Tariff Calculation Method: Types of Import Tariff Rates, Determination of Duty-Paid Value, and Calculation Formula

I. Basic Concepts of Customs Duty

1.1 What is Customs Duty?

Customs Duty is a tax levied by a country's customs on imported and exported goods. It is an indirect tax—the tax burden is ultimately borne by consumers.

In China, the import process involves two types of taxes: - Customs Duty— Calculated as HS Code tax rate × Dutiable value - Import VAT— Calculated as (Dutiable value + Customs Duty) × VAT rate (13% or 9%)

Consumption Tax (levied only on specific goods, such as tobacco, alcohol, cosmetics, and automobiles).

1.2 The Role of Customs Duty

• Fiscal Revenue: Customs duty is a component of national fiscal income.
• Protecting Industries: Imposing higher tariffs to protect domestic competitive industries.
• Regulating Trade: Encouraging or discouraging the import/export of specific goods through tariff rates.
• Policy Tool: Tariff reductions and exemptions serve as bargaining chips in free trade agreements and trade negotiations.

II. Types of Customs Duty Rates

China's customs tariff rates are categorized as follows, arranged from lowest to highest:

2.1 Detailed Explanation of Six Rate Types

① Conventional Tariff Rate (Lowest) - Applicable Conditions: Goods originate from countries with which China has signed Free Trade Agreements (FTAs) and comply with the rules of origin of the agreement. - Specific Levels: The ultimate target for most conventional rates is 0% (e.g., the China-ASEAN FTA has already achieved nearly comprehensive zero tariffs). - Practical Tips: A valid Certificate of Origin (FORM E/FTA Certificate, etc.) must be submitted when declaring to apply this rate. - Example: FORM E can reduce tariffs on Chinese mechanical and electrical products exported to ASEAN from 5%-15% to 0%.

② Preferential Tariff Rate - Applicable Conditions: From Least Developed Countries (LDCs) that have diplomatic relations with China, such as some African countries, Cambodia, Laos, Myanmar, etc. - Specific Levels: 0% for the vast majority of products. - Practical Tips: A preferential Certificate of Origin must be provided upon import.

③ Temporary Tariff Rate - Applicable Conditions: Temporarily lower rates set annually by the state for certain imported goods, usually lower than the MFN rate. - Specific Levels: For example, in 2025, the temporary import tariff rate for some resource products was reduced to below 1%. - Practical Tips: The temporary rate takes precedence over the MFN rate. It is adjusted annually with the "Import and Export Tariff List"; the latest version must be consulted.

④ Most-Favored-Nation (MFN) Tariff Rate (Baseline Rate) - Applicable Conditions: From WTO member countries (approximately 160 countries and regions worldwide, including China's major trading partners like the USA, EU, Japan, etc.) - Specific Levels: Varies by product, typically between 0% and 50%, with most industrial products ranging from 5% to 15%. - Practical Tips: China applies the MFN rate to most imported goods; it serves as the "baseline" for calculating customs duty.

⑤ General Tariff Rate (Highest) - Applicable Conditions: From non-WTO member countries or countries without a reciprocal trade agreement with China. - Specific Levels: Usually 2 to 5 times the MFN rate. - Practical Tips: Rarely encountered in actual trade (China applies MFN rates to most countries it trades with).

⑥ Tariff Quota Rate - Applicable Conditions: For specific imported goods within the quota quantity (e.g., wheat, corn, sugar, cotton, etc.). - Specific Levels: The in-quota rate is significantly lower than the out-of-quota rate (e.g., 65% out-of-quota vs. only 1% in-quota). - Practical Tips: Quotas must be applied for in advance; quantities are limited, allocated on a first-come, first-served basis.

Conventional Rate / Preferential Rate / Temporary Rate (choose the lowest)
        ↓
    Tariff Quota Rate (in-quota)
        ↓
    MFN Rate (Baseline)
        ↓
    General Rate (Highest)

2.3 Export Duties

Most goods exported from China are not subject to export duties (to encourage exports). Export duties are only levied in the following situations:

• "Two Highs and One Resource" products (e.g., certain steel, fertilizers, rare earths)
• Specific resource-based products (e.g., certain mineral products)
• Rate: Generally low (e.g., 20%-40%, ad valorem).

III. Dutiable Value

3.1 What is Dutiable Value?

Dutiable Value (Customs Value) is the base price for calculating customs duty.

