No. A trade qualification is general skill available in the labour market. Specialized knowledge must be knowledge of the employer's own product, processes or procedures that is not commonly held.
The ticket gets him in the door; the company's system is the case
Hypothetical example: the petition's first draft leads with the applicant's Red Seal certification and twelve years in the trade. That is the wrong emphasis, because any U.S. electrical contractor could supply those. The case rests on what he knows about this company's controller: the configuration sequence for each firmware branch, the moisture-sensor calibration method the company developed and has not published, the integration quirks with particular dryer models, and the service history that tells him what fails and why. Each of those should be tied to evidence: the internal procedure he follows, the training he received and delivered, the list of installations he commissioned. Then show that the knowledge is not widespread in the company, for instance that two of nine technicians have commissioned the current generation. The trade certification remains relevant to show he can lawfully do the electrical portion where state rules require it, but it is context, not qualification.
Hypothetical example: a water-treatment membrane supplier wants to transfer the technician who knows its proprietary cleaning sequence, but the U.S. affiliate also employs several experienced operators. At intake, identify precisely what the technician knows that the operators do not: internal failure codes, sequencing decisions, or product-specific testing. Compare the transferee with the employer's own staff, not with an imagined average worker. Training records, controlled manuals, and a manager's explanation of the learning path can settle the point. The petition weakens if it describes ordinary industry knowledge as secret simply because the applicant performs it well. It also needs the qualifying year abroad within the preceding three years and a role that actually requires that specialized knowledge.
