Heading 2309 covers preparations used in animal feeding, and the first split inside it is between dog and cat food put up for retail sale, 2309.10, and everything else, 2309.90. The difference is not the recipe. It is the presentation: the retail heading is for food packaged and labeled for sale to the pet owner, in the bag or the can the owner buys.
Bulk food, food sold to a kennel or a farm in a sack with no retail labeling, and food for animals other than dogs and cats all fall to 2309.90. The same kibble in two different bags can sit in two different subheadings, and the duty follows the bag. The classifier who reads the recipe and ignores the packaging has the classification backwards.
The trap in pet food classification is the functional ingredient. A treat with a probiotic, a joint supplement, or a medicinal claim stops being food in the classifier's eyes and starts looking like a medicament. Chapter 30 covers medicaments, and a product that presents itself as treating or preventing a condition can be pulled out of Chapter 23 entirely.
The line is the claim, not the ingredient alone. A probiotic added for gut health, with the benefit printed on the front of the pack, is a different classification problem from the same probiotic added as a general nutritional ingredient with no claim. The label is evidence, and CBP reads it. A brand that prints a health claim on the pack has made a classification argument, whether it meant to or not.
The AAFCO nutritional adequacy statement, the line on the pack that says the food is complete and balanced for a life stage, is the standard the US pet food industry uses, and it influences classification because it describes the product's purpose. A food with a full adequacy statement is plainly food. A product without one, marketed as a supplement or a topper, is a harder case.
The statement does not decide the heading on its own. It is one piece of evidence among several: the packaging, the labeling, the claims, and the actual composition. But a classifier who ignores it is missing the document the industry itself treats as the definition of the product, and CBP will ask about it.
Pet food imports are subject to FDA Prior Notice, and it is the filing that gets forgotten most often. The notice has to be filed before the food arrives, with the manufacturer, the product, and the shipment details, and a shipment without it can be held. The classification and the Prior Notice are separate obligations, and getting the heading right does not satisfy the FDA.
File the notice with the classification in hand, because the two documents describe the same product. A product described as a medicament in one filing and as pet food in the other is a contradiction, and contradictions are what get shipments held. The paperwork should tell one story.

Dog and cat food put up for retail sale classifies under HS 2309.10, and in the US under HTS 2309.10.0040. Bulk or non-retail pet food, and food for other animals, falls to 2309.90. The split turns on packaging and presentation, not the recipe.
Yes, if it presents itself as treating or preventing a condition. A treat with a probiotic or joint supplement and a health claim on the label risks reclassification from Chapter 23 to Chapter 30. The claim on the pack is the evidence, and CBP reads it.
It is the nutritional adequacy statement on the pack, saying the food is complete and balanced for a life stage. It describes the product's purpose and influences classification, because a food with a full adequacy statement is plainly food. It does not decide the heading on its own, but CBP will ask about it.
Yes. Pet food imports are subject to FDA Prior Notice, filed before the food arrives, with the manufacturer, product, and shipment details. A shipment without it can be held. The notice and the classification are separate obligations, and both have to describe the same product.
