I noticed the half empty bottle also and did a little detective work, according to his feedback profile the seller purchased 32oz Tip 'N Pour Measuring Bottles to sell 16oz of Azoxy 2SC - definitely a marketing error or he changed his mind on what quantity to sell after he purchased the bottles. I assume he has the Azoxy 2SC in bulk like 5-gallon buckets or a larger container. The seller is away until Sep 12, 2022, and I will contact him about the Azoxy 2SC origin etc.
Found another Azoxy product: Azoxy 50 WDG Select, ACTIVE INGREDIENT: Azoxystrobin 50%, $77.26
