- Tea type and grade
- CTC BOP, BP and PD, orthodox FTGFOP and dust grades differ in leaf size, liquor and price. The grade on each line is how tea is bought and sold, and it is what a tea stall owner will check by brewing a sample.
- Garden mark or blend number
- Wholesalers sell either garden-specific teas or their own blends. The garden mark or blend number lets buyers reorder the same taste and lets you trace complaints.
- Auction lot and sale number
- Tea bought at Kolkata, Guwahati, Siliguri or Coonoor auctions carries a lot and sale number. Quoting them on the invoice supports origin claims and lets you trace quality back to the purchase.
- Packing and net weight
- Tea moves in 50 kg paper sacks, 25 kg bags or retail packs. Net weight per pack helps reconcile deliveries.
- FSSAI licence
- Food business operators must print their licence number on invoices. Tea is frequently sampled for added colour.
- Tea Board registration
- Tea traders, blenders and exporters register with the Tea Board. Printing the registration number assures buyers that you trade in the regulated supply chain.
- Moisture and storage note
- Tea absorbs moisture and odours. A storage note on the invoice sets expectations for buyers who store tea in kitchens or godowns.
