Customs Procedures
Lesson 3 of 4
25 min

A container like those in the photograph may hold goods that a Rwandan trader ordered weeks ago. Before the trader can sell a single carton, the goods must be cleared: declared, checked, taxed and released by customs. Since 2012 this has been done through the Rwanda Electronic Single Window (ReSW), an online system in which the clearing agent, customs and the other government agencies all handle the same declaration. RRA reports that it cut the average time to clear imports from 2 days 18 hours to 1 day 15 hours.
Definition
Customs clearance: the process of meeting all customs requirements so that goods may be released: declaring them, presenting documents, inspection where needed and paying duties and taxes.
Rwanda Electronic Single Window (ReSW): the online platform, launched in 2012, through which traders submit one declaration that covers customs and the other agencies’ requirements.
Clearing agent (customs agent): a company licensed by the Commissioner for Customs Services to declare and clear goods on behalf of importers and exporters.
| Document | Issued by | What it shows |
|---|---|---|
| Commercial invoice (original) | the seller | the goods, quantities, prices and total value: the starting point for the customs value |
| Packing list | the seller | what is in each package, with weights and marks, so customs can check the goods |
| Bill of lading (sea) or airway bill (air) | the shipping company or airline | that the goods were shipped, by whom and to whom; it is also the receipt and contract for carriage |
| Freight and insurance invoices | the transporter and the insurer | the cost of transport and insurance, if not on the commercial invoice, to find the CIF value |
| Certificate of origin | an authority in the exporting country | where the goods were made, so that EAC or COMESA goods can enter duty-free |
| Import permit or licence | the agency concerned | permission to import restricted goods |
| Other certificates | regulators such as standards, food and drug, or plant and animal health agencies | that goods such as food, medicines, chemicals and cosmetics meet the rules |
The clearing agent enters these details in the customs declaration on ReSW and attaches scanned copies. RRA requires goods worth more than Frw 500,000 to be declared through a licensed clearing agent.
Definition
Commercial invoice: the seller’s bill to the buyer, listing the goods sold, their quantities, unit prices and total.
Packing list: a list of the contents of each package in a consignment, with weights and identifying marks.
Bill of lading: a document issued by a shipping company when goods are loaded on a ship; it is a receipt for the goods, evidence of the contract of carriage and a document of title. An airway bill does the same job for goods sent by air.
Certificate of origin: a document certifying the country in which goods were produced.
Tip
Memory hook: “A-D-A-P-C-R-A”. Arrive, Declare, Assess, Pay, Channel, Release, Audit. In an exam, state each step and who does it: the transporter reports, the agent declares, the system assesses, the importer pays, customs verifies and releases.
Worked example 1: the missing document
A trader in Rubavu imports tinned tomatoes from a country outside the EAC by sea through the port of Dar es Salaam. Her agent attaches the commercial invoice, the packing list and an EAC certificate of origin. Which document is missing, and which one does not help her?
Missing: the bill of lading, because the goods came by sea from outside the EAC. As a food, the tomatoes may also need a certificate from the food safety regulator.
Not helpful: an EAC certificate of origin can only be issued for goods made in the EAC; tomatoes from outside the EAC pay the common external tariff. The trader is illustrative.
Worked example 2: how much time did the Single Window save?
RRA reports that average import clearance fell from 2 days 18 hours to 1 day 15 hours. Find the saving as a percentage.
Convert to hours: hours and hours.
Saving: hours, and RRA rounds this to a 40% reduction.
Interpret. For a trader paying a lorry and driver by the day, more than a day saved on every consignment is a real cost saving, passed on in lower prices.
Warning
Common mistakes. (1) Putting payment last: in Rwanda the duties are paid after assessment and before release. (2) Thinking the red channel means the trader did something wrong: it means the consignment was selected for physical inspection by risk rules. (3) Forgetting the audit: blue-channel goods are released quickly but can be audited afterwards.
