The shipping world is full of jargon! We decided to do our bit with this glossary. Let us know if you'd like to suggest for any more additions!

Air Waybill label

The Air Waybill is the identification number of your booking with the airline. It states the weight, origin and destination, and number of pieces in your shipment.

Zenda provides you with an Air Waybill label when you close out a shipment. You must attach one Air Waybill label to each piece. The number of pieces displayed on the air waybill must match the number of pieces you are sending.

Close Out

Close out is the process of booking a shipment.

It is the last stage of the shipping process, after you have packed your orders into parcels, and placed your parcels into one or more pieces.

Consolidation Manifest

The Consolidation Manifest is a document that describes the details of your shipment. It is required in case your shipment needs to be inspected by customs authorities. The document includes the shipment's origin, destination, airline carrier and the Air Waybill number.

Zenda generates a Consolidation Manifest when closing out a shipment. You must print and attach it to the outside of one of your pieces, inside a document pouch.

Commodity code

Importing into Europe requires identifying each of your items and mapping it to a 10-digit commodity code. The first 6 digits of the commodity code are also known as a Harmonised System or HS code. The additional four digits add more details about the item, which are required to clear customs.

During onboarding, Zenda takes care of mapping your item catalogue to 10-digit commodity codes. This process also powers the tax and duty calculator in Zenda Checkout.


Consolidation is the process of combining one or more parcels into a single shipment, so that it can be shipped more efficiently.

Dangerous Goods

Dangerous Goods are defined by the latest edition of the IATA Dangerous Goods Regulation.

Dangerous Goods cannot be shipped with Zenda, and it is your responsibility as the Shipper to ensure Dangerous Goods are not shipped undeclared.

If you have any questions on this, please contact your accounts manager.


Deconsolidation is the process of breaking down a shipment into individual pieces and then into individual parcels, so that they can be delivered to their respective last mile addresses (your customer's home).

Delivered Duty Paid

Delivered Duty Paid, or DDP, is a shipping arrangement where the shipper is responsible for paying any owed taxes and duties to the importing country's customs authorities.

Most goods imported from outside the EU are subject to taxes and import duties. With Zenda, your customer can avoid delays and hassle by paying all fees in advance.

Zenda enables DDP by providing a real-time calculation of taxes and duties in your store checkout, so you can collect all required taxes and duties from your consumer upfront. Go to Zenda Checkout page for more details.

Delivered Duty Unpaid

envelope with surprise extra import tax and duty

Delivered Duty Unpaid, or DDU, is a shipping arrangement between the shipper and their customer where the customer is responsible for paying any owed taxes and duties, once the goods arrive to their country. These fees were not collected at the checkout, and so have to be paid upon delivery.

DDU has been the primary way to ship a package to a cross-border customer. Delivered Duty Paid shipping solutions, like Zenda, avoid surprise extra fees and delays for your customer by allowing them to pay for all taxes and duties in advance.

A Known Shipper is an individual or entity that wishes to tender their goods for air transportation on a passenger air carrier.

To ship with Zenda, you must be registered as a Known Shipper with British Airways and have gone through an approval process mandated by the US Transportation Security Administration (TSA).

This process is very straightforward – you'll just have to fill in a Known Shipper form as part of your onboarding process with us.

Last Mile Label

A Last Mile Label is a shipping label that contains your customer’s delivery address. One Last Mile Label must be attached to each parcel.

ZEN tracking number

The ZEN tracking number is the unique identifier for each parcel in Zenda. You'll use this number to track each parcel with us.

A ZEN tracking number always has 20 characters in total, starting with 'ZEN'. An example is ZEN00001A0611X000059.

This is the breakdown:

  • Characters 1-3: Always 'ZEN'
  • Characters 4-8: Merchant identifier
  • Character 9: Warehouse letter (if you only have one warehouse, this will always be 'A')
  • Character 10-13: Date of the creation of the parcel, in the format DDMM
  • Character 14: Always X (a separator)
  • Character 15-19: Parcel number
  • Character 20: A check digit

When you create parcels in Zenda Ship, ZEN tracking numbers will be automatically attached to the order in your store. Find out more here.
