How to Standardize the Whole Process of Import Customs Clearance to Effectively Avoid Port Detention and Seizure Risks?
or complex compliance issues.
clearance and fund security.
I am the owner of a small fine chemical raw material wholesale business based in Shanghai. Last month, I imported a shipment of modified resin from Germany for the first time and hired a small agency to handle customs clearance. As a result, a key item of MSDS was missed in the documents, and the cargo was detained for 7 days after arriving at the port.
I not only paid more than 20,000 RMB in port storage fees, but also missed the delivery deadline for my downstream customer and paid 50,000 RMB in breach of contract penalty. Now I am going to import another batch of the same raw material from South Korea, and I am really afraid of running into problems again.
I want to ask how to handle import customs clearance to avoid similar problems? For example, how to review documents, how to connect process nodes, what to do when abnormalities occur, and are there any policies that can be used to cut costs?

First of all，you need to complete refined pre-audit of supporting documents，which is the core prerequisite for customs clearance. For chemical products such as the modified resin you import，you need to focus on verifying 16 core items of the MSDS report，especially hazard classification，component composition，transportation precautions，etc. At the same time，you need to check the information consistency of certificate of origin，bill of lading，commercial invoice and packing list，to ensure that fields such as commodity name，HS code，quantity and weight are fully matched，and avoid triggering customs control due to inconsistent documents.
Core process nodes need to be connected seamlessly. 72 hours before cargo arrival at the port，you need to submit pre-audited documents to the Customs Single Window for advance declaration，to avoid congestion caused by centralized declaration after arrival. After the cargo arrives at the port，cooperate with the customs broker to complete electronic data comparison. If inspection is required，prepare samples，product manuals and other supporting materials in advance to ensure efficient inspection. For tax payment，you can choose Tariff Guarantee Insurance to achieve "release first，pay later" and shorten customs clearance time.
You need to formulate an abnormal disposal plan in advance. If you encounter abnormalities such as failed document review，customs control inspection，tax rate adjustment，etc。contact a professional customs clearance team immediately. For document problems，you can complete modification and re-declaration within 12 hours，for abnormal inspection results，you can provide a compliance report issued by a third-party testing institution as proof，if there is a risk of滞港，you can apply for an extension of the free storage period in advance to avoid high port storage fees.
After customs clearance is completed，you need to properly keep all customs documents，tax payment certificates，inspection records and other materials for no less than 5 years. At the same time，check whether the actual status of the goods matches the declaration information to ensure full compliance throughout the process. If you are eligible for policy dividends，you can apply for Import VAT Deferral to ease your enterprise's capital pressure.

Customs price verification is one of the core risk points in import customs clearance. A common mistake is that the transaction price declared by the enterprise does not include relevant expenses such as packaging fees and royalty fees, which will trigger customs price verification queries and even lead to declaration cancellation and re-filing.
If customs determines that the price is underreported, the enterprise not only needs to make up the tax difference and late fee, but also will damage the enterprise's customs credit rating. For such situations, you need to sort out all relevant expense vouchers related to the goods in advance, including contracts, payment receipts, invoices, etc., to ensure that the declared price meets the customs-approved transaction price criteria; if you encounter a price verification dispute, you can submit industry price research reports, price certificates from third-party assessment institutions and other materials to cooperate with customs in price negotiation, to avoid unnecessary penalties.

The connection between import customs clearance and logistics routes directly affects customs clearance efficiency. If you choose a transit route, you need to confirm the free storage period and detention charge standard of the transit port in advance to avoid additional costs caused by transit delay. For the chemical raw materials you import, it is recommended to prioritize direct routes to reduce title risk in transit links.
If you cannot complete customs clearance in time after cargo arrival, you can apply to the shipping company for an extension of the free storage period in advance. Generally, by submitting a written application and relevant supporting materials, you can extend the free storage period from the conventional 7 days to 14 days, effectively reducing port and container detention costs. At the same time, you need to ensure the completeness of bill of lading endorsement to avoid delivery obstruction caused by inconsistent endorsement.

