General Info:

The first 6 digits of a Harmonized System (HS) code are universal and standardized worldwide!
- Numbers after the first 6 digits will be dependent on the country you are importing into.
Country of Origin: THIS IS IMPORTANT!!! Do not list USA because this is not the country of origin where the said product was manufactured in.
- For US based GOM: Try to list Korea if you can because even though some products are manufactured in China, country specific surcharges can be applied and products manufactured in China is one of the said countries because of our current government.
Keychains do not have a specific HS code dedicated to it, the HS code is dependent on the material of keychains. Read for detailed info.
- For plush keychains, recommend using the HS code for toys instead of the one mentioned in the article. Metals usually carry duties.
Random tidbits about certain codes:
