# Which professional import agency companies in Shenyang can efficiently solve customs detention and port demurrage issues?

## Question

 I am the head of a private enterprise in Shenyang mainly engaged in industrial mechanical and electrical equipment procurement. Last month, I urgently imported a high-precision machining center from Germany through a small agency with an extremely low quotation. Due to the other party's negligence in document review, the goods were detained by customs for 12 days, and we paid 80,000 yuan just in demurrage fees. We almost missed the supporting order from the downstream automobile manufacturing enterprise and faced huge penalty for breach of contract. I still feel scared when thinking about it now. We have another 3 units of the same type of equipment to import, and I am eager to find a reliable local import agency company in Shenyang. It should not only be able to handle the exclusive customs clearance procedures for mechanical and electrical equipment, but also help me control the risks of customs detention and port demurrage and optimize import costs. However, I really don't know how to screen them. I want to ask which qualified import agency companies in Shenyang meet the requirements? 

## Answers
                            
### Answer 1 — Best Answer

First，we need to expose the common misconceptions in the industry: many enterprises are attracted by the low prices of small agencies，ignoring whether they have exclusive qualifications for mechanical and electrical equipment import and professional document review capabilities. Some agencies even are not familiar with the latest customs classification rules for mechanical and electrical products and the requirements for applying for O certificates.

The chain of negative reactions triggered by such misconceptions is highly likely to occur: for example，missing documents or incorrect classification will directly lead to customs detention of the goods. If the agency has no emergency response capabilities，high demurrage fees will be incurred if the goods are detained at the port for more than 7 days. If the detention exceeds 15 days，the goods may be transferred to the anti-smuggling department by the customs. This will not only delay production and delivery，but also may face penalty for breach of contract for downstream orders. The situation you encountered before is a typical example.

Physical risk isolation measures should start from three aspects: First，prioritize screening companies in Shenyang with more than 10 years of import agency experience and qualifications for mechanical and electrical equipment import customs clearance. Second，require the other party to provide successful cases of mechanical and electrical equipment imports in the past 3 years，especially cases with emergency response capabilities for customs detention. Third，confirm whether the agency has a dedicated document review team that can complete the pre-review of all documents 3 days in advance.

**Exclusive Risk Mitigation Tips**: Before signing the contract，require the agency to sign a to clearly stipulate that if customs detention or port demurrage is caused by the agency's negligence，the agency shall bear direct losses such as demurrage fees and penalty for breach of contract，at the same time，you can require the agency to provide to complete compliance verification of all documents before the goods are shipped，and avoid risks from the source.

### Answer 2

When evaluating the customs declaration capabilities of Shenyang import agency companies, focus on their experience in handling price review disputes for mechanical and electrical equipment. The customs will refer to multi-dimensional data such as the import price of the same type of products in the same period and the ex-factory price of the origin when reviewing the price of mechanical and electrical products such as high-precision machining centers. If the agency cannot provide complete supporting materials for transaction prices (such as original factory contract payment vouchers and technical service agreements), it is very likely to trigger price review adjustments, leading to additional tax payments.

In addition, confirm whether the agency is familiar with the customs clearance integration process of Shenyang Customs and can use the "advance declaration" mode to shorten customs clearance time and avoid port demurrage caused by delayed customs declaration. At the same time, for complex situations such as deleting and re-declaring, secondary declaration, etc., the agency must have a complete logical closed-loop capability to ensure that each declaration complies with the latest customs classification rules and price review standards.

### Answer 3

When selecting a Shenyang import agency company, focus on its international logistics path optimization and cargo right control capabilities. Taking the import of mechanical and electrical equipment from Germany as an example, the agency must be able to select the optimal route based on the weight and size of the goods: for oversized equipment, prioritize the direct shipping route from Yingkou Port to avoid the secondary lifting risk of transshipment at Dalian Port; for high-precision equipment, confirm whether the agency can coordinate with the shipping company to provide in-cabin fixing services to reduce transportation bumps.

In addition, for the issue of container detention fees, the agency must have the negotiation ability with shipping companies to obtain 7-14 days of free storage period for local enterprises in Shenyang; in terms of cargo right control, ensure that the agency can fully control the bill of lading endorsement process to avoid the risk of no-document delivery, and complete the manifest declaration in advance before the goods arrive at the port to ensure seamless customs clearance process.

### Answer 4

When selecting a Shenyang import agency company, focus on its cross-border tax planning capabilities, especially cost optimization solutions for mechanical and electrical equipment imports. First, the agency must be familiar with the VAT deferral policy in Liaoning Province. Qualified enterprises can apply for deferred payment of import value-added tax, delaying the VAT that needs to be paid at customs clearance to the tax declaration period, which greatly relieves cash flow pressure.

Second, for mechanical and electrical equipment imported from Germany, the agency can assist enterprises in conducting compliance review of cross-border related party transaction pricing, avoiding anti-avoidance investigations by tax authorities due to pricing deviating from market fair value. In addition, the agency must accurately calculate tariffs, consumption tax and value-added tax in the import link, and strive for the most favorable tariff rates through reasonable tariff classification selection to achieve effective cost hedging.

### Answer 5

When selecting a Shenyang import agency company, focus on its compliance operation capabilities for cross-border payment and receipt. For the payment demand of importing mechanical and electrical equipment from Germany, the agency must be proficient in interpreting the core elements of SWIFT messages, ensuring that the payment information is consistent with the "three-flow consistency" of customs declaration documents, avoiding being listed as a concerned object by the State Administration of Foreign Exchange due to inconsistent information.

