The best free resource to gain access to international trade related data is : ITC Trade Map.
Here is a link to it : https://www.trademap.org/Index.aspx
In this you can search monthly, quarterly and yearly time series data of import/export and international goods trade between various countries that disseminate this data publicly. You can search it by the HS Code of your product.
Hope this helps.
