Used by maintenance and procurement teams to review secondary-market listings, create purchase case records, and protect against risky industrial eBay buys — before money is spent.

Compliance evidence — what CT Permit-to-Buy documents
ISO 9001:2015 Clause 8.4
Control of externally provided products. CT generates the pre-purchase evaluation record your auditor requires before secondary-market parts enter your system.
NIS2 Article 21 — Supply Chain
OT components from unauthorized sources are an undocumented supply chain risk. CT Permit-to-Buy creates the evidence record NIS2 supply-chain governance requires.
PO · Card · Reimbursement
No CT Permit ID — no approval. CT Case ID attaches to the purchase order or reimbursement form as the documented pre-purchase control record.
CT reviews listing-level risk only. CT does not physically inspect, authenticate, certify, insure or guarantee the part.
CT works for a single engineer checking one listing — and for procurement teams monitoring their entire critical parts portfolio every week.

From public industrial forums
Engineers describe the pain — in their own words.
These are public comments from PLCtalk.net, an industrial automation forum. They are not customer testimonials or endorsements of CT Ultramax.
"eBay is our last resort. It's just so easy to get scammed. Sometimes when you're down, you grab the part from more than one seller at the same time and hope one of them works."

"Typically this goes into a site manager's credit card. Procurement will never even be aware of it. I've seen UPS's and even mass flowmeters being bought on credit cards."

"Most of those listings are Chinese sellers selling either counterfeit or remanufactured parts as new. When I'm trying to find actual surplus I take good care not to buy from those types."
