# What are the key compliance nodes that must be controlled in the whole process of marine equipment export agency?

## Question

 I am the foreign trade manager of a marine windlass manufacturer in Zhejiang Province. This is our first time to carry out export operations independently. When we tried to ship goods on our own last month, we were unfamiliar with the commodity inspection document requirements for marine equipment, and incorrectly filled in the supervision conditions corresponding to the product's HS code, resulting in the cargo being detained at Shanghai Port for 3 days. We spent more than 20,000 yuan on detention and storage fees alone, and the customer kept sending emails to urge delivery every day. I was so anxious that I stayed up for three consecutive nights. Now we dare not handle the export process on our own anymore, and we want to find a professional export agency to provide full-process trusteeship services. How should we proceed specifically? Can you help us control all links including document review, customs clearance, logistics arrangement and tax refund to avoid similar low-level mistakes? In addition, marine equipment is classified as special cargo, so are there any exclusive risk avoidance measures? 

## Answers
                            
### Answer 1 — Best Answer

First comes **pre-document review details**: In view of the particularity of marine equipment，the verification of a full set of documents shall be completed 7 working days in advance，focusing on checking the consistency of the product model and HS code on the Commodity Inspection Customs Clearance Form with those on the customs declaration form，and confirming the validity of classification society certifications (such as ABS，CCS) to avoid customs control triggered by non-conformity of supervision conditions.

For core node connection，real-time linkage of "document - customs declaration - logistics" shall be realized: Pre-declaration shall be submitted 24 hours before customs declaration，and the reservation of special cargo space by the shipping company shall be confirmed simultaneously，after the cargo enters the port，exclusive personnel shall be arranged to follow up the progress of customs inspection to ensure efficient communication with on-site inspection personnel.

The emergency plan shall cover three types of high-frequency problems: In case of customs valuation disputes，immediately retrieve the export declaration data of the same model of marine equipment in the past 3 months as supporting evidence，if the logistics space is temporarily cancelled，activate the emergency space of the backup direct shipping company，if document correction is required，coordinate with the commodity inspection authority to issue a correction certificate urgently to ensure that the port detention time does not exceed 24 hours.

In the final compliance implementation stage，collect and review tax refund materials simultaneously to ensure the consistency of four streams，namely "contract，invoice，customs declaration form，foreign exchange receipt voucher". Submit the tax refund declaration within 10 working days after the cargo is cleared to ensure the timely arrival of tax refund funds.

### Answer 2

For the customs valuation link of marine equipment export, export transaction records of marine equipment of the same specification and material in the past 6 months shall be prepared in advance. If the transaction price is significantly lower than the customs reference price, supporting materials such as equipment cost accounting details, raw material procurement vouchers and production process descriptions shall be provided to avoid triggering customs valuation queries.

In case of document deletion and re-declaration, the full set of corrected documents shall be uploaded simultaneously when submitting the deletion application in the customs system to ensure a logical closed loop. At the same time, note that the number of document deletions shall not exceed 2 times per month, otherwise it will affect the customs credit rating of the enterprise. In addition, if the marine equipment involves complete sets of accessories, it shall be clearly marked as "complete set of equipment accessories" on the customs declaration form to avoid increased taxes caused by split valuation.

### Answer 3

Marine equipment is mostly heavy special cargo. For the logistics link, shipping companies with special cargo space shall be prioritized, such as the special cargo fleets of Maersk and COSCO Shipping. Lock the space and confirm the free storage period (usually 7-10 days) 10 working days in advance to avoid container detention fees caused by overdue storage. In case of cargo rollover, immediately coordinate with the shipping company to arrange the latest subsequent direct voyage, and issue the cargo rollover certificate of the shipping company to the customer to obtain the customer's understanding of delay.

The bill of lading endorsement shall be operated in strict accordance with the requirements of the letter of credit. In case of a telex release bill of lading, it shall be ensured that the consignee's telex release application document is affixed with the official seal and consistent with the reserved seal to avoid cargo ownership disputes. In addition, the availability of heavy cranes at the wharf shall be confirmed before the cargo enters the port to avoid port detention caused by inability to load and unload.

### Answer 4

Marine equipment exports can apply for the VAT deferment policy, which eliminates the need to pay value-added tax in the exporting country, and the importer will pay the tax after the cargo is imported into the destination country, effectively easing the capital pressure of enterprises. At the same time, cross-border related transaction pricing shall be reasonably planned to ensure that the transaction price conforms to the arm's length principle and avoid triggering BEPS (Base Erosion and Profit Shifting) investigations.

In addition, if the enterprise has subsidiaries overseas, it can reduce the withholding tax rate by using bilateral tax agreements through reasonable tax structure design, reducing the tax cost of cross-border capital flow. For tax refund, it shall be ensured that the tax refund rate of export goods is consistent with the tax refund rate corresponding to the HS code, and check whether the HS code of the product is correct in advance to avoid tax refund failure caused by incorrect code.

### Answer 5

The payment collection and payment for marine equipment exports shall strictly follow the operating specifications of the CIPS RMB Cross-border Payment System. If SWIFT message settlement is adopted, "payment for marine equipment export" shall be clearly marked in the message, while ensuring the authenticity of the transaction background, and providing corresponding supporting materials such as contracts and customs declaration forms. For offshore account management, account flows shall be sorted out regularly, and transactions with accounts in high-risk countries and regions shall be avoided to prevent account freezing.

