# Price Composition and Transparent Charging Standard for Original Imported Frequency Converter Agency

## Core Cost Composition of Original Imported Frequency Converter Agency

Many manufacturing enterprises in Shanghai and surrounding areas,when purchasing original imported frequency converters,are most concerned about the price of agency services -- they worry that low quotations hide hidden charges,and unclear fees will lead to over-expenditure in the later period.Recently,Ms.Xiang,an owner of an intelligent equipment company,complained to us that the price quoted by her previous agency seemed cheap,but during customs clearance,there were suddenly extra "inspection expediting fee" and "document review fee",which cost nearly 15% more than the budget.In fact,the agency price of original imported frequency converters is not a "one-time fixed price",but a combination of multiple types of costs.Today we will break down these costs to give you a clear understanding.

### I.Customs and Commodity Inspection Related Fees (Non-negotiable,Statutorily Mandatory)

These fees are mandatory to be paid to customs and commodity inspection authorities during the import process.They are directly related to cargo supervision and inspection and quarantine,most charging methods are linked to cargo value and quantity,and there is no room for negotiation.Specific items include:

- **Tariff**: According to the HS code of the frequency converter (the HS code for some energy-saving frequency converters is 85371090 in 2026),the tariff rate is about 5%-8%,and the billing base is the CIF value of the goods (cost + insurance + freight);
- **Import Value-added Tax**: The fixed tax rate is 13%,the billing base is (CIF value + tariff) × 13%,which can be deducted with the customs value-added tax payment certificate after import;
- **Commodity Inspection Fee**: If the frequency converter is a legally inspected commodity (such as industrial frequency converters with communication functions),it is charged at 0.1%-0.3% of the cargo value,and the invoice is directly issued by the commodity inspection agency;
- **Customs Inspection Fee**: If the goods are randomly inspected by the customs,it is charged according to the number of inspections,about 300-500 RMB per time.If the goods are subject to key inspection due to non-compliant declaration,the fee will be higher.

### II.Agency Service Fee (Negotiable,Core Service Charge)

This is the charge for core services provided by the agency company,including customs declaration,document preparation,foreign exchange receipt and payment,foreign exchange settlement and purchase,etc.It is generated because the agency company needs to invest manpower and time to handle the whole import process.The charging method is flexible and can be negotiated according to cargo volume and cooperation cycle.There are two conventional charging methods in the Shanghai market in 2026:

- **Charging by proportion of cargo value**: 1.5%-3% for cargo value below 1 million RMB,1%-2% for cargo value between 1 million RMB and 5 million RMB,and can be reduced to 0.8% for enterprises with annual purchase volume exceeding 10 million RMB;
- **Charging per order**: 3000-6000 RMB per order for single-ticket cargo value below 500,000 RMB,5000-10000 RMB per order for single-ticket cargo value above 500,000 RMB,including conventional document preparation,customs declaration and inspection,foreign exchange receipt and payment and other services.

### III.International Logistics and Warehousing Fees (Generated on Demand,Optimizable)

These fees are directly related to cargo transportation and warehousing requirements.They are generated for transporting frequency converters from foreign ports to domestic warehouses,and are calculated according to transportation mode,volume/weight,and storage days.Discounts can be negotiated through long-term cooperation or large cargo volume.Specific items include:

- **International Transportation Fee**: Sea freight (from Hamburg,Germany to Yangshan Port,Shanghai) is about USD 2-5 per cubic meter,air freight is about USD 10-20 per kilogram.Due to the stable global supply chain in 2026,sea freight prices have dropped by about 10% compared with 2025;
- **Domestic Warehousing Fee**: Ordinary warehouses are about 1-3 RMB per cubic meter per day.If the frequency converter requires constant temperature and humidity storage (such as precision frequency converters),the fee is about 5-8 RMB per cubic meter per day;
- **Delivery Fee**: From the port warehouse to the enterprise’s factory,it is charged according to transportation distance and cargo weight,about 0.8-1.2 RMB per kilogram within 100 kilometers.

## Impact of Different Situations on Cost Structure

| Trade Term / Cargo Type | Proportion of Customs Fees | Proportion of Agency Service Fee | Proportion of Logistics and Warehousing | Estimated Total Cost (Cargo Value 1 Million RMB) |
| --- | --- | --- | --- | --- |
| FOB + Ordinary Frequency Converter | About 18% (6% tariff + 13% VAT + 0.5% commodity inspection) | About 2% | About 5% (sea freight + domestic warehousing) | About 250,000 RMB |
| CIF + Ordinary Frequency Converter | About 18% (tariff + VAT + commodity inspection) | About 1.8% | About 3% (includes pre-arrival logistics from abroad) | About 228,000 RMB |
| EXW + Precision Frequency Converter | About 19% (7% tariff + 13% VAT + 0.6% commodity inspection) | About 2.5% | About 7% (sea freight + constant temperature warehousing) | About 285,000 RMB |
| DDP + Precision Frequency Converter | About 19% (tariff + VAT + commodity inspection) | About 3% | About 8% (door-to-door transportation + constant temperature warehousing) | About 300,000 RMB |

## Beware of Hidden Charging Traps in Agency Pricing

In Shanghai’s foreign trade agency market in 2026,some small agencies attract customers with "low prices" and then make up the difference through hidden charges.Common traps include:

- **False "Inspection Expediting Fee"**: There is no additional fee for customs inspection expediting,but some agencies charge 2000-3000 RMB per time on the grounds of "expedited customs clearance",and actually do not provide any expediting service;
- **Ambiguous "Lump-sum Fee"**: They claim "lump-sum fee of X ten thousand RMB covers all",but do not specify whether it includes commodity inspection fee and overdue storage fee.If the goods need to be stored for 5 extra days,they will charge an extra 500-1000 RMB;
- **Exchange Rate Fluctuation Trap**: When processing import payment,the agency does not lock the exchange rate in advance,and settles according to the daily fluctuating exchange rate.If the exchange rate rises by 1%,the enterprise needs to pay an extra 10,000 RMB (for 1 million RMB cargo value).

## How to Choose an Original Imported Frequency Converter Agency with Transparent Charging

When choosing an agency,you should not only look at the superficial price,but also pay more attention to cost transparency.Manager Dai of Zhongshen suggests that enterprises judge from three aspects:

First,require the agency to provide a **detailed cost list**,clarify the name,billing basis and amount of each fee.For example,tariff should be marked with the corresponding tax rate of HS code,logistics should be marked with specific route and volume/weight;

Second,confirm whether the agency has **formal qualifications**,such as customs declaration and inspection qualification (customs Class A enterprises are preferred),foreign exchange receipt and payment qualification (bank-authorized foreign exchange agency qualification),avoid unqualified "intermediaries";

Finally,refer to the **cooperation cases** of the agency.For example,among the intelligent equipment enterprises served by Zhongshen,80% of customers choose long-term cooperation because of transparent charging,and there have been no hidden charging disputes in the past three years.
