International Duties and HS Codes

[WesternWishMoss]

I have international duties and taxes enabled and it is displaying at checkout. Looking into HS codes for various countries, it looks like for the same kind of product the full HS code and the duty amount differs depending on the country. For example, the action figure or dolls subcategory within the Toys category in Canada has a full HS code of 9503009011 and a duty rate of 0%. But for the UK, the full HS code is 9503002190 and a duty rate of 4%. Shopify allows the entry of just one HS code per product, and that is just the shortened version of 950300. Because the full HS codes for all countries aren't assigned to a product, this means that duties aren't being accurately calculated at checkout. Instead of calculating a 4% duty for the UK, it shows as 0%. The necessary funds to purchase the shipping label won't be collected, since the correct duties may not be collected at checkout from the customer depending on their country. Or is there something about the HS codes that I'm not understanding?

I see that there are integrations such as ClickShip and Easyship. Do those accurately display duties and taxes on the Shopify checkout page? My Shopify store has a marketplace setup where sellers list their items for sale on a third party app, then the items populate on the Shopify store. So it is important for the sellers to have Shopify collect the proper duties and taxes, as well as for the sellers to know the proper HS code when they visit usps.com or ups.com to purchase a shipping label.
