I am working in a trade company .And Im a logistic specialist. We main purchase goods and export to abroad.So sometimes I need contact with China Customs.Today one shpt was detained because of something wrong with one conduct's model.My supplier forger to print the model on the package .I think that is not a big problem.We can apply for changing customs declaration. But it has 15 working days.So long ,and will delay in delivery of cargo. I export the shpt by express.why does the customs need so long day to deal with it? So Im confused about customs responsibilities.Just because they are goverment workers ,so they don't worried about our company profit?
