Vietnamese rambutan has a major opportunity to expand its market share in the U.S. now that tropical fruit was added to the list exempt from reciprocal tariffs starting November 2025, while demand for imported tropical fruit in this market continues to grow steadily each year.
However, unlike more accommodating markets, the rambutan export procedure to the U.S. requires businesses to simultaneously meet Vietnamese regulations (phytosanitary inspection, growing area codes, customs) as well as a series of strict requirements from the USDA-APHIS, particularly mandatory irradiation and registration of growing areas and packing facilities.
The article below summarizes the entire process, standards, HS codes, costs, and common risks involved in the rambutan export procedure to the U.S., helping businesses proactively prepare documentation and avoid mistakes that cause customs delays or shipment returns.
1. Export Potential for Rambutan in the U.S. and European Markets
According to data from the U.S. International Trade Commission (USITC), during the first 10 months of 2025, Vietnam accounted for approximately 1.49% of total U.S. imports of vegetables, flowers, fruit, and processed products – a still-modest share but one that indicates substantial room for growth if businesses meet the right quality standards and supply capacity.
Notably, starting November 13, 2025, the U.S. removed a series of agricultural product groups – including tropical fruits, coffee, tea, cocoa, and spices from the list subject to additional reciprocal tariffs under Executive Order 14257. This is a direct positive signal for the rambutan industry, helping to reduce cost pressure and increase competitiveness against Thai and Malaysian rambutan in the U.S. market.
In terms of market share structure, most of Vietnam’s rambutan export volume from early 2025 to mid-2026 has continued to concentrate on the Chinese market via both informal (small-scale border) and formal trade channels, while the U.S. and Europe hold a smaller share but are growing quickly thanks to the expanding GlobalGAP and VietGAP-certified growing areas in Ben Tre, Vinh Long, and Dong Nai.
2. What Standards Must Rambutan Meet for Export to the U.S.?
Growing Area Standards
A prerequisite for Vietnamese rambutan to be permitted for import into the U.S. is that the growing area must be registered with the Plant Protection Department (now part of the Department of Crop Production and Plant Protection) and monitored by the U.S. Animal and Plant Health Inspection Service (APHIS) under the “systems approach” specified in 7 CFR 319.56.
Under the APHIS decision published in 2011 permitting the import of fresh rambutan from Vietnam and Malaysia, each shipment must be sampled, inspected, and confirmed free of the fungus Oidium nephelii prior to export.
Notable rambutan growing areas in Vietnam that currently hold growing area codes for export include: Cho Lach, Chau Thanh (Ben Tre); Long Ho (Vinh Long); Long Khanh, Xuan Loc (Dong Nai). These are also the areas that grow Java rambutan and “longan-type” rambutan (chôm chôm nhãn) in large volumes and are already accustomed to cultivation practices meeting export standards.
The Growing Area Code (GAC), issued by the Department of Crop Production and Plant Protection, is a mandatory requirement for tracing the origin of shipments during export phytosanitary procedures. Businesses need to select a source growing area with a valid, currently active code, to avoid rejection of the phytosanitary certificate due to an unregistered area or one whose monitoring status has expired.
Size and Color Standards (per CODEX Alimentarius)
| By Individual Fruit | By Cluster | ||
|---|---|---|---|
| Size Grade | Weight per fruit (grams) | Number of fruits per kg | Number of fruits per kg |
| 1 | > 43 | < 23 | < 29 |
| 2 | 38 – 43 | 23 – 26 | 29 – 34 |
| 3 | 33 – 37 | 27 – 30 | 25 – 40 |
| 4 | 29 – 32 | 31 – 34 | 41 – 45 |
| 5 | 25 – 28 | 35 – 40 | |
| 6 | 18 – 24 | 40 – 50 | |
Export rambutan quality is assessed against CODEX STAN 197-1995 (CODEX Alimentarius)—the international standard applicable to fresh rambutan in commercial trade. Under this standard, rambutan is classified into 3 quality grades and sized either by individual fruit weight or by cluster.
| Quality Grade | Fruit Characteristics | Allowed Tolerance |
|---|---|---|
| Extra Class | Highest quality, characteristic shape, uniform color, no defects, fresh-looking spinterns | Up to 5% of fruits not meeting Extra Class but still meeting Class I |
| Class I | Good quality, minor shape defects allowed, color does not affect storage | Up to 10% of fruits not meeting Class I but still meeting Class II |
| Class II | Does not meet a higher grade but satisfies minimum requirements, spinterns may be slightly darkened | Up to 10% of fruits not meeting the minimum requirements |
Regarding sizing, CODEX Alimentarius specifies the weight of individual fruit or clusters according to size codes; businesses need to agree with the U.S. importer on the specific fruit size (typically 20-33g/fruit for Java rambutan) right from the harvesting stage to avoid the need for re-sorting, which causes loss and delays packing progress.
