Last year,we cooperated with Mr.Du,who runs Southeast Asian home goods import business.Previously,he hired a small agency whose quotation was 30% lower than the market average for tax-included import customs clearance.The agency promised all fees were fully covered,but after the cargo arrived at the port,it was selected by customs for inspection.Customs verified the existence of under-declared cargo value and wrong HS code classification.Finally,the total supplementary tax and fine amounted to RMB 120,000,the cargo was detained at the port for 37 days,missed the peak sales season and caused a loss of nearly RMB 400,000.

Core Operational Points for Tax-Included Import Customs Clearance and Declaration
In 2026,customs further intensifies verification on import declaration.Especially,the coverage of verification on declared value authenticity,HS code classification accuracy and certificate of origin compliance for tax-included imports has expanded from high-risk categories to general cargo.The following three core links must be strictly controlled during operation:
- Pre-audit of accurate HS code classification: In 2026,customs updated classification rules for nearly 2000 HS codes,with relatively large adjustments in categories of electromechanical products,chemicals and cosmetics.Pre-review of classification shall be conducted against the latest tariff catalogue before declaration.For categories requiring 3C certification and import license,relevant qualifications shall be completed in advance,to avoid return shipment or penalty caused by wrong classification.Last year we handled a batch of hardware tools imported from Germany.The HS code declared by the cargo owner himself had a tax rate of 8%,while our pre-audit found that the goods should be classified under a HS code with 13% tax rate.We adjusted the declaration in advance and avoided subsequent supplementary tax and penalty.
- Pre-matching with customs valuation logic: In 2026,the customs valuation system has been connected to global trade data interface,which automatically compares import declaration prices of the same category in the past 3 months.If the deviation exceeds 15%,the cargo will be arranged for inspection directly.Before submitting tax-included import declaration,prepare purchase contract,foreign exchange payment voucher,certificate of origin,freight and insurance documents in advance.If the declared value is relatively low,prepare a written explanation in advance to avoid being identified as under-declaration or omission by the system.For goods from RCEP member countries,verify the authenticity of the certificate of origin in advance,and qualified goods can enjoy preferential agreement tariff to further reduce import cost.
- 100% verification of document consistency: All elements including brand,model,material and specification on all declaration documents must be completely consistent with the physical goods.In particular,the information on packing list and invoice provided by the overseas shipper shall be cross-verified with domestic purchase order information in advance.In 2026,the penalty standard for inconsistent declaration elements is raised from the original 5% of cargo value to 10%,and any inconsistency will directly result in a fine.
Common Risk Warnings for Tax-Included Import Customs Clearance in 2026
Many cargo owners choose tax-included import service to simplify procedures and lock cost.However,if the engaged agency is not professional,they are very likely to fall into the following traps:
First is the compliance risk of under-declaration and omission.Many low-price agencies cut costs by under-declaring cargo value and applying low-duty HS codes.Once detected by customs,the importer will not only need to pay supplementary tax and fine,but also be listed in the import dishonesty list.Afterwards,all his imported goods will be 100% arranged for inspection,which will affect long-term business.

Second is the hidden charge trap.Many agencies only quote basic tax-included fees at the very beginning,but add various extra charges such as document exchange fee,demurrage fee,expedited inspection fee and forklift fee after the cargo arrives at the port.The total final cost will be over 20% higher than that of formal agencies.
Third is the cost risk of omitted anti-dumping duty.In 2026,anti-dumping duty rates for certain categories from regions including Europe,America and Southeast Asia have been adjusted.For example,the anti-dumping duty rate for aluminum products,photovoltaic modules and chemical raw materials can reach up to 200%.If the agency fails to conduct full verification in advance and the anti-dumping duty is not included in the tax-included quotation,the cargo owner will be required to pay extra supplementary duty afterwards,leading to doubled cost directly.

Last year,we served Manager Yao,who is engaged in import of European laboratory instruments.The previous agency he cooperated with spent more than 10 days on customs clearance every time,and often charged various extra fees.In March 2026,he turned to us.We confirmed the HS code classification for the instruments in advance,submitted purchase contract and foreign exchange payment voucher to customs for pre-valuation verification.The cargo was cleared and released within 2 days after arrival,and the total cost was 8% lower than before.He has entrusted all subsequent import business to us.
