How the exchange works
Physical mineral flow and digital compliance move together.
01
Register
Role-based onboarding with category-specific compliance documents, approved by NM-EX.
02
Log purchases
Tin sheds and aggregators record every parcel — 20 kg or 2 tonnes — in a private ledger.
03
Reach the MML
The minimum marketable lot unlocks Submit for inspection automatically.
04
Verify
48-hour sample window, official assay and weight at an approved warehouse. The assay is locked to the lot.
05
National Pool
Qualified domestic smelters see every verified lot first, priced off the live LME reference.
06
Accept or clear
Acceptance issues a DMO-A. No acceptance in five days issues an export clearance — DMO-EC or DMO-ER.
07
Smelt & re-offer
Refined metal returns to the pool for Nigerian industry before it can leave the country.
08
Verify at the border
NESS and Customs confirm any certificate by QR or number against the live record.
Domestic-offer first
Every lot is offered to Nigerian smelters before it can leave the country.
A verified lot enters the National Pool for 5 days at the government reference price — LME × CBN rate × contained tin — with the domestic purchase at a coefficient of 0.725. Acceptance issues a DMO-A and transfers the 7.5% royalty liability to the smelter. No acceptance issues an export clearance with the royalty assessed on the full reference value.
DMO-A
Acceptance

DMO-EC
Export clearance · concentrate
No smelter accepted. Royalty due on the full reference value before clearance.
DMO-ER