Packaging Specifications and Standards
Rambutan exported to the U.S. is typically packed in clusters or loose fruit in ventilated carton boxes, with common weights of 1kg, 2kg, or 5kg per box, lined with paper or perforated PE bags to allow moisture release and limit mold growth during long transport.
Packaging must clearly print: product name in English (Rambutan), country of origin (Product of Vietnam), growing area code, packing facility code, packing date, and the mandatory phrase “Treated by Irradiation” along with the Radura symbol as required by the FDA for irradiated food products. Pallets must undergo wood quarantine treatment per the ISPM 15 standard if wooden pallets are used.
Technical and Preservation Requirements
Insect and Fungal Disease Control Standards
Each shipment must be inspected to confirm the absence of quarantine pests, and in particular must demonstrate freedom from the fungus Oidium nephelii per the specific requirement for rambutan originating from Vietnam.
Irradiation Process
This is a mandatory requirement with no exceptions. The entire rambutan shipment must be irradiated at an APHIS-approved facility (Vietnam currently has approved irradiation facilities located in the southern region.
The Toan Phat Irradiation Facility was recently approved by APHIS to add X-ray processing technology alongside its existing Cobalt-60 gamma irradiation technology, increasing processing capacity during peak season), with a minimum absorbed dose of 400 Gy per the requirements of 7 CFR Part 305.
The shipment must be directly supervised during the irradiation process and sealed by an APHIS officer stationed in Vietnam (preclearance) before export.
Pesticide Residue Levels
Alongside irradiation, rambutan must still meet the maximum residue limits (MRL) set by the FDA. Businesses should require the growing area to strictly comply with pre-harvest pesticide withdrawal periods and maintain records of pesticide use to support traceability when needed.
3. HS Code and Export Tax for rambutan export procedure to the U.S.
Correctly determining the HS code directly affects the tax rate, specialized management policies, and customs clearance speed. Fresh rambutan falls under Chapter 08 – “Edible fruit and nuts,” heading 08.10 – “Other fresh fruit.” For processed or preserved rambutan (canned, syrup-preserved), the HS code shifts to heading 20.08.
| Product Type | HS Code (Vietnam) | VN Export Tax | U.S. Import Tax Notes |
|---|---|---|---|
| Fresh rambutan | 0810.90.90 | 0% | MFN tariff for fresh fruit under heading 0810.90 is generally 0%; as of November 13, 2025, tropical fruit was excluded from the 20% additional reciprocal tariff on Vietnamese goods |
| Frozen rambutan | 0811.90.xx | 0% | Requires re-verification based on actual catalogue/classification |
| Processed, canned rambutan | 2008.99.10 | 0% | U.S. import tax under the processed fruit and vegetable category, requires detailed lookup on the HTS by ingredient composition |
Practical note: The tax rates listed above are for reference purposes only at the time this article was compiled. U.S. reciprocal tariff policy toward Vietnamese goods is still under continuous negotiation and adjustment (from an initial rate of 46% in April 2025, reduced to 20% starting August 2025, with several agricultural product groups including tropical fruit excluded from the additional reciprocal tariff starting November 2025). Businesses must look up the exact HS code on the U.S. HTS System (hts.usitc.gov) and the Vietnam General Department of Customs website before each shipment, and should work with an experienced logistics provider on the U.S. route to stay updated on current tax rates, to avoid misclassification that leads to retroactive tax collection or delayed clearance.
Real export tax calculation: For fresh rambutan under HS code 0810.90.90, Vietnam’s export tax is 0%, so businesses incur no export tax cost. Tax costs mainly arise on the U.S. import side (borne by the importer per the agreed Incoterms), but Vietnamese businesses still need to understand this clearly in order to negotiate an appropriate selling price and delivery terms, avoiding disputes if U.S. customs applies a different tax rate than what was originally agreed between the two parties.
4. Documentation Required for the Rambutan Export Procedure to the U.S.
| Document | When to Prepare | Important Notes |
|---|---|---|
| Sales Contract | Before harvest and packing | Clearly state Incoterms, packaging specifications, and quality grade per CODEX |
| Commercial Invoice | After packing, before customs declaration | Value must match the contract and bill of lading |
| Packing List | Same time as the Invoice | Record detailed package count, net/gross weight for each packaging type |
| Phytosanitary Certificate | Before the shipment reaches the port, after irradiation | Must include a supplementary declaration confirming irradiation and freedom from Oidium nephelii |
| Irradiation Certificate | Immediately after irradiation is completed | Must clearly state the minimum absorbed dose of 400 Gy, with confirmation from the APHIS preclearance officer |
| Certificate of Origin (C/O) | After the export customs declaration | Not mandatory for tariff preference, but recommended to prove origin if requested by U.S. customs |
| Ocean/Air Bill of Lading (B/L, AWB) | After container/cargo handover to the shipping line or airline | Carefully verify consignee information and destination port to avoid delays with AMS/ISF filing |
| Export Customs Declaration (VNACCS) | Before customs clearance | Declare the correct HS code and customs value using the transaction value method |
5. Rambutan Export Procedure to the U.S.
Step 1: Register the Growing Area and Packing Facility
Businesses work with the local Department of Crop Production and Plant Protection to register the growing area code and packing facility code as required by the U.S. market. Growing areas must be periodically monitored to maintain code validity.
