I have suppliers for nearly all the reagents. but there are some problems,
1- as they all are medium to small manufacturers they don't sell online at international level, at nation or state level they provide delivery services.
2- each manufacturer has a small catalogue so you have to order from multiple sellers.
solutions:-
1- the medium level manufacturers contain all the pharma reagents and supply internationally as i remember they all have import-export license.
2- as these chemicals (restricted at most of the countries) are legal here and they can be exported as something else without any problem with customs on both sides.
3- they are cheap af nearly same as chinese ones in quality and price.
still i would prefer chinese manufacturers over mine for international level as the chinese one are seasoned.
still if you want i would love to post their names, addresses, contacts, with products they have. (there are multiple suppliers for same product with different prices).
i have purchased from few of them in past and i can trust them.
