A Lagos importer we spoke with last year described his situation simply: "My goods were sitting at Apapa for 11 days. My Form M was approved. My bill of lading was clean. But the bank still had not released the LC." He eventually paid a premium to a non-bank financer to move his cargo. That story is not unusual. It is the default experience for most Nigerian SME importers.
We built Trade Lenda because we wanted to understand that delay precisely — not just feel it, but map it step by step. What we found when we traced the 28-to-35-day bank LC cycle is that the bottleneck is not one thing. It is a sequence of verification steps, each of which adds days, and none of which has been connected to the data that already exists in the Nigerian customs system.
The Anatomy of a 30-Day Wait
When a Nigerian importer applies for an LC through a commercial bank, the process looks roughly like this on paper: submit documents, bank reviews, correspondent bank confirmation, CBN FX allocation, funds disbursed. That is four steps. In practice, each step fragments into sub-steps that can each stall independently.
Step one: document submission and internal review
A standard import LC application requires a commercial invoice, proforma invoice, bill of lading, packing list, Form M, and evidence of CBN registration for the importing entity. Most importers take 2–4 days to assemble these, often because the proforma from their overseas supplier came in late or the Form M reference number needs to be cross-checked. Once submitted, the bank's trade desk assigns the application to a credit analyst who reviews the applicant's credit history, trade history, and the specific commodity being imported — some commodity categories attract elevated scrutiny. This internal review alone takes 5–8 business days at most commercial banks.
Step two: correspondent bank verification
Nigeria does not have direct settlement relationships with every supplier country. For an import from a Chinese manufacturer, for example, the Nigerian bank typically routes through a correspondent bank — often in London, New York, or Singapore — to confirm the LC terms and issue the instrument. That correspondent relationship introduces a 4–7 day window, including time-zone lag and the correspondent bank's own compliance checks. If the Nigerian bank has a thin relationship with a particular correspondent, or if the commodity triggers sanctions screening, this step extends further.
Step three: CBN FX allocation
Post the 2023 FX window unification, importers must still obtain FX through the official window for valid imports. The CBN processes Form M-linked FX requests through the banking system, and allocation queues can add 5–12 days depending on demand pressure and whether the commodity falls under the CBN's priority list. Electronics, industrial machinery, and raw materials typically move faster than finished consumer goods, but even priority categories can stall when the official window is under pressure.
Step four: internal compliance sign-off
Before funds are released, most banks require a compliance officer sign-off that is separate from the trade desk review. This is where Know Your Customer (KYC) re-verification happens, especially if the importer has not done a transaction in the past 6 months. Add 2–4 days for this, and another 1–2 for the actual disbursement processing.
Add these up honestly: 5 days minimum (if everything runs perfectly) to 35 days if any one step stalls. The median, based on conversations with importers in the Alaba International electronics corridor and the Balogun textile market, is around 22–28 days. That is the real number.
What the Bank Is Actually Trying to Verify
It is worth being clear about why banks are slow here — the 30-day cycle is not bureaucratic negligence. Banks are trying to answer three questions: Is this importer creditworthy? Is this shipment legitimate? Will the FX exposure be covered? Each of those questions requires information that the bank has to gather manually, because the data infrastructure connecting Nigerian customs, BVN databases, and trade history has not been integrated into bank underwriting systems.
When a bank analyst opens an LC application, they pull the importer's credit history from the bank's internal records, check for any CBN watchlist flags, and then manually review the shipping documents to assess whether the cargo matches the declared commodity and value. The NCS Single Window system contains rich customs clearance data for every registered importer — shipment frequency, commodity categories, clearance times, duty payments — but commercial banks do not have automated access to that data stream. So analysts review it manually, which means slowly.
This is precisely the gap we are working in. The data to score a trade accurately is not missing. It already exists. It lives in NCS records, in CBN Form M databases, in shipping manifest registries. What was missing was a system that reads all of it simultaneously and produces a risk signal fast enough to support a 48-hour decision.
