# Publication Service

> Ship flat, lightweight media items like magazines, books, and CDs at a dedicated Publication rate

Publication Service is a shipping option built for flat, lightweight media — magazines, books, CDs, vinyl records, calendars, booklets, and similar printed or thin-format items. It's priced separately from Standard, Express, and Rush, so you're not paying parcel rates for something that isn't a parcel.

## What qualifies

A shipment qualifies for Publication Service when it fits within these limits:

| Limit  | Maximum |
| ------ | ------- |
| Length | 14 in   |
| Width  | 14 in   |
| Height | 1.5 in  |
| Weight | 1.5 lbs |

Anything above or outside these dimensions falls under our standard parcel pricing rates instead of the Publication rate.

<Note>
  Dimensions are checked first. If your package exceeds any side of the 14 × 14 × 1.5 in limit, it won't qualify for Publication Service even if the weight is under 1.5 lbs.
</Note>

## Availability

Publication Service is available for **Canada-domestic shipments only** — it isn't available for cross-border or U.S.-domestic shipments. Same-day delivery isn't offered for Publication shipments.

Publication Service is currently only available when you create a shipment manually in the UniUni Platform. It isn't supported yet through the REST API, CSV import, Shopify, or WooCommerce.

## Selecting Publication Service

When you create a shipment manually, choose **Publication** as the service type at the postage step. The rate shown reflects the dedicated Publication pricing — not Standard or Express rates — so review it before confirming.

## Protection

Publication shipments include tracking. If you want coverage against loss or damage, you can add [Parcel Protection](/en/services/add-on/parcel-protection) the same way you would on any other shipment.

## Finding Publication shipments

Publication shipments show their service type in your shipments list, and you can filter the list down to just Publication shipments.
