1. The timeline problem
Legalization takes three to four weeks. A tender deadline does not move.
The two have to be reconciled before anything is submitted.
2. Work backwards, not forwards
Start at the deadline.
Subtract courier time to the destination.
Subtract embassy legalization.
Subtract foreign ministry authentication.
Subtract notarisation.
Subtract translation.
Subtract the time to produce and sign the documents.
What remains is the start date. If it is in the past, the tender is at risk.
3. The variables that blow up the plan
Translation into a rare language
Arabic and Spanish translation capacity is widely available. Portuguese less so, and some Asian languages less again.
Receiving days
An embassy that receives commercial documents on one day a week adds up to six days of waiting.
Resubmission
Any return resets part of the clock.
Courier to the destination
Not part of authentication, but part of the deadline.
4. What to do first
Identify which documents require legalization, before preparing any of them.
That list determines the volume of translation and notarisation, which is where the time goes.
5. The parallel steps
Document preparation and translation can run in parallel with the enquiry to the embassy.
Notarisation and authentication cannot run in parallel; they are sequential.
6. A realistic buffer
Add a week to whatever the calculation produces, unless the exporter has done that exact chain for that exact destination before.
7. A scenario
A fifteen-day tender deadline with a requirement for embassy legalization is not achievable.
Recognising that at the start saves the preparation effort, and allows the exporter to discuss alternatives with the buyer, such as submitting the tender with a commitment to provide legalized documents later.
8. Closing view
Legalization time cannot be compressed. It can only be started earlier or planned around.
