What does the shipping time estimator include?

It combines seeded lane transit with customs and delivery buffers to produce a more realistic door ETA window.

Why is the ETA different from carrier transit?

Carrier transit is only part of the timeline, while customs clearance, handover timing, and local delivery also affect arrival.

Can I change the customs or warehouse buffer?

Yes. The estimator lets you adjust planning buffers so you can model a more realistic arrival window.
