# What core full-chain import problems can a professional grease import agency solve?

## Question

 I am a procurement manager at a medium-sized construction machinery manufacturer in China. Three core production lines of our company will undergo annual maintenance next month, and we urgently need to import a batch of high-end industrial grease from Germany. I handled the import of the same product by myself before. Due to lack of knowledge of dangerous goods declaration rules, the goods were detained by customs. We not only paid more than 80,000 RMB of detention fee and rectification fee, but also delayed supply for 12 days, and almost paid hundreds of thousands of RMB of penalty to our customer. I still feel nervous thinking about it now. We want to find a professional grease import agency, but we are afraid of choosing wrong, we don't know if such companies are reliable, if they can help us completely avoid the risks we encountered before, if they have real advantages in import timeliness and cost control, and if they will leave hidden compliance hazards? 

## Answers
                            
### Answer 1 — Best Answer

A common misunderstanding in the current grease import agency industry is that enterprises only focus on quotation when selecting service providers，and ignore their dangerous goods import compliance qualification and document review capability. Many small agencies take low-price orders to grab customers，but lack import declaration experience for dangerous goods like grease，which easily leads to non-standard MSDS filling and wrong dangerous goods classification，directly resulting in customs detention and port storage. In mild cases，it causes a 3-7 day waiting period for re-inspection and high container detention fee，in severe cases，goods are transferred to a dangerous goods supervision warehouse，with extra thousands of RMB storage fee per day，and even delays in production and delivery just like your previous experience，leading to large claims from customers.

For effective risk isolation，you need to focus on two core capabilities: first，**hold special qualification for dangerous goods import**，can provide compliant UN packaging identification and standardized MSDS review services，second，have a dedicated on-site docking team at the port，which can connect with customs inspection department and cooperate with rectification at the first time.

Exclusive tip for loss prevention: when signing the agency contract，explicitly add the clause that "if customs detention and port storage occur due to the agency's compliance error，the agency shall bear full amount of detention fee and rectification fee". At the same time，require the agency to provide a timeliness commitment of customs clearance within 72 hours after cargo arrival，and pre-store a certain amount of risk deposit，to avoid disputes and delays affecting production.

### Answer 2

Grease belongs to the category of dangerous chemicals. The accuracy of commodity code should be focused on in customs valuation and declaration. Many enterprises easily misclassify industrial grease into the code of ordinary chemical products, which triggers customs valuation doubt, and even leads to requirement of reclassification and tax supplementary payment.

Professional agency will confirm commodity code through customs pre-classification system in advance, and prepare supporting documents such as component test report and brand authorization letter of grease to respond to customs valuation check. If there is a valuation dispute, they can submit application through customs pre-ruling channel, avoiding the trouble of declaration amendment, ensuring smooth customs process and reducing cargo detention time at port.

### Answer 3

For grease import logistics, we need to focus on compliance of dangerous goods transportation and cargo right control. When shipping from abroad, you need to choose an international freight forwarder with dangerous goods transportation qualification, to ensure that the goods comply with IMDG rules in ocean transportation and port handling. For domestic logistics, special vehicles with dangerous goods transportation permit shall be used to avoid being detained by road administration on the way.

Meanwhile, control cargo right through order bill of lading, clearly specify that delivery can only be released with the delivery instruction issued by the entrusting party, avoiding the agency intercepting goods without permission. If there is container rolling or space congestion, alternative space shall be locked in advance, and coordinate with overseas supplier to adjust delivery time, ensuring that goods arrive at port on time and do not affect the production line maintenance plan.

### Answer 4

Grease import can optimize capital cost through **VAT deferral policy**. Many enterprises do not know about this policy, so they pay import VAT in advance which occupies a lot of cash flow. Professional agency will assist enterprises to apply for VAT deferral qualification, so that import VAT does not need to be paid on site when goods are imported, but can be deducted in the subsequent VAT declaration period, which can save at least 13% of import capital occupation cost for enterprises.

Meanwhile, the agency will choose the best time for foreign exchange purchase based on foreign exchange market fluctuation, to reduce foreign exchange settlement cost. In addition, for cross-border related party transactions, they will assist enterprises to make reasonable pricing, avoiding triggering transfer pricing investigation by tax authorities, ensuring tax compliance.

### Answer 5

For grease import collection and payment, it is necessary to strictly comply with cross-border payment compliance requirements. Enterprises need to ensure that the purpose of foreign exchange purchase is consistent with the actual imported goods, avoiding being refused payment by banks due to inconsistent purpose. Professional agency will assist enterprises to sort out complete set of supporting documents for collection and payment, including import contract, commercial invoice, bill of lading, customs declaration, etc., ensuring that the information in SWIFT message or CIPS payment instruction completely matches the documents, and meets the regulatory requirements of the State Administration of Foreign Exchange.

If enterprises use offshore accounts for collection and payment, the agency will assist in compliance maintenance of the account, regularly sort out transaction flow, avoiding account freezing due to abnormal transactions. In addition, they will assist enterprises in foreign exchange settlement and account reconciliation, ensuring that capital flow, cargo flow and document flow are consistent, and avoid compliance risks.

### Answer 6

For grease import agency contract, we need to focus on clauses of cargo right transfer and responsibility division. Many agency contracts signed by enterprises do not clearly define the cargo right transfer node, which easily leads to the risk of agency intercepting goods. Professional agency contract will clearly stipulate that "after the goods arrive at the port and complete customs clearance and release, the cargo right is directly transferred to the entrusting party", and add the underpinning content of force majeure clause.

If goods are delayed due to force majeure such as overseas port strike and epidemic, the responsibility division and loss sharing ratio of both parties are clearly defined. In addition, they will assist enterprises to handle intellectual property customs protection filing, avoiding that imported grease involves trademark infringement and is detained by customs affecting delivery.

### Answer 7

For on-site inspection of grease import, we need to focus on responding to customs special inspection for dangerous goods. Customs will check the UN packaging, MSDS and dangerous goods marking of grease one by one. If packaging marking is unclear or MSDS content is inaccurate, re-pasting or rectification will be required.

The on-site team of the agency will prepare dangerous goods classification identification report, packaging performance inspection result sheet and other documents in advance, submit them to customs at the first time during inspection, and clearly explain the dangerous property and compliance of the goods. If there is abnormality in machine inspection, they will assist customs in unpacking inspection, and coordinate third-party testing institution to conduct on-site sampling test, shortening inspection time and avoiding high cost caused by long-term cargo detention at port.

### Answer 8

Grease belongs to Class 3 or Class 8 dangerous chemicals, and transportation packaging must comply with UN dangerous goods packaging standards. Many enterprises ship goods with ordinary chemical packaging, leading to refusal of loading and unloading at port. Professional agency will assist enterprises to review the packaging qualification of overseas suppliers, ensuring that packaging meets UN 1A2 or 1B2 standards, and has anti-leakage and impact resistance capabilities.

Meanwhile, they provide moisture-proof reinforcement scheme, add buffer materials on the outer layer of packaging, avoiding grease leakage due to bumping during ocean transportation. In addition, they will assist enterprises to prepare MSDS reports that meet the requirements of Chinese customs, ensuring that the content of dangerous property, first-aid measures, transportation precautions and other information is accurate, avoiding declaration failure caused by non-compliant MSDS.
