1. Mismatched documentation
When the commercial invoice, packing list and bill of lading don't agree on quantities, values or descriptions, customs has grounds to hold the shipment for clarification. Having your supplier and forwarder reconcile these documents before the goods ship is the single most effective way to avoid this.
2. Incorrect HS classification
Misclassifying goods can mean paying the wrong duty rate, missing a permit requirement tied to the correct classification, or triggering a reassessment that delays release. For anything ambiguous or high-value, RRA's advance ruling system lets you confirm classification before you ship — our guide to HS codes in Rwanda covers this in full.
3. Missing product-specific permits
Pharmaceuticals, agricultural products and certain other categories need permits beyond the standard document set. Discovering this requirement only once the goods have arrived is one of the most common — and most avoidable — causes of a held shipment.
4. Using an unlicensed or unverified clearing agent
Since a licensed clearing agent is a legal requirement for every import, the quality of that agent directly shapes how smoothly your shipment moves. Verifying a RURA licence, RWAFFA membership and CCFL-certified staff before committing cargo to an agent avoids a wide range of downstream problems.
5. Not preparing documentation before arrival
Waiting until a shipment reaches the border to start assembling paperwork guarantees a slower clearance than lodging the declaration in advance through the Electronic Single Window. This single habit — preparation before arrival rather than after — is behind most of the delays covered in this list.
6. Underestimating total landed cost
Freight cost alone isn't the total cost of an import. Duty, VAT, withholding tax, clearing agent fees and last-mile delivery all add to the figure, and businesses that budget only for freight are routinely surprised by the full landed cost. Our guide to shipping costs to Rwanda breaks down every component.
7. Choosing the wrong shipping mode for the cargo
Air freight for genuinely urgent, high-value or perishable goods; sea or road freight for bulk, non-urgent cargo. Defaulting to one mode regardless of what's actually being shipped either overpays for speed you don't need or risks a timeline that doesn't match the cargo's urgency.
8. Overlooking regulated-goods requirements specific to the product
Electronics with radio functionality need RURA type approval. Machinery may qualify for investor duty exemptions that require a separate application. Agricultural exports need phytosanitary certification. Each product category can carry its own requirement beyond the general import process, and assuming a generic process covers everything is a common error.
9. Treating a first shipment on a new route the same as an established one
A new supplier, a new corridor, or a new destination market all carry more uncertainty than a route your business has used repeatedly. Building extra time and diligence into a first shipment — rather than assuming it will go exactly as smoothly as a well-established one — avoids unnecessary surprises.
10. Not building a relationship with a single accountable logistics partner
Coordinating freight, customs and delivery across separate, uncoordinated vendors adds handoff risk at every point. A single freight forwarding and clearing partner who handles the whole journey, and who knows your business's typical cargo and requirements, catches problems earlier and resolves them faster than a fragmented supply chain with no single point of accountability.
