01Battery identity register
List cell or battery maker, model, chemistry, nominal voltage, rated capacity, watt-hour rating, mass and physical description for the earbuds and case. Record which finished-product models use each battery and how substitutions are controlled.
02UN 38.3 test summary
Obtain the test summary required by the UN Manual of Tests and Criteria. Check maker and contact, laboratory, report identifier, date, battery description and model, watt-hour rating, tests and results, manual edition and signatory. Resolve any model mismatch before booking.
03Finished-product configuration
State how earbuds and charging case are assembled, switched off or protected, placed in retail packaging and packed in cartons. The transport classification and instructions depend on whether batteries are shipped alone, packed with equipment or contained in equipment.
04Quantity and state-of-charge inputs
Provide units per retail box and carton, battery count, watt-hours and relevant state-of-charge information. Do not assume a small consumer battery removes every requirement. Current air rules and carrier variations must be checked for the actual consignment.
05Damage and short-circuit protection
Confirm terminals and charging contacts cannot short, products cannot switch on unintentionally and cells are protected from movement, crushing and damage. Remove damaged, defective or recalled batteries from ordinary shipment planning and escalate them to qualified handling.
06Marks, labels and paperwork
Ask the trained shipping party which package marks, labels, shipper information and declarations apply. Verify print size, durability and placement on the final carton. Keep the transport record with the commercial invoice, packing list and carrier booking details.
07Carrier and route confirmation
Provide origin, destination, mode, service and package details to the carrier or dangerous-goods specialist. Carriers may impose stricter limits than baseline regulations. Reconfirm after a route, airline, forwarder, battery or packing change.
08Shipment handoff record
Keep the battery register, test summaries, packing version, marks, declarations, trained preparer and carrier acceptance together. Record the date and revision used so a later reorder does not silently rely on an obsolete file.
