Sure. Market access is determined as the average applied tariff rate in the trading partners that country X has. So what you do is you take the trading partners for Honduras, you look at the average tariff rates for the lines of products that Honduras exports to them, and then you make a weighted average for that.
The biggest trading partner for Honduras is the United States, and it has had a free trade agreement with Honduras since 2006. That very much explains why Honduras already has great market access, much better than most other countries.
