Market
Fresh yellow onion (bulb onion) in Taiwan is a domestically produced vegetable crop with production concentrated in a handful of counties, and the main domestic harvest moves from earlier northern areas to southern producing belts. The Agriculture and Food Agency (Ministry of Agriculture) reports 2024 planting area around 1,668 hectares with production around 82,185 metric tons, with Yunlin, Pingtung, Changhua, Chiayi, and Kaohsiung as key producing areas. Harvest availability typically starts in December, with regional peak windows including Kaohsiung (around January–March) and Pingtung’s Hengchun Peninsula (around March–May). Taiwan also records seasonal export shipments during the domestic peak season (e.g., exports to South Korea and Malaysia reported by AFA for 2024). Market access and continuity are sensitive to plant quarantine clearance (APHIA) and pesticide-residue compliance under Taiwan FDA standards.
Market RoleDomestic producer with limited seasonal exports
Domestic RoleWidely used culinary vegetable in the domestic market; government and farmer-group programs emphasize storage, grading, and marketing during peak season
SeasonalityDomestic onions are generally marketed from December onward, with early harvest starting in Changhua (Shengang) and later peak harvest in southern production areas; Pingtung (Hengchun Peninsula) is a key late-season supply region.
Risks
Phytosanitary HighMarket entry for fresh onions can be blocked at the border if APHIA quarantine requirements are not met (notably, missing phytosanitary certificates and/or interception of quarantine pests). APHIA quarantine requirements indicate shipments may be destroyed or re-shipped if phytosanitary documentation is not provided, and goods may require quarantine treatment when pests are intercepted.Confirm product eligibility and APHIA import conditions before shipment; ensure the phytosanitary certificate and any required additional declarations match APHIA requirements; implement pre-shipment pest-control and inspection protocols aligned with the exporting NPPO and Taiwan’s APHIA expectations.
Food Safety MediumFresh onions sold in Taiwan must comply with Taiwan FDA pesticide residue limits. Non-compliance can trigger enforcement actions and disrupt distribution or lead to shipment/lot disposition issues.Align pesticide program and pre-harvest intervals to Taiwan FDA residue standards; conduct accredited residue testing for relevant actives prior to shipment and keep complete spray/trace records.
Climate MediumTaiwan’s domestic onion season and supply timing can be disrupted by extreme weather events (e.g., typhoons), which AFA has linked to delays in onion production timing for the following season.Plan procurement with seasonal buffers and alternative sourcing windows; use cold storage and staged releases to smooth domestic supply during peak and post-typhoon periods.

FAQ
Where are Taiwan’s main domestic fresh onion producing regions?Taiwan’s Agriculture and Food Agency (Ministry of Agriculture) identifies major producing areas including Yunlin County, Pingtung County, Changhua County, Chiayi County, and Kaohsiung City. The AFA Southern Region Branch highlights key southern producing districts such as Hengchun, Checheng, and Fangshan in Pingtung, and Linyuan in Kaohsiung.
When does Taiwan’s domestic onion harvest season typically start, and what are key regional harvest windows?The Agriculture and Food Agency notes that onions harvested in Taiwan are generally available starting in December, with early harvest in Changhua’s Shengang area. The AFA Southern Region Branch describes Kaohsiung’s main production period around January–March and Pingtung’s main production period around March–May.
What are the key compliance requirements for importing fresh onions into Taiwan?Taiwan’s APHIA regulates fresh onions as plant products and requires import quarantine inspection at entry. APHIA quarantine requirements state that importers of fresh plants or plant products are required to present phytosanitary certificates issued by the exporting country’s plant quarantine authority, and non-compliance can result in destruction or re-shipment. In addition, Taiwan FDA’s pesticide residue standards apply to foods, so imported onions must meet Taiwan’s pesticide residue limits.
