Lychee

Exporting lychee from Vietnam follows seven sequential stages: harvest planning, post-harvest preparation, sorting and packing, documentation, customs clearance, cold-chain transport, and delivery to the destination port. Each stage carries strict timing constraints, particularly the critical window of getting fresh lychee into the packing house within 12 hours of harvest to lock in peak freshness and maximize shelf life. For businesses entering international markets for the first time, understanding this end-to-end process is the essential starting point.

Meeting the requirements to export lychee legally and successfully means satisfying three layers of compliance: a complete documentation package covering the Phytosanitary Certificate, Certificate of Origin, Commercial Invoice, and more; phytosanitary and food safety regulations specific to each import market; and pre-registration with the relevant destination-country authorities before shipping the first consignment. These requirements are not uniform. The United States, the European Union, Japan, and the Middle East each maintain distinct regulatory frameworks, and a shipment cleared for one market may not automatically meet the standards of another.

Beyond procedures and regulatory requirements, exported lychee must conform to internationally recognized quality and safety standards including GlobalGAP, ISO, FDA, and Codex Alimentarius guidelines. These standards govern everything from maximum residue levels for pesticides to packaging specifications, labeling content, and cold chain integrity from packing house to end consumer. For exporters aiming to build long-term trading relationships with supermarkets and distributors worldwide, achieving and maintaining these certifications is the foundation of a credible, competitive export operation.

What Is the Step-by-Step Process for Exporting Lychee?

Exporting lychee involves seven sequential stages: harvest planning, timely harvesting, post-harvest handling and sorting, packing, documentation preparation, customs clearance, and refrigerated transport to the destination port. Each stage is time-sensitive, and delays at any point can compromise product quality and market access. The sections below break down each stage in full, from the farm gate to the final port of delivery.

How Should Lychee Be Harvested and Prepared Before Export?

Lychee must be harvested at precise maturity, with sugar content reaching 18 to 22 percent for U Hong and 20 to 22 percent for Thieu, before any post-harvest handling begins. Harvesting at the wrong stage directly shortens shelf life and reduces the product’s appeal to international buyers. The following steps outline the complete post-harvest preparation process for export-grade lychee.

• Visual inspection at the farm: Damaged, cracked, or diseased fruit is removed immediately to prevent cross-contamination during transport to the packing house.
• Rapid transfer to the packing facility: Lychee must reach the packing house within 12 hours of harvest. Facilities located directly within growing regions, such as Gobeimex’s Tien Giang packing house in the heart of Vietnam’s fruit-growing belt, are positioned to meet this window consistently.
• Grading and sizing: Fruit is sorted by size measured in pieces per kilogram. U Hong lychee falls within the 20 to 26 pcs/kg range, while Thieu lychee grades at 32 to 38 pcs/kg. Uniform sizing is a key quality requirement for supermarket buyers across Europe, North America, and Asia.
• Pre-cooling: After sorting, lychee moves into pre-cooling units to rapidly bring the core temperature down to 2 to 4 degrees Celsius before packing, preventing thermal stress and slowing enzymatic browning.
• Final quality check: A quality control team inspects the sorted fruit against the buyer’s specifications before packing begins.

The proximity of the packing house to the growing area is not a logistical convenience alone. It is a structural advantage that directly determines whether the product arrives at the destination in peak condition. Gobeimex’s Tien Giang facility, positioned within the primary lychee-growing region, allows fruit to move from orchard to cold storage in the shortest possible time, preserving natural sugar content, skin color, and aroma before shipment.

What Are the Recommended Shipping Methods for Exporting Lychee?

There are two primary shipping methods for exporting lychee: air freight and sea freight, and the correct choice depends on the lychee variety, the target market’s distance from Vietnam, and the buyer’s lead time requirements. The choice between methods directly affects logistics cost, viable market reach, and the risk of quality failure during transit. The table below summarizes which shipping method applies to each variety based on shelf life data.

The table below compares U Hong and Thieu lychee across shipping options and destination market suitability. Exporters can use it to select the correct logistics method for each variety and target market.

This table shows that U Hong lychee’s 40-day shelf life makes it commercially viable for sea freight to distant markets, while Thieu lychee’s 7-day shelf life restricts it exclusively to air freight and short transit routes. The following practical considerations should also inform the shipping method decision.

