I am looking for anyone who can help answering questions such as determining the distribution prices and quantity range as well as sharing their experience in import/export regulations of other countries in the world.
Do in country market research, analysis and most importantly user testing on branding, pricing, acceptability, competition etc within that country on a small sample size. That's the best method
For qality range, import and export issues most countries differ. Large quantities, I'd consult a US based distributor who may have clearances already to your destination country and align with them. Small quantities I'd recommend connecting with a few retailers in country, they are best to advise and you can co-create a strategy that they are likely to support and they will best show you the market gaps based on their experience
Good luck
