Vietnam leads Frozen Whole Herring supply with 11.2% of suppliers, followed by Brazil ( 7.4% ) and China ( 6.4% ) — a distribution across three distinct sourcing regions rather than a single dominant origin.

3.1% of all listings were added in the last 30 days, indicating a steady but limited influx of new supply. 49.5% of suppliers were active in the last 90 days, and 65.4% carry business verification — a base that is partially active and a majority has undergone documentation checks.
