Sourcing competitor suppliers

Hi All,

Dont know if this is the right place to post but:
I own a webshop in apparel and have had some trouble with finding the right suppliers for a new product on alibaba, without spending too much on research & development and shooting arrows hopefully landing on the right supplier I found out the following:

Apperantly all import data in the USA is public so I thought I'd use that to search for my competitors' suppliers, I have checked out this website:

https://portexaminer.com/

Though the data on this website seems outdated,

Then there are a few subscription based tools that seem to do the same, does anybody know one of these and can you share your experience?

• https://www.importgenius.com/ (starts at 99 a month)
• https://panjiva.com/ (starts at 300 a month)
• https://www.usaimportdata.com/ (seems a bit dodgy and cant find the pricing)

Id be using it to source for one product, though if I purchase a subscription I'd probably use it to source for more products I want to sell in the future..

If you have other sourcing strategies that work well for you feel free to mention!

Great Idea. I've also pondered how to find out where competitors are getting their products made.
Lots of this "spending too much on research & development and shooting arrows hopefully landing on the right supplier"..
