It looks like you're attempting to obtain import/export data for a specific product for free. Importer/exporters, HS Codes, trade volume, and pricing are some of the information you seek. While you ae looking for all of the appropriate information, I'm afraid it'll be difficult for you to get the information you're searching for free. There are a few websites that will give you some of the information you're looking for, but most of it will be out-of-date by at least two years. If you want my advice, I suggest you contact the relevant customs authorities in each country. You need to look into the availability of data and see if it's feasible. If not, you must decide how much you are prepared to spend on knowledge. If the cost is acceptable, you should pay for it and obtain the information you require.
