open market, broker, grey market, excess inventory, secondary market
The open market is not a place. It is the sum of every unit of stock that exists somewhere other than the factory and the authorised distributor's shelf: a harness manufacturer holding terminals left over from a cancelled programme, a distributor in another region sitting on a line that never moved, a Tier 1 unwinding its buffer after a model change, a stockholder who bought a last-time-buy lot years ago and never used it.
That inventory is genuine, and for obsolete and allocated parts it is frequently the only inventory that exists. This is what makes open market sourcing legitimate, and in a real shortage, unavoidable.
It is also where the risk sits, because scarcity attracts bad supply. The characteristic behaviour is speed and pressure: an offer appears within hours of a request, priced to be accepted before it is checked, from a party with no history and no answer to where the stock came from. What arrives can be re-labelled, recycled, the wrong plating, an off-tool copy, or a genuine lot padded with imitations.
Separating the two comes down to how the buying is done. Known suppliers rather than anonymous offers. A documented chain per order rather than an unanswered origin. Date and lot code checks against packaging and paperwork. Visual and dimensional checks against the manufacturer drawing. Refusal treated as a normal outcome rather than a last resort. The difference between a broker who forwards an offer and a distributor who takes responsibility for it is whether anyone in the chain is willing to say no.
Harness Code sources on the open market through verified channels, documents the supplier chain per order, and checks incoming stock under an ISO 9001:2015 quality system certified by AQ Cert. It declines stock it cannot trace.

Franchised vs independent distributor
A franchised or authorised distributor holds a contract with the manufacturer and buys directly from the factory. An independent distributor has no such contract and sources from the open market: excess inventory, other distributors, and stock outside the manufacturer's direct channel.
Counterfeit risk and verified sourcing channels
Counterfeit risk is the risk of receiving fake, re-labelled, recycled or out-of-specification components presented as genuine. It rises sharply for parts that are scarce, obsolete or on allocation, which is exactly when buyers are forced outside their usual channels.
Suspect counterfeit and incoming inspection
A suspect counterfeit part is one whose authenticity, origin or specification cannot be confirmed. Incoming inspection is the check performed on delivery, covering documentation, packaging, labels, date and lot codes, and the parts themselves against the manufacturer drawing.
Obsolete / End-of-Life (EOL) component
An obsolete or End-of-Life component is one the manufacturer has stopped producing. It usually passes through an NRND warning and a last-time-buy window first, after which the only remaining supply is existing channel stock, excess inventory, or a qualified alternative.
