Market
Fresh quince in the United States is a niche pome-fruit market with limited commercial production; UC ANR notes commercial production in California’s Central Valley where irrigation is required. Domestic availability can be supplemented by imports, where market access depends on USDA APHIS country- and commodity-specific requirements in the ACIR database and, where applicable, required phytosanitary treatments. Importers are also subject to FDA import controls, including Prior Notice submissions and (when applicable) FSMA Foreign Supplier Verification Programs (FSVP) requirements. Postharvest handling is quality-sensitive because quinces bruise easily and benefit from defined cold-storage conditions for longer holding.
Market RoleDomestic consumer market with limited commercial production; imports can supplement availability under APHIS/FDA import controls
Domestic RoleSpecialty/niche fresh fruit supplied by limited domestic orchard production and distribution through specialty produce channels
SeasonalityUC ANR notes quince harvest timing is similar to European pear; timing varies by orchard and region.
Specification
Physical Attributes- Change of skin color from green to yellow is cited as a primary maturity index
- Bruising sensitivity is highlighted; careful handling is required
Compositional Metrics- Astringency is associated with high tannin content; quinces are commonly used for cooking/processing rather than eaten fresh
Supply Chain
Value Chain- Domestic (California): orchard harvest → sorting/packing → cold storage → regional distribution
- Imported: origin packhouse → refrigerated transport → U.S. entry processes (APHIS/FDA workflows) → importer distribution
Temperature- Optimum storage temperature is reported as 0°C (32°F)
- Optimum relative humidity is reported as 90–95%
Atmosphere Control- Ethylene treatment (reported at 100 ppm for 2 days at 18–21°C with high RH) can be used after cold storage to stimulate more uniform/faster ripening before processing
Shelf Life- Storage potential is reported as 2–3 months under optimum cold storage conditions
Risks
Phytosanitary Market Access HighFor shipments into the United States, fresh quince market access can be blocked if the commodity is not authorized for the origin country/production area or if required APHIS conditions (including any mandated treatments) are not met as specified in USDA APHIS ACIR and related import controls.Check USDA APHIS ACIR for the exact commodity + origin requirements before shipment; align NPPO-issued documentation and any treatment records to the ACIR conditions and port-of-entry handling plan.
Food Safety Compliance MediumInadequate or incorrect FDA Prior Notice submissions can lead to holds/refusal at the port of entry, and importers covered by FSMA FSVP face compliance risk if verification records are incomplete during FDA review.Build a pre-shipment compliance checklist covering Prior Notice pathway (CBP interface vs PNSI), timing by transport mode, and FSVP record readiness (hazard evaluation/supplier approval/verification activity records as applicable).
Postharvest Quality MediumFresh quince quality is sensitive to bruising and cold-chain breaks; postharvest decay risk can drive commercial rejection and claims in U.S. distribution.Use careful harvest/packing practices to minimize wounding, cool promptly, and maintain the recommended cold-storage setpoints through distribution.
Climate MediumDomestic supply risk is elevated where production is irrigation-dependent and exposed to drought variability, which can tighten availability and increase procurement volatility.Diversify sourcing windows (domestic + import programs where authorized) and monitor drought conditions and water supply indicators relevant to California production areas.
Sustainability- Irrigation dependence for commercial quince production in California’s Central Valley increases exposure to drought and water-supply variability
FAQ
Where is quince grown commercially in the United States?UC ANR notes that quince is grown commercially in California’s Central Valley, where irrigation is required.
What is the main deal-breaker for importing fresh quince into the U.S.?USDA APHIS import eligibility and any required conditions (including treatments) are set by commodity and country of origin in the APHIS ACIR database; if the origin program is not authorized or the requirements are not met, the shipment’s entry can be blocked.
What cold-storage conditions are commonly cited for holding fresh quince longer?UC Davis’ postharvest guidance reports an optimum storage temperature of 0°C (32°F) with 90–95% relative humidity, with storage potential reported as 2–3 months under optimum conditions.
