Hi, my company recently bought a shipment of oil used in fire resistance product from US. We ordered once before in 2011, and the TC is 3813.00.0000 (0 % Duty fee but 6%GST)
But this time (Same company we ordered from US), there's no TC listed in invoice, my only worry is the custom will charge us using different TC, and the whole shipment cost around 1536$ Dollar including Courier using USP, so 20%-30% duty fee is ridiculous.

If custom happened to charge us using wrong TC, can i argue with it using previous invoice?

Another is, do we declare our own to custom or the courier service (UPS) will handling for us, and we only provide necessary document?

Sorry for the newbie question...the person in charge resigned recently
