These components form a basic tariff system but there are much more complex versions in existence too.

The basic tariff is Dh3, during the day and evening base fare is at Dh4.

But basic tariff levies on crafters and artisans and farmers will go up in a year, and then more in another year.

The basic tariff is calculated on the basis of economic costs according to a methodology defined at the national level by CRA (Law 287 of 2004).

So, while the tariff rate is generally the most an interstate carrier can charge, most movers charge less - up to 50 percent less - making the basic tariff more a cap than a guide.

It is unacceptable because it rejects Parliament's initial proposal to limit the next stage of liberalisation to 150g and four times the basic tariff, and yet does not give any guarantee that a high level of social cohesion will be maintained.
