Quick answer: Mangoes enter the United States in the ventilated, single-layer 4 kg (8.8 lb) corrugated carton, sold by count: 6, 7, 8, 9, 10, 12 and 14 fruit per box for Tommy Atkins, Kent and Keitt, and 12 to 22 for Ataulfo. The minimum board documented by the National Mango Board packaging study is C-flute with a 200 lb burst strength. On a 40 × 48 in GMA pallet the two designs in that study load 144 or 195 trays, so a 40 ft container with 20 pallets carries 2,880 to 3,900 trays. Mexico shipped 82.8 million 4 kg boxes to the U.S. in the 2026 season, about 13 % fewer than in 2025 (National Mango Board, September 30, 2026). Printed cartons and PP corrugated plastic harvest crates made in Asia should be confirmed 10 to 12 weeks before the first shipment.

How much packaging the U.S. mango trade moves

Mango is one of the few fruits whose trade volume is published directly in boxes: every week the National Mango Board (NMB) reports how many 4 kg boxes each origin shipped to the United States. For a packaging buyer that figure is the market size, with no tonnes-to-boxes conversion needed.

One NMB box equals 8.8 lb (4 kg). Mexico's Ministry of Agriculture (SADER/Senasica) registered 19,734 orchards in eight states (Colima, Chiapas, Guerrero, Jalisco, Michoacán, Nayarit, Oaxaca and Sinaloa) for the 2026 U.S. programme and projected more than 350,000 tonnes; those figures come from the ministry as reported by FreshFruitPortal on April 13, 2026. A packer handling 1 % of Mexico's volume needs roughly 830,000 to 950,000 cartons per season, plus harvest crates and pallets.

The 4 kg mango box: counts and average fruit weight

Before asking for a price, fix four things: the destination, the variety, the range of counts you will pack, and whether the fruit goes through hot-water treatment. Each answer changes the inside height, the board and the venting.

Count (fruit per 4 kg box)Average fruit weightTypical varietiesBox note
6≈ 665 gRound varieties: Tommy Atkins, Kent, Keitt, HadenTaller inside height (counts 6–9)
7≈ 570 g
8≈ 500 g
9≈ 445 g
10≈ 400 gRound varieties; 12 and 14 also AtaulfoLower inside height (counts 10–14)
12≈ 335 g
14≈ 285 g
16≈ 250 gAtaulfo (honey mango)Flatter, elongated fruit: its own inside height; the yellow skin marks easily, so a smooth interior matters
18≈ 220 g
20≈ 200 g
22≈ 180 g

Average weight is simple arithmetic: 4,000 g divided by the count. Count ranges per variety follow trade practice as documented on our Spanish-language page; each retailer sets its own assortment. The NMB packaging study warns that "a 4 kg tray is impossible to accommodate all varying sizes for the 5-18 count fruit": 5 count fruit is too large to reach 4 kg, and 12–18 count fruit gives almost 5 kg in the larger tray.

Corrugated carton specification for mangoes

UC Davis recommends 13 °C (55 °F) for mature-green mangoes and 10 °C (50 °F) for partially ripe and ripe fruit, at 90–95 % relative humidity, with a postharvest life of 2 to 4 weeks in air. A carton that leaves the packhouse dry therefore spends weeks in humid cold air under a full pallet load. The test that matters is compression strength measured wet, not the dry value printed on most quotations. The method is explained in our banana carton guide (the same humid cold chain).

ParameterWhat to specify for the 4 kg mango cartonBasis
ConstructionOne-piece tray with reinforced corners, open or lidded; one layer of fruitTrade practice
Minimum boardC-flute corrugated, 200 lb burst strength; double wall for long-transit programmesNMB packaging study (minimum for its two tray designs)

Paper and coatingKraft with a moisture-resistant treatment; we recommend wax-free board so the box stays recyclable; smooth interior so the skin is not markedFuxing recommendation
VentilationOpenings on all four faces, aligned between layers so pre-cooling air crosses the pallet. The study found the horizontal side openings more critical for cooling than vertical openings in the tray bottomNMB packaging study
Inside heightTwo heights for round varieties (counts 6–9 and 10–14); a separate height for AtaulfoTrade practice
Pallet securingCorner posts with 10–11 horizontal straps on intermodal shipments from South America; 5–7 straps on truck shipments from MexicoObserved in the NMB study
Print and traceabilityFlexo, 2 to 4 colours: brand, variety, count, net weight, country of origin, packhouse and orchard codes, lot. FSC paper on requestTrade practice

Where single-use board suffers most is inside the packhouse, between the treatment tank, cooling and the packing table. On that internal loop many packers replace it with a 4–5 mm PP corrugated plastic box that absorbs neither water nor latex, is washed and goes back on the line. We compare the cost per trip in PP box vs cardboard, and explain sheet thickness in the corrugated plastic thickness guide.

