Best practice is that all items in eCommerce shipments should have HS Tariff Codes applied. They help with faster processing of shipments, and more accurate calculation of taxes and duties payable in the destination country.
Many countries have made it compulsory to declare HS Tariff Codes, and will reject parcels if you fail to declare them.
Add the HS Tariff Codes to your products in Shopify and they'll automatically be included for any orders.
This Shopify help article explains how to update HS Tariff Codes individually and in bulk: https://help.shopify.com/en/manual/shipping/shopify-shipping/hs-codes
You also need to supply the "Country of Origin" for your products. This must be the country the item was manufactured in, not the country you are selling the item from.
For example Even though your store is in Australia, if your goods were made in China then 'China' would be your Country of Origin.
If all of your products are manufactured in the same country, you can add that as a default in your carrier settings in our app. If you use both MyPost and eParcel, you will need to update it in both carriers.
Click on CARRIERS in the top menu of our app.
Click on the blue pencil icon beside your carrier.
Click on DEFAULT SETTINGS.
Scroll down to the Country of Origin and enter the relevant country in the field provided.
If your products are manufactured in various countries, you should add the Country of Origin to the Product in Shopify at the same time as you are adding the HS Tariff Code.
If adding the codes in bulk, when selecting the "Harmonised system code" column, you can also select the Country of origin column to appear too, then you can update both in bulk.
Our app has a handy feature that will warn you if the HS Tariff Code or Country of Origin is missing for any international orders:
Please note: These red warnings are just that, a warning. They are not an error.
If you see any of these warnings, you have a few options.
Update the Product data in your Shopify admin, return to our app and refresh the order data, by clicking the refresh icon (shown below):
You can also override the Product data in our app (Doesn't update back to Shopify), by clicking the pencil icon (shown below), and changing values.
Don't want to see the warnings on your International orders? You can remove the Tariff Code and COO display by editing the display settings for the order grid in our app.
