STEP - (1): Registration, Traceability & Compliance Layer
At the relevant authority, department(s).
Authority, Department Alignment:
APEDA / NPPO (India)
USDA-APHIS (USA)
Control:
Maintenance, Supervision, Renewal of Registration, Examinations:
All Orchids, Farms, Packhouses, IFC, Exporters, etc. supply chain entities undergo mandatory processes of Maintenance, Supervision, Renewal of Registration (License), Examinations, etc. applicable to the entity at regular span or time (periodically).
Modification and updates are also made as per the importing country's updated norms, periodically.
STEP - (3): Export Lot Creation & Inspection
STEP - (4): APEDA-Registered Packhouse Processing includes :: Pre-Treatment Handling (MANDATORY BASE FLOW)
o Non-exportable fruits are removed at each step, ensuring the super-fine, premium quality mangoes pass the Phyto Sanitary examination and overseas importers, and their consumers receive rejection-free, ultra-premium quality mangoes.
STEP - (5): 🔥 HOT WATER TREATMENT (HWT — PRE-TREATMENT STAGE)
ACTUAL INDUSTRY EXECUTION (INDIA → USA EXPORT FLOW)
To execute a highly profitable, zero-decay supply chain into the United States, A-1 Overseas engineers both aesthetic perfection and transit survivability at the packhouse level.
To protect importers’ retail margins, A-1 OVERSEAS executes a highly calibrated Hot Water Treatment (HWT) as a mandatory, prophylactic pre-conditioning step strictly before the fruit is moved to the USDA-APHIS irradiation facility (IFC).
5.1: Here is our exact, micro-level fungicidal sequence executed in the HWT Process before US pre-clearance:
a. Precision De-sapping & Alum Wash
· The Process: Mangoes are placed on specialized desapping racks (pedicel downwards) and meticulously washed in a calibrated 0.1% to 0.5% Alum or Lime solution.
· The Value Addition: Instantly neutralizes highly acidic mango sap, preventing latex burns (black streaks) and preserving the flawless golden epicarp demanded by premium US retailers.
b. Thermostatically Controlled Hot Water Immersion
· The Process: Desapped fruit is submerged in an APEDA-approved, continuous-hot-water-flow in the HWT plant using automated, conveyor-driven immersion.
· The Exact Parameters: Water temperature is strictly maintained at 52°C (125.6°F) for exactly 3 to 5 minutes.
· The Scientific Reasoning: 52°C is the thermal death point for Colletotrichum gloeosporioides (Anthracnose) and Lasiodiplodia theobromae (Stem-end rot) spores. The 3 to 5-minute duration neutralizes surface fungi without allowing heat to reach the mesocarp (pulp), entirely preventing heat scalding.
c. Rapid Hydro-Cooling (The Thermal Shock)
· The Process: The exact second HWT concludes, mangoes are automatically conveyed into a hydro-cooling bath maintained at 20°C to 22°C for 5 to 10 minutes.
· The Value Addition: This creates an instant thermal shock, arresting internal heat conductivity. Without hydro-cooling, the mango's core temperature would continue rising, causing internal pulp breakdown (jelly seed) during the 14,000 km air transit.
d. High-Velocity Air Drying
· The Process: Post hydro-cooling, fruit passes beneath high-velocity blower fans in a humidity-controlled tunnel for 10 to 15 minutes.
· The Scientific Reasoning: Fruit must be 100% dry before being packed into USDA-compliant 30-mesh cartons. Residual surface moisture inside air-cargo packaging creates a micro-climate that promotes severe bacterial bloom.
e. Bypassing Artificial Waxing (The USDA Advantage)
· The Operational Reality: Applying artificial carnauba wax seals the mango's lenticels (pores). During the subsequent USDA-APHIS Irradiation, this wax barrier traps metabolic CO₂ inside the fruit, causing catastrophic internal fermentation. A-1 Overseas strictly bypasses waxing to ensure flawless irradiation compliance and a premium, natural matte finish.
