Exporting and importing products with international shipping come with extra steps.

Harmonized System (HS) codes are commodity codes used to classify international inventory being shipped. It is a standardized system of classifying and identifying shipments around the world. Utilized by customs authorities across the globe, HS codes identify products when assessing duties and taxes as well as for gathering statistics. They are recognized in 98% of world trade.
​
Companies use an HS number to reference the classification with their customers, vendors and anyone outside of the U.S. HS codes are an integral part of international trade.
