What is HS Code? How to lookup HS Code correctly

The HS Code is crucial for import and export activities as it appears on important documents like customs declarations, certificates of origin (CO/CQ), and commercial invoices. It provides basic data and directly influences tax rates and prices of goods during import and export processes. In the following article, we’ll be able to offer detailed information on HS Codes and how to look up HS codes accurately and easily.

What is HS Code? 

HS Code (Harmonized Commodity Description and Coding System) is an international commodity coding system developed by the World Customs Organization (WCO). This system consists of 8 or 10 digits, standardizing the names, properties, and classification of goods globally. 

The HS Code is very important in determining tax rates and managing international trade. This code applies to both tangible and intangible goods, based on the code of the container they contain. 

For example: The HS Code of a movie will depend on the HS Code of the hard drive containing that movie.

The meaning of HS Code in import and export    

HS Code is globally standardized, avoiding trade disputes due to local language differences. 

In addition, the HS Code also plays an important role in determining tax rates, managing international trade, and implementing trade agreements. It is the basis for customs agencies, tax authorities, and chambers of commerce to license import and export goods. At the same time, it supports trade statistics and effective goods management. 

For businesses, using the correct HS Code ensures compliance with the law and benefits from trade agreements. On the contrary, incorrect classification can lead to difficulties in delivery, inspection, and legal and financial risks. 

Structure of HS Code 

To look up HS Code, we use the tariff schedule. The tariff schedule consists of 21 parts and is divided into 98 chapters. Specifically: 

21 parts include: 

  • Animals, plants, minerals, plastics, rubber; 
  • Stone products, jewelry, textile products; 
  • Machinery, electrical equipment, vehicles, and tools. 

98 chapters include: 

  • The first 97 chapters classify general goods; 
  • Chapter 98 classifies preferential goods (goods purchased by the Ministry of National Defense). 

Businesses usually only need to pay attention to the first 97 chapters, and only tangible goods are identified in the tariff schedule. 

Heading: includes 2 characters after the chapter, showing the classification of product groups. 

Subheading: includes 2 characters after the group, more detailed below the group. 

Regional Tariff: the last characters are determined by each country. 

Note: Heading, subheading, regional tariff (first 6 digits) are international, while national tariff may vary according to the regulations of each country. 

Vietnam currently applies an 8-digit HS Code for goods. Some other countries may use a 10–12 digit HS Code.

For example: When looking at the HS Code 420211100, we can completely get the following information: 

– 42: Shows Heading – Articles of leather; saddlery and harness; travel goods, handbags, and similar containers; articles of animal gut (other than silkworm gut). 

– 02: Shows Subheading – Trunks, suitcases, vanity cases, briefcases, briefcases, school bags, satchels and similar containers. 

– 11: Shows Regional Tariff – Outer surface of leather or composition leather 

– 10: Shows National tariff – Suitcases or satchels, satchels with maximum dimensions of 56cm x 45cm x 25cm

Rules of looking-up HS Code 

To look up HS Code, we follow 6 rules from rule 1 to rule 6. Only use the following rule when the previous rule cannot be applied.

ssr-logistics-What-is-hs-code-how-to-look-up-hs-code-correctlyRules for looking HS Code up correctly

Rule 1: Chapter notes & Designation name 

The names of heading, subheading, and regional tariff in the HS Code system do not have legal value in classifying goods. They only help to define which type of goods belongs to which section and chapter. Because the names of heading, subheading, and regional tariff cannot cover all products, we need to rely on notes and sub-groups for accurate classification. 

The notes of each chapter are the decisive factor in classifying goods in that chapter and are valid throughout all other rules. Therefore, when looking up the HS Code, it is necessary to carefully check the notes of the relevant section and chapter to determine the product code accurately. 

For example: Determine the HS code of a 230-liter Toshiba refrigerator 

Step 1: Define the area that can be applied to Chapter 84: Nuclear reactors, boilers, machinery, and mechanical appliances; their parts 

Step 2: Read the regional notes (if any) 

Step 3: Read chapter 84 and look at the chapter notes: identify the Toshiba 230 refrigerator as belonging to heading 8418 and the correct HS code is: 84181011  

Rule 2: Unfinished products & Compounds in the same group 

Rule 2a: Unfinished products 

An incomplete item, missing some parts, but still having the same characteristics and uses as the finished product will be classified under the code of the finished product. 

Rule 2b: Compounds in the same group 

This rule applies to products which are mixtures of materials and substances. If a mixture or compound of materials or substances belongs to the same heading, it will be classified in that heading. However, if a mixture or compound consists of materials or substances belonging to different headings, the HS Code will be determined based on the main constituent of the mixture. 

Rule 3: Goods that at first glance appear to be in many groups 

Rule 3a 

Where goods are described in more than one heading, the heading that provides the most specific description shall take precedence over the headings that provide the most general description. 

Rule 3b 

Goods are made up of several products, each of which may belong to several different headings and chapters. Therefore, the classification of the set of products shall be in the product that has the most characteristic character of that set. 

Rule 3c 

When rules 3a or 3b cannot be applied, the goods shall be classified according to Rule 3c. The goods shall be classified in the heading which is the last in order among the headings which are considered for classification. 

Rule 4: Classify according to the goods that are most similar to them 

Compare the goods to be classified with previously classified goods based on factors such as description, characteristics, properties and intended use. After comparison, the goods will be classified into the group of the most similar goods. 

Rule 5: Containers, packaging 

Rule 5a 

Special packaging, containers, or containers of a specific shape, intended to contain a specific set of goods or goods, that are capable of long-term use and are accompanied by the products when sold, shall be classified together with those products. However, this rule does not apply to packaging which has a value or character superior to that of the goods contained therein. 

Rule 5b 

This rule regulates the classification of ordinary packaging used to pack and contain goods when imported together with the goods (plastic bags, carton boxes, etc.). However, this rule does not apply to reusable metal packaging. 

Rule 6: Explain how to classify and compare correctly 

The classification of goods in subheadings of the same heading must fully comply with the content requirements of each heading, by the subheading notes, and by the notes to the relevant chapters. When comparing products between different headings or subheadings, the comparison must be made on the same level. 

Benefits of looking HS Code up correctly 

Looking up the correct HS code brings many important benefits in import and export activities: 

  • Reduce risks and avoid the situation of goods being detained or returned, thereby saving time and costs. 
  • Comply with legal regulations related to import and export and avoid legal consequences such as fines or lawsuits. 
  • Avoid unnecessary fees and fines for violating regulations, thereby minimizing the overall cost of import and export activities. 
  • Support searching for information on legal regulations and fees quickly and accurately. Thereby improving the efficiency in managing and implementing import and export activities.