The import VAT deferral policy launched by Shanghai Customs District for imported goods in 2026 can effectively ease enterprises' capital pressure. Enterprises do not need to pay import VAT during customs clearance, but declare and deduct it within the tax filing period. To apply for this policy, enterprises need to meet the requirements of being a general VAT taxpayer, completing customs credit rating filing, etc. After submitting relevant application materials, you can complete the filing on the Customs Single Window, and enjoy the deferral benefit after successful filing.
In addition, if your imported goods are in the encouraged industry catalog, you can apply for tariff reduction. You need to submit the industry certification to the National Development and Reform Commission in advance to confirm compliance with policy requirements and effectively reduce customs clearance costs.

Import customs clearance and cross-border payment and settlement must remain compliant and consistent. After cargo clearance, you need to complete the payment procedures within the specified period, and the payment amount must be consistent with the declared amount on the customs declaration, to avoid compliance risks caused by exchange differences. For your chemical raw material import business, if you use cross-border RMB payment, you can complete the payment via the CIPS system to shorten the payment cycle and reduce exchange rate fluctuation risk.
At the same time, you need to keep payment receipts, customs declarations, contracts and other materials to ensure the payment and settlement process complies with the regulations of the State Administration of Foreign Exchange. If you encounter foreign exchange verification, you can provide relevant supporting materials in time to avoid being listed as an abnormal payment and settlement entity.

It is necessary to pay attention to intellectual property compliance in import customs clearance. If the modified resin you import involves patented technology, you need to file for intellectual property customs protection with customs in advance to avoid cargo detention due to suspected infringement.
In addition, you need to clarify the title transfer node in the trade contract. If you use the FOB trade term, you need to ensure that the consignee information on the bill of lading is consistent with that on the customs declaration, to avoid title disputes.
At the same time, you need to add an abnormal disposal clause in the contract to clarify the bearer of losses caused by customs clearance delay. If losses such as port storage fees and breach penalties are caused by the agent's mistake, you can claim compensation according to the contract terms to protect your enterprise's legitimate rights and interests.

You need to make full preparations in advance for on-site customs inspection. For chemical raw materials, you need to ensure that the hazard marks on the cargo packaging are consistent with the MSDS report, to avoid inspection abnormalities triggered by inconsistent marks. During the inspection, you need to cooperate with customs officers to complete unpacking and sampling.
If customs requires third-party testing, you need to select a third-party testing institution recognized by customs to ensure the compliance of the test report. If the cargo has packaging damage or leakage, you need to submit the commodity inspection certificate in time and cooperate with customs to complete disposal, to avoid the cargo being returned or destroyed.

Packaging compliance of imported chemical raw materials is an important prerequisite for customs clearance. For solid chemical products such as modified resin, you need to use moisture-proof packaging that meets UN standards, to avoid moisture deterioration of the cargo during transportation. At the same time, clear commodity name, HS code, weight, origin and other information must be marked on the packaging, which is consistent with the customs declaration documents.
If the cargo is a hazardous chemical, you need to provide a performance inspection report for dangerous goods packaging to ensure the packaging meets transportation safety requirements. In addition, you need to place desiccants and buffer materials inside the packaging to reduce collision damage during transportation, and avoid customs clearance abnormalities caused by cargo damage.

If the modified resin you import is used for subsequent export business, you need to ensure that the information on import customs declaration documents is consistent with export tax rebate documents, including commodity name, HS code, quantity, weight, etc., to avoid affecting export tax rebate declaration due to inconsistent information. After import customs clearance is completed, you need to authenticate and deduct the import VAT special payment receipt in time.
If it is used for export, you need to submit the import customs declaration, payment receipt and other materials during tax rebate declaration to ensure consistency of contract, invoice, goods and fund; At the same time, you need to keep transportation and storage vouchers of imported goods to avoid being unable to provide relevant certificates during tax correspondence, which affects the tax rebate progress.

Import customs clearance needs to be coordinated with your enterprise's supply chain planning. For your chemical raw material import business, you can adopt the strategy of "advance declaration + inventory linkage", arrange cargo import in advance according to downstream customer order requirements, and use the customs advance declaration policy to shorten customs clearance time and ensure timely cargo warehousing.
At the same time, you can optimize trade terms by converting FOB to CIF, so that the supplier is responsible for transportation and insurance, reducing your enterprise's logistics risk. In addition, you can establish linkage between import customs clearance data and the inventory management system to track customs clearance progress and inventory level in real time, avoid stock shortage or overstock, and improve supply chain efficiency.
