When importing or exporting USB flash drives in the United States you will want to use this Harmonization Code to help with customs paperwork.
The Harmonization Code is tariff nomenclature for internationally trade which defines names and numbers assigned to traded products. The HS Code System came into effect in 1988 and has since been developed and maintained by the World Customs Organization (WCO), based in Brussels, Belgium. There are over 200 countries which participate in this program.
The HS Code for a USB flash drive is: 8523.51.0000
In the event your freight forwarder or delivery service tells you that an ECCN is needed to ship USB flash drives and is required to complete the Automated Export System (AES) or other documentation then please give them the above information and it should all work out.
ECCN stands for Export Control Classification Number. An ECCN is an alpha-numeric classification used in the Commerce Control List to identify items for export control purposes.
