Last updated: April 2026 dataPeat occupies a dual commercial role: as a low-grade solid fuel in countries with large bog resources, and as a horticultural growing medium — the latter being the more significant trade flow into the United States. The heading covers both energy-grade peat and peat litter (used as animal bedding), whether loose or agglomerated, reflecting the range of physical forms in which it enters commerce. Importers of horticultural peat should be aware that USDA APHIS may require phytosanitary documentation to address potential pest and weed-seed concerns associated with organic growing media.

USDA APHIS has authority over imported plant-based materials, including peat, due to the potential for soil-borne pests and weed seeds. Importers may be required to provide phytosanitary certificates from the exporting country's national plant protection organization, and shipments may be subject to port-of-entry inspection. Requirements vary by origin country and peat type, so consulting APHIS import regulations before shipment is advisable.
SITC 32230 does not subdivide peat by end use — both fuel-grade and horticultural peat fall within the same heading. The distinction matters commercially and for downstream regulatory purposes (APHIS phytosanitary review for horticultural grades), but the customs classification is the same regardless of whether the peat is destined for combustion or use as a growing medium.
