30 yuan/piece + handling fee 30 yuan;
Therefore, for example, for a 10KG cargo, the magnetic inspection fee is 30+30=60 yuan;
For two pieces of goods in one ticket, one piece is 10KG and one piece is 40KG, the magnetic inspection fee is 30*2+30=100 yuan;
The standard magnetic inspection fee is 30 yuan per piece of cargo plus a handling fee of 30 yuan. For example, the magnetic inspection fee for a 10KG cargo is 60 yuan. If two pieces of cargo in one ticket are 10KG and 40KG respectively, the magnetic inspection fee is 100 yuan.