3.2 Special Adjustments for Import Dutiable Value

Customs has specific rules for determining import dutiable value:

Fees to be Included in Dutiable Value: - Commissions and brokerage fees paid by the buyer. - Container and packing costs. - Materials and tooling costs for production assistance. - Royalties and license fees related to the imported goods. - Proceeds from the resale/disposal accruing to the seller.

Fees NOT to be Included in Dutiable Value: - Post-importation construction/installation/maintenance/technical service fees. - Import customs duty and VAT.

3.3 Valuation for Related Party Transactions

Transaction prices between related parties must undergo Customs appraisal. If Customs believes the related party transaction price has influenced the transaction value (i.e., transfer pricing is too low or too high), Customs has the authority to adjust it in the following order:

Transaction Value → Transaction Value of Identical Goods → Deductive Value → Computed Value → Fallback Method

IV. Customs Duty Calculation Formulas

4.1 Ad Valorem Duty (Most Common)

Customs Duty = Dutiable Value (CIF) × Duty Rate
Import VAT = (Dutiable Value + Customs Duty) × VAT Rate

Example: Importing a machine with CIF value of 100,000 Yuan, duty rate 8%, VAT rate 13%.

Customs Duty = 100,000 × 8% = 8,000 Yuan
VAT = (100,000 + 8,000) × 13% = 14,040 Yuan
Total Tax = 8,000 + 14,040 = 22,040 Yuan

4.2 Specific Duty (Levied by Quantity)

Customs Duty = Quantity of Goods × Duty Rate per Unit

Example: Importing 5,000 liters of beer, specific duty rate is 3 Yuan/liter.

Customs Duty = 5,000 × 3 = 15,000 Yuan

4.3 Compound Duty (Ad Valorem + Specific)

Customs Duty = Ad Valorem Part (CIF × Ad Valorem Rate) + Specific Part (Quantity × Duty Rate per Unit)

4.4 Sliding Duty (Rate varies with Price)

Applicable to some agricultural products; a higher rate is applied when the import price is low, and a lower rate when the price is high (to protect domestic agriculture).

V. Customs Duty Reduction and Exemption Policies

5.1 Common Scenarios for Duty Reduction/Exemption

5.2 Application for Duty Relief

Policy-based relief requires a prior application for the "Certificate of Duty Reduction/Exemption," see details:

• Exemption for imported equipment in domestic/foreign-invested projects encouraged by the state (requires approval from DRC/commerce departments).
• Exemption for scientific research/teaching supplies (requires certification from science/technology authorities).
• Exemption for specialized rehabilitation products for the disabled (requires proof from the Disabled Persons' Federation).

VI. Practical Duty Estimation

6.1 Steps for Quick Estimation

① Look up the 8-digit HS code for the product.
② Confirm the applicable rate type (MFN/Temporary/Conventional).
③ Determine the dutiable value (Import: CIF / Export: FOB).
④ Apply the formula to calculate customs duty.
⑤ Calculate import VAT simultaneously.

6.2 Methods for Checking Rates

6.3 Calculation Example

Scenario: Importing precision instruments from Japan, CIF value 2,000,000 Yuan. - HS Code: 9031.80.90 (Measuring/checking instruments) - MFN Rate: 5% - RCEP Conventional Rate (Japan): 0% (applying RCEP preferential rate) - VAT Rate: 13%.

Clearly, utilizing FTA tariff rates can significantly reduce import costs. This highlights the importance of accurate HS code classification and Certificate of Origin processing.

VII. Frequently Asked Questions about Duty Calculation

Q: If imported goods qualify for both MFN rate and temporary rate, which takes precedence? A: The temporary rate takes precedence over the MFN rate (temporary rates are usually lower).

Q: Which is lower, the conventional rate or the temporary rate? A: Neither is always lower; both are preferential rates. Apply the lower one, but they cannot be combined.

Q: Is the dutiable value of imported goods tax-inclusive or tax-exclusive? A: The dutiable value is the CIF value, which does not include import duty and VAT. All related import taxes and fees are added on top of the dutiable value.

Q: Can customs duty be paid in a currency other than RMB? A: It must be paid in RMB. Customs applies a monthly exchange rate for conversion (the applicable customs exchange rate for each month can be found on the GAC website).

Q: When is export duty collected? A: It is collected during the export customs declaration process. Currently, very few types of export goods are subject to export duties (mainly some resource-based products).
