that apply to chemical products

The Harmonized System of Nomenclature (HSN) codes play a pivotal role in classifying and identifying chemical products in India. Under the HSN, chemical products are systematically categorized to facilitate international trade and ensure uniformity in customs procedures. The HSN code for chemical products in India generally falls under Chapters 28–38.

 Chapter 28 encompasses inorganic chemicals, while Chapter 29 covers organic chemicals. Agrochemicals, such as fertilizers and pesticides, are classified under Chapters 31 and 38, respectively. Dyes and pigments are classified in Chapter 32, while plastics and polymers are classified in Chapter 39. Pharmaceutical products, including bulk drugs and formulations, are categorized under Chapter 30 or 3003.

Essential oils, perfumery, cosmetics, or toilet preparations are assigned HSN codes in Chapter 33, while rubber and rubber products are covered under Chapter 40. Paints, varnishes, and inks fall under Chapter 32 or 3210, and explosives and fireworks are classified in Chapter 36.

The specificity of HSN codes ensures accurate identification during import and export processes, aiding in efficiently applying taxes and duties. Importers and exporters must diligently use the appropriate HSN codes for their chemical products to comply with regulatory requirements and enjoy smooth cross-border transactions. Regular updates to the HSN code list are essential, reflecting changes in the chemical industry and international trade practices and ensuring precision and alignment with global standards. The HSN code system not only simplifies customs procedures but also enhances transparency and coherence in the classification of chemical products, contributing to the overall efficiency of India’s trade ecosystem.

Why is there a separate HSN code for import and export?

Using separate Harmonized System of Nomenclature (HSN) codes for imports and exports serves several practical and administrative purposes.

Customs Classification

HSN codes are a standardized international system for the classification of products. Having separate codes for import and export helps customs authorities and traders accurately classify and identify goods during both inbound and outbound shipments.

Customs Documentation

Customs documentation, including invoices and shipping declarations, requires the inclusion of HSN codes. Separating the codes for import and export ensures that the correct code is specified according to the direction of the trade, helping customs authorities in the destination and origin countries process shipments efficiently.

Tariff Determination

Countries may have varying tariff rates and import/export regulations for the same product. Using separate HSN codes, customs authorities can apply the appropriate tariff rates and regulatory measures specific to the importing or exporting country.

Trade Statistics

Separating import and export HSN codes facilitates the compilation of accurate trade statistics. Governments and international organizations use this data to analyze trade trends, monitor economic activity, and formulate trade policies. Distinct codes help in generating precise import and export statistics.

Risk Assessment

Customs authorities use HSN codes to conduct risk assessments and ensure compliance with trade regulations. Having separate codes for import and export helps in conducting targeted assessments based on the direction of trade, allowing authorities to focus on potential risks associated with specific goods.

Alignment with National Policies

Some countries may have specific policies or regulations related to the imports or exports of certain products. Separate HSN codes allow for the alignment of classification systems with national policies and regulatory frameworks, enabling better control over the movement of goods.

Separate HSN codes for import and export streamline customs procedures, facilitate accurate documentation, and ensure that trade activities align with the exporting and importing countries’ specific regulatory requirements and tariff structures. This separation enhances the efficiency and accuracy of international trade transactions.
