What are the core nodes of the import customs declaration process? How to effectively avoid the risks of port detention and customs detention?
or complex compliance issues.
clearance and fund security.
I am an e-commerce procurement executive who just ventured into imported beauty business. Last month, I air-freighted a batch of air cushions and lipsticks from South Korea for the first time. As a result, the cargo was detained for 3 days due to a wrong HS code on the customs declaration form.
I not only incurred over 2,000 USD in port detention fees, but also missed the stock preparation period for the June 18 Grand Promotion, resulting in a direct loss of over 100,000 USD in sales. I was severely reprimanded by my boss. Now I need to import a batch of high-end essences from Europe, with a higher cargo value and shipped by sea.
I have stayed up all night for several nights researching information but still feel confused and extremely anxious, fearing that problems will occur again. I want to know exactly how to handle import customs declaration? What should I pay attention to in each link from pre-declaration document preparation to customs clearance and final delivery? Also, if I encounter abnormal situations again, how can I resolve them quickly to avoid losing money like last time?

First，details of pre-declaration document review: Accurate HS code classification must be completed in advance. Refer to the 2026 version of the Customs Tariff，and check one by one based on the cargo's components，usage，packaging and other information to avoid customs detention triggered by coding deviations，at the same time，verify the consistency of the certificate of origin，packing list，commercial invoice and trade contract，ensure that the format of the certificate of origin is compliant，and the invoice amount fully matches the actual transaction amount，so as to eliminate the hidden danger of discrepant documents.
Core process handover: Submit the pre-reviewed documents to the customs broker 3 days prior to cargo arrival，and simultaneously coordinate with the port yard to confirm the cargo arrival time，ensuring that the information entered on the customs declaration form is completely consistent with the manifest and bill of lading，to avoid returned declarations due to information deviations. After declaring to customs，track the status of customs document review in real time. If a customs inspection hold is triggered，immediately cooperate in providing supplementary materials such as product manuals and composition test reports.
Emergency response plan: In case of customs detention，obtain the customs detention notice first. If the problem is due to documentary defects，immediately supplement the corrected materials and re-declare，if there is a dispute over the HS code，entrust a qualified institution to issue a product classification opinion. If there is a risk of port detention，apply to the terminal in advance for an extension of the free detention period，or coordinate a temporary yard transfer to reduce costs.
Final compliance closure: Pay the duties and taxes promptly after customs clearance，obtain the release notice to arrange warehouse pickup，and archive all documents for at least 3 years for subsequent customs audits，ensuring a full compliance closed-loop process.

Price valuation disputes are common complex issues in import customs declaration. If the declared price is lower than the customs valuation standard, it will trigger the price inquiry procedure, leading to customs clearance delays. It is necessary to prepare supporting materials such as trade contracts, payment slips, and cost breakdowns in advance to prove the authenticity of the declared price.
If encountering customs system push-back, supplement the explanation within the specified time limit to avoid canceling and re-filing the declaration due to overdue. For goods declared through integrated customs declaration, ensure that the customs data of the declaration place and destination place are synchronized to avoid ledger hanging issues caused by data disconnection. In addition, when making a secondary declaration, pay attention to the consistency between the adjusted information and the original manifest to avoid logical contradictions.

The efficiency of import customs declaration is directly related to the choice of logistics route. If choosing a transit route, confirm the customs requirements of the transit port to avoid cargo detention caused by the transit rules of the transit country. After the cargo arrives at the port, complete the customs declaration within the free detention period. If the expected customs clearance time is long, apply to the shipping company in advance for an extension of the demurrage exemption period to reduce costs.
For full container load (FCL) goods, check that the seal number on the bill of lading is consistent with the actual cargo's seal number to avoid cargo ownership disputes caused by abnormal seals. In case of container offloading, adjust the customs declaration timing promptly and update the manifest information simultaneously to avoid returned declarations due to inconsistencies between the manifest and the customs declaration form.

Duties and taxes account for the largest proportion of the costs in import customs declaration. Reasonably utilizing the VAT deferral policy can alleviate the cash flow pressure of enterprises. Eligible enterprises can apply to pay value-added tax only after the goods are sold, without prepaying at the time of customs clearance.
In addition, if the goods meet the rules of origin, they can enjoy tariff reductions with valid certificates of origin. It is necessary to ensure that the issuing authority of the certificate of origin is compliant and the domestic content of the goods meets the requirements.
For goods involved in cross-border related party transactions, declare the price in accordance with the arm's length principle to avoid tax audits caused by transfer pricing issues. At the same time, promptly declare and pay import consumption tax to avoid late payment penalties due to overdue payments.

The compliance of import customs declaration is directly linked to payment and settlement. Ensure that the value on the customs declaration form is consistent with the payment amount to avoid foreign exchange settlement and account balancing issues caused by amount deviations.
If using the Cross-Border Interbank Payment System (CIPS), ensure that the message information matches the customs declaration form, including the product name, quantity, amount, etc. For payments made through offshore accounts, retain payment vouchers and trade background materials for verification by foreign exchange administration departments. In addition, complete the import payment verification promptly to avoid subsequent payment and settlement restrictions caused by uncompleted verification.

The legal risks in import customs declaration mainly focus on trade contracts and intellectual property rights. The trade contract should clearly specify the clauses for dividing customs declaration responsibilities to avoid disputes caused by unclear responsibilities of both parties. If the imported goods involve intellectual property rights, complete the customs intellectual property protection registration in advance to avoid customs detention caused by infringement.
For goods settled by letter of credit (L/C), ensure that the information on the customs declaration form is consistent with the L/C terms to avoid dishonor caused by discrepant documents. In addition, if customs clearance delays are caused by force majeure, retain relevant supporting materials promptly to claim exemption in accordance with the contract clauses.

If customs inspection is triggered during import customs declaration, prepare materials such as product manuals and composition test reports in advance to cooperate with the customs officers' inspection work. For goods with abnormal machine inspection, apply for unpacking inspection promptly to avoid increased port detention fees due to delays. Check that the cargo information on the inspection notice is consistent with the actual cargo.
If any information discrepancy is found, communicate with the customs broker immediately to make adjustments. For goods requiring inspection and identification, confirm the qualification of the inspection institution and follow up on the issuance time of the inspection report to avoid customs clearance stagnation caused by report delays. In addition, pay attention to the integrity of the seal, and re-seal the cargo promptly after inspection to avoid cargo ownership risks.
