The short answer
The quote should state the delivery point and which party handles freight, insurance, customs and taxes. Product classification and local requirements need confirmation for the destination.
In more detail
Prototype shipments and production orders may need different transport arrangements. Battery documentation, packaging and delivery timing should be reviewed with the carrier or logistics provider.
Customs classification and declared values need an accurate description of the actual goods and transaction. Final import treatment should be checked with the appointed broker; a website estimate is not a landed-cost commitment.