Step 2: Sign the Contract and Plan Harvest and Packing
Agree with the U.S. importer on the quality grade per CODEX, fruit size, packaging specifications, and delivery timing to proactively schedule the harvest, avoiding overripe rambutan that would affect quality during long-distance transport.
Step 3: Inspection, Sampling, and Obtaining the Phytosanitary Certificate
Register for phytosanitary inspection with the relevant authority; inspection officers take representative samples to check for pests, particularly confirming freedom from the fungus Oidium nephelii, before proceeding to the irradiation step.
Step 4: Irradiation at an APHIS-Approved Facility
The shipment is transported to the irradiation facility and treated with a minimum absorbed dose of 400 Gy under the supervision of an APHIS preclearance officer in Vietnam. Once completed, the irradiation facility issues an irradiation certificate along with a shipment seal.
Step 5: Finalize Documentation and Declare Export Customs
The business or forwarder prepares the Invoice, Packing List, and contract, then files the electronic customs declaration on the VNACCS system, attaching the phytosanitary certificate and irradiation certificate.
Step 6: Booking Vessel/Flight and Domestic Transport to Port/Airport
Arrange reefer containers or air cargo pallets, maintaining a stable storage temperature for the rambutan (typically 8-12°C) throughout the journey to minimize loss, skin cracking, and darkening of the spinterns.
Step 7: Export Customs Clearance and Handover to the Carrier
After the declaration is cleared (green, yellow, or red channel depending on the classification result), the shipment is delivered to the yard or handed over to the shipping line/airline for export.
Step 8: Import Customs Clearance in the U.S.
The importer or U.S. agent coordinates with CBP (U.S. Customs and Border Protection) and the FDA to inspect documentation, verify the irradiation certificate and phytosanitary certificate, before clearance and distribution to the market.
6. Routes and Transport Methods for Rambutan from Vietnam to the U.S.
Given that rambutan is a fresh fruit prone to spoilage, moisture loss, and skin discoloration, businesses typically choose between two main methods:
Air freight: Preferred for small, high-value shipments that need to be delivered quickly within 1-3 days, ensuring maximum freshness. The drawback is significantly higher cost compared to sea freight, suitable for trial market orders or to meet demand around holidays and Tet within the Vietnamese community in the U.S.
Sea freight via reefer container: Suitable for large shipments departing from Cat Lai (Ho Chi Minh City), Hai Phong, and Da Nang ports to major U.S. ports such as Los Angeles, Long Beach, Oakland, Houston, New York/New Jersey, and Savannah. Transit time is typically 18-30 days depending on the destination port, requiring preservation technology such as MAP (Modified Atmosphere Packaging) bags and ethylene absorbers to extend shelf life in the container.
Since rambutan has a much shorter shelf life than many other fruits (typically only 7-12 days under ideal conditions), businesses need to carefully weigh cost against transit time, while working closely with logistics providers to book reefer container space early, to avoid space shortages during peak harvest season.
