Procurement notes

Documentation and RFQ checkpoints

Lithium shipping documentation

Global buyers usually confirm shipment files before sampling or volume delivery.

  • • UN38.3 and MSDS / SDS planning
  • • Battery labels and shipping information
  • • Packaging and transport-mode checks

Europe battery documentation checklist

European OEM programs usually need documentation planning earlier with the importer and engineering team.

  • • CE and IEC review path
  • • RoHS / REACH information where relevant
  • • Importer files and product labeling

OEM RFQ input checklist

Custom cell or PACK programs should clarify engineering inputs before quotation.

  • • Voltage, capacity, continuous and peak current
  • • Size, enclosure, connector, harness, and BMS communication
  • • Target market, certification expectations, and estimated annual volume
