My project requires items from an Approved Manufacturers List (AML). Can STS accommodate this?

Yes, we have extensive experience sourcing materials that comply with AML requirements. Just email us your material list or cart number along with your AML, and we'll take it from there.

My project has country of origin restrictions. Can STS help?

Yes! Our product listings include origin options such as Domestic, Non-China/Non-India, and Unrestricted Import. These are commonly available on items like stud bolts and structural bolts, but we can accommodate origin requirements across a wide range of materials. If you don't see what you need, just reach out to us via email.
