About HTS 2309.90.70.00
HTS code 2309.90.70.00 classifies imports of: Preparations, with a basis of vitamin B12, for supplementing animal feed. This line sits within Chapter 23 (Flours, meals and pellets, of meat or meat offal, of fish or of crustaceans, molluscs or other aquatic invertebrates, unfit for human consumption; greaves (cracklings):), Section IV (Prepared Foodstuffs; Beverages, Spirits; Tobacco), and is catalogued as a tariff line in the USITC 2026 Basic Edition. Duty is calculated against units of quantity: kg. Getting the classification right is the single most important step in import compliance — a wrong code can mean overpayment of duty, shipment delays, or penalties at the border.
The general (MFN / Column 1 General) rate for HTS 2309.90.70.00 is 1.4%, which applies to most trading partners of the United States. A special preferential rate of "Free (A,AU,BH,CL,CO,D,E,IL,JO,KR,MA,OM,P,PA,PE,S,SG)" may reduce or eliminate duty when goods qualify under a free trade agreement such as USMCA, CAFTA-DR, or one of the bilateral FTAs. The Column 2 rate of 20% applies to imports from non-MFN countries such as Cuba and North Korea — a much higher historical "full" tariff.

Beyond the published rate, importers should check for Section 201 safeguards, Section 301 China tariffs, and any active AD/CVD orders that can materially change the real landed cost. Always verify the classification with a licensed customs broker before committing to a supply contract — this page is a research tool, not a customs ruling.
