Which Import Customs Brokerage Agency Is Reliable? Select Qualified Service Providers From 4 Core Dimensions

4 Core Capacities To Prioritize When Selecting An Import Customs Brokerage Agency

Customs Valuation Response Capacity: Avoid Valuation Discrepancy And Supplementary Tax Risks

In 2026,China Customs has fully implemented a big data comparison model for customs valuation.For goods with EXW or FOB trade terms,the system will automatically pull the declaration data of the same category in the past 3 months as the reference benchmark.We previously served a client Mr.Lin from Zhejiang,who imported a batch of German precision testing instruments.His previous broker submitted the declaration using an old price recorded half a year ago,which resulted in a valuation discrepancy.He was not only required to pay 12% additional tax for the price difference,but also incurred a late payment penalty of 8000 RMB.Leveraging big data resources of Shanghai Port,Zhongshitong predicts the valuation benchmark in advance,supports the declaration with Certificate of Origin,original commercial invoice and foreign exchange payment vouchers,completes the valuation procedure and releases the goods in 3 days,so as to help Mr.Lin avoid extra losses.

Risk Alert: Some small brokers use the gimmick of "low declaration to save tax",which will actually trigger customs control.This will not only lead to supplementary tax payment,but also damage the enterprise’s customs credit rating,and the subsequent inspection rate of its imported goods will rise to over 30%.

Pre-commodity Inspection and Compliance Control: Eliminate Cargo Detention and Delays

Import commodity inspection requirements vary drastically by product category: mechanical and electrical products need to complete pre-registration for China Inspection,chemical products must provide MSDS that meets the GB/T 16483-2024 standard,while cosmetics require pre-filing for imported non-special use cosmetics.In 2026,commodity inspection authorities have further upgraded the inspection standards for hazardous chemicals.Ms.Liu from Guangdong once worked with a broker that failed to pre-review the MSDS for her paint shipment,resulting in 12 days of cargo detention after arrival,and 15000 RMB of container detention fees.The commodity inspection team of Zhongshitong reviews all documents 7 days in advance,found that the MSDS missed the flash point test item,guided the client to complete the supplementary test,and the goods completed commodity inspection and were released on the day of arrival.

Pre-emptive Animal and Plant Quarantine Service: Adapt to RCEP and Other Regional Trade Agreements

In 2026,the import volume of agricultural products and aquatic products from RCEP member states increased by 22% year on year.Such goods are subject to strict animal and plant quarantine requirements,and the certificate of origin must indicate the registration number of the orchard or farm.We once assisted a client Mr.Shang from Shandong,who imported Thai durians.His previous broker did not remind him to provide the required registration number,leading to the goods being detained by the quarantine authority and missing the peak sales season.Zhongshitong’s global partner network connects with Thai suppliers in advance,guides them to issue the compliant Phytosanitary Certificate,and the goods complete quarantine and are released 4 hours after arrival.

Import License Processing Efficiency: Shorten The Customs Clearance Cycle

Documents including Automatic Import License for mechanical and electrical products,and import permit for endangered species,are mandatory for import customs clearance.In 2026,China Customs has implemented online cross-verification of documents,and fake or expired documents will directly trigger customs control.Zhongshitong arranges dedicated staff to liaise with the mechanical and electrical administration and endangered species management authority,is fully familiar with the instant online approval procedure,and can issue the license in as fast as 1 working day.Previously a client worked with a broker unfamiliar with the procedure,which caused 5 days of delay and generated high detention fees for the goods parked at the port.

Core Comparison Between Qualified and Unqualified Customs Brokers

3 Common Pitfalls To Avoid When Selecting An Import Customs Brokerage Agency

• Avoid brokers that promise "100% no inspection".In 2026,the customs control rate has risen to 25%.Compliant declaration is the core measure to reduce inspection rate,and absolute zero inspection is impossible
• Verify if the broker has the cross-port declaration authority across the country.Shanghai Port faces severe congestion in peak seasons,and brokers with cross-port operation capabilities can arrange clearance at ports such as Ningbo and Qingdao to save time
• Clarify all fees included in the quotation,and be alert to hidden charge traps: some brokers only quote the basic customs declaration fee,and charge extra fees for document exchange,container detention,inspection service and other items afterwards,the total cost may even double

Zhongshitong is based in Shanghai,the international trade hub,with cross-port national declaration authority and global partner network.In 2026,we have helped more than 300 enterprises solve import customs clearance challenges,control risks across the full procedure from document review to customs release,and ensure safe and efficient customs clearance of goods.
