One registry, seen through the eyes of each party to the trade. Open them in order to follow a single lot of tin from the miner who dug it to the certificate that clears it for export. A tin shed never sees a smelter’s plant; a verifier checks a certificate without ever seeing the commercial ledger.
How the price is set at every step
Coefficients fixed by NM-EX policy70%
of the LME metal value
A registered miner is guaranteed this floor when selling to a tin shed. NM-EX locks it — the shed cannot bid below it.
72.5%
of the LME metal value
The shed buys at 70% and sells into the National Pool at 72.5%. That 2.5% spread is its locked margin.
72.5%
plus 7.5% VAT
Pays the listing price. The 7.5% royalty transfers to the smelter at ₦0 on acceptance.
Why registration matters. An unregistered miner may still sell to a tin shed, but nothing guarantees the 70% floor — that price is only enforceable for a registered miner. Registration is what turns a quoted coefficient into a guaranteed one.

Tin moves down this list. Each view sees only its own side of the trade.
