Priya's list is comprehensive. Two additions from my experience handling similar Germany-India shipments:
Advance Filing: India requires advance filing of the Import General Manifest (IGM) by the shipping line 24 hours before arrival. As the importer/CHA, ensure your documents reach your forwarder/CHA at least 7–10 days before the vessel arrives so the BoE can be filed in advance. Advance filing gets you an "Out of Charge" (OOC) quickly after arrival and minimises demurrage.
HS Code accuracy is critical in India: Indian customs officers are strict about HS code classification, and the duty rates vary significantly even within sub-headings. For industrial equipment, I recommend getting a pre-import HS code opinion from your CHA or, for high-value shipments, filing for an Advance Ruling with the customs authority. Wrong classification can lead to demand notices for duty differences + penalties even after clearance.
