Conclusion of: Cashew Processing
What U.S. buyers need from cashew processing today
For U.S. buyers, cashew processing is no longer just about cracking shells—it’s about verifiable quality grades, food safety controls, and packaging that protects flavor across long supply chains. Importers must align plant practices overseas with U.S. expectations on moisture, grading, allergen labeling, and the FDA’s Foreign Supplier Verification Programs (FSVP). FSVP overview (FDA)
From orchard to kernel: a quick map of cashew processing
Before a kernel ever reaches a roaster, cashew processing moves through a predictable chain: raw cashew nut (RCN) drying and storage, heat treatment to loosen shells, decortication (shelling), drying, peeling, grading, optional roasting/seasoning, and protective packing for export. This sequence reduces damage, controls moisture, and sets the stage for clean, uniform lots. Small-scale Cashew Processing (FAO)
Drying and storage: the foundation of reliable cashew processing
Good drying and cool, pest-free storage are the foundations of cashew processing because they stabilize moisture, curb mold risk, and keep shells cracking cleanly later. Processors typically sun- or kiln-dry RCN and store off the floor with ventilation and pest control to preserve kernel quality prior to heat treatment. FAO technical guide
Heat treatment for shell removal: why steaming or oil-bath matters
In cashew processing, steaming or oil-bath roasting makes shells brittle and loosens skins so kernels can be extracted intact. This step also manages the naturally caustic cashew nut shell liquid (CNSL) that can irritate skin and equipment, which is why carefully controlled time/temperature and safe handling are standard. CNSL hazards & handling (Feedipedia)
Shelling/decortication: maximizing whole kernels in cashew processing
Mechanical or manual shelling is central to cashew processing economics because whole kernels command premium prices. Pre-steamed or oil-roasted nuts are split with knives or machines; the goal is high throughput with minimal splits, followed by cooling and intermediate drying to set structure before peeling. UNIDO cashew basics
Peeling and final drying: getting kernels ready to grade
After shelling, cashew processing continues with testa (skin) removal—often by gentle abrasion after brief re-humidification—then final drying to a stable moisture. Drying improves crunch, reduces microbial risks, and helps kernels withstand transport without clumping. FAO process steps
Grading: the language of trade in cashew processing
Standardized grades keep cashew processing transparent for contracts and claims. U.S. buyers commonly reference AFI and UNECE standards, which define quality classes (e.g., Fancy/First Quality) and defect tolerances (e.g., limits for insect damage, mold, foreign matter, scrapes, and scorched tips), with sampling plans embedded for fair inspection. AFI Specifications for Cashew Kernels
Size counts (W180, W210, W240, W320) and pieces: what the codes mean
Because kernel size influences consumer appeal and throughput yield, cashew processing applies size designations such as W180 (large), W240, and W320 (popular retail size). These codes correspond to approximate kernels per pound or kilo; contracts also specify tolerances for smaller sizes and pieces to protect appearance and value. AFI size and tolerance tables
Moisture targets: the 3–5% sweet spot in cashew processing
To maintain texture and prevent clumping or mold, cashew processing targets low, stable kernel moisture. Trade standards specify about 3–5% moisture for kernels shipped in hermetic packs—tight enough to resist rancidity and blocking, yet safe for roasting performance later. UNECE DDP-17 (Cashew Kernels)
Roasting for consumers: oil vs. dry roast in cashew processing
Many U.S. retail products are roasted post-import, but the fundamentals are set during cashew processing. Oil roasting delivers a characteristic color and crunch; AFI’s roast test uses clean vegetable oil at about 149°C (300–310°F) to assess evenness and classify appearance defects, while dry roasting provides a clean-label alternative. AFI Appendix: roast test & limits
Food safety programs (GMPs and metal detection) embedded in cashew processing
Modern cashew processing plants formalize CGMPs, allergen controls, sanitation, and foreign-matter prevention (sieves, magnets, metal detectors/X-ray) as part of a documented food safety management system, supporting audits and importer verification. Cashew FSMS Guide (ComCashew/GIZ)
