Packages and weights
Package sizes, packaging weight, and what happens to products without a weight.
Last updated 17 October 2026
India Post charges and checks parcels by weight and size, so every shipment needs both.
Packages#
Under Settings → Packages, add the boxes you ship in: a name, the outer length, breadth and height of the packed parcel in cm (decimals are fine), and the empty packaging weight in grams (box plus filler). One package is the default for new shipments; you can choose another on any shipment before it’s booked. If your product weights in Shopify already include the box, tick My product weights already include the packaging (use 0 g).
Weight#
- A shipment’s weight is its items’ weights from Shopify × their quantities, plus the empty packaging weight, once per parcel. Only the items in that shipment count.
- Products without a weight in Shopify, on the same page: Hold the shipment for review (recommended) keeps it under Needs attention until you enter its packed weight. Use the fallback product weight uses the weight you set (per item, 1 to 35,000 g): such shipments are marked Estimated, are never booked automatically, and Book N ready asks you to confirm before booking them.
- You can enter the actual packed weight on a shipment before it’s booked. It replaces the estimate; packaging isn’t added again.
- Editing a package changes shipments not yet booked when they’re next checked. Booked parcels keep the size and weight they were booked with.
Limits#
They depend on the service (from India Post’s rules, as the app checks them):
| Service | Weight | Size (length × breadth × height) |
|---|---|---|
| Documents (Speed Post, 24h and 48h) | Up to 500 g | Up to 42 × 29 × 2 cm |
| Parcels (Speed Post, Business Parcel) | Up to 35,000 g | At least 14 × 9 cm; each side up to 150 cm, all three together under 300 cm |
| 24h Speed Post Parcel | Up to 5,000 g | At least 14 × 9 cm; each side up to 150 cm, all three together under 300 cm |
For parcels, India Post also works out a volumetric weight (length × breadth × height ÷ 5, in grams) and charges the higher of the two. Labels show both.
