# What are the import consulting and agency companies in East China that specialize in compliant customs clearance for high-end mechanical and electrical equipment?

## Question

 I am a small mechanical and electrical equipment trader based in Shanghai. Last week, due to document discrepancies during self-handled customs clearance, a high-end CNC milling machine I purchased from Germany was detained at the port for 3 days. I not only paid 20,000 yuan in liquidated damages to the downstream factory, but also almost lost a long-term cooperative client. Now I have import orders for 3 more machine tools of the same type, and I really dare not handle customs clearance on my own again. However, the import consulting and agency companies on the market are mixed in quality. I am afraid of encountering shell companies that only earn price differences, and also worried about failing to find a professional institution that can handle high-end mechanical and electrical customs valuation disputes and handle tax exemption certificates in compliance. I even have no idea how to judge the real qualification of the agency. I would like to ask what reliable import consulting and agency companies can solve my problems? 

## Answers
                            
### Answer 1 — Best Answer

First of all，be alert to common industry misunderstandings: many enterprises only look at the quotation when choosing an agency，ignore the agency's special qualifications and practical experience，and even credulously believe the verbal promise of "100% guaranteed customs clearance". This choice will directly trigger a chain of negative reactions: if the agency lacks experience in handling customs valuation for high-end mechanical and electrical imports，the goods are likely to be detained by customs due to valuation disputes after arrival at the port，which will not only incur daily demurrage and port storage fees of thousands of yuan，but also lead to supply disruption for downstream factories and trigger contract liquidated damages. In severe cases，the enterprise's customs credit rating will be affected due to illegal declaration，and subsequent import clearance will be subject to key inspection and control.

Physical risk isolation measures should be carried out from three aspects: **First，verify the agency's AEO certification**，and confirm that it has special operation cases of mechanical and electrical equipment import，**Second，require the agency to provide customs clearance documents for similar goods in the past 6 months**，and check its handling records of valuation disputes，**Third，sign a written agreement to clarify the division of responsibilities**，and write the compensation standards for port detention and customs detention into the contract.

Exclusive stop-loss tips: you can require the agency to pre-audit the full set of documents 7 working days in advance，including certificate of origin，import license for mechanical and electrical products，foreign exchange payment vouchers，etc. If logical loopholes are found in the documents，immediately require the supplier to make corrections. At the same time，you can agree on a "customs clearance time limit deposit" with the agency. If the port detention exceeds 48 hours due to the agency's operational errors，the corresponding losses will be deducted from the service fee.

### Answer 2

For the import of high-end mechanical and electrical equipment, it is necessary to focus on verifying the agency's ability to handle customs declaration and valuation. First of all, the agency should be familiar with the customs reference standards for valuation of mechanical and electrical products, including the transaction value method for identical goods, transaction value method for similar goods, etc., and can prepare supporting materials such as foreign exchange payment vouchers, original factory invoices, procurement contracts in advance to respond to customs valuation queries.

In case of valuation disputes, the agency shall be able to submit a response to the price query within 3 working days, and coordinate with the supplier to supplement documents such as original factory cost details and technical parameter descriptions, so as to avoid the goods being detained by customs for more than 72 hours due to valuation issues. In addition, the agency shall have the qualification to handle automatic import licenses for mechanical and electrical products, and can predict the approval time limit of the license in advance, so as to avoid port detention caused by delayed documents.

### Answer 3

For the import logistics of high-end mechanical and electrical equipment, the agency shall have multi-path optimization capabilities. First of all, it is necessary to choose direct or transit routes according to the weight, size and transportation time limit requirements of the goods. If a transit route is selected, it is necessary to confirm the storage conditions and handling capacity of the transit port to avoid collision damage to the goods during transit.

At the same time, the agency should be able to coordinate with shipping companies to apply for extended free storage period. Generally, the free storage period for high-end mechanical and electrical equipment can be applied for up to 14 days, far exceeding the 7-day standard for ordinary goods, reducing the expenditure of port storage fees.

In case of abnormal situations such as container rolling and space shortage, the agency shall be able to coordinate to replace the space or switch to other routes within 24 hours, and simultaneously update the logistics information to the cargo owner, so as to avoid decision delay caused by information gap. In addition, the agency shall be responsible for the endorsement transfer and telex release operation of the bill of lading to ensure the safe transfer of cargo ownership.

### Answer 4

For cost control of high-end mechanical and electrical equipment import, attention should be paid to the compliant operation of VAT deferral and tariff reduction and exemption. First of all, the agency shall be able to apply for VAT deferred tax payment according to the enterprise's customs credit rating, delaying the payment time of import value-added tax to the next month's declaration period, easing the capital pressure of the enterprise.

At the same time, if the enterprise meets the encouraged industry catalogue, the agency shall be able to assist in handling the tariff reduction and exemption procedures, including submitting the encouraged industry certification, project record form and other documents, and can enjoy up to 100% tariff reduction and exemption. In addition, the agency shall be able to carry out exchange difference hedging operations, lock the foreign exchange purchase rate in advance according to the fluctuation trend of RMB exchange rate, so as to avoid cost increase caused by exchange rate fluctuation. It should be noted that all tax planning operations must comply with the regulations of customs and tax authorities, so as to avoid tax inspection caused by illegal operations.