Packaging that protects: vacuum, nitrogen and hermeticity
Because oxygen and moisture drive rancidity, cashew processing finishes with hermetically sealed, oxygen-barrier packaging. AFI requires leak-proof, lead-free, airtight containers without paper liners; common options are vacuum tins or high-barrier pouches, often flushed with inert gas before boxing and palletizing. AFI packaging requirement
Standard export pack sizes U.S. buyers expect
To streamline logistics, cashew processing typically offers two standard net weights: two vacuum tins of 25 lb (11.34 kg) per carton, or a single 50 lb (22.68 kg) vacuum pouch per carton—formats that balance stackability, barrier performance, and ease of inspection at destination. Typical 2×25 lb or 1×50 lb export packs
Shelf life and storage: keeping flavor locked in
Smart cashew processing pairs barrier packaging with cool, dry storage and first-in-first-out rotation to slow oxidation. Research across nuts shows that high-barrier laminates, vacuum or nitrogen atmospheres, and low humidity reduce peroxide formation and maintain sensory quality over time. Vacuum & high-barrier benefits
U.S. import compliance: FSVP is the rulebook for cashew processing
For every line entry, cashew processing must be backed by the importer’s FSVP activities—hazard analysis (e.g., allergen, rancidity, foreign matter), supplier approval, verification (such as certificates, audits, or testing), and recordkeeping, with a recognized Unique Facility Identifier (e.g., DUNS) at entry. FSVP key requirements (FDA)
Allergen labeling: how cashew processing interfaces with U.S. labels
Because tree nuts are major allergens, retail packs derived from cashew processing must declare the specific nut (e.g., “Contains: Cashew”) under FDA rules. FDA’s 2025 guidance clarifies which tree nut species require declaration; cashew remains on the list alongside almond, pistachio, walnut, etc. FDA allergen labeling FAQ
HTS classification and paperwork to align with cashew processing
Commercial documents for cashew processing should cite the correct Harmonized Tariff Schedule code for shelled cashew kernels (HTSUS 0801.32.00) and include lot codes, origin, grade, net weight, and importer details to speed clearance. Duty treatment varies, so buyers should confirm current rates directly. USITC HTS search (Chapter 8)
Quality assurance checklist U.S. importers can require
To keep cashew processing aligned with specifications, importers often require pre-shipment sampling plans, moisture verification (e.g., AOAC methods), aflatoxin screening where relevant, a roast test for appearance, metal detection results, and sealed reference samples to expedite any claims. AFI sampling & roast test
By-products and sustainability inside cashew processing
Modern cashew processing valorizes by-products: CNSL is a valuable feedstock for resins and coatings, while shells can fuel boilers. Optimizing CNSL extraction conditions and safe handling mitigates hazards and adds revenue for processors. CNSL extraction science
Spec language your contracts should include
To translate cashew processing into enforceable trade terms, contracts should name the grading standard (e.g., AFI or UNECE), grade and size (e.g., W320 Fancy), moisture max (e.g., ≤5%), packaging type (e.g., 2×25 lb vacuum tins; hermetic), pallet config, QA tests (roast test, foreign-matter, metal detection), and FSVP documentation responsibilities.

Troubleshooting common complaints in cashew processing
When buyers report uneven color after roasting, blocking, or off-flavors, root-cause work in cashew processing often points to moisture creep, too-tight vacuum at high moisture, oil deterioration during oil roast, or oxygen ingress in transit—each solved by moisture checks, proper roast oil turnover, and verified high-barrier seals. AFI defect definitions & remedies
Procurement tips to get the best from cashew processing
For dependable supply, align sourcing calendars with harvest, diversify origins, and validate cashew processing partners with third-party audits, COAs, and pilot shipments. Specify inspection at loading, tamper-evident seals, and temperature/humidity data loggers for longer voyages to protect quality on arrival. AFI food standards hub
Final thought
When suppliers follow recognized standards and document every step, cashew processing delivers consistent grade, safe product, and a clean roast—exactly what U.S. brands and consumers expect. Aligning specs with AFI/UNECE and verifying under FDA FSVP closes the loop from farm to shelf. Close the loop with FSVP
