Transit bonds and the RCTG regional guarantee

Last checked 24 October 2026 · 8 sources

Short answer

A customs transit bond is a guarantee that the duties on goods crossing a country will be paid if the goods are diverted. The COMESA Regional Customs Transit Guarantee, known as RCTG-CARNET, lets one guarantee cover the whole journey through member states 1,2. COMESA says implementation started in 2012 1. Inside the EAC, TRA says warehoused goods under the Single Customs Territory move under the Electronic Cargo Tracking System or the RCTG 5.

Why transit goods need a bond

The EAC Customs Management Act defines transit as the movement of goods imported from abroad through one or more Partner States to a foreign destination 4. Transit goods not re-exported within the Commissioner's time limit are treated as prohibited or restricted goods (section 20(2)) 4. Sections 106 to 109 let the Commissioner require security and set out rules on sureties and the enforcement of bonds 4. The 2025 amendment replaced the word surety with bond in section 108(2)(d) 8.

COMESA says customs bond guarantees protect governments. If transit goods are diverted for use in the transit country, the government can recover the duties and taxes from the guarantor 1.

How the RCTG Carnet works

The UNESCAP Cross-Border Paperless Trade Database, updated on 5 June 2024, says one RCTG guarantee covers the duties and taxes at risk for the whole transit. The Carnet serves as a bond or guarantee exemption certificate in every member state the goods pass through 2. Goods travel with a customs transit declaration and all carriers in transit must be licensed 2.

The same record says the online system manages bonds, clearing and forwarding agents, guarantors, T1 entries and Carnets. It links to national customs systems to receive transit declarations in real time and records bond cancellation when the Carnet is acquitted 2. It lists insurance companies, banks and clearing and forwarding agents among the entities taking part, and keeps guarantor data on insurers 2.

It said the Comesa bond rate was cut from 0.75 percent to 0.5 percent, against a Uganda national bond rate of 0.25 percent 3. It said the scheme had earned over $600,000 in premium income from sureties covering 194 clearing and forwarding agents 3.

The UNESCAP record gives a cost saving of 15% in one field and 10 to 15 percent in its text 2. It names unreliable internet and delays in buying equipment in some member states as challenges 2.
