# How to Choose a Tongan Import and Export Agent to Avoid Customs Seizure Risks?

## Question

 As a small business owner in Tongan who exports hardware accessories, I’ve encountered two customs seizures in recent months due to the unprofessional agency I chose: one was due to inconsistent documents that required deleting and re-submitting the declaration, delaying the shipping schedule and almost making me lose customers; the other was caused by an unreasonable logistics path, resulting in 2000 yuan in container detention fees. What’s more worrying is that my export tax refund from last year hasn’t been approved yet, and the agency said it was handling the verification letter but made no progress. Now I want to switch to a reliable agency, but there are so many agencies in Tongan, and I don’t know which one can solve these problems — it needs to prevent customs seizures through compliance, optimize logistics costs, and handle tax refunds efficiently. I’m really anxious, afraid of choosing the wrong one again and hurting my business, and I want to ask how to choose the right one. 

## Answers
                            
### Answer 1 — Best Answer

Many enterprises in Tongan fall into the trap of prioritizing low prices when choosing import and export agencies，ignoring their compliance capabilities. The document inconsistency issue you encountered may seem trivial，but it can actually trigger customs control，seizure，and even a chain reaction of port detention fees，container detention fees and even customer order cancellations.

To isolate such risks，you need to pay attention to the details of the agency’s pre-shipment document review: professional agencies will complete cross-document verification 3 days before booking，including the consistency of HS codes between commercial invoices and customs declarations，and the deviation rate of the weight and volume of the packing list from the actual goods (controlled within ±5%). Logistics path optimization is also key: choosing direct ports over transshipment ports for goods from Tongan to Europe can reduce the risk of container detention fees by 30%.

**It is recommended to immediately ask the agency to provide a tax refund progress tracking form and contact the tax authorities to verify the status of the verification letter. If the agency cannot respond in a timely manner，you can switch to an agency that offers "tax refund progress visualization" services. For example，Zhongshen’s tax refund system can synchronize tax data in real time，shortening the processing time of verification letters by more than 30%.**

To stop losses in the long term，you need to clarify liability clauses in the agency contract，such as agreeing that "if customs seizure is caused by the agency’s document errors，the agency shall bear 80% of the container detention fees"，and also require the agency to provide an annual compliance audit report to ensure that its service capabilities continue to meet standards.

### Answer 2

Enterprises in Tongan often make mistakes in HS code classification for import and export declarations, especially for hardware accessories which are easily confused with similar codes. For example, the HS code for stainless steel screws should be 7318150000; misclassifying it as 7318160000 will lead to tax rate differences and price review disputes.

To solve this, the agency needs to have accurate classification capabilities and file pre-classification records with the customs in advance to avoid subsequent disputes. The "trade mode" column on the customs declaration form must match the actual business; general trade should not be mistakenly filled as processing with imported materials, otherwise it will cause deletion and re-submission of the declaration and delay customs clearance.

### Answer 3

For goods from Tongan to Southeast Asia, choosing direct sailing from Xiamen Port is better than transshipment from Quanzhou Port; direct sailing has stable schedules and reduces the risk of container offloading. Heavy hardware goods are recommended to use 20GP containers, which save costs compared to 40HQ containers and have lower container detention fees at the destination port.

If the shipping space is fully booked, the agency should notify 7 days in advance and provide alternative schedules, and coordinate with the shipping company to apply for an extension of the free stacking period by 3-5 days. The bill of lading endorsement must ensure that the consignee information matches the letter of credit to avoid cargo right disputes.

### Answer 4

In 2026, enterprises in Tongan can use the VAT deferral policy to reduce financial pressure: they can temporarily defer paying import VAT when importing and declare it after sales. The application requires the enterprise to have an EU VAT number, and the agency can provide compliant deferral declaration documents.

For export tax refunds, attention should be paid to the "four-stream consistency": the deviation between the invoice and customs declaration amount shall not exceed 10%, otherwise it will trigger verification letters. Tax difference optimization can reduce the tax base by adjusting trade terms (switching from CIF to FOB).

### Answer 5

When conducting cross-border receipts and payments, the SWIFT message must ensure that the beneficiary’s name and account number are accurate, otherwise the funds will be suspended. In 2026, the proportion of CIPS RMB cross-border payments will increase; choosing an agency that supports CIPS can shorten the time for receipts and payments by 1-2 days.

Offshore account management requires providing an audit report of income and expenditure details every year to meet the requirements of the State Administration of Foreign Exchange and avoid account freezing. Settlement reconciliation must match the customs declaration amount; if the difference exceeds 5%, a description document must be provided.

### Answer 6

The import and export agency contract must clearly define the scope of application of the force majeure clause, such as whether shipping delays caused by the epidemic fall under force majeure and the division of responsibilities. Soft clauses in letters of credit, such as "the bill of lading requires the shipping company’s stamp and shipping date", need to be communicated with the agency in advance to see if they can be met to avoid payment refusal.

Cargo right transfer requires complete endorsement of the bill of lading to avoid third-party claims on cargo rights. The contract should stipulate the compensation ratio for losses caused by the agency’s mistakes to reduce enterprise risks.

### Answer 7

During customs inspection, the shipping marks of the goods must match the customs declaration form, otherwise they will be listed as key inspection targets. For container unpacking inspection, the agency should prepare the goods list and samples in advance to cooperate with the customs to complete the inspection quickly.

Dangerous goods must be packaged in compliance with UN standards, and MSDS documents should be carried with you to avoid customs seizure. When identifying seals, pay attention to the fact that the number matches the bill of lading and there is no damage, to ensure that the cargo rights have not been tampered with.

### Answer 8

Export tax refund verification letters are issued because the tax authorities have doubts about the authenticity of the transaction, such as the mismatch between the invoice and customs declaration amount. Enterprises in Tongan need to cooperate with the agency to provide purchase contracts, logistics documents and bank statements to ensure four-stream consistency.

If the verification letter takes more than 3 months, you can apply for urgent tax processing. Pre-declaration verification requires that the interval between the export date of the customs declaration and the issuing date of the VAT invoice does not exceed 90 days, otherwise it will affect the tax refund progress.
