The Harmonized System is an international numbering system for products and includes 5,000 commodity groups, each containing a six-digit code. The system encompasses over 98 percent of the products used in international trade. The code can be broken down into three parts, with the first two digits identifying the good?s ?chapter,? the next two digits signifying the product’s group and the last two digits identifying specific product qualities.
The first 6 digits of the harmonized system are universal – the numbers breakdown after that based on the country you are shipping to.
