Tree Nut Industry Statistics

GITNUXREPORT 2026

Tree Nut Industry Statistics

Tree Nut Industry numbers run from allergy prevalence to trade and retail momentum, including $5.0 billion-plus U.S. almond sales in 2023 and $2.0 billion-plus pistachio sales, alongside FDA and EU allergen rules that hinge on clear labeling and strict contaminant limits. You will see why pistachios can be shellable and highly traded while consumers remain highly label focused, plus how processing standards and FSMA preventive controls shape what makes it from kernel to shelf.

Single source

Cost Analysis Interpretation

For the cost analysis of tree nut processing in the U.S., energy expenses are a clear pressure point because 2022 manufacturing energy prices rose 6.8% versus 2021 and industrial costs averaged 10.79 cents per kWh and $6.55 per MMBtu for natural gas, even as processors still need to hit tight roasting and pasteurization targets like hazelnuts aiming for 2% to 4% final moisture and almonds requiring validated heat treatment under FSMA.

Directional

Regulation & Compliance Interpretation

Regulation and compliance around tree nuts is especially demanding because 40% of European consumers report always reading food labels while EU and US frameworks mandate strict allergen labeling for tree nuts and set tight aflatoxin limits up to about 10 to 15 µg/kg, alongside FSMA preventive controls that require processors to account for allergen and pathogen hazards.

Quality & Safety

1FDA reported that recalls involving nuts/seed products are recurring categories within its recall database search results, indicating sustained enforcement/quality monitoring (recall frequency for nuts and nut products).[35]
Verified
2Heat treatment and roasting can reduce microbial loads in nuts; a peer-reviewed study measured reductions in Salmonella on pistachio kernels after controlled roasting (experimental intervention).[36]

4In the EU, rapid alert system notifications related to food and feed include multiple nut-related entries for contaminants/allergens; nut categories appear repeatedly in annual reports (category frequency across years).[38]
Verified

Quality & Safety Interpretation

Across quality and safety signals, nuts repeatedly show up in enforcement and contamination control efforts, with FDA noting recurring recalls for nut products and peer reviewed research confirming that roasting can cut Salmonella on pistachios and detoxification approaches can reduce aflatoxin levels, while the EU rapid alert system and annual reports also list nut related entries year after year.

Supply & Trade

11.4 million tonnes of almonds were exported globally in 2022 (export volume estimate from UN trade flows for almond HS080212/080211 categories aggregated).[39]
Single source

Supply & Trade Interpretation

With about 1.4 million tonnes of almonds exported worldwide in 2022, the supply and trade picture shows a substantial and steady global flow in the almond segment, underscoring the scale of international market activity for tree nuts.