5.3: Purpose of HWT (USA Export Alignment) before Irradiation Treatment:
Pre-conditioning before irradiation
Surface pest load reduction
Improves dose penetration uniformity (400 Gy)
Reduces risk of:
5.4: Critical Control during HWT Treatment:
5.5: Post-HWT Re-Sorting (CRITICAL CONTROL POINT)
· Re- Sorting & Grading after HWT
Removal of the following fruits post-HWT before packing into the export boxes to pass the Irradiation Treatment:
heat-stressed fruits
softened fruits
damaged, stained fruits.
Weighing of fruits.
Packing of mango fruits in Mango EPE Fruit Foam Net
Packing inside boxes as per USA norms, & Coding/Labelling on the boxes.
Export lot stabilization
Uniformity ensured before irradiation
STEP - (6): Mandatory Irradiation Program & Treatment Dose (The Operational Bottleneck) The Critical Compliance Step
6.1: IFC (Irradiation Facility Center) Facility Transfer:
The packed boxes are transported to high-tech, government-approved, USDA-APHIS-Registered & Approved irradiation facilities in Maharashtra:
(a) Vashi (Navi Mumbai)
(b) Lasalgaon (Maharashtra)
These facilities operate under the supervision of USDA-APHIS Officers during the mango export season.
6.2: Pest Sterilization at these facilities:
The USA [USDA-APHIS] mandates:
The USA mandates that Indian mangoes be exposed to a precise irradiation dose (typically 400 Gray) to neutralize any microscopic quarantine pests without affecting shelf life or flavor so that Pest Sterlization is achieved before exporting this cargo to the USA.
6.3: Irradiation Dose: Minimum 400 Gy (Gray)
(a) that Indian mangoes be exposed to a precisely controlled irradiation dose typically around 400 Gray to 1000 Gray. Mangoes to be exported to the USA must receive a minimum absorbed dose of 400 Gray.
(b) to neutralize any microscopic quarantine pests (Mango fruit fly, Mango seed weevil, etc.) inside mango fruits,
(c) without affecting the fruit quality, taste, shelf life, flavor of the fruit.
(d) Usually, 750 Gray Irradiation Dose is given to the mangoes.
6.4: Irradiation Source (What exactly is used as Irradiation to treat mangoes inside the irradiation chamber?) :
The process typically uses Cobalt-60, a gamma radiation source, at irradiation certified facilities (IFC).
6.5: Irradiation Facility Certification/Registration:
The Irradiation Treatment on Mangoes must occur at an irradiation facility approved, registered by both the Agricultural and Processed Food Products Export Development Authority (APEDA) in India and USDA-APHIS.
6.6: A-1 Overseas Execution:
Because irradiation treatment facility capacity is strictly limited during peak season, securing these treatment slots is the most critical operational step in export planning. We lock in seasonal allocations in advance to prevent delays in the USA-bound mango export shipments.
6.7: Where the irradiation-treatment requirement originally comes from:
The irradiation treatment requirement is defined, generated, and governed by the USDA Animal and Plant Health Inspection Service (APHIS) and the irradiation treatment scheduled under APHIS Treatment Manual — Schedule T105-a
6.8: Official USDA Regulatory Basis (Indian Mangoes):
Irradiation requirements of imported Indian mangoes originally come from USDA-APHIS and 7 CFR § 305.9 regulations Irradiation phytosanitary treatment to disinfest imported commodities.
These regulations require:
a) irradiation treatment
b) pre-clearance supervision
c) phytosanitary certification
They do not require PPQ203 as the (mandatory) shipment certificate.
Parameters - Requirements
a) Minimum dose- 400 Gy (Grays)
b) Treatment type- Irradiation
c) Target pests- Fruit flies, mango seed weevil
d) Supervision- USDA-APHIS pre-clearance
6.9: Irradiation Treatment Certificate / Irradiation Certificate
(not a part of shipping docs, but internal docs in irradiation facility)
After irradiation treatment is completed, the treatment facility generates an official Irradiation Treatment Certificate.
This certificate records:
treatment facility identification
irradiation dose applied (typically 400 Gy)
treatment date and batch details
compliance with the required treatment protocol
Confirmation that the treatment meets export protocol requirements as per USDA-APHIS regulations.
USDA-APHIS inspectors supervise and verify the treatment process, but the certificate itself is normally issued by the treatment facility operator.
