Sudan: customs exchange rate adjustment raises import costs; Importers Chamber warns of possible sales halt

## What happened
The Sudanese government has increased the official exchange rate used to calculate import duties and other customs charges, according to statements by the National Chamber of Importers through its member Qasim Al-Siddiq to Sudan Horizon media. If confirmed, the measure would significantly raise the cost of imported goods and could force traders to temporarily suspend sales due to the difficulty of passing on the increase to final prices immediately. So far, no official decree detailing the new rate or calculation methodology has been published.

## Context
Sudan faces a severe economic crisis, with high inflation and devaluation of its local currency. The customs exchange rate is a mechanism the state uses to adjust fiscal revenue and control imports. In this context, any change directly impacts the cost of imported goods and operator profitability. The lack of official dissemination of specific details about the new rate adds uncertainty to importers' operational and financial planning.
