FAQ
Buying and verification notes
Does the storefront publish live stock or live pricing?
No. RoMaks operates an RFQ-first catalog. Product pages can show exact part identity, available documents, and technical context without presenting unconfirmed stock or pricing.
What happens when a datasheet, image, or lifecycle value is missing?
The field remains unavailable until supporting documentation is confirmed. Similar-part data and generic placeholders are not presented as product facts.
How should buyers submit multiple parts?
Use the RFQ basket or BOM-oriented request flow so quantities, manufacturer context, target price, and sourcing notes can move through the commercial workflow together.
