Last updated: July 2026 dataTariff-rate quota treatment governs most commercial butter imports into the US, with the schedule splitting entries across three 10-digit lines: 0405100000, 0405101000 (subject to Additional US Note 6 to Chapter 4), and 0405102000 for residual quantities. New Zealand and Ireland are the dominant suppliers, reflecting the competitive cost structure of grass-fed dairy systems in both countries, while France rounds out the top three with premium cultured-butter products. All imported butter must clear FDA oversight as a dairy food and is subject to standard dairy admissibility requirements at the port of entry.

Butter imports are split between in-quota and over-quota tariff lines. Shipments qualifying under Additional US Note 6 to Chapter 4 enter at the in-quota rate (0405101000), while quantities exceeding the TRQ threshold fall under the NESOI line (0405102000), which carries a significantly higher over-quota duty. Importers must track quota fill levels and obtain any required import licenses before shipment.
Commercial butter imports generally require a customs entry, a certificate of origin, and compliance with FDA food facility registration requirements. For TRQ-eligible shipments, an import license or permit issued under the relevant quota administration program is also required. Working with a licensed customs broker familiar with Chapter 4 dairy quotas is strongly advised given the complexity of the additional US notes.
