# Extended BOM
The TrustedParts.com web site offers a BOM Import/Export Part Search tool. By default, this tool has a 100-part limit on searches. If you need to perform larger searches, you can request access to the Extended BOM feature. This feature allows approved users to submit searches of up to 1,000 parts at a time when using the BOM Import/Export Part Search tool.
