There are multiple formats in which the information sharing happens by multiple institutes and industry groups.

One-day or 2-day seminars, which provide an overview of the high-level activities involved in export businesses
3-month certification programs which can be done virtual classes(online) or long-distance (material will shipped to your address)
If you are serious about getting into the business of exports, I suggest that some rigour is required and hence option 2 is recommended (specifically online classes are better).

If you just need to know the basics if you are entering the industry to familiarise yourself with the terminology and processes at a high-level, then short-duration seminars are perfectly suited for you and the cost is also relatively smaller.

Here are some of the institutes who provide such training / seminars / certifications:
