Market
IQF frozen blueberries in the United States are supplied by a large domestic blueberry industry and supplemented by imports; product is sold in retail frozen fruit and as an ingredient to processors/food manufacturers. The U.S. is described by USITC as the world’s largest producer of blueberries and a substantial importer; frozen blueberries are classifiable under HTS subheading 0811.90.20.
Market RoleMajor producer and consumer market; substantial importer; active domestic freezing/processing base
Domestic RoleMainstream retail frozen fruit item and a common ingredient input for food manufacturing (e.g., bakery, dairy, cereal, smoothie/ingredient applications)
SeasonalityDomestic harvest timing varies by region; IQF frozen product is distributed year-round from cold storage and supplemented by imports.
Risks
Food Safety Outbreak HighA viral contamination event in frozen berry supply chains can trigger rapid recalls and public-health response; U.S. authorities linked a 2013 hepatitis A outbreak to a frozen berry mix (Townsend Farms Organic Anti-Oxidant Blend) sold via Costco, illustrating high-consequence recall/outbreak risk in frozen berry products.Use verified suppliers with documented preventive controls and sanitation programs; strengthen supplier verification for high-risk hazards (including viral contamination pathways); maintain rapid lot-level traceability and recall readiness.
Cold Chain Break MediumCold-chain failures (temperature excursions, power outages, prolonged holds) can cause thawing/refreezing and degrade product quality, increasing customer complaints and dispute risk even where food remains microbiologically safe at appropriate frozen temperatures.Implement continuous temperature monitoring, validated reefer setpoints, and contingency plans for storage/transport disruptions (backup power, alternate cold storage, expedited clearance procedures).
Import Compliance MediumU.S. import noncompliance (e.g., missing/incorrect FDA Prior Notice or inadequate FSVP documentation) can lead to detention, refusal, or significant clearance delays that also increase cold-chain risk exposure for frozen shipments.Align broker, importer, and supplier on an entry checklist covering Prior Notice, importer identification, and FSVP responsibilities; pre-validate documentation and records availability before sailing/dispatch.
Labor Heat MediumHarvest labor constraints and worker-safety incidents (notably heat exposure during field work) can disrupt picking schedules and raise compliance and reputational risk for berry supply chains.Require heat illness prevention programs for field operations (water/rest/shade, acclimatization, training) and audit labor compliance where seasonal/H-2A labor is used.
Labor & Social- Seasonal farm labor reliance creates compliance risk exposure (wage/working-conditions scrutiny), including where H-2A temporary agricultural workers are used
- Occupational heat exposure is a material worker-safety risk for outdoor harvest operations; OSHA highlights heat illness prevention and related enforcement focus

FAQ
How are IQF frozen blueberries typically processed in U.S. facilities?A common workflow is receiving and inspecting fruit, rinsing/cleaning, additional inspection/sorting, then IQF freezing (e.g., a freeze tunnel) followed by bulk packing and optional re-packing for private label or industrial customers.
What are key U.S. entry compliance items for imported IQF frozen blueberries?FDA requires Prior Notice for imported foods and, for covered importers, a Foreign Supplier Verification Program (FSVP) to verify suppliers meet applicable U.S. food safety requirements. Shipments may be screened or examined in coordination with CBP.
What is a high-consequence food-safety risk for frozen berry products in the U.S. context?Viral contamination events can trigger rapid recalls and public-health response; in 2013, authorities linked a hepatitis A outbreak to a frozen berry mix (Townsend Farms Organic Anti-Oxidant Blend) sold via Costco.
What HTS category does USITC identify for frozen blueberries and what did it report about the duty rate?USITC identifies frozen blueberries under HTS subheading 0811.90.20 and reported that the 2021 general rate of duty for 0811.90.20 was free (confirm current HTS and any origin-specific additional duties at time of import).
