since 36 plus 24 plus 20 only equals 80k tons and there was ca 88829 tons at port prior to last ship there was an extra ca 8829 tons trucked there either as part of order 5 (making it ca 28829 tons) or order 6.

Dont know reason for different orders to same supposed Bao customer except that they have many plants and different furnaces may be optimized for different size iron-and CWRN has had many different sizes of iron in its orders as per customer specifications.
