Fresh or Chilled Leeks and Other Alliaceous Vegetables

Line 0703900020 covers green onions of species other than Allium cepa — meaning bunching onions of different botanical species (such as Allium fistulosum) are captured here, while green onions of the common onion species (Allium cepa) would be classified under the onion lines of heading 070310. Botanical species identification is therefore the key classification criterion.

Mexico and Canada dominate supply, and their complementary growing seasons help smooth year-round availability for US buyers. However, leeks are a relatively low-volume, perishable crop, so cold-chain reliability and transit time from each origin are important procurement factors, particularly during peak domestic US production periods when import volumes tend to soften.
