Clementines have their own subheading (080522), while mandarins, tangerines, and satsumas fall under 080521, and Wilkings and similar citrus hybrids go under 080529. Classification depends on the specific variety; importers should ensure that commercial invoices and phytosanitary certificates accurately identify the citrus type to avoid misclassification.

USDA APHIS imposes origin-specific restrictions related to quarantine pests including citrus greening (Huanglongbing), Mediterranean fruit fly, and citrus canker. Depending on the origin country and pest status, shipments may require treatment, additional inspection, or may be subject to import prohibitions for certain varieties. Importers should consult current APHIS regulations and work with a licensed customs broker to confirm admissibility before contracting shipments.
