I am the procurement director of a stone processing factory in Shanghai. Last month, I ordered 2 containers of premium beige marble blocks from Carrara, Italy, and the goods have been at Yangshan Port for 3 days. The small agent I contacted earlier said customs clearance would take at least 10 days, but a peer I cooperated with last year said they only spent 5 days with a large agent.

This batch of materials is used for the fine decoration project of a high-end hotel in the city center with a very tight schedule, and I have to pay 80,000 yuan in liquidated damages to the owner for each day of delay. I now check the port information every day and am too anxious to sleep well.

I would like to ask you, what is the normal duration of agent-assisted marble import customs clearance? Which links are the core cause of time difference under different circumstances? Is there any compliant expedited channel? Will there be additional delays due to inspection or document problems?

The duration control of marble import customs clearance requires precise efforts from all nodes of the full link. First,for the pre-document pre-audit link,double review of the full set of documents shall be completed 7-10 days before the arrival of the goods,including certificate of origin,bill of lading,packing list,invoice,stone radioactivity test report,etc. Special attention shall be paid to consistency of information on the certificate of origin to avoid delay in document modification caused by inconsistency between the certificate of origin and the bill of lading in product name and quantity,which is the core premise for reducing overall time consumption.

Under normal circumstances,the full-link duration of marble import customs clearance with correct documents is 3-5 working days: bill of lading exchange and inspection declaration pre-entry are completed on the day of arrival,customs declaration application is submitted the next day and inspection appointment is synchronized (if no inspection is required),the customs completes value assessment and tax collection on the third day (pre-filed free trade agreement certificate of origin can directly enjoy tariff reduction without additional review),container pick-up can be arranged after customs release on the fourth day,and domestic distribution is completed on the fifth day. Core nodes shall realize "seamless connection",that is,inspection declaration information shall be synchronized immediately after bill of lading exchange to avoid time gap caused by waiting.

Exclusive contingency plans shall be prepared in advance for abnormal situations: in case of customs inspection (the inspection probability of marble blocks is about 15%),samples,test reports and other materials shall be prepared in advance to cooperate with on-site verification. Generally,X-ray inspection takes 1 working day,and manual unpacking inspection takes 2 working days,if value assessment dispute is triggered,supporting materials such as procurement contract and foreign exchange payment voucher shall be submitted within 24 hours,and we will carry out pre-communication with the local customs synchronously to reduce value assessment time to less than 3 working days.

In the final compliance implementation link,document archiving shall be completed synchronously to ensure that materials such as radioactivity test reports meet domestic environmental protection requirements and avoid subsequent traceability risks. In addition,the VAT deferral mode can simplify the tax payment process,directly cut the tax payment waiting time by 1-2 working days,and further optimize the overall efficiency.

The duration of marble import customs clearance is directly related to the value assessment link. If the declared price deviates from the guide price of the customs system by more than 10%, the value assessment dispute process will be triggered, and the time will be extended from 1 working day to 3-5 working days. Note that the value assessment basis for marble includes international stone market quotation, authenticity of procurement contract, consistency of foreign exchange payment vouchers, etc. If the provided supporting materials are incomplete, secondary value assessment may be triggered, leading to further delay.

In addition, if there is an error in customs code classification, for example, marble blocks are mistakenly classified as stone products, it will lead to document deletion and re-declaration, increasing the time by 5-7 working days. It is necessary to ensure the accuracy of the customs code and apply for classification pre-ruling with the local customs in advance to avoid such problems.

The duration of marble import customs clearance is also related to the end connection of international logistics. If a direct ship to Yangshan Port is selected, cargo backlog at the transshipment port can be avoided, and bill of lading exchange can be carried out immediately after arrival; if a transshipment ship is selected, an additional 2-3 working days of transshipment connection time is required. In addition, rational use of the free storage period is also very important. The free storage period of Yangshan Port is 7 days.

