# How to import products from a GTC package

Bulk-import a vendor's product catalog into the Tooling Metrics Library from a GTC package file.

**Prerequisites:** You have a GTC package `.zip` file from your cutting tool vendor (e.g., Sandvik Coromant, Iscar, Tungaloy). GTC packages can be downloaded from the vendor's website or requested from their sales representative: [Find a manufacturer's GTC package](https://support.toolingmetrics.com/en/library/guides/find-gtc-packages/) lists where each manufacturer publishes them.

**Required permission:** Library → Products — User or above.

## Steps

1. In the sidebar, click **Library → Products**.
1. Click the **Import** button in the navigation bar.
1. In the import dialog, click **Choose File** and select your GTC package .zip file. Your browser reads the package locally and a table shows its metadata (vendor name, acronym, hierarchy version, creation date), then uploads the file in the background — a progress bar tracks it.
1. Click **Import** once it's enabled. It stays disabled until the background upload finishes, even though the metadata table appears right away.
1. The dialog closes and a flash confirms: "GTC package import started." The import itself runs as a background job — it is not done yet.
1. When the bell icon at the bottom of the sidebar shows a red dot, click it to open **Notifications**. The completed message includes a downloadable import report.

After the import, click the **Products** icon in the sidebar to refresh the list — the page you were on does not update on its own.

## Notes

- If the package contains thousands of products, import may take several minutes.
- Products from the same vendor imported a second time update existing records rather than creating duplicates.
- To add products from a manufacturer not available via GTC package, see [How to Create a Product Manually](https://support.toolingmetrics.com/en/library/guides/create-product-manually/).
- If the import fails or products are missing afterwards, see [Troubleshoot a GTC import](https://support.toolingmetrics.com/en/library/guides/troubleshoot-gtc-import/).