6.10: Key Irradiation Treatment parameters include:
APHIS Treatment Schedule: T105-a
Minimum absorbed dose: 400 Gy (Gray)
Target pests: Mango fruit fly and mango seed weevil
Supervision: USDA-APHIS inspectors under the Pre-Clearance Program
This treatment neutralizes quarantine pests without affecting fruit quality or shelf life.
STEP - (7): The APHIS Treatment Schedule Reference (T105-a):
The irradiation requirement used for mango exports to the United States is defined under the USDA-APHIS Treatment Manual.
For mangoes, the approved treatment schedule is:
APHIS Irradiation Treatment Schedule: T105-a
This treatment schedule T105-a requires:
Minimum absorbed irradiation dose: 400 Gy
Purpose: Neutralization of quarantine pests
Target pests:
(a) Mango fruit fly
(b) Mango seed weevil
The treatment is applied at APHIS-approved irradiation facilities (IFC) operating under the USDA-APHIS pre-clearance program.
A-1 OVERSEAS understands the importance of Irradiation Treatment as:
the APHIS phytosanitary treatment system
the required irradiation protocol
the quarantine pest control mechanism
We handle Badami and Banganapalli mango exports to USA & Canada with strict documentation, traceability, and packaging compliance.
STEP - (8): On-Site USDA-APHIS Inspection in India (The Actual "Pre-Clearance") by USDA-APHIS Officials in APEDA’s Irradiation Facility.
8.1: US Officials on the Ground:
During the Indian mango season, the US Government stations its own official USDA-APHIS inspectors directly inside the Indian irradiation facilities.
Their role includes:
8.2: Live Monitoring:
These American officials monitor the facility computers, treatment equipment, and irradiation dosage in real-time to ensure and verify that the radiation dosage is exact as per agreed norms between 2 countries, India and the US. These Officials monitor, inspect, and examine mangoes during any stage of the process, i.e., before or after HWT, before or after Irradiation, etc.
8.3: Official Clearance:
They conduct random physical inspections of the packed mangoes and officially "clear" the cargo while it is still sitting in the irradiation-treatment facility.
8.4: Final Processing (POST- IRRADIATION TREATMENT HANDLING) by USDA-APHIS Officials at APEDA PACKHOUSE
Export mango boxes, after coming out of irradiation chambers are inspected by USDA-APHIS Officer(s).
POST-IRRADIATION TREATMENT INSPECTION is the final checking, examination, inspection stage of mangoes.
These officers randomly check few boxes from the entire consignment. If after satisfied examination, inspection they found no issue then they allow the export of that entire subject consignment with giving approval for the necessary documents.
Once the inspectors are satisfied that all requirements are met, the cargo is officially cleared for entry into the United States while still in India. Then PPQ FORM 203 is issued and Mango Boxes are sealed with Tamper Proof Radular Label / Radura Symbol.
STEP - (9): Physical Chain of Custody (Cargo Lockdown), Tamper-Proofing and Radura Label / Radura Symbol Statement
A flawless PPQ Form 203 is immediately voided if the physical cargo is compromised during the 14,000 km air transit.
9.1: USDA-Mandated Sealing - Cargo Lockdown:
Immediately after treatment verification, the approved export mango cartons or pallets are locked down with specialized, US-mandated tamper-proof seals under official supervision to guarantee the chain of custody is not broken during transit.
9.2: The Border Risk:
If CBP officers find a broken or missing seal upon arrival in New York or Chicago, the pre-clearance status is revoked. This results in severe consequences, including mandatory quarantine holds, forced re-inspections, or total rejection of entry.
9.3: Retail Consumer Compliance - Radura Label / Radura Symbol Statement:
· For retail-bound shipments, cartons are printed with the international "Radura Symbol”, ensuring importers remain fully compliant with US FDA consumer labeling laws for irradiated foods.
· For consumer-packaged irradiated foods, the internationally recognized "Radura Symbol” is used to indicate irradiation treatment in compliance with US food labeling regulations.
· The Radura symbol is required for irradiated foods sold directly to consumers. Shipping cartons used for wholesale distribution may not always display it.