Hot-water treatment and storage temperatures

Mangoes from Mexico and Central America enter the United States under a quarantine treatment, most commonly the USDA APHIS hot-water dip (schedule T102-a), applied at a certified facility in the country of origin under APHIS monitoring. Fruit must be pre-sorted by weight class; mixed loads cannot be treated. The NMB crop report also notes that late-season Mexican shipments are treated with irradiation instead.

StepConditionSource
Hot-water dip, water temperature115 °F (46.1 °C) or above for the whole treatment; fruit pulp at 70 °F (21.1 °C) or above before startingUSDA APHIS, T102-a (Federal Register, 2003)
Flat, elongated varieties (for example Ataulfo)Up to 375 g: 65 minutes · 375–570 g: 75 minutesSame
Rounded varieties (Tommy Atkins, Kent, Keitt)Up to 500 g: 75 minutes · 500–700 g: 90 minutes · 701–900 g: 110 minutesSame
Hydrocooling after the dipIf hydrocooling starts within 30 minutes of the dip, add 10 minutes to the dip time; hydrocooling water not below 70 °F (21.1 °C)Same
Storage, mature-green fruit13 °C (55 °F), 90–95 % relative humidity; 2–4 weeks in air, 3–6 weeks in controlled atmosphereUC Davis Postharvest Center
Storage, partially ripe and ripe fruit10 °C (50 °F), 90–95 % relative humidityUC Davis Postharvest Center
Controlled atmosphere3–5 % O2 and 5–8 % CO2UC Davis Postharvest Center

The dip times shown are the schedule for Mexico and Central America as published in the Federal Register (proposed January 2, 2003; final rule effective May 23, 2003). Other origins, including South America, have their own tables. Schedules are amended from time to time: always confirm the schedule in force with your APHIS-certified treatment facility. This page is packaging guidance, not phytosanitary advice.

Harvest crates: rigid plastic, cardboard or PP corrugated plastic

Mangoes bleed latex when they are cut from the tree. If fruit comes down from the orchard tightly packed or rubbing, latex and pressure leave marks that the packhouse later downgrades. The package used on that stretch almost never appears in the carton quotation, and it is where premium counts are lost.

OptionCapacity and usual dimensionsAdvantagesLimitsRelative cost per trip
Injection-moulded rigid crate18–22 kg; 530 × 360 × 300 mm or similarVery strong, stackable, washableDoes not fold: the return truck travels full of air; inside edges mark the fruit if overfilledLow if it lasts several seasons; high in return logistics
Single-use corrugated cardboard box10–15 kgNo return, no washingA new box every trip; softens with latex, dew and treatment waterThe highest in programmes with more than 3 trips a week
Foldable PP corrugated plastic box15–20 kg; 600 × 400 × 250–300 mm; 4–5 mm sheetWashed and sanitised, absorbs no latex or water, smooth surface, folds flat to about a quarter of its volume, printed with orchard and lotMust be recovered: needs inventory control between orchard and packhousePays back over tens of trips; after that it costs only the wash

How to specify thickness, sheet weight and static load is in the PP produce box specification template, and the per-trip maths in the harvest bins cost guide. Capacities and dimensions above are typical values from our Spanish-language guide for Mexican packers, not test results; ask for the static load of the exact crate quoted.

U.S. importers of PP corrugated boxes, note: boxes made in our Philippine plant carry 0% U.S. AD/CVD — not 0% import duty; 12.5% Section 301 (since Jul 24, 2026) + normal HTSUS duty, confirm with your broker. Details in PP boxes from the Philippines.

Boxes per pallet and per 40 ft reefer

Mangoes fill the equipment by volume before weight: one layer of fruit per box and generous venting mean the container is full before it is heavy. Every extra layer the carton can carry lowers the freight per kilogram, which is why wet compression strength is a freight question as much as a quality one.

Source: National Mango Board packaging standardization study (Cal Poly / Michigan State University), Table 3; container totals are 20 pallets multiplied by trays per pallet. The study works with a 34,000 lb payload limit for a 40 ft container on a tandem-axle truck. Counted at the 4 kg statistical box, the same loads equal 576–780 kg of fruit per pallet and 11.5–15.6 t per container. For 53 ft trailers the study lowers the 15-down pallet to 12 layers (180 trays, 706 kg). Existing Brazilian and Peruvian pallets observed in the study were 12 per layer and 21 layers high (252 boxes): confirm your own pattern with the usable height of the equipment and the wet compression of your carton.

