Following widespread spurious claims by persons who posed as customs agents, set up illegal Customs auctions, and effectively fleeced the unsuspecting public, the NCS (Nigeria Customs Service) decided to set up the Customs e-auction operation at app.trade.gov.ng/eauction

The website regulates all auction activities of the Nigerian customs service. The following process and notes enable you to participate and claim a car via the Nigeria Customs’s auction system:

1 - Each auction applicant needs to register on the website prior to bidding. The applicant needs to have a Tax Identification Number (TIN) from the Federal Inland Revenue Service (FIRS). Each applicant must in addition attach an active e-mail address with their registration.
2 - The Applicant then pays a fee of One Thousand Naira (₦1,000) as non-refundable process fees.
3 - The applicant can then place a maximum of two bids for each auctioned item. Highest bidder wins.
4 - Applicants must note that items auctioned are done so on an “as is” basis. That being the case, the NCS does not accommodate requests for replacements of faulty or damaged items. Refunds are also not made by the Nigerian Customs.
5 - You are expected to pay the full amount of your successful bid no later than 5 working days after the conclusion of the bid process. Failing to claim the auctioned car by the full payment before the end of the fifth working day automatically results in a loss of the bid. The auctioned item then goes to the number 2 highest bid.
6 - Having paid the full bid amount, you will be given 14 days maximum to take possession of the car. You need to know that additional charges may apply at this point. For instance, number 8 of the auction site’s terms and conditions state that you may need to pay 25% of your winning bid sum as demurrage and another 25% for the shipping line. You will automatically forfeit your car if you fail to remove it from the storage premises at the end of 14 days after your bid session.
7 - Cars not removed by the expiration of the deadline once again become NCS property and may undergo another bid session. Funds thus lost are not refundable.
8 - As stated earlier, the NCS specifically warns that “ for overtime cargo, the successful bidder shall in addition pay 25% charges for Shipping Line and Terminal operators respectively”.
9 - Each applicant cannot bid on more than 2 auctioned items for any single bid session.
10 - In order to claim successful, fully paid for auctioned cars, you will need to present the following:
a) A copy of paid assessment and bank receipt (this is optional if you made an e-payment).

b) If the bidder cannot appear himself, a notarized letter is necessary before a proxy can be given the car. You need to make sure your uploaded photo matches your photo ID.

c) You will need to provide valid ID, which can be any of Driver’s license, International passport, National ID card, or PVC (Permanent Voter’s Card).

11 - Each auction window lasts for two days or Forty-eight hours. All bids must be placed during this period.
12 - Third party claims shall not be entertained.
13 - Officials and employees of the Nigeria Customs Service may not participate in auctions organized by NCS.
14 - You may not bid for a car or other goods impounded or seized from you by the Nigerian Customs.
15 - You may bid on an overtime cargo if you are the owner as long as it has not been cleared out of the premises. In that case, the owner will have priority over any other successful bid.
