It can be, if the procedure is the company's own method rather than a restatement of public guidance, the employee's knowledge of it is special or advanced, and the US assignment depends on that knowledge. General cold-chain competence, however strong, is not specialized knowledge; the case rests on what is particular to the company.
Draw the line between the company's method and the industry's goals
The officer will accept that cold-chain integrity matters and will then ask what this employee knows that a well-trained hire could not learn quickly. Answer with specifics: the procedure's decision tree for classifying an excursion by duration and temperature band, the customer-specific release thresholds negotiated into contracts, the logger-data reconstruction method that ties the warehouse management system to the trailer telemetry, and the escalation matrix that determines who is notified within what interval. Then show the employee's relationship to that method: she authored the current revision, she has run the investigations that produced the case history the procedure now relies on, and she is one of the few who can approve a release.
Avoid the phrase 'industry best practice' anywhere in the petition; if the method is best practice, it is not the company's. A knowledge that is both specific to the company and advanced in the employee is the combination the category describes.
