A non-verified (Custom) material is a Library entry that does not come from a published EPD. Use it when you need a material to map elements against but no EPD exists — for example, an early-phase estimate, an internal product specification, or a placeholder while you wait on a manufacturer’s documentation. Custom materials show up in the Library with the Custom type and are filterable just like any other material.
Custom materials are not third-party verified. Make sure that everyone in your organization understands that the indicator values are author-supplied estimates, not declarations.

​
Open the Custom form

From the Create Material page, click the Custom tab at the top.
Custom tab selected with General Details (Name, Life Time, Description), EPD Units (Declared value, Unit, Mass value, Unit), and the beginning of EPD Sources.
The Custom form is a leaner version of the Published form: there is no EPD specification, no document upload, no declaration number, and no owner/data source — because there is no underlying EPD to declare.

​
Step 1: General details

FieldNotes
Name (required)The name shown in the Library.
Life Time (required)Expected service life in years.
DescriptionA short description shown on the material detail panel.

​
Step 2: EPD units

FieldNotes
Declared value (required)The numerical declared quantity.
Unit (required)Unit for the declared value (for example, m², m³, kg).
Mass value (required)The mass per declared unit.
Unit (required)Mass unit (typically kg).

​
Step 3: EPD sources

FieldNotes
Category (required)The material category that drives filtering and grouping.

​
Step 4: Life cycle indicators

Enter the indicator values you want the material to contribute for each module (A1–A3, A4, A5, B1–B7, C1–C4, D).
EPD Sources category dropdown above the Environmental impacts per declared unit table for a Custom material.
The table mirrors the one used for verified EPDs. Fill in whatever modules and indicators apply to your case and leave the rest as -.
Cloning an existing material (Library list → row’s ⋮ menu → Clone) is the quickest way to start a Custom material when you only need to tweak a few numbers.

​
Step 5: Save

Click Create Material at the bottom of the form. Your custom material appears in the Library with the Custom type tag and is available to every project in the current organization.
