2026 TPC Import Agent Full-Process Guidelines, Customs Declaration Compliance Tips Summary

Core Processes of TPC Import Agent and 2026 Regulatory Requirements

Last month,we helped Mr.Guo from Suzhou handle a shipment of TPC boards imported from Japan.The small agent he had previously hired made an error in HS code classification during declaration,misclassifying thermoplastic composite materials in Chapter 39 as miscellaneous chemicals in Chapter 38.This not only led to overpayment of 12% import tariffs but also triggered a customs controlled inspection.The goods were stuck at the port for 12 days,with demurrage fees alone exceeding 20,000 yuan.In 2026,customs’ verification of declaration elements for industrial composites has been fully upgraded.As a basic material widely used in electronics,automotive,and aerospace industries,TPC requires additional submission of three types of supporting documents during declaration: material composition ratio,processing technology,and specific application.Inconsistent information will trigger price verification or goods seizure.

The standard process of TPC import includes four stages: first,overseas pickup and international logistics,covering all trade terms such as EXW,FOB,CIF; second,document pre-auditing,including verification of Certificate of Origin,MSDS,trade contract,invoice,packing list; third,port declaration,including four steps: customs price verification,CIQ pre-inspection,tax payment,inspection; finally,domestic delivery and subsequent foreign exchange payment,document filing.

Cost Comparison of Different Operation Modes for TPC Import Agent

Practical Implementation Guide for TPC Import Agent

• Conduct HS code pre-auditing in advance: In 2026,customs has added two mandatory declaration elements for TPC: material composition and processing technology.Before submitting documents,ensure 100% match between MSDS,third-party composition test reports and declaration elements to avoid classification deviations triggering price verification control.Once misdeclaration is confirmed,it will also affect the enterprise’s customs credit rating.
• Pre-submission document review: For TPC imported from the EU and the US,check in advance if the product falls within the anti-dumping list.If meeting RCEP origin criteria,apply for preferential Certificate of Origin in advance,which can enjoy zero tariff at maximum; the saved taxes and fees can cover the full agency cost.
• Port inspection anticipation: At Shanghai Port in 2026,the random inspection rate for imported industrial materials is approx.8%.The agent needs to pre-verify the goods’ packaging,marks,brand and model to avoid goods seizure due to inconsistency between declaration information and actual goods,which would lead to additional expenses such as demurrage fees and terminal storage fees.

Core Service Advantages of TPC Import Agent

Zhongshitong is headquartered at the core hub of Shanghai international trade,with cross-region declaration authorization at all first-class ports nationwide,and has cooperative agent networks in over 120 countries and regions globally.We can provide end-to-end services from overseas door pickup,international transportation,port customs clearance to domestic delivery to factory,eliminating the need for enterprises to coordinate multiple service providers and reducing communication costs.

Addressing customers’ most concerned price verification disputes,we will collect national import transaction data of TPC products with the same specification for the past 3 months,and provide a reasonable declaration price range to customers in advance to avoid being questioned by customs for under-declaration.Previously,we helped Ms.Hao from Zhejiang handle a shipment of TPC pellets imported from Germany; during declaration,customs required an additional tax payment of 180,000 yuan.We submitted the original manufacturer’s transaction vouchers,foreign exchange payment slips,and import transaction records of the same category,and completed the price verification appeal within 24 hours,ultimately with no additional taxes and fees incurred,and the goods were released on the same day.

Risk Warnings for TPC Import Agent

First,pay attention to compliance red lines.In 2026,customs has increased the composition inspection ratio for imported TPC to 15%,and concealing composition or under-declaring cargo value is prohibited.Once verified,the minimum penalty is goods detention and rectification; the maximum penalty is inclusion in the list of untrustworthy enterprises,leading to a 100% inspection rate for all subsequent imported goods,causing significant impacts on the enterprise’s normal operations.

Second,beware of the delivery order fee trap.Many designated freight forwarders charge additional document fees and operation fees during the delivery order exchange process,with rates 2-3 times higher than the market.We have signed unified charge standards with global agents in advance,and all fees are disclosed in advance,so there will be no hidden charges.Additionally,with increased exchange rate fluctuations in 2026,we can provide currency hedging services to help enterprises avoid exchange rate losses in the foreign exchange payment stage and lock in import costs.

If enterprises have TPC import needs,it is recommended to submit basic cargo information 7 days in advance.We will conduct free HS code pre-classification and compliance plans,and identify all potential risks in advance to ensure smooth cargo clearance.
