Wholesale Onion Suppliers

India dominates world onion exports at roughly 2.5 million tonnes per year, followed by China, the Netherlands (re-export hub), Egypt, and the USA. Seasonal supply cycles make sourcing strategy critical: Indian exports peak September–March, Dutch exports peak August–February, and Egyptian exports peak February–May. Price volatility linked to monsoon-driven Indian harvest failures makes dual-origin contracts a standard risk-mitigation practice for large buyers.

Yellow/brown onions are the dominant global trade variety, accounting for ~75% of volumes. Red/purple onions command premium pricing in European retail and food-service. White onions are the preferred type in Mexican and US food-service markets. Sweet onions (Vidalia, Walla Walla, Cévennes AOC) occupy a high-value niche. Shallots (Allium cepa var. aggregatum) are traded separately, with French grey shallots fetching the highest premiums. Sizes are graded in 10 mm increments; 40–70 mm is the mainstream export grade.

UNECE Standard FFV-25 defines onion quality classes (Extra, Class I, Class II) covering firmness, shape, colour uniformity, and freedom from rots. EU Regulation 543/2011 implements FFV-25 for market access. US Grade Standards (USDA) specify US No. 1 and US No. 2 criteria. Maximum Residue Limits under EU Reg 396/2005 apply to pesticides including chlorpropham (CIPC, used for sprout suppression in cold store) — buyers sourcing EU-destined onions should confirm CIPC-free storage. GlobalGAP and GRASP certifications are standard for European buyers.

Cured dry onions store optimally at 0–2°C with 65–70% RH for up to 9 months. Controlled atmosphere (1–3% O₂, 5–7% CO₂) extends shelf life further and suppresses sprouting. Sweet onions, with higher sugar content and thinner skins, are far more perishable (2–3 months maximum). Spring/green onions require 0°C, 95% RH, with a shelf life of 3–4 weeks. Fumigation alternatives to methyl bromide (phosphine, sulfuryl fluoride) are required by many importing countries for soil-borne pest quarantine compliance.

Standard bulk export packing: 10, 15, 20, or 25 kg polypropylene mesh bags on pallets. Retail packs (1, 1.5, 2 kg net bags) are prepared at destination pack-houses or at origin for pre-packed retail. A standard 20-ft FCL holds approximately 20–22 tonnes loose-loaded (net); reefer containers are used for sweet and fresh onions. Air freight is not commercially viable for bulk; small consignments of premium sweet onion varieties may use air.

Q: What is the minimum order for wholesale onions? A: Most bulk exporters require 1 FCL (approximately 20 tonnes) as minimum order quantity. Smaller lots (500 kg–5 t) are available from trading companies at higher per-kg cost.

Q: Which onion variety has the longest shelf life? A: Properly cured yellow/brown onions stored at 0–2°C and 65–70% RH can last 9–12 months. Sweet onions and spring onions are far more perishable.

Q: How do I verify CIPC-free storage for EU import? A: Request a declaration from the exporter confirming no chlorpropham was applied during storage. EU Member State official controls test for CIPC residues on arrival.

Q: What certifications should I require from Indian onion exporters? A: APEDA registration (mandatory for Indian agricultural exports), GlobalGAP or equivalent, and a valid phytosanitary certificate from India's Plant Quarantine authorities.

Q: Can I source organic certified onions in bulk? A: Yes. Netherlands, Germany, and India all have certified organic onion producers. Volumes are limited; plan 3–6 months ahead and expect 30–50% premiums over conventional.
