Last updated: July 2026 dataAnnual and perennial ryegrass seeds are classified to separate US tariff lines (1209250020 and 1209250040) under heading 120925, a distinction that reflects their fundamentally different agronomic roles: annual ryegrass is used primarily for quick-establishing cover crops and winter overseeding, while perennial ryegrass is a staple of permanent pastures and high-wear turf. New Zealand is a globally recognized center of perennial ryegrass breeding and is a leading supplier alongside Canada. USDA APHIS phytosanitary inspection applies at entry, and endophyte status — a fungal symbiont that affects livestock safety — is increasingly specified in commercial contracts for perennial varieties.

Endophyte fungi (Epichloë festucae var. lolii) naturally occurring in perennial ryegrass can cause ryegrass staggers in livestock at high infection levels. While endophyte status is not a CBP classification criterion, it is a critical commercial specification: buyers in pasture markets often require certified low-endophyte or novel-endophyte seed, and this must be documented by the exporting seed company. Importers should request endophyte test certificates alongside phytosanitary documentation.
Annual (Lolium multiflorum) and perennial (Lolium perenne) ryegrass are distinct species that classify to different 10-digit HTS lines. If species identity cannot be confirmed from the exporter's documentation or seed analysis certificate, CBP may require additional evidence or reclassify the entry. Importers should ensure that phytosanitary certificates and commercial invoices specify the botanical species name, not just 'ryegrass.'
