Vietnam is where a great deal of equipment designed elsewhere is now actually assembled, and that single sentence explains most of the urgent traffic on this desk. A line in Bac Ninh, Thai Nguyen or Binh Duong runs to a schedule set in Korea, Japan, Europe or the United States, and when it stops the part that restarts it is small, foreign and needed before the next shift rather than the next week.
The second driver is qualification and pre-production. Tooling inserts, first articles, test boards, reference samples and approved colour standards move between a foreign engineering office and a Vietnamese plant constantly, and each of them is holding up a sign-off that other people are waiting on. These are the consignments where air freight's honest three to five days is three to five days too many.
The third is documentary. Powers of attorney, notarised corporate resolutions, original certificates of origin and legalised contracts still have to arrive as originals, and the legalisation chain runs through offices with their own hours and their own order. A courier holding the folder can walk it from one counter to the next; a tracking number cannot.
North and south are genuinely different economies and should be planned as such. The north around Hanoi is electronics and assembly; the south around Ho Chi Minh City is broader manufacturing, textiles, furniture and trade. A consignment for one is not a consignment for the other with a different address.
