Mr.Ma called for consultation last week.His furniture factory has received its first order from Bangkok,Thailand,and he is uncertain about the export customs declaration fees.This is actually the real situation for many export enterprises -- the figures on the quotation look simple,but there are a lot of details behind them.As one of the fastest growing trading partners in Southeast Asia in 2026,the composition of Thailand’s export customs declaration fees is far more complex than it seems.Figuring out where the money is spent,what can be saved and what cannot be saved is directly related to the profit of the order.

Customs Official Fees: Mandatory Costs Charged by the Government

This part of the fee is administrative charge collected by Thailand Customs and relevant departments in accordance with the law,which is mandatory and standardized,and the agency has no right to reduce or adjust it.In 2026,Thailand Customs adjusted its supervision policy for imported goods,and the inspection rate of some categories has increased,so enterprises need to reserve this part of the budget in advance.

Tariff is the largest component.Thailand applies different tariff rates to different types of Chinese goods.Furniture currently enjoys preferential tariff rates under the ASEAN-China Free Trade Agreement,provided that export enterprises can provide complete certificate of origin documents.If the documents are incomplete,the customs will levy tax at the most-favored-nation tariff rate,and the difference between the two may reach 10-15 percentage points.The calculation base of tariff is CIF value,that is,cargo value plus freight plus insurance premium,which directly affects the final tax amount.

The current standard VAT rate is 7%,which is levied on the total amount of CIF value plus tariff.It should be noted that Thailand Customs is very strict in the review of declared value,and a new price evaluation system was launched in 2026,which will automatically warn declarations lower than the market price.If the declared value of Mr.Ma’s furniture is obviously low,he may face value assessment and tax supplementation,which is an extra cost that many new exporters never expect.

Inspection fee is another mandatory expenditure.Thailand Customs adopts a combination of random inspection and key supervision,and the inspection rate for wooden packaging has been raised to about 30% in 2026.Once selected for inspection,in addition to the inspection fee of the customs itself,there will be wharf lifting fee,unsealing fee,re-sealing fee,etc.totaling about 2000-4000 THB.If the goods need to be tested,the testing fee is calculated separately,and the testing fee for food may be as high as more than 10,000 THB.

Fumigation fee is charged for wooden packaging materials.Thailand requires all wooden packaging to be fumigated and affixed with IPPC mark.The fee is charged per container,and a 20ft container costs about 1500-2000 THB.Many enterprises use non-wooden packaging to save this cost,but it should be noted that if the actual packaging is inconsistent with the declaration,it will be identified as a violation during inspection,and the fine will far exceed the fumigation fee itself.

Agency Service Fee: The Value Embodiment of Professional Services

This part is the remuneration paid to the customs broker,covering the whole process of service from order receiving to release.In 2026,competition in Thailand’s customs brokerage industry has intensified,but the charging standards have become more transparent,mainly because customers’ price comparison ability has increased,forcing regular companies to mark prices clearly.

Customs declaration fee is the basic charge,calculated per shipment.At present,for the route from Shanghai to Thailand,the quotation of regular customs brokers is between RMB 800-1500 per shipment,and the difference mainly depends on the complexity of the goods.General cargo has lower charges,and if it involves license management,brand authorization,anti-dumping goods,the fee will increase accordingly.Mr.Ma’s furniture is general cargo,which can be charged according to the standard rate.

Document fee includes the cost of making invoices,packing lists,certificates of origin and other documents.In 2026,Thailand Customs fully promotes electronic documents,but paper documents still need to be backed up.The document fee is usually charged per copy,RMB 50-100 per copy.If the customer provides the documents by himself and the customs broker is only responsible for verification,this fee can be waived.

Operation fee is the cost for the customs broker to coordinate with the fleet,wharf and shipping company.Major ports in Thailand such as Laem Chabang and Bangkok Port have their own operation process characteristics,and customs brokers need to be familiar with local rules to avoid delays.The operation fee is generally charged per container,RMB 300-500 for 20ft containers and RMB 500-800 for 40ft containers.If the goods require special treatment,such as refrigerated container loading supervision,dangerous goods isolation,the fee will be increased additionally.

Consultation fee is charged for special problems.For example,the anti-dumping issue of furniture that Mr.Ma inquired about,although Chinese-made furniture is not on Thailand’s anti-dumping list in 2026,the customs broker needs to check the latest policy and issue a written opinion,which usually costs RMB 500-1000.For conventional problems,regular customs brokers generally provide free answers.

Cost Transfer Under Different Trade Terms

Under FOB terms,the seller only needs to bear all costs before the goods are loaded on board,including export customs declaration fee,document fee and inland freight.If Mr.Ma does FOB Bangkok,he only needs to pay the customs declaration fee in RMB,and the fee in THB is borne by the buyer.However,in actual operation,many Thai buyers require sellers to provide DDP (Delivered Duty Paid) quotations,at which time all costs will be passed on to the seller.

Under CIF terms,the seller needs to pay sea freight and insurance premium,but the customs fee structure remains unchanged.In 2026,Thailand’s insurance review for CIF goods has become stricter.If the policy information is incomplete,the customs may require re-insurance,resulting in additional costs.Some customs brokers will recommend customers to buy local insurance in Thailand.Although the premium is slightly higher,claim settlement and customs clearance are smoother.

Hidden Costs: Expenditure Traps Beyond the Quotation

This part of the cost is the most likely to cause disputes,and it is also the key to distinguish the professionalism of customs brokers.In 2026,Thailand Customs has strengthened the supervision of customs brokers,and the phenomenon of illegal charging has decreased,but hidden costs still exist.

Expedited fee is the most common hidden cost.Normally,customs clearance by Thailand Customs takes 1-2 working days.If the customer requires same-day release,the customs broker needs to arrange special personnel to follow up,and the fee will increase by 50%-100%.If Mr.Ma’s furniture has a tight shipping schedule and requires expedited customs clearance,he should confirm the expedited fee standard with the customs broker in advance.

Storage fee is incurred due to inspection detention.The free storage period at Thai ports is usually 3-5 days,and charges are incurred per day after the expiration.If the goods are inspected,the customs clearance time will be extended,which is easy to generate storage fees.Regular customs brokers will specify the free storage period and overdue rate in the quotation,and some even promise to bear the overdue fee caused by customs declaration reasons.

Document modification fee is another common item.If the document information provided by the customer is wrong and the customs declaration form needs to be modified,Thailand Customs will charge a document modification fee of about 500-1000 THB per time.Some customs brokers offer very low initial quotations to attract customers,but will make up for profits through document modification fees and other means.Mr.Ma needs to pay special attention to ensure the accuracy of the documents when providing them to avoid repeated modification.

Special treatment fee is charged for sensitive goods.For example,if furniture contains endangered wood components,additional CITES certificate is required,which costs about RMB 3000-5000.Food requires health certificates,and cosmetics require registration and filing,which will incur additional costs.Regular customs brokers will clearly inform all potential costs when receiving orders,rather than putting forward them at the time of customs clearance.

Transparent Charging: Key Strategy to Avoid Traps

In 2026,Thailand’s customs brokerage industry is undergoing reshuffle,and small companies that rely on vague quotations to survive are gradually being eliminated.When choosing a customs broker,enterprises need to establish a systematic evaluation standard.

First,ask the customs broker to provide an itemized quotation instead of a package price.The itemized quotation can clearly see where each sum of money is spent,what is necessary and what can be optimized.The quotation Mr.Ma receives should include: details of customs official fees,details of agency service fees,and estimation of possible miscellaneous fees.If the customs broker only gives a total price,there is probably hidden moisture in it.

Second,confirm the validity period of the quotation.Thailand’s customs policy is adjusted frequently.Some customs brokers use low prices to attract customers,but note that "prices are adjusted with policy changes".Regular companies will promise that the quotation is valid for at least 3 months,and notify customers in advance when the policy changes.Zhongshen’s current practice is to indicate on the quotation "valid for the second quarter of 2026,and any cost increase caused by policy changes during this period shall be borne by our company".

Third,verify the qualification and reputation of the customs broker.In 2026,Thailand Customs implements classified management for customs brokers,and Class A customs brokers enjoy fast customs clearance treatment,and the inspection rate is relatively low.Enterprises can ask customs brokers to provide qualification certificates,and understand their service records through industry reputation.Companies that are frequently complained by customers for unclear charges should be carefully selected even if their quotations are lower.
