Cubeship / US CustomsCUSTOMS FILING FOR PARCELS
Parcels in.
Entries filed.
Cubeship US Customs turns a sheet of parcels into customs entries for U.S. Customs and Border Protection (CBP): each one built, validated and transmitted, with the answer of CBP next to the row it came from.

Keys are personal. None is published on this page.
Upload a sheet of parcels. Get every entry back.
One row per article; rows that share a reference are one parcel. Each parcel comes back as an informal entry — type 11, and type 13 for international mail — built, validated against the rules CBP publishes and transmitted, with the answer of CBP written next to the row it came from.
The sheet asks for the tariff number, the value, the origin and the quantity. The unit, the duty and the additional tariff lines are worked out by the engine.
Or let your agent run it.
The same engine answers over MCP: an agent checks a sheet, sends it, and follows each answer, with the same key and the same permissions as the page.
