HS Code for Power Supply 

With the increase in electronic users and rapid innovation of technology, the demand for power supply worldwide is increasing steadily. In order to facilitate the power supply in international trade, the HS code comes in the first row of requirements. The declaration of the HS code for power supply is required to smooth the customs process. In this article, we will explain and learn more about the HS code for power supply, the leading exporting and importing countries of power supply, along with the quick method to find the accurate HS code for power supply. 

What is a Power Supply, and how has it become an important piece of equipment?

Power Supply Unit (PSU) or power supply is an electronic equipment that is specifically made for converting the power energy supply to devices such as a computer, laptop, tablet, or a handphone. This equipment has a role to transform high voltage current, also known as AC, into direct current (DC) required by modern devices. This process is crucial to stabilize the power input and prevent different voltages and power currents, which can harm the devices. There are several important functions of a power supply, as follows: 

• Reducing noise and fluctuations of the power input into the computer, which can mostly cause errors if there is instability of the power supply. 
• Ensuring the consistency of power input in order to ease the electrical stress on components. Power supply will help the device last longer due to damage to the hardware from the unstable power supply. 
• The existence of a power supply will support the operation of the critical facilities, such as healthcare, education, defence, and other industries. The fluctuation of the power supply will affect the safety and security in a country. 
• PSU can also be formed as a power backup, such as a power bank and an uninterruptible power supply (UPS). Using this equipment will help you to find the 

What is the HS Code for Power Supply? 

As explained in the introduction, the HS code is the universal requirement in international trade. The 6-digit code from the World Customs Organization (WCO) has become the standard before moving the products to another country. A declaration of HS code is pivotal to guarantee that the products or goods will get customs clearance easily. If there are mistakes in the declaration of HS code, there are consequences, which mainly include fines and bad reviews, or affect the credibility of the exporters or importers. 

In the global trade scheme, the HS code for power supply falls under Chapter 85. However, that chapter covers a wide selection of electrical equipment, including smartphones, domestic electronic appliances, video/sound recording apparatus, cables, etc. Thus, you may want to independently select which one can be categorized as a power supply. Here are some popular or common examples of 6-digit HS codes for power supply. 

You might also need to add two more digits of the HS code to classify more attributes, such as materials or the amount of capacity. For example, primary cells or batteries made of Mercuric Oxide have HS Code 8506.30, meanwhile the ones made of Lithium are classified with HS Code 8506.50. Same with converters/transformers/inverters, ones with power handling capacity under 650 kVA have a different 6-digit HS code compared to the ones with a capacity range above 650 kVA, yet still under 10,000 kVA. 

Key takes on determining the correct HS code for the power supply

To prevent disputes or problems with customs, ensure you note some key traits of power supply products that can influence the classification or final HS code. Generally, customs will consider the following things to determine the correct HS code. 

• Power rating
• Voltage
• Storage existence
• Usage 
• Programmable or unconfigurable
• Separate parts or integrated 

As an anticipation, do attach technical information to fasten the process and reduce any potential hassles with customs officers that often lead to penalties or rejections. You may also need to provide certification to guarantee the safety or energy efficiency proof. Some countries or sovereign nations may ask you for this, such as the  EU, USA, China, India, etc. 

The top 5 biggest power supply unit exporters and importers

Now, who are the biggest actors in the global power supply market? UN Comtrade has published 2024 data. When we narrowed it down to HS Code 850440, which is used to classify static converters, we had this list of top exporters.

Are there any additional tariffs for exporting products under HS code 85044060 from Thailand to the United States? 

Yes, there are additional tariffs for exporting a static converter from Thailand to the United States. This is because the US Department of Commerce has determined antidumping and countervailing duties for crystalline photovoltaic cells from Thailand. This includes the products under HS code 85044060. Thus, the exporters from Thailand might face the dumping margins of 111.45% to 202.9%. On the other hand, the United States is also conducting an antidumping investigation into refrigerator-freezers from Thailand which margin of 165.47% and it can affect the final tariff rate. Moreover, the United States also initiated the antidumping and countervailing duty for epoxy resins from Thailand, which is also under this code. The margin, ranging from 143.73% to 176.34% that have a huge impact on the final determination of tariff rate. 

Are there any exemptions or reductions available for the additional tariffs on HS code 85044060?

There are no exemptions or reduced tariff rates for exporting products under HS code 85044060 from Thailand to the United States. From all of sources, the antidumping for crystalline photovoltaic cells under this code is not subject to special treatment, including exemptions, or reduced tariff rate before entering the United States territory. Meanwhile, the general tariff rates for static converters to be exported to the United States adhere to the Most Favored Nations (MFN) regime, which means this tariff applies not only to Thai products, but also to all of the countries around the world. Here is the table summary of the tariff rate from the United States agency. 

What are the specific requirements for exporting products under HS code 85044060 from Thailand to the United States?

There is no specific requirement for exporting products under the HS code 85044060 from Thailand to the United States. Thus, the general trade requirements are applied for the exportation of static converters from Thailand to the United States, including the exemption of a certificate of origin for information technology imports based on the WTO Information Technology Agreement. Meanwhile, Thailand is eliminating from using electrical and electronic equipment from certain compliance requirements regarding hazardous substances. From the United States perspective, it is focused specifically on energy efficiency, but does not specify the requirements for export. Here is the list of requirement types. 

Conclusion

As we live in a technology disruption era, it is hard not to live with electrical apparatus. Power supply itself is one of the backbones in this industry, and it is only natural for global trade actors to be lured into this market. Similar to other commodities, power supply has its own HS code, generally falling under Chapter 85 per the WCO archive. However, as that chapter covers almost all electrical machines, appliances, and apparatus, it requires a good understanding of specific power supply products you intend to trade (export/import).
