Hi,
You should have access to the price and the category thanks to the variable $template.
The HikaMarket "copy" is using the HikaShop import helper with the function "copyProduct" (that's why it's the same trigger).
If you take a look at the function "_insertPrices" of the HikaShop import helper you will see that it will load the prices from the template if the $product object does not have some.
