HS Code Singapore: Understanding the Harmonized System Code for Imports and Exports
If you’re involved in importing or exporting goods in Singapore, you may have heard of HS codes. HS codes, or Harmonized System codes, are used globally to classify and identify products for customs purposes. In Singapore, HS codes are based on the ASEAN Harmonized Tariff Nomenclature (AHTN), which is a classification system developed by the World Customs Organization (WCO).

Understanding HS codes in Singapore is essential for anyone involved in international trade. Each product is assigned a unique HS code, which is used to determine the applicable customs duties and taxes. It’s important to ensure that your products are correctly classified to avoid any delays or penalties. Singapore Customs provides a range of resources to help you determine the correct HS code for your products, including the HS/CA Product Code search engine and the Traders’ Product Guide.
Navigating the regulatory aspects and customs procedures of international trade can be challenging, but having a good understanding of HS codes can help simplify the process. In this article, we’ll take a closer look at HS codes in Singapore, including how they work, how to determine the correct code for your products, and some frequently asked questions.

Understanding HS Codes in Singapore

If you are involved in international trade, you may have come across the term “HS Code” or “Harmonised System Code”. HS Codes are used to classify goods for customs purposes. In Singapore, the HS Code system is based on the ASEAN Harmonised Tariff Nomenclature (AHTN) and is administered by the Singapore Customs.
Basics of HS Code Structure
HS Codes are made up of six digits, which are used to identify the product being imported or exported. The first two digits represent the chapter, which broadly categorises the product. The next two digits represent the heading, which narrows down the category further. The final two digits represent the subheading, which provides a more specific description of the product.
Singapore Trade Classification and HS/CA Product Code Search Engine
The Singapore Trade Classification, Customs and Excise Duties (STCCED) is used to classify goods for customs purposes in Singapore. The HS/CA Product Code Search Engine is a tool provided by the Singapore Customs that allows you to search for HS codes, product codes and descriptions of a product within the STCCED. You can use the HS code provided by your overseas supplier as a reference and determine the 8-digit HS code from the search engine.
The Role of the World Customs Organisation
The World Customs Organisation (WCO) is an intergovernmental organisation that develops and maintains the Harmonised System (HS) for the classification of goods. The WCO works with member countries to ensure that the HS is updated regularly to reflect changes in trade patterns and technological developments.
ASEAN Harmonised Tariff Nomenclature (AHTN)
The AHTN is based on the 6-digit level HS Codes and is used by the ASEAN member countries to classify goods for customs purposes. Singapore adopts the 8-digit HS Codes in the AHTN. The AHTN allows for the uniform classification of goods across the ASEAN region, which facilitates trade between member countries.
In summary, understanding HS Codes is important for anyone involved in international trade. The HS/CA Product Code Search Engine provided by the Singapore Customs can help you determine the correct HS code for your product. The HS system is maintained by the WCO and is based on the AHTN, which is used by the ASEAN member countries.
Regulatory Aspects and Customs Procedures

Application for Customs Ruling
When importing or exporting goods, it is important to ensure that you have classified your goods correctly under the Harmonised System (HS) code. If you are unsure about the correct classification, you can apply for a customs ruling from the Singapore Customs. A customs ruling is a written decision by the customs authorities on the tariff classification, origin, or valuation of your goods. This will help you to determine the correct duties and taxes payable on your goods.
Controlled Goods and Competent Authorities
Certain goods are subject to control by the competent authorities in Singapore. These goods include strategic goods, hazardous chemicals, and certain food items. Before importing or exporting such goods, you must obtain the necessary permits and licenses from the relevant competent authorities. You can check if your goods are subject to control by using the HS/CA Product Code Search Engine provided by the Singapore Customs.
Import and Export Documentation
When importing or exporting goods, you must ensure that you have the necessary shipping documents. These include the invoice, packing list, bill of lading, and any other documents required by the customs authorities. You must also declare the correct value of your goods and provide accurate information about the origin and classification of your goods.
Understanding Duties and Taxes
Imported goods are subject to Goods and Services Tax (GST) and/or duty payment. The amount of duty and GST payable depends on the classification and value of your goods. You can use the HS/CA Product Code Search Engine to determine the applicable duties and taxes for your goods. It is important to note that failure to pay the correct duties and taxes can result in penalties and seizure of your goods by the customs authorities.
In summary, when importing or exporting goods in Singapore, it is important to ensure that you have classified your goods correctly under the HS code, obtained the necessary permits and licenses for controlled goods, and provided accurate information on your shipping documents. You must also pay the correct amount of duties and taxes payable on your goods to avoid penalties and seizure of your goods by the customs authorities. If you are unsure about any aspect of the customs procedures, you can seek advice from the Singapore Customs or use the TradeNet system to facilitate your trade processes.