7. Timeline and Costs of the Rambutan Export Procedure to the U.S.
The entire process, from harvest to arrival at a U.S. port, typically takes 20-35 days by sea, much shorter by air. Below is a detailed timeline for each stage:
| Stage | Estimated Time | Notes |
|---|---|---|
| Harvesting, sorting, packing | 1 day | Harvest in the early morning; pre-cool immediately after harvest to lower the fruit’s core temperature |
| Registration and phytosanitary sampling | 0.5 – 1 day | Inspection for freedom from Oidium nephelii, issuance of the Phytosanitary Certificate |
| Transport to the facility and irradiation | 1 – 2 days | May take longer during peak season if the irradiation facility is over capacity |
| Export customs declaration (VNACCS) | 0.5 – 1 day | Faster if the declaration is routed to the green channel |
| Air transport to the U.S. | 1 – 3 days | Applies to small shipments requiring urgent delivery and maximum freshness |
| Sea transport (reefer container) | 18 – 30 days | Depends on the destination port: Los Angeles, Long Beach are faster; New York, Savannah take longer |
| U.S. import clearance (CBP/FDA) | 1 – 3 days | May take longer if routed for physical inspection or if the irradiation certificate is missing |
| Total time (sea freight) | Approximately 22 – 38 days | From harvest to customs clearance, ready for distribution in the U.S. |
| Total time (air freight) | Approximately 5 – 8 days | Suitable for small, high-value shipments requiring maximum freshness |
Regarding costs, businesses need to budget for various line items, with irradiation and international freight typically accounting for the largest share. The table below summarizes reference costs for a rambutan export shipment to the U.S.:
| Cost Item | Reference Rate | Notes |
|---|---|---|
| Phytosanitary inspection, Certificate issuance | 500,000 – 1,000,000 VND/shipment | Fixed fee per shipment, not based on weight |
| Irradiation at an APHIS-approved facility | Approx. $0.8 – $1/kg (~20,000 – 25,000 VND/kg) | This is the largest cost item, specific to the U.S. route due to the requirement of APHIS preclearance officer supervision; price may vary by facility and shipment volume |
| Export customs declaration fee | 800,000 – 1,500,000 VND/declaration | Depends on the customs brokerage service provider |
| AMS/ISF filing fee for the U.S. | $30 – $50/shipment | Mandatory for sea shipments to the U.S., performed by an NVOCC with FMC bond |
| Cold storage fee (if delays occur waiting for vessel/irradiation) | 150,000 – 300,000 VND/ton/day | Best avoided by booking vessel space and irradiation schedule early |
Practical note: The costs and timeframes listed above are for reference only, compiled from data published by irradiation facilities, shipping lines, and fruit exporting businesses at various points in time; irradiation costs for the U.S. route have in practice been reported by some rambutan exporting businesses as significantly higher than for other markets, due to the specific supervision requirement of APHIS preclearance officers. International freight rates, irradiation fees, and surcharges at U.S. ports fluctuate continuously based on season, fuel prices, and reefer container supply-demand conditions. Businesses should request detailed, up-to-date quotes for each specific shipment from their logistics provider and irradiation facility before finalizing their business plan, rather than relying entirely on historical reference figures.
8. Risk Considerations in the Rambutan Export Procedure to the U.S.
| Risk | Symptom | Prevention |
|---|---|---|
| Growing area does not meet requirements | Phytosanitary certificate rejected, unable to export on schedule | Verify growing area code validity before signing the contract; only purchase from areas registered with APHIS |
| Missing irradiation or insufficient dose | Shipment held, destroyed, or returned upon arrival at a U.S. port | Only work with APHIS-approved irradiation facilities; keep full irradiation certification records |
| Incorrect HS code declaration | Retroactive tax collection, delayed clearance, requires declaration correction | Carefully verify the HS code with a customs broker/forwarder experienced in fresh agricultural products |
| Cold chain break during transport | Rambutan skin darkens, moisture loss, spoilage upon arrival at port | Use certified reefer containers, monitor temperature throughout, combine with MAP packaging/ethylene absorbers |
| Pesticide residue exceeds limits | FDA holds the shipment for inspection, increased risk of Import Alert listing | Comply with pesticide withdrawal periods, maintain cultivation records, conduct periodic residue testing before harvest |
| Reefer container shortage during peak season | Shipment must be held in cold storage awaiting vessel space, incurring costs and reducing quality | Book early with a logistics provider that has partnerships with multiple shipping lines; plan ahead for the season |
9. FAQ – Frequently Asked Questions About the Rambutan Export Procedure to the U.S.
Question 1: Is fresh rambutan exported to the U.S. required to be irradiated?
Yes. Per APHIS regulations, all fresh rambutan originating from Vietnam must undergo irradiation with a minimum absorbed dose of 400 Gy at an approved facility before export—there is no accepted alternative for this product.
Question 2: What is the current U.S. import tax on Vietnamese fresh rambutan?
Fresh rambutan, as a tropical fruit, generally carries a 0% MFN tariff under the U.S. HTS Schedule. As of November 2025, tropical fruit was also excluded from the additional reciprocal tariff applied specifically to Vietnamese goods. However, businesses should still verify the exact HS code and current tax rate at the time of export, as policy may change.
Question 3: How long can rambutan be preserved during sea transport to the U.S.?
Under optimal cold storage conditions (approximately 8-12°C) combined with MAP packaging and ethylene absorbers, rambutan can maintain quality for about 10-14 days. Businesses should therefore carefully weigh sea versus air transport depending on the destination port and actual transit time.
Question 4: Can rambutan be exported to the U.S. from a growing area without a code?
No. The growing area must be registered and monitored by the Department of Crop Production and Plant Protection as required by APHIS. Businesses need to proactively work with the local department to register the growing area code and packing facility code before planning to export.
Question 5: Besides irradiation, what else must rambutan be inspected for before export?
The shipment must also be inspected and confirmed free of the fungus Oidium nephelii, meet the maximum pesticide residue limits set by the FDA, and have a complete phytosanitary certificate issued by the Vietnamese quarantine authority, along with the supplementary declaration required specifically for the U.S. market.