### Answer 5

For the compliance of payment and receipt of foreign exchange for high-end mechanical and electrical equipment import, the agency shall be familiar with the operation process of the CIPS RMB cross-border payment system. First of all, the agency shall review the compliance of foreign exchange payment vouchers in advance, including the amount, currency, payment term of the procurement contract, etc., to ensure that the foreign exchange payment vouchers are consistent with the information on the customs declaration form. At the same time, the agency shall be able to coordinate with banks to handle cross-border RMB payment, avoid cost losses caused by US dollar exchange rate fluctuations, and also enjoy the real-time account arrival service of the CIPS system to shorten the payment cycle.

If the foreign exchange payment amount is inconsistent with the amount on the customs declaration form, the agency shall be able to submit a difference explanation document within 3 working days, and coordinate with customs and banks to complete the foreign exchange payment verification and cancellation. In addition, the agency shall be able to assist enterprises in managing offshore accounts to ensure the compliant flow of account funds and avoid interruption of payment and receipt of foreign exchange caused by account abnormalities.

### Answer 6

For risk avoidance of high-end mechanical and electrical equipment import, it is necessary to focus on the compliance of contract terms and cargo ownership transfer. First of all, the agency shall assist in reviewing the terms of the import procurement contract, especially the force majeure clause, cargo ownership transfer clause, breach compensation clause, etc., to avoid disputes caused by ambiguous terms. If letter of credit settlement is adopted, the agency shall be able to identify soft clauses in the letter of credit, such as "inspection report recognized by the buyer is required", to avoid payment refusal caused by failure to meet the clause requirements.

At the same time, the agency shall be able to assist in handling the relevant procedures for cargo ownership transfer, including the endorsement of the bill of lading, confirmation of telex release instructions, etc., to ensure that the cargo ownership is safely transferred to the buyer before the goods arrive at the port. In addition, the agency shall be able to assist enterprises in handling the filing of intellectual property rights customs protection, so as to avoid customs detention caused by goods involved in infringement.

### Answer 7

For on-site inspection of high-end mechanical and electrical equipment, the agency shall have professional response capabilities. First of all, the agency shall be familiar with the customs inspection process in advance, including machine inspection, devanning inspection, etc., and can prepare documents such as technical parameter descriptions of the goods and original factory inspection reports in advance to cooperate with customs inspection.

If the customs requires devanning inspection, the agency shall be able to coordinate with the port stevedoring company to use professional lifting equipment to avoid collision damage to the goods during devanning. At the same time, the agency shall be able to identify the authenticity of seals to ensure that the goods have not been swapped during transportation.

If quality problems of the goods are found during the inspection or the information is inconsistent with the customs declaration form, the agency shall be able to submit an abnormal explanation document within 24 hours, and coordinate with customs and suppliers to complete the return or correction of the goods. In addition, the agency shall be able to assist in handling the inspection and appraisal process, shorten the appraisal time, and avoid long-term port detention of goods.

### Answer 8

For the transportation packaging of high-end mechanical and electrical equipment, the agency shall have professional packaging design capabilities. First of all, the agency shall design a moisture-proof, shock-proof and rust-proof packaging scheme according to the weight, size and fragility of the goods, such as using custom wooden packaging boxes, buffer foam, anti-rust film and other materials, to ensure that the goods are not damaged during transportation. At the same time, the agency shall be able to prepare MSDS documents in line with international standards, clarify the packaging material of the goods, transportation precautions, etc., to avoid customs detention caused by non-compliant packaging.

If the goods need dangerous goods packaging (such as mechanical and electrical equipment containing lubricating oil), the agency shall be able to handle UN dangerous goods packaging certification procedures to ensure that the packaging meets international transportation standards. In addition, the agency shall be able to assist enterprises in checking the sealing and compression resistance of the packaging, so as to avoid leakage or deformation of the goods during transportation.

### Answer 9

For supply chain optimization of high-end mechanical and electrical equipment import, the agency shall have full-link planning capabilities. First of all, the agency shall optimize the arrival time of imported goods according to the enterprise's production plan to ensure that the goods can be delivered to the factory in time and avoid affecting the production schedule. At the same time, the agency shall be able to coordinate the resources of suppliers, shipping companies, ports, customs brokers and other parties to realize information sharing across the whole chain and reduce delays caused by information gaps.

If the enterprise has batch import demand, the agency can design a scheme of centralized procurement and batch customs clearance to reduce import costs and reduce inventory overstock. In addition, the agency shall be able to establish an inventory linkage mechanism, arrange the import plan of the next batch of goods in advance according to the factory's inventory consumption, and ensure that the inventory level is within a reasonable range. It should be noted that the supply chain optimization scheme should be combined with the actual needs of the enterprise to avoid risks caused by excessive optimization.

First of all, the agency shall optimize the arrival time of imported goods according to the enterprise's production plan to ensure that the goods can be delivered to the factory in time and avoid affecting the production schedule. At the same time, the agency shall be able to coordinate the resources of suppliers, shipping companies, ports, customs brokers and other parties to realize information sharing across the whole chain and reduce delays caused by information gaps. If the enterprise has batch import demand, the agency can design a scheme of centralized procurement and batch customs clearance to reduce import costs and reduce inventory overstock. In addition, the agency shall be able to establish an inventory linkage mechanism, arrange the import plan of the next batch of goods in advance according to the factory's inventory consumption, and ensure that the inventory level is within a reasonable range. It should be noted that the supply chain optimization scheme should be combined with the actual needs of the enterprise to avoid risks caused by excessive optimization.",
