100%. I did business for many years with China. Try shipping something / anything in a parcel to China. Chinese Customs is guaranteed to open the box, open the package inside (even if it means destroying it), and require every possible shipping document, testing document, and local customs permission possible.
They make it extremely difficult to ship any parcel there, even zero-value industrial samples. Forget about running a sales business in such a way. Its absolutely impossible.
But they do not treat the outgoing shipments that way.
Jut opposite!
“Try shipping something / anything in a parcel to China.”
China is EASY compared to Canada.
I used to somewhat regularly ship specialized test equipment into Canada. Nightmare.