The Cost of Waiting — Beyond the Obvious
The direct cost of a 30-day LC wait is storage and demurrage. At Apapa, demurrage on a 20-foot container starts accumulating after a free period of typically 5–7 days after vessel arrival. At current port rates, a single 20-foot container held for 21 days past the free period can accumulate ₦180,000–₦350,000 in demurrage charges depending on the terminal. For a mid-size importer running multiple containers, this figure multiplies quickly.
But the less visible cost is the opportunity cost on the supplier side. Most overseas suppliers — particularly Chinese manufacturers supplying electronics, garments, or industrial components to Nigeria — operate on payment terms of net-30 or letter of credit at sight. When an importer cannot confirm an LC within 10 days of a proforma invoice, suppliers either push the order back, reallocate production capacity to another buyer, or quote a higher price on the next order to compensate for the uncertainty. Nigerian importers who can pay quickly consistently get better FOB prices and preferred allocation during high-demand periods. The 30-day bank cycle is not just expensive — it erodes the importer's negotiating position in the supplier relationship.
Where the 48-Hour Model Fits — and Where It Does Not
We want to be direct about what Trade Lenda does and what it does not replace. We are not a substitute for the banking system, and we are not saying every importer should move away from bank LCs entirely. For large importers — say, a company running ₦2–5 billion in annual import value — a bank LC remains the right instrument for many transactions, especially where the overseas supplier specifically requires an LC issued by a regulated Nigerian bank for financing purposes.
Where Trade Lenda operates is the gap between the importer's invoice date and the point at which bank capital would arrive. We advance working capital against a verified import invoice so goods can clear port and sales can begin, while the bank process continues in parallel or the importer manages the repayment from trade revenue. For SME importers in the ₦5M–₦500M invoice range — which covers the majority of active Lagos traders — that gap is where cash flow breaks down.
We also do not claim to solve every delay. If an importer has undisclosed compliance issues, inconsistent NCS records, or a buyer with no verifiable payment history, our model will flag the risk and we will not advance capital into a trade we cannot underwrite confidently. Speed without accuracy is just fast lending into bad trades. That is not what we are building.
What We Changed in the Underwriting Process
The core change is not that we removed steps. We compressed them by connecting the data sources that bank analysts check manually. When an importer submits a trade application to Trade Lenda, our system immediately pulls their NCS clearance history — checking shipment frequency, commodity consistency, duty payment record, and average clearance time. That alone answers roughly 40% of the questions a bank analyst would spend days investigating.
We then cross-reference the shipment manifest against commodity price benchmarks and route risk data to assess whether the invoice value is consistent with market pricing for the commodity category and origin country. A ₦42M invoice for 500 units of a specific industrial component from a Guangzhou supplier should align within a reasonable band of current FOB prices for that HS code. If the declared value is significantly off-band, that is a flag — either a valuation error or something that needs human review before we advance capital.
Finally, we run a buyer reliability check for export transactions, and a basic counterparty check for import transactions against our database of overseas supplier payment patterns in West African trade corridors.
The output of all this is a risk score and a set of flags that a human underwriter reviews. The underwriter is not starting from scratch — they are reviewing an AI-generated summary that has already done the data assembly. That is what makes same-business-day decisions possible. Not algorithmic lending without human judgment, but human judgment operating on better-organized information.
What Comes Next for Nigerian Trade Finance
The 30-day wait is not permanent. Nigerian banks are themselves investing in trade finance technology, and the NCS Single Window has improved data quality significantly over the past two years. At some point, the gap between bank underwriting speed and market reality will close further. Our view is that the infrastructure for faster trade finance is being built now, and that alternative lenders like Trade Lenda are both filling the current gap and demonstrating what the data-connected model looks like at production scale.
For importers reading this: the 28-day wait is a solvable problem. It is not the cost of doing business — it is the cost of an information gap that technology can close. We built Trade Lenda because we believe Nigerian SMEs should not be paying demurrage charges and losing supplier relationships because of a processing queue that moves at 1995 speeds on data that is already available in 2025.
