Realize timely implementation of duty-free and quota-free market access on a lasting basis for all least developed countries, consistent with World Trade Organization decisions, including by ensuring that preferential rules of origin applicable to imports from least developed countries are transparent and simple, and contribute to facilitating market access

In simple words: Developed countries should allow products from the poorest/least developed countries to enter their markets without charging import duties (taxes) on them. There should also be no quotas, which limit the amount that can be imported. This duty-free, quota-free access should not be temporary, but lasting/permanent. It should happen in a timely manner, not delayed.