Ordering calendar by origin

For printed cartons and PP crates made in Asia the arithmetic for Mexico is 1–2 weeks of artwork and samples, 3–4 weeks of factory time, 30–35 days at sea to Manzanillo, Lázaro Cárdenas or Mazatlán and about a week of clearance: 10 to 12 weeks in total. Packers in Peru, Ecuador and Brazil should replace the sea leg with the transit time quoted to their own port.

OriginShipping window to the U.S.Order close (10–12 weeks before first shipment)What is bought

PeruFirst week of October to first week of March (2024–25 season; single trade-press source)Mid-July, adjusted for your transit4 kg cartons for Kent, PP crates

If the order closes late there are two honest ways out: unprinted cartons and standard crates (2–3 weeks of factory time), or consolidating corrugated cartons, PP crates and retail bags in one container so you do not wait for two shipments.

Frequently asked questions

What box is used to ship mangoes to the United States?
The ventilated, single-layer corrugated carton of 4 kg (8.8 lb). It is the unit the National Mango Board uses to count shipments from Mexico, Brazil and Ecuador. Fruit is sold by count, meaning the number of mangoes in the box: 6, 7, 8, 9, 10, 12 and 14 for round varieties such as Tommy Atkins, Kent and Keitt, and 12 to 22 for Ataulfo (honey) mangoes. The minimum board documented in the National Mango Board packaging study is C-flute corrugated with a 200 lb burst strength.
What do mango counts mean and how much does each fruit weigh?
The count is the number of mangoes that fill one 4 kg box, so the average fruit weight is 4,000 g divided by the count: about 665 g for a 6 count, 500 g for an 8, 400 g for a 10, 335 g for a 12 and 285 g for a 14. In Ataulfo, a 16 count is about 250 g and a 20 count about 200 g. Large fruit is also taller, and the National Mango Board study concluded that one 4 kg tray cannot accommodate the whole 5 to 18 count range, which is why packers run two inside heights.
How many 4 kg mango boxes fit on a pallet and in a 40 ft reefer?
On a 40 by 48 inch GMA pallet, the two designs in the National Mango Board packaging study load 144 trays (12 per layer, 12 layers) or 195 trays (15 per layer, 13 layers), with pallet loads of 750 kg and 762 kg. At 20 pallets, a 40 ft container carries 2,880 to 3,900 trays. Counted at the 4 kg statistical box that is 11.5 to 15.6 tonnes of fruit. Many packers stack higher: the study saw Brazilian and Peruvian pallets at 12 per layer and 21 layers, so confirm your own pattern against the usable height of the container and the compression strength of your carton.
How does hot-water treatment affect the mango carton?
Mangoes treated under USDA APHIS schedule T102-a are immersed in water at 115 °F (46.1 °C) or above for 65 to 110 minutes depending on shape and weight, then cooled. Fruit can reach the packing table still damp and warm, and the box then spends 2 to 4 weeks at 10 to 13 °C and 90 to 95 % relative humidity (UC Davis recommendations). That is why the carton should be specified by compression strength measured wet, with moisture-resistant paper and vents aligned between layers, and not by the dry value alone.
Are PP corrugated plastic harvest crates worth it for mangoes?
Yes, when the orchard and the packhouse recover the crate. A foldable PP corrugated plastic box in 4 to 5 mm sheet, 600 by 400 mm, carries 15 to 20 kg of mangoes, does not absorb latex or wash water, can be washed and sanitised, and folds flat to about a quarter of its volume when empty. The smooth surface reduces the rub and latex marks that later downgrade fruit. Against the rigid injection-moulded crate, the return truck does not travel full of air. If crates are not recovered, a reusable crate does not pay.
When should I confirm boxes and crates for the next mango season?
Count 10 to 12 weeks back from the first shipment: 1 to 2 weeks for artwork and samples, 3 to 4 weeks of factory time and 30 to 35 days at sea from Asia to Manzanillo, Lázaro Cárdenas or Mazatlán. For Chiapas and Oaxaca, which open in January and February, the order closes in October and November; for Guerrero, Michoacán, Jalisco and Colima, in December and January; for Nayarit and Sinaloa, in March and April. Brazil starts shipping to the U.S. in the second week of July and Ecuador in the third week of September, so count back from those dates with your own transit time.
