Reliable sourcing and import agency services.
We are a trading company engaged in industrial sensor imports. The goods are shipped from Tokyo Port, Japan, and are expected to arrive at Shanghai Yangshan Port on June 12, 2026. Currently, we only hold the purchase contract, commercial invoice, ocean bill of lading and RCEP Certificate of Origin.
We have never formally handled import agency customs declaration and inspection before, and are worried about incurring port detention fees or even customs seizure due to incomplete documents or delays in process nodes. We would like to understand the complete operating process, as well as the cost optimization opportunities brought by the latest 2026 customs clearance policies, and hope to receive clear step-by-step guidance.

First，complete the online pre-review of pre-arrival documents. In 2026，customs has realized automatic verification of import documents for all categories. You can upload existing materials to the Single Window，and the system will quickly check document consistency. If any information deviation is found，it will prompt immediate modification，avoiding delays caused by subsequent document rejection.
Next，proceed to the core operation steps: First，Bill of Lading Exchange，exchange the ocean bill of lading for a delivery order from the shipping company. Note to confirm the shipping company's bill exchange time limit in advance to avoid occupying the free demurrage period，Second，Statutory Inspection，declaration must be completed 24 hours before the goods arrive at the port. For statutory inspection involving precision instruments，contact the commodity inspection agency in advance to arrange inspection，reducing on-site waiting time，Third，Customs Declaration，2026 supports pre-declaration 3 days in advance. You can submit customs declaration information for review ahead of time，and complete formal declaration directly after the goods arrive at the port，greatly shortening customs clearance duration.
If customs conducts machine-controlled inspection，arrange a dedicated person to cooperate with on-site unpacking，and provide supplementary materials such as goods technical parameters and warranty agreements. If a price assessment dispute arises，submit transaction price evidence to apply for consultation. In 2026，customs has launched an online price assessment consultation channel，which can greatly shorten the dispute handling cycle.
After paying taxes，collect the release notice，arrange pick-up and keep the full set of documents for filing. For goods eligible for RCEP preferential tariff rates，ensure the Certificate of Origin information matches the customs declaration form to enjoy tariff reduction or exemption. The core of the entire process is to conduct pre-review in advance，ensure smooth node connection，and leverage 2026 digital customs clearance tools to effectively reduce compliance risks and costs.

In 2026, the customs price assessment system has realized real-time linkage with global trade databases. If your imported goods have special transaction conditions, such as free warranty or after-sales support clauses, upload relevant supplementary agreements to the Single Window in advance. Otherwise, the system will automatically determine the transaction price is too low, triggering price assessment doubts.
If price assessment suspension occurs, you can apply for a temporary suspension period of up to 14 days. During this period, you do not need to pay the full tax amount, just submit a written explanation. If deletion and re-declaration is required, complete modifications within 3 working days after the system prompts document rejection, otherwise it will affect the enterprise's customs clearance credit rating.
In addition, the 2026 customs clearance integration policy covers all ports nationwide. You can choose to complete declaration at your Shanghai headquarters without submitting paper documents on-site at the port, greatly improving customs clearance efficiency.
If secondary declaration is needed, ensure the commodity code, price and quantity of the two declarations are completely consistent, otherwise it will be marked as abnormal declaration by the system, triggering a higher-level inspection.

In 2026, the free demurrage period of Shanghai Yangshan Port has been uniformly adjusted to 7 days, with a free detention period of 14 days. You need to complete bill exchange and inspection within 7 days after the goods arrive at the port, otherwise port detention fees will be incurred, amounting to approximately RMB 150 per container per day.
If you choose a direct route, the transit time from Tokyo to Shanghai is about 3 days, saving 2 days compared with transit routes, effectively shortening the occupation of the free demurrage period.
If your goods are dangerous goods, declare the dangerous goods manifest to the shipping company 7 days in advance and arrange a dedicated dangerous goods yard, otherwise the shipping company will refuse to release the goods. In addition, bill of lading endorsement transfer must be completed before bill exchange.
If the bill of lading is an order bill of lading, it must be endorsed with the shipper's official seal, otherwise the bill exchange procedure cannot be completed. In 2026, the logistics platform has realized online sharing of bill of lading information. You can directly check the bill of lading status on the platform without contacting the shipping company for manual inquiry.

