What's in a consignment record, field by field.

Every lot we deliver ends in one consignment record. It isn't written at the end; it's assembled from the stickers, weights and checkpoints that each earlier step already produced.

This piece goes through it field by field, using the illustrative record shown on How it works. The values below are sample data, not records of material collected.

Lot reference: LFP-2026-08-13

The lot code carries the chemistry and the date the lot was opened at the yard. A second or third lot of the same chemistry on the same day gets -B or -C. Because the chemistry is in the reference, nobody has to open a pallet to know what kind of feedstock it is.

Chemistry and units

Chemistry is stated once for the whole lot, because a lot holds one chemistry only. Units is the number of packs sealed into it: in the sample, 312 LFP EV traction packs.

Pickups and stickers

Pickups lists how many collections the lot was built from, with their references (PK-20260811-02 is the date plus a sequence). Stickers lists the pack identifiers inside the lot, in the form OE-000412. The record shows them as a range; the lot manifest lists every sticker individually, each one linked to the pickup it came from.

That link is the point. Any single pack in the lot can be traced back to the seller, the date and the weight recorded at the door.

Vehicle

The registration of the vehicle that carried the lot. It ties the record to the truck that crossed your weighbridge and to the e-way bill that travelled with it.

Weight in, weight at gate, variance

Weight in is the sum of the individual pack weights recorded at pickup, each backed by a photo of the scale reading. Weight at gate is your weighbridge figure. The variance is the difference between them, in kilograms and as a percentage, and it's written down rather than rounded away. In the sample, 6,214.0 kg in against 6,208.5 kg at the gate: a variance of 5.5 kg, or 0.09%.

A small variance with an explanation is normal; scales differ and handling has an effect. A large or unexplained one is a question, and individual pack weights are what make it answerable. More in A battery changes hands.

Source and destination

Source names the districts the packs were collected from. Destination names the recycler, which is always CPCB-registered. Under Rule 7 of the Battery Waste Management Rules, 2022, entities involved in collection must “hand over Waste Battery to registered refurbisher or recycler.”

Custody

The custody line is the lot's timeline: collected (stickered and weighed), yard in (scanned at the yard), sealed (against the safety checklist), dispatched (with the e-way bill number) and gate in (at the recycler's weighbridge). Each event is a timestamp written when it happened, not a reconstruction.

1. 01

   Collected

   Stickered and weighed at the seller's door.

2. 02

   Yard in

   Every sticker scanned in at the yard.

3. 03

   Sealed

   Against the safety checklist.

4. 04

   Dispatched

   With the e-way bill number.

5. 05

   Gate in

   At the recycler's weighbridge.

Who uses the record?

Recyclers use it to check a lot against their specification and to support the quarterly returns they file on the waste batteries they receive and process. Auditors use it because every figure on it traces back to a transaction.

What the record doesn't do is create certificates. Under Rule 10, EPR certificates relate to quantities recycled or refurbished by registered recyclers and refurbishers. We explain how that works in Battery EPR certificates.

What to ask of any supplier's record

Does it name a single chemistry? Can every unit be traced to a pickup? Was each weight recorded individually, with evidence? Is the gate weight reconciled and the variance written down? Is the destination a registered recycler?

If the answer to all five is yes, the record is doing its job. To agree what your own lots should look like, read what a feedstock specification should cover or talk to us about supply.