If the customs clearance time exceeds the free storage period, port demurrage will be incurred, which is about 200-300 yuan per container per day. It is necessary to confirm the ship arrival time with the logistics agent in advance, and arrange the connection between bill of lading exchange and customs clearance to avoid waste of free storage period caused by ship schedule delay. At the same time, the "advance declaration" mode can be selected to complete customs declaration pre-entry 3 days before the arrival of the goods, and release immediately after arrival, reducing the time by 1-2 working days.

The duration of marble import customs clearance is directly related to the efficiency of the tax payment link. If the traditional offline tax payment method is adopted, it takes 1-2 working days to complete tax payment and customs confirmation; if VAT deferral is adopted, that is, there is no need to pay value-added tax immediately at the time of import, and declare for deduction when subsequent domestic sales are made, the tax payment process time can be reduced by 1-2 working days.

In addition, if the marble comes from a country that has signed a free trade agreement with China, it is necessary to complete electronic filing of the certificate of origin in advance to ensure rapid review of tariff reduction, and avoid value assessment delay caused by untimely filing. Note that VAT deferral is only applicable to general taxpayer enterprises, and must meet the compliance requirements of the customs to avoid process return caused by unqualified qualifications.

The duration of marble import customs clearance is related to the compliance of foreign exchange receipt and payment. If the foreign exchange payment voucher is inconsistent with the information of the procurement contract and invoice, customs compliance verification will be triggered, increasing the time by 2-3 working days. It is necessary to ensure that the postscript of the SWIFT message clearly indicates "marble block procurement payment", and the deviation between the foreign exchange payment amount and the invoice amount does not exceed 5%, so as to avoid verification caused by inconsistency of foreign exchange receipt and payment.

In addition, if RMB cross-border payment (CIPS) is adopted, the arrival time of foreign exchange payment can be shortened, the timeliness of supporting materials can be ensured, and the customs clearance time can be further reduced. It is necessary to confirm the compliance requirements for foreign exchange payment with the bank in advance to avoid customs clearance block problem caused by delay in the foreign exchange payment process.

The time consumption of marble import customs clearance in case of inspection mainly depends on the type of inspection. If it is X-ray inspection, it takes about 1 working day; if it is manual unpacking inspection, it takes about 2 working days. It is necessary to prepare labels, test reports and other materials for marble blocks in advance to avoid inspection delay caused by incomplete materials.

In addition, if the radioactivity test results of marble do not meet domestic standards, they will be detained by the customs, increasing the inspection and rectification time by 7-14 working days. It is necessary to complete the radioactivity test in the exporting country in advance and ensure that the validity period of the report is still valid at the time of import, so as to avoid inspection delay caused by expired test reports.

The duration of marble import customs clearance can be optimized through pre-planning of the supply chain. For example, the "door-to-door" full-link agency mode is adopted to integrate international logistics, customs clearance and domestic distribution links to avoid connection delays between different agents.

In addition, according to the schedule requirements of the project, arrange the shipment of goods 15-20 days in advance, reserve buffer time for abnormal customs clearance, and avoid project delay caused by customs clearance delay. At the same time, an inventory linkage strategy for marble import can be established, and goods import can be arranged in advance according to the progress of the project to ensure that the goods can be put into use immediately after customs clearance, so as to further improve the efficiency of the supply chain.

The duration of marble import customs clearance is related to the clause agreement of the trade contract. If the submission time and format of documents are not clearly agreed in the contract, the exporter will delay providing documents, which will affect the customs clearance duration.

It is necessary to clearly agree in the trade contract the submission time (within 3 days after the goods are shipped) and format requirements (in line with the specifications of Chinese customs) of documents such as certificate of origin and test report, and agree on the liability for breach of contract for delayed submission, so as to avoid customs clearance delay caused by the delay of the exporter. In addition, if L/C payment is involved, soft clauses in the L/C shall be avoided, such as "documents shall be submitted after the buyer confirms the samples", which will lead to delay in document submission and thus affect the customs clearance duration.