• Air freight guarantees the fastest transit, typically 1 to 3 days to most destinations, making it the only viable option for Thieu lychee and the preferred method for time-sensitive premium orders of U Hong.
• Sea freight reduces per-kilogram logistics costs for U Hong shipments to Europe, Canada, the UAE, and other long-haul destinations. Maintaining an unbroken cold chain throughout the entire sea journey is non-negotiable. Any temperature deviation during the voyage can shorten the effective shelf life and cause skin browning or flavor degradation before the product clears customs at the destination port.
• Market-driven decisions: Buyers in Japan, the Maldives, and premium retail channels in the Gulf often specify air freight regardless of variety due to their preference for the freshest possible product. Exporters supplying these segments should factor in the higher logistics cost when building FOB and CIF pricing structures.

For most exporting businesses, a dual-variety strategy that pairs U Hong for sea freight routes with Thieu for air freight to premium nearby markets allows maximum revenue optimization across the full May-to-July harvest season.

What Are the Key Requirements for Exporting Lychee?

Exporting lychee legally requires meeting three categories of mandatory requirements: a complete documentation package, compliance with phytosanitary and food safety regulations, and adherence to the specific import rules of each destination market. These requirements are market-dependent, and each importing country enforces its own distinct set of conditions. The sections below cover each requirement category in detail, with specific guidance for the most important destination markets.

What Documents Are Required to Export Lychee?

A complete lychee export documentation package includes six core documents: a Phytosanitary Certificate, a Certificate of Origin, a Commercial Invoice, a Packing List, a Bill of Lading or Airway Bill, and a Health Certificate. Each document serves a distinct function and must be prepared accurately and on time to avoid shipment delays at the port of export or the port of entry. The table below outlines each document, its issuing authority in Vietnam, and its primary function.

The table below lists all mandatory export documents for lychee shipments from Vietnam. Reviewing this list against each shipment ensures that no document is missing before handover to the freight forwarder.

Beyond the documents themselves, the following practical considerations directly affect whether a shipment clears customs without delay.

• Lead time for phytosanitary inspection: The Phytosanitary Certificate requires a physical inspection of the shipment by plant protection officers. Schedule this inspection at least 2 to 3 working days before vessel or flight departure to allow sufficient time for inspection, issuance, and document delivery to the freight forwarder.
• Certificate of Origin form selection: The applicable C/O form varies by destination market. Form E applies for ASEAN-China FTA shipments, Form AJ for Japan, Form EUR.1 for the EU, and Form A for GSP-eligible markets. Selecting the incorrect form will result in rejection of preferential tariff claims at the destination.
• Common documentation errors: Discrepancies between the weight on the Packing List and the Commercial Invoice, differences in product description between the Phytosanitary Certificate and the Bill of Lading, and incorrect HS codes are among the most frequent causes of customs delays. A thorough pre-shipment document audit is strongly recommended before handing any paperwork to the freight forwarder.

According to export compliance guidelines issued by Vietnam’s Ministry of Agriculture and Rural Development (MARD, 2023), all phytosanitary certificates for fresh lychee exports must be issued within 24 hours of the scheduled departure to retain their validity at most destination ports of entry.

What Phytosanitary and Regulatory Requirements Apply to Lychee Imports by Market?

Each major import market enforces its own phytosanitary and regulatory requirements for fresh lychee, covering pest control, maximum residue limits, and mandatory pre-entry treatments, and exporters must research and comply with the specific rules of each destination before preparing the first shipment. Requirements vary substantially between markets, and a compliant shipment for one country may be rejected by another. The breakdown below covers the key requirements for the most important destination markets.

United States, US FDA and USDA APHIS

Lychee exported from Vietnam to the United States must undergo irradiation treatment in a USDA-approved facility before export. This is a mandatory phytosanitary measure designed to neutralize fruit flies and other quarantine pests. The exporting company must also be registered with the US FDA under the Prior Notice and Food Facility Registration requirements of the Bioterrorism Act. Pesticide residue levels must comply with US EPA maximum residue limit tolerances, which in some cases are stricter than Codex Alimentarius international standards.

