The order of calculation
- CIF value. Goods value on the supplier invoice, plus international freight, plus insurance. This is the value customs works from.
- Customs duty. CIF × the duty rate for your tariff line. Liberia applies the ECOWAS Common External Tariff, so most goods fall into one of a small number of bands — but the band depends on the specific line, not the chapter, and exemptions exist.
- ECOWAS Trade Levy (ETL). A small percentage of CIF, commonly 0.5%, on goods from outside the ECOWAS region.
- Inspection / destination inspection fee. A percentage of CIF with a minimum charge. The minimum matters most on small shipments, where it can dwarf the percentage.
- Cargo Tracking Note (CTN / ECTN). Charged per container or per consignment, depending on container size. It is a document cost, not a tax, but it is unavoidable and easy to forget.
- Goods and Services Tax (GST) at 13%. Charged on CIF + customs duty + ECOWAS Trade Levy + applicable excise. GST on imports is a cost you finance up front even if you can recover it later.
- Clearing and delivery. Broker fee, terminal and port handling, storage, documentation, bank charges and inland trucking from the Freeport of Monrovia to your warehouse.
Where importers get caught
- Treating GST as if it applied to the invoice value. It applies after duty and levies, so it is always larger than expected.
- Ignoring inspection minimums. On a US$4,000 shipment, a fee with a US$190 floor is a real percentage of your margin.
- Forgetting the CTN. It is charged before arrival and often paid by a third party who invoices later.
- Storage creep. Every day of demurrage or port storage lands on the same shipment and needs to be added back to landed cost.
- Assuming a rate from a six-digit HS code. The Liberian national extension, and any exemption, decide the actual rate.
A worked example
A trader imports one 20-foot container of housewares. Goods value US$18,000, ocean freight US$2,400, insurance US$180. CIF is US$20,580. At a 10% duty rate, duty is US$2,058. ETL at 0.5% of CIF adds US$102.90. An inspection fee of 1.2% of CIF is US$246.96, above the US$190 minimum, so the percentage applies. The CTN for a 20-foot container adds US$185.
GST at 13% on customs value plus duty plus ETL — US$22,740.90 — is US$2,956.32. Broker, terminal, documentation and trucking of US$1,450 bring total landed cost to roughly US$27,579. That is 53% above the supplier invoice, and 35% above invoice plus freight. An importer who priced from US$20,400 has already lost the margin.
Verify before you commit
Cardinal Toolworks does not publish live rates, and no honest tool should. Rates change, and origin and exemptions change them again. Check your tariff line with the Liberia Revenue Authority or your licensed broker, record the source and the date, and put those figures into the calculator. TrueCost keeps that verification record on the report.
