309 U.S. Customs Manifest (003050)

This is the standard X12 003050 spec, with 7 loops and 17 segment positions, as OpenEDI JSON, an ediFabric C# template and an ediFabric Native model. To change it for a trading partner, customize it in the EDI Spec Builder.

Use the 309 spec in your code

ediFabric .NET

Add the C# template and its common files to your project, or reference the template NuGet package, and read 309 files into TS309 objects. See ediFabric .NET.

ediFabric Native

Map version 003050 to the Native model with set_map, then parse 309 files to JSON from Python, Java, C or C#. See Convert between EDI and JSON.

OpenEDI

Select Customize in Spec Builder to copy the spec under your own name, change it for your partner, and parse files against it in EdiNation, ediFabric Native or ediFabric Cloud. Read about OpenEDI.

Generate 309 classes in Python, Java, Node.js, Go, Rust or C

ediFabric Native returns each 309 as JSON, with the property names of the OpenEDI schema. To work with that JSON as typed objects, generate classes from the OpenEDI file in your language and deserialize the JSON into TS309. Serialize the objects back to JSON to build EDI with ediFabric Native. The classes keep the loops, segments, lengths and code lists, but not the EDI data formats, so validate files with ediFabric Native. Read more in Generate a class from OpenEDI.