European Union

The EU enforces phytosanitary regulations under Commission Regulation (EC) No. 669/2009 and related directives. Fresh lychee from Vietnam is subject to import controls at designated border inspection posts. Pesticide maximum residue limits are governed by Regulation (EC) No. 396/2005, and EU standards are among the most stringent globally, particularly for certain fungicides and insecticides. The EU also requires that all food businesses in the exporting country be registered and that MARD formally guarantees the food safety of the exported product.

Japan

Japan enforces lychee import requirements under the Plant Protection Law and the Food Sanitation Law. Japan may require vapor heat treatment as a condition of entry to control Oriental fruit fly and other listed pests. Maximum residue limit requirements under Japan’s Positive List System are highly specific and cover hundreds of active pesticide substances. Exporters are strongly advised to obtain a full pesticide residue screening report from a Japanese-accredited laboratory before shipping to this market.

Middle East, UAE, Kuwait, Saudi Arabia

Import requirements in Gulf Cooperation Council countries are governed by the Gulf Standardization Organization and individual national food authorities. Health certificates, Certificates of Origin, and phytosanitary certificates are standard requirements. Pesticide residue testing must conform to Codex Alimentarius maximum residue limit standards or the importing country’s national standards, whichever are stricter.

A key recommendation for all markets: establish formal communication with the import regulatory authority or the in-country importer well before the first shipment. Regulatory frameworks change, and a pre-clearance consultation reduces the risk of rejection at the border.

What Quality and Safety Standards Must Exported Lychee Meet?

Exported lychee must meet four internationally recognized quality and food safety standard frameworks: GlobalGAP, ISO quality management systems, FDA food safety requirements, and Codex Alimentarius guidelines on maximum residue limits and fresh produce handling. Compliance with these standards is both a market access requirement and a commercial differentiator that builds buyer confidence and supports premium pricing. The sections below detail the specific requirements that apply to packaging, labeling, cold chain integrity, and storage throughout the export journey.

What Packaging and Labeling Standards Apply to Exported Lychee?

Exported lychee must be packed in standardized inner units of 500 grams or 1 kilogram, placed inside outer cartons available in 1, 2, 5, 12, or 16 kilogram configurations, each suited to different distribution channels and retail environments. The correct combination of inner and outer packaging protects the fruit during transit and communicates professionalism to international buyers. The table below shows how each outer box configuration is best matched to a specific distribution channel.

The table below maps each carton size to the distribution channel it is best suited for. Selecting the right configuration for each buyer type reduces packaging waste and improves shelf presentation.

Beyond physical packing specifications, every carton of exported lychee must carry a label that complies with the labeling regulations of the destination market. The following elements are mandatory on every export label.

• Product name: “Fresh Lychee” or the local-language equivalent as required by the importing country.
• Country of origin: “Product of Vietnam” clearly printed on both the inner and outer packaging.
• Net weight: Stated in the unit system of the destination market, kilograms for the EU, UK, Middle East, and Asia, and pounds for the US and Canada where applicable.
• Packing date and best-before date: Critical for cold chain verification and regulatory compliance at customs.
• Storage instructions: “Keep refrigerated at 2 to 4 degrees Celsius” printed in both English and the local language of the destination market where required.
• Traceability code: A barcode or QR code linking the package to the farm of origin, harvest date, packing house batch number, and quality control record. This is increasingly mandatory for EU supermarket listings and is standard practice for GlobalGAP-certified supply chains.

Exporters supplying the European market should also note that the EU’s Green Deal and Farm to Fork strategy are driving growing buyer preference for recyclable or compostable outer packaging materials. Transitioning from conventional corrugated cartons treated with non-recyclable wax coatings to fully recyclable corrugated materials is a proactive step that strengthens long-term competitiveness in European retail channels.

What Cold Chain and Storage Standards Must Be Maintained for Lychee Export?

An unbroken cold chain maintained at 2 to 4 degrees Celsius from the packing house through to the end consumer is the single most critical factor determining whether exported lychee arrives in marketable condition. Any interruption in temperature control, even briefly, accelerates browning, reduces sugar content, and shortens effective shelf life. The following operational standards apply at each stage of the cold chain.

At the packing house: Pre-cooling equipment must bring the core fruit temperature down to 2 to 4 degrees Celsius before packing begins. Packing must be carried out in a temperature-controlled environment to prevent the product from warming up during the packing operation itself.

