Full Customs Clearance Process Breakdown: Practical Guide from Overseas Shipment to Domestic Clearance

Mr.Luo,purchasing manager of a Shanghai-based chain restaurant,decided to import a batch of fresh durian and mangosteen from Thailand at the end of last year.He was attracted by the price advantage of direct sourcing from the origin,but was unfamiliar with the series of procedures after the goods arrived at Shanghai Port.Fruits have a short shelf life,with strict import quarantine requirements.A slight deviation in customs code classification may delay clearance and cause full-container cargo damage.This is not an isolated case; many enterprises new to import business face similar challenges in the customs declaration process.

Foods imported from Southeast Asia,such as fresh produce,snack foods and seasonings,have seen strong domestic market demand in recent years.However,the common difficulties in importing these products fall into two aspects: first,complex access and quarantine requirements,which require advance confirmation of whether the products are on the allowed import list,and compliance with document requirements such as quarantine certificates and certificates of origin issued by the exporting country’s authorities; second,extreme sensitivity to clearance timeliness,with delays in any link directly leading to product spoilage and increased costs.At this point,the intervention of an experienced foreign trade agency becomes critical.Over the past 20 years of service,Zhongshen has handled numerous food import cases from Southeast Asia,Japan,South Korea,Europe and the United States.Its core role is to standardize and streamline the complicated and professional customs declaration process,and proactively address potential risks,ensuring that goods are cleared as quickly as possible while complying with all regulatory requirements.

Phased Practical Operations and Professional Handling of Import Customs Clearance

Import customs clearance is not an isolated action,but an interlocking process system.Taking imported food as an example,Zhongshen’s services usually cover the following key stages.

Pre-Shipment Preparation and Document Pre-Review

Work begins even before the goods are shipped.Mr.Luo needs to provide information such as invoices,packing lists and contracts from foreign suppliers.Zhongshen’s customs officers will first conduct a document pre-review,which is a critical step.They will accurately determine the corresponding customs commodity code based on the product description,which directly affects the applicable tariff rates,regulatory requirements and VAT rates.For example,pre-packaged snacks and bulk raw materials have different codes,tax rates and inspection standards.

For food products,customs officers will simultaneously review whether they comply with China’s national food safety standards,and confirm whether it is necessary to apply for "Registration of Overseas Food Production Enterprises" or "Registration of Import Food Importers".For Thai fruits,they will focus on checking whether the intended imported varieties are on the "List of Fresh Fruit Varieties and Exporting Countries/Regions Granted Quarantine Access by China".Last year,a customer planned to import a new type of Southeast Asian fruit.Zhongshen found during the pre-review stage that the variety had not yet obtained access,and immediately advised the customer to suspend shipment,avoiding significant losses such as goods being returned or destroyed due to quarantine issues upon arrival at the port.

• Verify basic trade documents such as pro forma invoices,packing lists and contracts provided by foreign parties.
• Accurately classify customs tariff codes based on product ingredients,processing technology and intended use.
• Check the corresponding regulatory requirements for the product,such as whether quarantine approval or import license is required.
• Confirm whether the importing enterprise has complete qualifications,such as whether the food importer registration has been completed.

Port Declaration and Inspection Cooperation

After the goods arrive at Shanghai Port or airport,the formal customs declaration process begins.Zhongshen’s customs officers will declare to the customs through the China International Trade "Single Window" based on the information confirmed in the pre-review.In addition to goods information,price and quantity,the declaration also needs to submit certificates of origin,health certificates / phytosanitary certificates (for food) and necessary license documents.

The customs system will decide whether to inspect the goods based on risk control instructions.If selected for inspection,the role of the agent becomes even more critical.They will notify the customer immediately and accompany customs officers for on-site inspection.For food,inspection may involve checking whether the goods match the documents,verifying whether the packaging labels comply with national standards,sampling for laboratory testing,etc.Zhongshen’s on-site staff are familiar with the inspection process and key points,can efficiently cooperate with customs work,and conduct professional communication on non-principle issues to avoid unnecessary delays in inspection time due to misunderstanding or insufficient preparation.

Different clearance methods have different focuses in terms of timeliness and cost,and enterprises can choose according to the characteristics and urgency of the goods.

Quarantine and Follow-up Management

For food,customs inspection and release does not mean the end of the process.The goods still need to receive follow-up supervision from market regulatory authorities,especially inspection and quarantine for imported food.Zhongshen will assist customers in archiving documents such as the "Entry-Exit Inspection and Quarantine Certificate" obtained after customs release,which is an important certificate for products to legally enter the domestic market for sale.In addition,they will remind customers to establish an imported food sales record system to ensure a complete product traceability chain in response to possible market inspections.

After completing all clearance procedures,agency services also extend to foreign exchange payment and tax links.Zhongshen can assist enterprises in making foreign exchange payments,ensuring that the payment amount is consistent with the declared amount and complies with foreign exchange regulatory requirements.For eligible import businesses,they can also provide relevant tax consulting.Throughout the process,customs officers will continue to track to ensure that the status of each shipment is clearly controllable.

Value of Professional Agents: Efficiency and Risk Management

Looking back at Mr.Luo’s case,under the full agency of Zhongshen,the customs declaration process for that batch of Thai fruits became clear and controllable.Customs officers reviewed the phytosanitary certificate and certificate of origin issued by the Thai authorities in advance,pre-classified the tariff code,and completed declaration preparations before the goods arrived at the port.Although the goods were selected for inspection after arrival,due to sufficient document preparation and smooth on-site cooperation,the inspection and release were completed in just one day,maximizing the freshness of the fruits.

This case reflects the core value of professional import agents.First,it is the improvement of efficiency.Agency companies are familiar with the connection and requirements of each link,can avoid delays caused by enterprises’ unfamiliarity with the process,and have smoother daily communication channels with terminals,customs and inspection yards.Second,and more importantly,it is the reduction of compliance risks.Customs regulations and quarantine standards are constantly updated,and one of the responsibilities of professional agents is to continuously track these changes.For example,at the end of 2025,China adjusted the standards for some food additives.Zhongshen immediately notified relevant import customers and assisted in reviewing the formula compliance of their subsequent imported products,avoiding the risk of goods being unable to enter the country due to non-compliance with the new standards upon arrival.

Import customs clearance is a rigorous professional work involving multiple regulatory departments such as customs,tax,foreign exchange and quarantine.Entrusting this work to a service provider with over 20 years of industry experience like Zhongshen,enterprises are not only purchasing a set of process services,but also a risk management mechanism and efficiency guarantee solution.It allows enterprises to focus more on market and sales,and leave the complicated customs clearance and compliance matters to trusted professional partners.
