Last updated: August 2026 dataUnrooted cuttings, rooted slips, and live plants not captured by more specific SITC headings — along with mushroom spawn (inoculated substrate used to propagate edible or commercial fungi) — share this residual classification. USDA APHIS regulates all live plant material at the border, and many genera require an import permit in addition to a phytosanitary certificate from the exporting country. Mushroom spawn presents a distinct biological profile from ornamental cuttings and may be subject to separate admissibility determinations based on the fungal species involved. Admissibility and classification are complex; consult a licensed customs broker or USDA APHIS before importing.

Not necessarily. Mushroom spawn — inoculated grain or substrate carrying fungal mycelium — is evaluated by APHIS under different biological risk criteria than vascular plant cuttings. Importers should contact APHIS Plant Protection and Quarantine to determine whether a specific spawn product requires a permit, and whether the fungal species is subject to any quarantine restrictions.
Cuttings and slips are vegetative propagules — sections of stem, leaf, or root taken for rooting — while finished live plants have an established root system. Both fall under this heading when not covered by a more specific SITC code, but the distinction can matter for phytosanitary treatment requirements and for certain HTS tariff lines at the 10-digit level.
