Sell to Russia?

One week after visiting Sulawesi we had guests from Russia for well cement. The company planned to sell this type of cement from Russia to Australia. 2 Russian guys are manager for well cement and Russia government professor. First day was sampling the cement at silo, plant tour.
The second day testing! My heart was beating faster (than usual, government of Russia).
Testing witness was good and also the result.
On wrap up the professor was surprised by the tester ability, he said never happen before the tester was not nervous and work as professional.
He also suggested us to have a laser Particle size distribution that always postponed since 2004
Yes the audit was successful and we can sell the product as the certificate publish
