K210422 is an FDA 510(k) clearance for the INTAI Surgical Mask (non-sterile). Classified as Mask, Surgical (product code FXX), Class II - Special Controls.

Submitted by Intai Technology Corp. (Nantun Dist., TW). The FDA issued a Cleared decision on March 30, 2022 after a review of 412 days - an unusually long review period, suggesting complex equivalence evaluation.

This device falls under the General Hospital FDA review panel, regulated under 21 CFR 878.4040 - the FDA general hospital device framework. The Traditional 510(k) pathway establishes clearance through substantial equivalence to a legally marketed predicate device, without requiring clinical trial data.

Device pattern: High-complexity regulatory submission. Elevated predicate reliance profile. The extended review timeline suggests the FDA required additional documentation before confirming substantial equivalence - a pattern common in complex or first-of-kind General Hospital submissions.
