I have pointed out quite a few pages ago that commercial invoices can ONLY be in FIAT.
Customs want a proof of the value of shipment on which to apply their duty taxes.
And it is even harder than this: usually (obligatory in my business) you need to have an international auditor inspecting the cargo to verify quality and value which needs to be verified to avoid any false declarations of value (over-priced to allow individuals to take out USD commissions or under-priced to avoid paying customs).
So any Urea Seller can only declare the proper USD value of the shipment.
How the Seller collects payment is another matter. It can very well settle the payment in UROs and can even arrange for credit for as long as it wants.
With one minor detail: it will have to explain to the tax authorities where the difference between Commercial Invoice in USD and payment in URO has gone. Covering the loss between USD/URO is one thing, covering the tax man for millions of tax evasion is another (bad) thing.
Bottom line is that Invoices / Freight documents can NOT verify that any shipment is paid in URO (or any other coin for that matter) and that the seller has some VERY creative accounting to do.
Keeping an open mind and not being a know-it-all I leave a small probability that businessmen smarter than me have figured out brilliant, game-changer methods.
its not rocket science, claim local currency on invoice to hand to duty officer and tax man...
Pay duty fees / importation fees in local currency....
Sell urea to your buyers for local currency... Profit all in local currency....
Only thing URO here is the payment from importer to factory,
all taxes would be paid in relevant local currency's and the profits are still there to do so.
But that would mean the factory auto dumps 12500 tons of uro price on exchange.......
But on the good side the buyers have to buy that 12500 URO form exchange....