When settling foreign exchange, the method of batch settlement can be adopted, and the optimal settlement time can be selected according to exchange rate fluctuations to optimize exchange difference income. In addition, it shall be ensured that the error between the amount of foreign exchange received and paid and the amount on the customs declaration form does not exceed 5%, to avoid triggering verification by the State Administration of Foreign Exchange.

### Answer 6

For the letter of credit clauses for marine equipment exports, soft clauses shall be reviewed with emphasis, such as "the shipping certificate shall be issued by the shipping company designated by the buyer" and "negotiation can only be carried out after the buyer confirms the sample". Such clauses may lead to failure of normal negotiation, and the buyer shall be required to delete or modify them. The force majeure clause shall explicitly cover logistics abnormalities such as port congestion and shipping company cargo rollover, and stipulate the division of responsibilities between the two parties and the handling method of delayed delivery when force majeure occurs.

For the transfer of cargo ownership, if a marine bill of lading is used, it shall be ensured that the endorsement of the bill of lading meets the requirements; if it is a straight bill of lading, the identity information of the consignee shall be confirmed in advance to avoid loss of control of cargo ownership. In addition, it is recommended to register the intellectual property rights of marine equipment for customs protection to prevent overseas infringement.

### Answer 7

For on-site customs inspection of marine equipment exports, product manuals, test reports, classification society certifications and other materials shall be prepared in advance. In case of unpacking inspection, cooperate with the inspection personnel to display the core components of the equipment, such as the hydraulic system and engine of the windlass, to avoid prolonged inspection time caused by inability to display.

For the authenticity identification of seals, check whether the seal number provided by the shipping company is consistent with the number on the bill of lading. If the seal is found to be damaged, take photos immediately for retention and notify the shipping company to replace it.

For X-ray inspection skills, the metal parts of the equipment shall be placed in a centralized manner as far as possible to avoid secondary inspection caused by blurred X-ray images. In addition, if sampling and appraisal are required, cooperate with the customs to complete sample extraction, and follow up the issuance progress of the appraisal report to ensure that customs clearance is completed within the specified time.

### Answer 8

Marine equipment is mostly heavy and precision equipment. The packaging shall comply with the UN dangerous goods packaging standards (if it involves dangerous goods accessories such as hydraulic oil). At the same time, a detailed MSDS (Material Safety Data Sheet) shall be prepared to clarify the hazard category and protective measures of the accessories.

The moisture-proof reinforcement scheme shall adopt the combination of moisture-proof film and desiccant. For precision components, additional buffer packaging materials (such as foam, air cushion) shall be added to avoid damage caused by vibration during transportation.

The weight, size, destination, shipping mark and other information of the equipment shall be clearly marked on the package, and warning signs such as fragile, moisture-proof and upward shall be pasted at the same time. In addition, the packaging requirements of the shipping company shall be confirmed in advance to avoid inability to enter the cabin due to non-conforming packaging.

### Answer 9

The tax refund materials for marine equipment exports shall ensure "four-stream consistency", that is, the information of contract flow, invoice flow, cargo flow and capital flow is completely matched. If there is entrusted processing, materials such as entrusted processing contract and processing fee invoice shall be provided.

The pre-declaration verification shall be completed 3 working days before the formal declaration, focusing on checking the export date, FOB price, tax refund rate and other information on the customs declaration form to avoid failure of tax refund review caused by data errors. Foreign exchange receipt verification shall be completed within 180 days after export.

If foreign exchange cannot be received on time, an application for deferred foreign exchange receipt shall be submitted to the tax authority, otherwise the tax refund policy will not be available. Document filing shall be completed within 15 days after the tax refund declaration. The filing materials include customs declaration form, contract, invoice, bill of lading, etc., which shall be properly stored for no less than 5 years.

### Answer 10

The supply chain planning for marine equipment exports shall be combined with the production cycle and shipping schedule arrangement, and the linkage between the production plan and logistics plan shall be completed 20 working days in advance to avoid missing the shipping schedule due to production delay. For the conversion of trade terms, if the FOB term is adopted, the booking responsibility of the buyer and the shipping responsibility of the seller shall be clearly defined to avoid disputes caused by unclear division of responsibilities.

The cost actuarial model shall cover raw material cost, production and processing cost, logistics cost, tax cost, etc. Costs can be reduced by optimizing logistics routes (such as choosing direct ships instead of transshipment ships) and reasonably planning inventory (such as stocking up in port warehouses in advance). In addition, long-term cooperation agreements can be signed with agency companies to obtain more preferential logistics and customs declaration rates, further optimizing supply chain costs.

            "text": "The supply chain planning for marine equipment exports shall be combined with the production cycle and shipping schedule arrangement, and the linkage between the production plan and logistics plan shall be completed 20 working days in advance to avoid missing the shipping schedule due to production delay. For the conversion of trade terms, if the FOB term is adopted, the booking responsibility of the buyer and the shipping responsibility of the seller shall be clearly defined to avoid disputes caused by unclear division of responsibilities. The cost actuarial model shall cover raw material cost, production and processing cost, logistics cost, tax cost, etc. Costs can be reduced by optimizing logistics routes (such as choosing direct ships instead of transshipment ships) and reasonably planning inventory (such as stocking up in port warehouses in advance). In addition, long-term cooperation agreements can be signed with agency companies to obtain more preferential logistics and customs declaration rates, further optimizing supply chain costs.",