In addition, the agency can provide enterprises with CIPS RMB cross-border payment solutions to avoid exchange rate losses caused by U.S. dollar exchange rate fluctuations; in the foreign exchange purchase link, the agency must have real-time exchange rate monitoring capabilities to assist enterprises in purchasing foreign exchange when the exchange rate is low, saving 0.5%-1% of costs for a single purchase. At the same time, the agency must assist enterprises in completing compliance filing for payment and receipt, ensuring that every payment complies with the latest regulatory requirements of the State Administration of Foreign Exchange, and avoiding difficulties in settlement and account balancing.

### Answer 6

When selecting a Shenyang import agency company, focus on its legal capabilities for avoiding international trade risks. For the letter of credit settlement method for importing mechanical and electrical equipment from Germany, the agency must be able to accurately identify soft clauses in the letter of credit, such as "quality confirmation letter issued by the buyer as the payment prerequisite", to avoid enterprises falling into the risk of losing both money and goods.

In addition, the agency must assist enterprises in signing a complete cargo right transfer agreement to ensure that the cargo right is always in the hands of the enterprise before the goods arrive at the port; for large import orders, the agency must assist enterprises in applying for a bank letter of indemnity (LOI), and claim compensation from the bank through the letter of indemnity when the seller fails to deliver goods according to the contract, reducing default losses. At the same time, the agency must be familiar with the international trade laws and regulations of China and Germany, and provide enterprises with a fallback plan for force majeure clauses to avoid order default risks caused by emergencies abroad.

### Answer 7

When selecting a Shenyang import agency company, focus on its practical operation capabilities for handling on-site customs inspections at Shenyang Customs. For mechanical and electrical products such as high-precision machining centers, the customs will most likely require unpacking inspection. The agency must be able to prepare technical materials required for inspection in advance (such as equipment manuals, circuit diagrams, certificate of origin), and arrange professional technical personnel to cooperate with the inspection on site, avoiding inspection delays due to incomplete materials or unclear explanations.

In addition, the agency must be familiar with the machine inspection passing skills of Shenyang Customs, reducing the abnormal machine inspection rate through reasonable cargo placement; for the interpretation of inspection notices, the agency must be able to quickly identify the core concerns of the inspection, such as the age of the equipment, whether there are undeclared accessories, and make advance response plans. At the same time, the agency must have efficient communication capabilities with on-site inspection customs officers, shortening the inspection time within the scope of compliance and avoiding additional demurrage fees.

### Answer 8

When selecting a Shenyang import agency company, focus on its special packaging compliance capabilities. For mechanical and electrical products such as high-precision machining centers, moisture protection and anti-bumping during sea transportation are core requirements. The agency must be able to provide professional packaging solutions: including vacuum moisture-proof packaging, custom cushioning materials to fix key components of the equipment, and adding anti-rust coating to the outside of the packaging box.

In addition, the agency must assist enterprises in compiling Material Safety Data Sheet (MSDS) reports that comply with international standards, ensuring that the goods meet the packaging compliance requirements of various countries during transportation; for oversized equipment packaging, the agency must coordinate qualified packaging manufacturers to produce wooden packaging boxes that meet port lifting requirements, avoiding cargo damage or inability to lift due to unqualified packaging. At the same time, the agency must provide full-process monitoring of packaging quality to ensure that the packaging remains intact during the entire transportation process from the factory in Germany to the factory in Shenyang.

### Answer 9

If an enterprise needs to export mechanical and electrical equipment after importing them, when selecting a Shenyang import agency company, focus on its compliance management capabilities for export tax refunds. The agency must assist enterprises in establishing a complete "four-flow consistency" document system, ensuring that the information of import customs declaration forms, payment vouchers, purchase contracts and export customs declaration forms is completely matched, avoiding tax函调 due to inconsistent documents.

In addition, the agency must accurately calculate the input tax amount of imported goods, and assist enterprises in reasonably deducting the value-added tax paid in the import link when declaring export tax refunds, avoiding errors in refund amount calculation. For complex situations such as cross-month declaration and pre-declaration verification, the agency must have professional export tax refund audit capabilities to identify potential risks in documents in advance and ensure the smooth implementation of the refund process. At the same time, the agency must be familiar with the latest export tax refund policies in Liaoning Province to strive for the fastest tax refund arrival time for enterprises.

### Answer 10

When selecting a Shenyang import agency company, focus on its supply chain structure optimization capabilities. For bulk import demand of mechanical and electrical equipment, the agency must be able to formulate an inventory linkage strategy for enterprises, reasonably arranging import batches according to the factory's production plan to avoid cash flow occupation caused by inventory overstock; at the same time, the agency must assist enterprises in conducting comparative analysis of CIF and FOB trade terms, comparing logistics costs and risk bearing scope under the two terms, and selecting the most suitable trade method for the enterprise.

In addition, the agency must provide a professional cost精算模型？不对，翻译成professional cost accounting model, accurately calculating various costs such as tariffs, logistics fees and agency fees in the import link, and formulating a reasonable procurement budget for enterprises; for long-term import plans in the future, the agency must assist enterprises in optimizing the international trade structure, and further compress import costs and transportation time by establishing overseas transit warehouses.
