T4 · Mexico and the United States
You can't be in the shop. We can.
T4 Inspections is an independent third-party inspector working for the buyer. We put a qualified inspector inside your supplier's facility, in Mexico or the United States, and report against the acceptance criteria you bought to.
01The gap
You can't walk the floor. The ship date doesn't move, and every piece of evidence you have was selected by the party with the most to lose from a finding. A missed hold point and an incomplete record book behave the same way — they stay quiet until release, when the schedule has nothing left to give.
02The method
One controlled sequence, in this order, every job.

04Coverage planning
Criticality decides where an inspector stands.
Equipment type, process step and consequence of failure drive the intervention level — hold, witness, review or monitor — before anyone travels.
05Independence
We work for the buyer. That has rules attached.
- Impartiality and independence
- Work is undertaken without commercial, financial or operational pressure that could compromise objectivity. Conflicts of interest are identified, evaluated and managed.
- Confidentiality
- Client information is not disclosed without authorization, except where required by law, contract or competent authority.
- Controlled release
- No deliverable is released until required verifications are complete, with the authorizing person and applicable revision identified on the record.

08Coverage
Mexico and the United States
Inspectors on both sides of the border, with the right to work in both countries, so the border doesn't land in the middle of your paperwork.
Before you commit, we confirm we can put a qualified person in that specific facility on the date the inspection point falls, and we verify supplier access before travel.
