Royal Mail and some other couriers require Tariff Code (Harmonized or HS code) and Country of Manufacture attributes for international shipments. These can be easily imported for your inventory items using Import Data.
1. You need to prepare a CSV file containing all the required data. If you don't have a CSV file with all your SKUs, then you can easily export it from Dashboards > Query Data > Stock Items (no levels). You can delete all other columns except for SKU. Then, add HSTariffCode (Tariff Code*) and ManufactureCountryCode (Country of Manufacture**) columns to your file. You can use a different name for these columns if you wish, as you can map them in the system afterwards.
* You can check Tariff Codes using the following link: https://www.trade-tariff.service.gov.uk/trade-tariff/sections
Royal Mail requires 6 digit code. If you import full harmonized code (8 characters), then Linnworks will truncate it to 6 characters.
** Country of Manufacture needs to contain an ISO alpha-2 or ISO alpha-3 code for Royal Mail. For a full list of ISO alpha-2 and alpha-3 codes, please refer to this link: http://www.nationsonline.org/oneworld/country_code_list.htm
2. You can create a new import in Settings > Import Data > Import Now. For importing new extended properties you need to use the Inventory Import. Columns that contain your attributes need to be mapped with 'Item Extended Property' variable from the drop-down menu. The name of the header will be the name of your property, and the Property type needs to be Attribute (these will be set automatically). Once imported, these properties will appear on your stock items in the Extended Properties tab.
3. Once the properties have been added to your inventory items, you now need to link these properties with the correct attributes in your shipping integration. This can be done by clicking Properties in the courier integration screen (Linnworks.net > Shipping > Integrations > Royal Mail > Properties).
Under the Item Extended Property column select the name of the property that has been imported or keep it as it is, if the same names have been used:
