Import of Southeast Asian Tropical Fruits: Pitfalls and Solutions in Customs Declaration and Taxation

In 2026,the value of tropical fruits imported by Shanghai from Southeast Asia increased by 32% year-on-year.However,many fruit trading enterprises have stumbled in the customs declaration and taxation links —— some had their goods detained by customs due to incomplete documents,incurring storage fees of 2,000 yuan per day; some overpaid tariffs by using incorrect HS codes,spending over 30,000 yuan more for 10 containers of durians; others had their entire batch of mangosteens returned due to missed quarantine requirements,suffering a loss of nearly 500,000 yuan.These problems seem scattered,but they are hidden in every node of the entire import process.Zhongshen’s import agency service is the key to helping enterprises accurately hit the "safety points".

1.Document Pre-Check: The "First Barrier" Before Importation

The compliance requirements for importing Southeast Asian tropical fruits are more detailed than ordinary goods.Incomplete or incorrect documents will directly lead to failure in customs declaration.The team led by Manager Zhou from Zhongshen will intervene in pre-check 10 days before the goods are shipped,focusing on verifying the following 3 types of documents:

• Phytosanitary Certificate: Issued by the official quarantine department of the exporting country,indicating the fruit variety,origin,packaging method and transportation temperature.A new note item "Qualified Radioactivity Test" was added in 2026;
• Certificate of Origin (FORME): The key to enjoying preferential tax rates under the China-ASEAN Free Trade Area.It must be completely consistent with the value and variety stated in the contract and invoice,otherwise tariff deductions cannot be made;
• Importer filing materials: Provide the registration certificate of import and export cargo owners filed with Shanghai Customs,and the quarantine approval document for fruit import (valid for 6 months).

Last year,Mr.Dong,who engaged in fruit trade,imported fresh durians from Thailand.The quarantine certificate sent by the exporting country’s agent missed the official seal.He spent 7 days contacting for reissuance on his own,which resulted in the goods being unable to be declared upon arrival,incurring a 14,000 yuan demurrage fee.This year,Mr.Dong entrusted Zhongshen as his agent.Manager Zhou found the problem during the pre-check 12 days in advance,coordinated the Thai agent to reissue the certificate with electronic seal on the same day,and the goods were declared directly upon arrival,without paying any demurrage fee.

2.Port Customs Declaration: The "Core Link" for Accurate Tax Matching

Tax issues during the customs declaration stage are most easily overlooked.In 2026,Shanghai Customs updated the HS codes for 12 types of tropical fruits.Incorrect code filling will directly affect the tax rate.Manager Shu from Zhongshen is responsible for entering information into the customs declaration system,focusing on two tasks:

First,verify the HS code: For example,the code for fresh durians is 0808100000,and the tariff rate has two categories —— 5% with FORM E,and 15% without it; the code for fresh mangosteens is 0803900000,with a tariff rate of 3% (regardless of whether there is FORM E),but the import value-added tax is 9% for both.

Second,calculate tariffs and value-added tax: It is necessary to accurately enter the value,freight and insurance fees (CIF price) to avoid overpaying taxes due to incorrect price declaration.In March 2026,a Shanghai trading company declared customs on its own,underreporting the CIF price of fresh durians by 20%.After being checked by customs,it had to make up 18,000 yuan in taxes and also incurred a 0.5% late payment fee.When acting as an agent,Manager Shu will verify the prices on the bill of lading and invoice in advance to ensure the accuracy of the CIF price,and also assist in applying for tariff reductions (preferential policies for the ASEAN Free Trade Area).

3.Quarantine Inspection: The Key to Avoiding "One-Vote Rejection"

Quarantine requirements for Southeast Asian fruits are strict.In 2026,special tests for "Mediterranean Fruit Fly" and "Oriental Fruit Fly" were added.Unqualified goods will be directly destroyed or returned.The team led by Mr.Sheng from Zhongshen will do three things in advance:

• Book inspection time: Make an appointment with Shanghai Entry-Exit Inspection and Quarantine Bureau one day before the goods arrive,to avoid delays caused by queuing.On average,it is 2 days faster than enterprises making their own appointments;
• Prepare inspection samples: Extract 5-10 kg of samples for each variety,place them in special refrigerated containers,and maintain the temperature at 0-4℃ (for durians) or 2-6℃ (for mangosteens);
• Assist with on-site inspection: If it is found that the ventilation holes of the packaging do not meet the requirements (for example,durians need more than 10 ventilation holes),coordinate the port warehouse to temporarily replace the packaging to avoid return of goods.

In May 2026,10 containers of mangosteens imported by a Shanghai trading company were required to be returned by quarantine personnel because there were only 5 ventilation holes in the packaging.Mr.Sheng from Zhongshen coordinated the port warehouse to replace 200 compliant cartons within one hour,completed the inspection on the same day,and the goods were released smoothly,avoiding a loss of 500,000 yuan.

4.Tax Declaration and Payment Settlement: The "Final Barrier" in the Closing Stage

The closing stage of import taxation should not be taken lightly.In 2026,the State Administration of Foreign Exchange has strengthened the verification of trade authenticity.The payment must be completely consistent with the customs declaration form and contract.Mr.Dong from Zhongshen is responsible for tax declaration and payment settlement,focusing on two issues:

First,import VAT deduction: Obtain the special payment voucher for import VAT from the customs,and verify the name of the payment unit,tax amount and payment date.Incorrect information will lead to failure in deduction.In April 2026,an enterprise made a declaration on its own,and the name of the payment unit on the payment voucher was missing one character.Mr.Dong assisted in contacting the customs for correction,completed the deduction within 3 days,and avoided a loss of 12,000 yuan.

Second,payment settlement procedures: Provide the customs declaration form,contract,invoice and bill of lading.The foreign exchange bureau will verify whether the goods flow and capital flow are consistent.There was an enterprise that was denied payment by the foreign exchange bureau because the invoice amount was inconsistent with the customs declaration form.Mr.Dong coordinated the customs to correct the declaration data,and completed the payment within 2 days.
