What an assessment is actually checking
Once cargo is declared, Nigeria Customs Service assesses the duty and charges payable and decides how the consignment will be treated: released on the documents, or held for a closer look. To do that, the assessment reads the declaration against the commercial invoice, packing list, bill of lading and the import documentation opened through the importer's bank before shipment.
An assessment does not stall because it is slow by nature. It stalls when something in that reading does not fit: a value that looks low for the goods, a classification that does not match the description, a quantity that differs between two documents, or a regulated product without its certificate. Each of those becomes a query, and each query waits for an answer.
Valuation queries: when the declared value is doubted
Duty is calculated on value, so the declared value attracts close attention. Where the invoice price looks out of line with comparable goods, the assessment may be held while the value is reviewed, and the importer may be asked to support it with further evidence such as the purchase contract, proof of payment, supplier price lists or freight and insurance documents.
The practical defence is an invoice that reflects the real transaction and is supported by documents that tell the same story. Discounts, bundled pricing, free samples and goods shipped under a wider supply contract should be explained on the documents before shipment, not argued after the cargo lands.
Classification queries: when the code and the goods disagree
The tariff classification decides the duty rate and can decide whether a permit or product certificate is needed. A code chosen by the supplier, copied from an older shipment or picked because it carries a lower rate is a common trigger for a query. So is a vague description such as "spare parts" or "accessories" that could fall under several headings.
Settle the classification deliberately before shipment, based on what the goods are, what they are made of and what they do. Describe the goods on every document in enough detail for the classification to be obvious to someone reading it for the first time. If the product is genuinely borderline, decide the position in advance and keep the technical literature ready.
Where assessments typically stop
| Cause of the stall | How importers prevent it |
|---|---|
| Declared value questioned | Invoice reflects the real transaction, with contract and payment evidence ready |
| Classification queried | Code agreed before shipment from a full description of the goods |
| Documents disagree | Quantities, weights, values and consignee details checked side by side before sailing |
| Bank-side documentation late or mismatched | Import documentation opened before shipment and matched to the final invoice |
| Certificate missing for regulated goods | Product certificates and permits obtained while the cargo is at origin |
| Query left unanswered | A named local contact with the documents and authority to respond the same day |
Why a small query becomes a long delay
Most stalls begin with a modest question. They turn into long delays because of what happens next: the query reaches an overseas head office in a different time zone, the supplier has to be asked for a corrected invoice, an amendment to the bank-side documentation has to be processed, and a decision on paying additional duty waits for internal approval. Meanwhile the container sits in the terminal and the free time on storage and shipping-line charges runs down.
An assessment that has been reopened can also make a physical examination more likely, which adds terminal scheduling to the delay. The cost of a stalled assessment is rarely the duty difference itself; it is the storage, demurrage and lost selling time that build up while the answer is found.
Planning your next import assessment with Vandyvah
Vandyvah works with importers, manufacturers and overseas forwarders on customs clearing through Nigerian ports. We review the invoice, packing list, bill of lading and bank-side documentation together before the cargo sails, flag valuation and classification questions while the supplier can still correct them, and on arrival coordinate the assessment, respond to queries promptly with the right supporting documents, and keep the importer informed every day until release.
If you have cargo on order or about to ship, contact our operations team before it leaves origin. A document review at that stage is the most practical way to make sure the assessment moves on arrival instead of waiting on a query.
Customs assessment: before the cargo sails
- commercial invoice reflects the actual transaction price and terms
- purchase contract, proof of payment and freight documents filed together
- tariff classification agreed from a full description of the goods
- goods described in the same detail on every document
- quantities, weights, values and consignee details matched across the set
- bank-side import documentation matched to the final invoice
- certificates or permits in hand for any regulated goods
- a named Nigerian contact with copies of every document and authority to respond
Where delay usually develops
- declared value questioned with no supporting evidence ready
- classification copied from an older shipment or chosen by the supplier
- vague cargo descriptions that fit several tariff headings
- corrections needed to the invoice or bank-side documentation after arrival
- queries waiting on approvals from an overseas head office
What the principal should prepare
- an invoice and contract that reflect the real transaction
- technical descriptions and literature for the goods
- bank-side import documentation matched to the final invoice
- funding and a named contact able to approve additional duty quickly
What Vandyvah can coordinate
- pre-shipment review of value, classification and document consistency
- supplier corrections while the cargo is still at origin
- assessment follow-up and prompt responses to customs queries
- examination scheduling with the terminal when one is required
- daily status updates to the importer through to release
