FAQ
Resource Hub FAQ
What is the shortest path to a quote?
Choose the closest product series, upload the drawing package and add optional material, finish, BOM or terminal schedule details if they are already defined.
Can I upload incomplete files first?
Yes. The new intake flow starts with email plus files. Complete packages can move into AI budgetary quoting, while missing details move to manual review.
Which resource pages matter most before RFQ?
Most buyers should review the RFQ checklist, CAD file guide, rating guide and inspection photo page before sending a prototype request.
Compliance and import wording
Built for NEMA-style and IP-rated applications. Final rating depends on design, materials and testing requirements.
Import duties and tariff treatment depend on HTS classification, country of origin, material and product configuration. Final tariff confirmation should be reviewed by the importer’s customs broker.
