Full Process of Import Customs Declaration Agency Services, Solutions for Compliance Clearance, Customs Valuation and Commodity Inspection Issues

Customs Valuation: Predict Compliance Risks in Advance

I previously worked with Mr.Chang from Zhejiang,who imported a batch of general cargo from Thailand,an RCEP member state.When he filed the declaration on his own,the issue date of the certificate of origin did not match the shipment date on the bill of lading,which triggered customs valuation consultation.The customs authority questioned the authenticity of the transaction price,and he almost paid an extra 120,000 yuan in additional tariffs.

In 2026,customs authorities will launch a new generation of big data-based customs valuation model,which no longer only refers to the price range of identical goods,but conducts multi-dimensional comparison combining FOB transaction price,domestic selling price in the exporting country,foreign exchange payment data,and logistics costs.Any document discrepancy will trigger manual review.The core value of professional import customs declaration agency services is to complete all data verification before declaration,and prepare supporting documents for transaction prices in advance,such as foreign exchange payment slips,trade contracts,and original factory invoices,to avoid customs valuation disputes.

Accurate HS Code Classification is the foundation of customs valuation.Incorrect classification will not only lead to miscalculation of tax rates,but also directly trigger targeted inspection.We arrange two rounds of review in our operations: one to check the actual product specifications when receiving the order,and another to cross-check with the latest customs code catalog before declaration,ensuring a classification accuracy rate of over 99%.

Commodity Inspection Pre-review and Animal and Plant Quarantine Requirements

Pre-screening to Avoid Customs Detention Risks

Different categories of imported goods are subject to different quarantine requirements.General cargo requires commodity inspection pre-review,wooden packaging requires IPPC mark verification,and animal and plant-derived products require entry quarantine approval.Many cargo owners easily overlook the marking requirements for wooden packaging.Wooden packaging without an IPPC mark must be destroyed after arrival at the port,resulting in costs far higher than the value of the goods themselves.

I previously met Mr.Fan from Beijing,who imported a batch of instruments.The wooden packaging did not have the IPPC mark,so the goods were detained after arriving at Shanghai Port.He had to destroy the packaging,and with the demurrage charges,he spent a total of more than 30,000 yuan in extra costs,which could have been completely avoided in advance.After receiving the order,we will check the packaging requirements as soon as possible,and remind foreign shippers to mark the packaging in accordance with the requirements of Chinese customs to avoid problems after arrival at the port.

Key Points for Import License Processing

For imports of controlled products,such as used electromechanical equipment,endangered species products,food and cosmetics,import licenses must be applied for in advance.Many cargo owners do not know the application process,and only start processing after the goods arrive at the port,resulting in a large amount of demurrage charges.I previously met Manager Tang from Dongguan,who imported a used CNC machining center.He did not apply for the electromechanical product import license and pre-shipment inspection (CCIC) in advance,so the goods were detained after arriving at Shenzhen Port,stayed at the port for 14 days,and incurred more than 90,000 yuan in demurrage charges.Finally,he contacted us to coordinate and handle the supplementary pre-shipment CCIC inspection,and the goods were cleared smoothly.

The core of import customs declaration agency services is to resolve all problems in advance.After signing the contract,we will check the product supervision conditions as soon as possible.For products requiring import licenses,we will organize all required materials in advance and follow up the application progress to ensure that the license is obtained before the goods arrive at the port,without delaying customs clearance.

Key Pitfall Avoidance Points for Import Customs Declaration Agency

• In 2026,the fine range for incorrect HS code classification by customs authorities has increased by 15%.The declared elements including brand,model,material and specification must be completely consistent with the actual goods.Missing declaration will lead to direct detention of the declaration form.
• The standards for document exchange fees and terminal handling charges must be confirmed in advance.Some intermediaries will increase the price by 30%-50%.All fees must be listed clearly in advance to avoid hidden charges later.
• For imported goods under the RCEP framework,it is necessary to verify that the country of origin standard on the certificate of origin and the shipping mark are consistent with the goods.Otherwise,the preferential tariff cannot be enjoyed,resulting in unnecessary extra tax payment.
• Under-declaration of price and false declaration of product name are absolute compliance red lines.In 2026,the data of customs authorities and the foreign exchange administration are fully interconnected.Violations will affect the import and export credit of enterprises,with serious consequences.