In 2026, the VAT Deferral policy covers all general trade imported goods. You can apply for deferred payment of import VAT, which can be paid later when the goods are sold, optimizing the enterprise's cash flow.
However, note that the deferred VAT must be paid within the declaration period of the next month after sale, otherwise late payment penalties will be incurred. In addition, if your enterprise is a cross-border e-commerce import pilot enterprise, you can enjoy a lower import VAT rate, but need to register with customs in advance.
If related-party transaction imports are involved, ensure pricing complies with BEPS Rules. In 2026, tax authorities will conduct key inspections on the import prices of related-party transactions.
If pricing is significantly lower than the market price, you will be required to adjust and pay supplementary taxes. You can prepare related-party transaction pricing documents in advance for inspection by customs and tax authorities.

In 2026, the CIPS System supports full-currency cross-border payments. You can choose to settle import payments in RMB to avoid exchange rate losses. Meanwhile, the system will automatically compare the payment/receipt amount with the customs declaration amount.
If the difference exceeds 5%, a regulatory alert will be triggered. You must ensure the purpose of payment/receipt matches the trade method on the customs declaration form. For example, payment for imported goods must be marked as "General Trade Import Payment", otherwise it will be deemed illegal payment/receipt.
In addition, the SWIFT Message must contain complete trade information, including commodity name, quantity, amount, etc. If the message information is inconsistent with the customs declaration form, it will be returned by the bank, delaying payment/receipt efficiency. You can use the SWIFT Message automatic verification tool launched in 2026 to check message compliance in advance and avoid errors.

The responsibility division for customs declaration and inspection must be clearly specified in the import contract. If you entrust an agency company to handle customs declaration and inspection, agree on the agency's scope of responsibilities in the contract.
For example, if the agency's mistake leads to non-compliant documents and customs seizure, the agency shall bear corresponding losses. Meanwhile, if goods have quality issues, agree on the return process and responsibilities in the contract. A bank guarantee can be used as return security to avoid cargo ownership disputes.
In 2026, the Customs Protection Record of Intellectual Property system has realized online registration. You can register the enterprise's trademarks, patents and other intellectual property rights in advance.
If imported goods infringe your intellectual property rights, customs will directly seize the goods and notify you. In addition, if letter of credit transactions are involved, ensure the letter of credit terms match the contract to avoid soft clauses that prevent smooth settlement.

In 2026, the accuracy of customs machine inspection has reached over 95%. If your goods packaging complies with UN Standards, the machine inspection speed will be 30% faster than ordinary packaging.
If unpacking inspection is required, prepare materials such as MSDS, technical parameters and packing list in advance to cooperate with customs unpacking. If seals are found damaged, notify the shipping company and customs immediately to avoid cargo ownership disputes.
If customs requires inspection, send samples to the designated commodity inspection agency. The inspection cycle is about 3-5 days, so you need to reserve sufficient time in advance.
In addition, the online inspection appointment system launched in 2026 allows you to book inspection time in advance, avoiding long waits at the port. If the inspection result is unqualified, complete rectification and re-submit the inspection application within 7 days, otherwise the goods will be returned.

If your goods are precision sensors, use moisture-proof and shock-absorbing packaging, such as wrapping with EPE foam and desiccants, to ensure packaging strength meets ocean transportation requirements.
Meanwhile, prepare the MSDS (Material Safety Data Sheet) and mark correct labels on the packaging, such as fragile or moisture-proof labels. If the goods are dangerous goods, pack them in accordance with the IMDG Code and obtain the Dangerous Goods Packaging Appraisal Certificate.
In 2026, the online packaging compliance review system has been launched. You can upload the packaging plan to the system, which will automatically review whether it meets international transportation standards.
If issues are found, it will prompt immediate modification. In addition, if your goods require long-distance transportation, use vacuum packaging for moisture-proof treatment to avoid damage from moisture during transportation.

In 2026, the digital supply chain platform has realized full-linkage of customs declaration, logistics and taxation. You can view the goods' customs clearance status, logistics track and tax payment status in real time through the platform, plan inventory in advance, and optimize supply chain efficiency.
In addition, you can choose to use the DAP Incoterm to transport goods to the designated destination, with the seller bearing transportation and insurance costs, reducing the buyer's logistics risks.
You can use the supply chain planning model to calculate customs clearance costs for different ports. For example, Shanghai Yangshan Port has high customs clearance efficiency but relatively high costs, while Ningbo Zhoushan Port has lower costs but slightly slower clearance time.
You can choose the appropriate port based on the goods' urgency. In addition, you can optimize trade term selection, such as using CIF instead of FOB, with the seller responsible for arranging transportation and insurance, reducing the buyer's logistics pressure.
