# Are there professional companies in Zhongshan that provide full-process compliant import customs brokerage services?

## Question

 I am the procurement director of a precision instrument manufacturing enterprise in Zhongshan. Last week, we air-freighted a batch of core lithography machine components from Germany. The small customs brokerage firm we cooperated with before caused the goods to be detained at the port for 3 days due to document review omissions, which not only incurred nearly 20,000 yuan in demurrage fees, but also delayed the urgent maintenance of the production line, resulting in a 100,000 yuan penalty paid to the factory. I still feel frightened when I recall this experience. We will import another batch of high-value components of the same type next month, so I would like to ask if there are professional import customs brokerage companies in Zhongshan that can strictly control document review, handle abnormal situations, and carry out tax compliance planning to reduce costs for us? 

## Answers
                            
### Answer 1 — Best Answer

For the import of precision instrument components，first of all，the **pre-document review details** shall be properly handled: check the consistency of the certificate of origin，original factory invoice，packing list，3C certification (if required) and instrument manual 7-10 days in advance，focus on verifying the matching degree of component models and serial numbers in the invoice with those on the customs declaration form，to avoid targeted inspection caused by inconsistent documents.

Seamless connection of core nodes shall be realized: for air freight transshipment，pre-declare manifest information to Zhongshan Customs 1 day in advance，and simultaneously coordinate with the airport freight station to arrange container pickup，to ensure real-time synchronization between manifest information and customs declaration data，and avoid port detention caused by information gap. Meanwhile，communicate with the on-site customs inspection department in advance about the high-precision attribute of the goods，and apply for priority inspection channel to reduce the risk of goods damage caused by unpacking.

Emergency plans shall cover all scenarios: if targeted inspection is triggered，immediately start the backup document recheck process，arrange professional personnel to accompany the inspection on site，and issue original factory technical descriptions to prove the goods attributes，in case of tariff code classification disputes，submit classification pre-ruling application within 3 hours to avoid long-term port detention of goods.

At the final compliance implementation stage，the **VAT deferral declaration** and foreign exchange payment compliance filing shall be completed simultaneously，handle goods pickup procedures in time with the customs release form，and archive all documents for more than 5 years to meet the post-inspection requirements of Zhongshan Customs.

### Answer 2

For price review disputes in import customs declaration, supporting materials such as original factory purchase and sales contracts, foreign exchange payment slips, and import customs declaration records of the same model products in the past 3 months shall be submitted to the customs in advance. If the customs initiates a price query, submit a price negotiation application within 5 working days to avoid customs seizure caused by failed price review.

At the same time, pay attention to the price review standard for high-value precision instruments of Zhongshan Customs, and ensure that the deviation between the invoice amount and the market fair value does not exceed 10%, otherwise the secondary price review process will be triggered. In addition, if it involves deleting and re-submitting the declaration form, check the consistency between manifest information and customs declaration form in advance to avoid manifest information locking caused by declaration deletion, which affects subsequent goods pickup.

### Answer 3

For the import logistics of precision instruments, choose direct flights to Zhongshan Port to avoid cargo right risks in the transshipment link, and apply for priority loading and unloading permission for the goods from the airline in advance to reduce container storage time at the airport.

In case of container rolling, immediately start the standby space plan, contact the airline to arrange transshipment for subsequent flights, and apply for demurrage fee reduction procedures to the customs at the same time, provide proof materials for urgent goods maintenance to obtain policy support from the customs. In addition, pay attention to the authenticity identification of container seals, check the consistency between the seal number and the bill of lading record on site when picking up containers, to avoid goods being swapped during transportation.

### Answer 4

For VAT deferral declaration of imported goods, the access conditions of Zhongshan Customs shall be met: the enterprise shall have general taxpayer qualification, and the imported goods are used for production and operation activities. At the same time, the VAT deferral application form shall be submitted when declaring, to ensure that the "taxation method" column in the customs declaration form is checked as "VAT deferral".

In addition, the deferred tax declaration shall be completed within the VAT declaration period of the next month to avoid late fees caused by overdue declaration. At the same time, pay attention to the applicable scope of VAT deferral, sensitive categories such as chemicals and food are not applicable temporarily, and verify the category access qualification with the tax department in advance.

### Answer 5

For the compliant operation of import foreign exchange payment, check the consistency of the customs declaration form, bill of lading and invoice before foreign exchange payment, to ensure that the deviation between the foreign exchange payment amount and the dutiable value of the customs declaration form does not exceed 5%, so as to avoid verification triggered by abnormal foreign exchange payment from the State Administration of Foreign Exchange.

If cross-border RMB payment is involved, submit the foreign exchange payment application through the CIPS system, and archive all foreign exchange payment vouchers for more than 5 years to meet the post-inspection requirements of the State Administration of Foreign Exchange. In addition, pay attention to the use specification of offshore accounts, and prohibit foreign exchange payment operations without real trade background through offshore accounts to avoid account freezing.

### Answer 6

For the cargo right transfer of imported goods, the time node of cargo right transfer shall be clearly specified in the purchase and sales contract. If FOB trade term is adopted, the cargo right is transferred when the goods are loaded on board; if CIF term is adopted, the cargo right is transferred when the goods arrive at the destination port.

At the same time, check the identity information of the endorser when endorsing the bill of lading, to ensure that the endorser is consistent with the buyer in the purchase and sales contract, and avoid cargo right disputes caused by wrong endorsement. In addition, if goods delay is caused by force majeure, the scope of force majeure shall be clearly specified in the contract, and relevant supporting materials shall be kept to avoid compensation disputes caused by breach of contract.

### Answer 7

For the on-site inspection of precision instruments, submit the precision attribute description of the goods to the customs in advance, and apply for the accompaniment of enterprise technical personnel during unpacking inspection, so as to avoid goods damage caused by the operation of customs personnel. If abnormal machine inspection is triggered, immediately submit the original factory technical drawings of the goods to prove that the internal structure of the goods is consistent with the description in the customs declaration form, and avoid customs seizure caused by abnormal machine inspection.

In addition, pay attention to the interpretation of the inspection notice. If "testing required" is indicated in the notice, contact the inspection institution designated by the customs to complete the testing within 3 working days, so as to avoid demurrage fees caused by overdue testing.

### Answer 8

For the import packaging of precision instruments, buffer packaging materials that meet international standards, such as foam plastics and air cushion films, shall be used to ensure that the goods are not damaged by vibration during transportation. At the same time, a detailed MSDS report shall be prepared.

If the goods involve sensitive materials, submit the material test report to the customs in advance to ensure compliance with the packaging compliance requirements of Zhongshan Customs. In addition, pay attention to the moisture-proof treatment of the container, place desiccant inside the container to avoid moisture damage to the goods during transportation, and indicate the moisture-proof grade of the packaging in the packing list to ensure the consistency between the customs declaration form and the packing list.

### Answer 9

For the import supply chain planning of precision instruments, adopt the JIT (Just-in-Time) procurement mode, arrange the transportation and customs declaration process of the goods 15-20 days in advance to ensure that the goods arrive at the factory 1 day before the production line maintenance. At the same time, establish an inventory linkage strategy, adjust the quantity and time of imported goods according to the maintenance plan of the production line, to avoid capital occupation caused by overstock.

In addition, pay attention to the conversion of trade terms. If converting from FOB to CIF, calculate the cost of freight and insurance premium in advance to ensure the controllability of total cost, and negotiate the trade term conversion conditions with the supplier at the same time to avoid disputes caused by trade term conversion.
