Breakdown of High-Frequency Export Customs Brokerage Issues in 2026

I.Core Issues at the Declaration Stage

Sorting Out High-Frequency Issues in Export Customs Brokerage in 2026, Full Guide for Foreign Trade Enterprises to Avoid Risks in Compliance Declaration

Declaration is the first link of export customs brokerage,and also the link with the highest proportion of problems.The 2026 data on rejected declarations for exports at Shanghai Port shows that 82% of rejected declarations come from low-level errors in the declaration stage.Many enterprises try to cut costs by saving a few hundred RMB of customs brokerage fees,but end up with losses of tens of thousands or even over 100 thousand RMB afterwards.The following are the three most common issues at the declaration stage:

Issue TypeDirect Consequences2026 Compliance Handling Solution
Incorrect HS Code ClassificationRejected declaration,supplementary tax payment,overpaid or underpaid tax due to incorrect tax rate application,and direct regulatory alert triggered for commodities included in the anti-dumping listSubmit product parameters,usage and materials to the broker 3 working days in advance for pre-classification,and conduct pre-verification through China Inspection and Certification Group for mechanical and electrical products in advance
Declared Elements Inconsistent with Actual GoodsGoods detained during inspection,case transferred to anti-smuggling department,brand declaration errors will be directly handled as trademark infringement,with goods confiscatedCheck brand,model and origin information before container stuffing,take photos for record,and cross-verify information on customs declaration form,packing list and invoice before submission
Irregular Completion of Certificate of OriginTariff reduction unavailable for exports to RCEP member states,additional anti-dumping tax payable,and some countries will directly return the goodsConfirm tariff preference requirements with destination country clients in advance,ensure all content on the certificate of origin is fully consistent with the customs declaration form,and the signature and seal meet the requirements of the corresponding destination country

The three types of issues above account for 72% of total rejected export declarations at Shanghai Port in 2026.Many enterprises consider declaration as a simple form-filling task,but in fact,even a wrong letter in a product model may cause cascading losses afterwards.Last year,we worked with Mr.Hou,who runs a hardware tool export business.His first batch of goods was shipped to Vietnam,and he hired a local small broker to handle customs declaration,who randomly classified the goods under general metal products category.During Vietnam customs clearance verification,it was found that the goods were hand tools included in the anti-dumping list.As a result,the 10% RCEP tariff reduction was not applicable,an extra 17% anti-dumping tax was levied,and the goods were detained at the port for 14 days.Combined with container detention charges and storage fees,the total loss reached nearly 120,000 RMB.Later,he turned to us,we re-conducted product classification for him,and coordinated with our partner broker in Vietnam to submit material certificates.All subsequent 12 batches of goods successfully enjoyed the tariff reduction,saving nearly 200,000 RMB of total costs.

II.Issues in Inspection and Destination Country Customs Clearance

In 2026,the national average export inspection rate at all ports increased by 7% year on year,with three issues prioritized for verification: under-declared or falsely declared goods value,trademark infringement,and inconsistent declared elements.Once the goods are selected for controlled inspection,it takes at least 3 to 5 days for handling.If the inspection period coincides with public holidays in destination countries such as Christmas or Ramadan,port detention costs will directly triple.Three pre-verification steps must be completed before export customs brokerage,which can reduce 90% of inspection and goods detention risks:

  • Submit full set of product materials 3 days before container stuffing,including material,usage,brand,model,and power rating (for mechanical and electrical products) to the broker for pre-classification and declared element verification,and submit required certification documents such as CE and SNI for products with certification requirements
  • Confirm the latest tariff policies and certification requirements with destination country clients.In 2026,the EU and multiple Southeast Asian countries have updated market access standards for home appliances and hardware products.It is necessary to verify in advance whether the certification is within the validity period and whether product labels meet local requirements
  • For collection terms under EXW and FOB,confirm the property right control node with the broker in advance,and fill in the enterprise’s own name as the consignor on the customs declaration form to avoid the risk of release of goods without original bill of lading

In 2026,trade regulatory rules across all countries are tightening.The EU updated its CE certification catalogue this year,adding mandatory certification requirements for 12 new categories of hardware and home products.Indonesia and Malaysia in Southeast Asia also raised the verification standards for imported goods declaration.Without checking corresponding requirements in advance,the probability of goods being directly returned after arrival at the port exceeds 40%.Zhongshitong is headquartered in Shanghai,and our efficiency of synchronizing the latest customs policy updates is 2 to 3 days faster than ordinary brokers.We support off-site declaration at all ports across China,and have partner broker networks in 230 destination ports worldwide.We can obtain the latest regulatory requirements of destination countries 7 days in advance,and adjust declaration documents accordingly to avoid problems after goods arrival.

III.Subsequent Tax Refund and Foreign Exchange Collection Risks

Many enterprises tend to ignore the linkage between customs declaration and subsequent tax refund as well as foreign exchange collection.In 2026,cross verification of information on customs declaration form,input invoice and foreign exchange collection slip is added to export tax refund verification dimensions.As long as any inconsistency is found in product name,specification or quantity between the customs declaration form and the input invoice,the application will be sent back for re-examination,and serious cases will result in direct cancellation of tax refund qualification.There are also foreign exchange collection risks.Under EXW terms,many enterprises believe that they have fulfilled their obligations once the goods are handed over to the freight forwarder.If the property right is not properly controlled during customs brokerage,the risk of release of goods without original bill of lading will easily occur.Last year,Ms.Ling who runs a clothing export business encountered this problem.The client picked up the goods immediately after arrival at the port,and the payment of more than 300,000 USD was delayed for 6 months before full collection.

Risk Warning: Many small brokers now offer customs declaration quotes 30% to 50% lower than market average,but there are a lot of hidden fees behind the low price.For example,they charge 2000 RMB per declaration amendment (the normal market price is 300 RMB per amendment),1500 RMB per inspection service (the normal market price is 500 RMB per ticket),and add premium to container detention charges and storage fees.The total comprehensive cost is 2 to 3 times higher than that of regular brokers,and no one takes responsibility after problems occur,since most small brokers do not have compensation capacity.All our charges are clearly listed in advance with no hidden fees,and we conduct 3 rounds of cross verification before declaration,with a rejected declaration rate less than 1/10 of the industry average level.
