About PartsMaster

PartsMaster is a database of over 15 million active and cancelled parts used by the United States Military and civilian agencies.

A PartsMaster NSN report is a comprehensive gathering of all related information about a part in a single page.

ALI Corp. originally created PartsMaster in 1988 for DOD contractors and OEMs to find research information about a part before bidding. Since then we have added a number of databases to this report and have made it available to both military and commercial clients. Who uses PartsMaster?

Using the DOD's NSN (National Stock Number), NIIN (NSN without the first four digits), or a Part Number, anyone on the web can find basic information about any part free of charge in an Public Report. For a small fee (as little as 50 cents) PartsMaster will gather information from up to 27 different databases and present it to you in an easy-to-read Full Report.

If you don't find what you are looking for under that specific number, you may use ALI Corp.'s latest innovation: SIMILAR PARTS. It will provide a list of any other parts made by the same company (or listed under the same CAGE Code) that is in the DOD's 15 million NSNs list. Also, it will look for other parts that are similar in identification. These are listed in relevance order so that you can use the information to find possible suppliers.

You may purchase as few as 1 reports or as many as 600. Of course, the more reports you purchase, the lower the price.

Please note not all NSNs have data in all 27 databases. You may always run a free search to see what is available before purchasing a report.

Other Ways to Find a Part

If you still can't find a supplier or similar part, you can try Parametric Search or SOSID.

Parametric Search will show you a list of the Technical Characteristics of your part and allow you to define the most important ones. Then, you'll get a list of up to 120 parts in order of importance to you. You may then get an NSN report on any or all of them. If your part has no Technical Characteristics defined, you can make your own list from the parameters of the type of item you are searching for.

Source of Supply Identified or SOSID will reduce your search for a supplier. You may search by exact NSN/NIIN or by starting part number or by the CAGE plus INC (item category). It's easy and takes a lot less time than examining tons of data just for a name and phone number or email.