During transport from packing house to port: Refrigerated container trucks must maintain 2 to 4 degrees Celsius continuously. Gobeimex operates its own fleet of refrigerated container trailers for this stage, eliminating the risk of temperature breaks caused by third-party logistics handoffs. Every reefer unit should be pre-cooled to the target temperature before loading, and temperature data loggers should be fitted to record the thermal history of the cargo throughout the journey.

During sea or air transit: For sea freight, reefer containers must be set and verified at 2 to 4 degrees Celsius before stuffing. The carrier is responsible for maintaining this temperature for the duration of the voyage. Exporters should request a temperature log download from the reefer controller at the destination port as part of their quality assurance protocol. For air freight, cool dolly transfers between the packing facility and the aircraft cargo hold are essential to maintain cold chain integrity at the airport.

The table below shows the impact of cold chain integrity on the shelf life of both primary export varieties. It quantifies the commercial cost of any temperature breach during transit.

This table highlights why cold chain management is proportionally more critical for Thieu lychee, which has almost no buffer for temperature deviations during transit. The following certifications are relevant to cold chain logistics compliance in fresh produce export.

• ISO 22000: Food safety management systems standard, applicable to packing houses and logistics operators.
• HACCP: Required by many markets as part of the food safety management system for fresh produce.
• GDP, Good Distribution Practice: International guidelines for the proper distribution of temperature-sensitive products.
• GlobalGAP add-on modules: Include requirements for post-harvest handling and cold chain management as part of the full farm-to-retailer chain of custody.

Companies like Gobeimex, which hold GlobalGAP, ISO, FDA, and Sedex certifications and operate their own controlled logistics infrastructure, offer buyers an end-to-end cold chain guarantee that reduces the risk of quality failures at the destination.

Which Lychee Variety Is Better Suited for Export, U Hong or Thieu?

U Hong lychee is the stronger choice for long-haul export to Europe, Canada, and the Middle East because of its 40-day shelf life and compatibility with both air and sea freight, while Thieu lychee is better suited to premium short-haul markets, particularly Japan and regional Asia, where its distinctive flavor profile commands a higher price premium despite its 7-day shelf life limitation. For exporters building a commercial export program, the choice between varieties is not necessarily an either-or decision. The two sections below compare both varieties in detail and address the question of special treatment protocols required by specific markets.

How Do U Hong and Thieu Lychee Compare Across Key Export Criteria?

U Hong leads on logistics flexibility and market reach; Thieu leads on flavor intensity and premium positioning in markets willing to pay for it. Understanding this distinction allows exporters to design a variety allocation strategy that maximizes both volume and margin across the May-to-July harvest window. The table below presents a direct comparison across the criteria that matter most to export businesses.

The table below compares U Hong and Thieu lychee across eight export criteria. Exporters can use it to match each variety to the most suitable destination market and shipping method.

U Hong’s 40-day shelf life is its defining competitive advantage for export, allowing it to reach distant markets via sea freight at a fraction of the cost of air shipment, while still arriving fresh and commercially viable. Thieu’s smaller berry size and higher natural sugar concentration appeal to premium buyer segments that prize flavor complexity, but its 7-day shelf life makes it an operationally demanding product requiring near-perfect coordination from harvest to in-store display.

Do Certain Export Markets Require Special Treatment Protocols for Lychee?

Yes, specific export markets require mandatory treatment protocols for lychee before entry is permitted: the United States requires irradiation treatment certified by a USDA APHIS-approved facility, while Japan and South Korea may require vapor heat treatment to eliminate quarantine pests including Oriental fruit fly. Exporters must integrate these treatment steps into their production schedule before targeting these markets, as no shipment will be cleared without documented proof of approved treatment. The following guidance applies to planning these treatments effectively.

• US market: Contact a USDA APHIS-approved irradiation facility in Vietnam early in the season planning cycle. Treatment slots fill quickly during the peak May-to-June harvest window.
• Japan and South Korea: Confirm whether vapor heat treatment is required for the current season through official channels with the importing country’s plant quarantine authority before committing to a shipment.
• Scheduling buffer: Build at least 3 to 5 additional days into the production and logistics timeline to accommodate treatment, re-inspection, and documentation issuance without missing the vessel or flight booking.

According to USDA APHIS import requirements (2023), irradiation treatment for fresh lychee must be performed at a minimum absorbed dose of 400 Gray to ensure elimination of all quarantine pest life stages before entry into the United States.
