| Harmonized (HAR) |
These are products intended for use in Europe that fall under the Harmonization Documents. These items must be manufactured within a member country there are no exceptions. For this reason these carry the name and/or file numbers of the producing party. Products that comply with this are P/N Series 1900 through 1906 and P/N Series 1915 through 1925. |
