Chlabs — CN23 Customs + CP72 Labels

Review Amazon CN23 customs and print France/international CP72 labels on Amazon and Octopia.

Chlabs — CN23 Customs + CP72 Labels brings two postal workflows into one extension, with grouped actions and a shared review layout on Amazon Seller Central. CN23 customs declarations (Amazon) For eligible merchant-fulfilled orders outside the standard EU customs territory, review recipient and item information. Edit the description, HS code, origin, quantity, weight, and declared EUR value before certifying and confirming. The extension submits the reviewed declaration directly to La Poste. La Poste returns a withdrawal code and can email it to the configured seller address. Eligible unshipped and confirmed or shipped orders are supported, including supported special customs territories. Saved declarations and PDFs remain available locally for 10 days. Ordinary EU customs destinations do not show the CN23 action. CP72 and France address labels (Amazon and Octopia/Cdiscount) Review the visible delivery address and print it on a France 210 × 102 mm form or international CP72 240 × 152 mm form using a paired Epson LQ-350 workstation. Sender details are editable, support two email addresses, and print only when enabled for that preview. France and international calibration are saved separately. Octopia accepted, confirmed, shipped, and delivered seller-fulfilled orders can be reprinted after review; unsupported or ambiguous orders and addresses are rejected. Printing uses the configured authenticated Chlabs print relay and a separately installed Windows Epson printer bridge. The extension package includes no printer pairing secret. Pair it in Settings, or privately import a profile exported from a previous Matrix Print extension. Opening the popup, choosing a feature, importing settings, or switching reviews does not print or submit anything. The workflows use separate processing paths: address printing does not require the La Poste CN23 website, and CN23 does not require the Epson bridge. Printing does not purchase postage or create a customs declaration. The extension contains no advertising, analytics, or remotely loaded executable code. Marketplace passwords remain in the browser's signed-in sessions. Review customs classifications and declarations before submitting; this tool does not provide legal or customs advice.
