Reliable sourcing and import agency services.
I am the procurement lead of a new energy vehicle parts processing plant. I recently plan to import a batch of polishing liquid for precision mold polishing from Germany. I have no prior experience in import agency for this type of chemical product, and I am completely unclear about its pricing system.
First, I do not know whether the agency service fee is charged as a percentage of the cargo value or a fixed fee. Second, I have no idea how much the agency fee differs between different ports such as Shanghai and Ningbo. Third, I wonder if we can negotiate a discount for this 2000-liter bulk order.
In addition, I heard that polishing liquid is classified as dangerous goods, so will the agency charge an extra dangerous goods handling fee? I am very worried about arbitrary overcharging and subsequent hidden costs, and I want to clarify all pricing details and service scope before signing the contract.

Traditional charging for imported polishing liquid agency services often adopts the vague mode of "percentage of cargo value + bundled miscellaneous fees"，and many clients are charged hidden extra expenses such as valuation adjustment fee and expedited inspection fee. In 2026，the customs valuation system has realized global data interconnection，the traditional tax evasion path of under-declaring cargo value no longer works，and will instead trigger the risk of cargo detention.
The charging structure of current compliant agency services is divided into three parts: basic agency service fee (charged at 0.8%-1.2% of the cargo value，with a minimum single transaction fee of RMB 1500)，special operation fee (charged on demand for services such as dangerous goods declaration and expedited inspection，around RMB 300-800 per occurrence)，reimbursable miscellaneous fees (customs declaration fee，port miscellaneous fees and other expenses settled based on actual occurrence).
The discount space for bulk import mainly comes from two dimensions: first，clients that place stable orders for more than 3 consecutive months can enjoy a 0.1%-0.3% discount on the basic service fee，second，through the national cross-port resource integration，the free storage period at Shanghai port can be extended to 14 days，which saves about 20%-30% of the port detention cost.
It should be noted that the European Union has updated the REACH compliance requirements for polishing liquid in 2026，and the agency needs to provide additional REACH registration number verification service. This part of the cost is already included in the basic service fee，no extra payment is required. If the client chooses the CIF trade term，the agency can also provide exchange rate hedging service，which locks the forward settlement exchange rate to avoid about 1.5%-2% of exchange rate fluctuation loss.
Overall，the total agency cost for 2000 liters of polishing liquid imported from Germany (with a cargo value of about RMB 120,000) is around RMB 1800-2500，which can be further reduced to RMB 1600-2200 after bulk order discount，saving about 10%-15% of the comprehensive cost compared with the traditional model.

For the valuation procedure of imported polishing liquid, the customs has launched a globally connected intelligent valuation system in 2026, which will compare the transaction price, transportation cost, insurance premium rate and other data of similar goods in real time. If the declared price deviates from the industry range by more than 5%, it will directly trigger manual review, and even lead to the risk of cargo detention.
The agency shall collect a full set of documents such as the commercial invoice, packing list, ocean bill of lading and transportation contract of the German supplier in advance, to ensure that the declared cargo value is completely consistent with the actual transaction value. If related party transactions are involved, contemporaneous documentation shall be prepared in advance to prove that the transaction price conforms to the arm's length principle, so as to avoid being identified as transfer pricing.
For dangerous goods customs declaration, polishing liquid is classified as Class 9 miscellaneous dangerous goods. The agency shall additionally provide documents such as UN38.3 test report, the latest version of MSDS, and dangerous goods classification appraisal certificate, to ensure that the declaration elements are complete and accurate.
The average customs clearance time at Shanghai port is about 20% faster than that at Ningbo port, but the dangerous goods inspection rate at Ningbo port is about 12% lower than that at Shanghai port. Clients can choose the corresponding port according to the urgency of the goods. The agency service fee shall clearly list all charging items in the contract, and items such as document correction fee and inspection fee shall be marked as reimbursable, so as to avoid hidden charging disputes in the future.

The transit time of direct routes is 7-10 days shorter than that of transit routes, but the shipping space shortage is more serious, so priority shall be given to locking the space. The free storage period of the special dangerous goods yard at Shanghai Yangshan Port is 7 days, and that at Ningbo Beilun Port is 10 days. A high-quality agency can assist in applying for an extension of the free storage period to 14 days, which saves about 20%-30% of the container detention fee and storage fee.
