Azuki bean flour is a milled pulse ingredient produced from adzuki bean (Vigna angularis), with the underlying crop and demand base concentrated in East Asia—especially China, Japan, and Korea. In official trade statistics, azuki bean flour is typically not separately identified and is generally captured within HS 110610 (pulse flours), where large-scale exporters and importers reflect broader pulse-flour dynamics rather than azuki-only flows. Upstream dried adzuki bean trade (HS 071332) indicates strong import demand in Japan and Korea and significant export availability from China and Canada, shaping the input economics for flour milling. Market dynamics are influenced by regional confectionery usage (including azuki-based pastes used in wagashi), and by supply risks tied to concentrated production regions and crop health.
Major Producing Countries- 중국Adzuki bean (Vigna angularis) is extensively cultivated in East Asia; China is identified as a leading producer in scientific literature. Azuki-bean-flour supply is therefore highly exposed to Chinese crop availability and internal demand.
- 일본Japan is identified as a leading producer in scientific literature and a major import market for dried adzuki beans; flour use is closely linked to Japanese confectionery applications using azuki (e.g., anko as a key input for wagashi).
- 대한민국Scientific literature describes extensive cultivation in East Asia including Korea; Korea is also a major import market for dried adzuki beans, indicating strong regional demand that can influence availability for milling.
- 캐나다Commercial dry-bean programs in Canada include adzuki (e.g., Ontario); Canada is also a major exporter of dried adzuki beans (upstream input for flour milling).
Major Exporting Countries- 인도Official trade statistics typically aggregate pulse flours (including bean flours) under HS 110610; in this aggregate category, India appears as a leading exporter (azuki-specific flour is not separately identified in HS 110610).
- 캐나다In HS 110610 (aggregate pulse flours), Canada is among leading exporters; Canada is also a leading exporter of dried adzuki beans (HS 071332), supporting potential origin-to-milling supply chains.
- 프랑스In HS 110610 (aggregate pulse flours), France is among leading exporters; this reflects broader pulse-flour trade rather than azuki-specific identification.

Supply Calendar- Temperate production regions (North America):SepAdzuki beans are typically harvested in mid-September in the U.S. Columbia Basin per OSU Extension; similar late-summer/early-autumn timing is common for temperate dry-bean harvests (azuki-specific calendars vary by region).
- Northeast China (primary production areas):Aug, Sep, OctScientific literature identifies northeastern China as primary production areas and notes spring planting; harvest months shown are a model inference consistent with temperate cropping and should be verified with local agricultural calendars.
- Japan (notably Hokkaido production):Sep, OctJapan is identified as a leading producer; harvest months shown are a model inference for temperate Japan and should be verified with Japanese agricultural calendars.
Specification
Physical Attributes- Fine powder derived from cleaned dried adzuki beans; color typically light reddish-brown to tan depending on dehulling/roasting and milling specifications
- Naturally gluten-free pulse flour; hydration and viscosity behavior depend on starch damage level and particle size distribution
Compositional Metrics- Typical buyer specifications include moisture, protein, ash, and fat (as relevant), plus particle size distribution for functional performance
- Food-safety programs commonly include pesticide residue and mycotoxin testing aligned to destination-market requirements
Grades- Food-grade (human consumption) versus non-food/feed-grade distinctions are common in commercial practice; specific grading schemes vary by market and contract
Packaging- Export/industrial formats commonly use multiwall paper bags with inner liners or bulk sacks; retail formats may use sealed pouches for moisture control
- Moisture barrier packaging is important to prevent caking and quality degradation during storage and transit
ProcessingDehulling and/or roasting may be applied to adjust color, flavor, and functional properties before millingHeat treatment (where used) can reduce microbial load but may change flavor and functionality; contracts typically specify whether flour is raw milled or heat-treated
Supply Chain
Value Chain- Adzuki bean procurement (domestic or imported) -> cleaning and optical sorting -> (optional) dehulling -> (optional) roasting/heat treatment -> milling and sieving -> metal detection -> packaging -> export/distribution to food manufacturers
Demand Drivers- East Asian confectionery and bakery applications that use azuki-based ingredients (e.g., azuki paste inputs and related formulations)
- Plant-based and gluten-free product formulation demand for pulse flours where azuki provides distinctive color/flavor and regional authenticity cues
Temperature- Dry, cool, low-humidity storage reduces caking, rancidity risk (if any fat fraction is present), and insect activity; moisture control is typically more critical than refrigeration
Shelf Life- Shelf life is primarily a function of moisture, packaging barrier properties, and pest control; buyers commonly manage with sealed packaging, lot traceability, and periodic quality re-testing during storage
Risks
Supply Concentration HighAzuki bean flour availability is structurally exposed to the adzuki-bean crop, which scientific literature describes as heavily concentrated in East Asia with China and Japan as leading producers; trade data for dried adzuki beans also shows large import dependence in Japan and Korea. Weather shocks or production shortfalls in these key regions can tighten global availability and raise costs for processors that mill azuki flour.Maintain multi-origin procurement strategies for the underlying beans (e.g., combine East Asian and North American suppliers where feasible), pre-qualify substitute pulse flours for non-authentic applications, and use forward contracting plus safety stocks for peak seasonal demand.
Plant Health MediumAdzuki bean is susceptible to multiple viral diseases (reported in scientific literature, including mosaic viruses affecting legumes), which can reduce yields and quality and create sudden supply disruptions for millers relying on specific origins or cultivar performance.Source from suppliers with documented seed health programs, field monitoring, and post-harvest quality controls; diversify suppliers across regions and crop years to reduce single-outbreak exposure.
Food Safety MediumAs a pulse-derived ingredient, azuki bean flour can face trade disruption from non-compliance on contaminants such as pesticide residues and mycotoxins; Codex standards for certain pulses reference these hazard categories and are commonly used as international benchmarks, while destination markets may apply stricter limits.Require lot-level certificates of analysis and residue/mycotoxin test results from accredited labs, implement supplier approval/audits, and ensure traceability plus contaminant controls across storage and milling.
Sustainability- Climate and extreme-weather sensitivity in concentrated East Asian production areas (yield volatility translating into input-cost volatility for flour)
- Pesticide stewardship and residue compliance for pulses and pulse-derived flours in cross-border trade
FAQ
Which HS code is commonly used for pulse flours like azuki bean flour in international trade statistics?Azuki bean flour is typically reported within HS 110610 (flour, meal and powder of dried leguminous vegetables). Many countries do not publish a separate HS 6-digit line for azuki-only flour, so it often appears aggregated with other pulse flours under HS 110610.
Which countries are major global import markets for dried adzuki beans (an upstream input to azuki bean flour)?UN Comtrade-based data (via World Bank WITS) for HS 071332 shows Japan and the Republic of Korea as major import markets, with additional significant imports reported by China and the United States. These bean flows matter because millers can source azuki either domestically or via imports before producing flour.
What international food-safety reference is commonly used for pulse contaminants and hygiene expectations relevant to azuki-derived ingredients?Codex Alimentarius CXS 171-1989 (Standard for Certain Pulses) outlines baseline quality and safety expectations for pulses, including references to compliance with Codex maximum residue limits for pesticides and Codex mycotoxin limits where applicable, alongside hygiene guidance. While azuki bean flour is a processed ingredient, these pulse standards are often used as upstream benchmarks for raw-bean acceptance and risk controls.
