由 caicai8478 In international trade, the HS Code (Harmonized System Code), also known as the commodity code, is the “key code” used by customs authorities worldwide. It is a standardized commodity classification and coding system maintained by the World Customs Organization (WCO) and used by over 200 countries and regions.
Choosing the right HS Code is the most core, critical, and technical step in export customs clearance. Making the wrong choice can lead to customs clearance delays and additional fees at best, and fines, legal risks, and even credit downgrades at worst.
- Why is the HS Code so important?
The HS Code is like a product’s “identity card,” providing customs with the following information:
Applicable Tax Rate: Customs uses the HS Code to determine import tariffs and VAT rates.
Regulatory Requirements: The HS Code determines whether the product requires an export/import license, commodity inspection (such as the electronic ledger required for exports to China), animal and plant quarantine certificates, or endangered species certification.
Trade policy: This determines whether a product enjoys tariff preferences (such as those under various free trade agreements), is subject to anti-dumping and countervailing (“anti-dumping and countervailing”) measures, and has quota restrictions.
Trade statistics: Governments use HS codes to compile international trade data and formulate economic policies.
The consequences of choosing the wrong code are severe:
Underreporting/omission of taxes: This may be considered smuggling, leading to fines or even criminal prosecution.
Overreporting taxes: This leads to unnecessary costs and reduces product competitiveness.
Invoice-goods discrepancies: Goods may be detained and inspected at destination customs, resulting in high demurrage and inspection fees.
Failure to enjoy free trade agreement benefits: Due to incorrect coding, it is impossible to apply for a certificate of origin, resulting in customers being unable to enjoy tariff reductions.
Corporate credit rating downgrade: Frequent errors can affect a company’s credit rating in customs systems (such as China’s Authorized Economic Operator (AEO) certification).
II. HS Code Structure Analysis: Cracking the “Code”
A complete HS Code is typically 10 digits (used for Chinese exports). The global base consists of 6 digits, known as the HS sub-heading. The last 4 digits represent the country’s specific sub-heading, as determined by the country.
Let’s take the Chinese customs code for a “13-inch Apple MacBook Air with Retina Display,” 8471.3000.90, as an example:
Digital Segment Name Explanation This example (8471.3000.90)
First 6 digits: International HS subheading. Globally harmonized, established by the World Trade Organization (WCO). 8471.30
Digits 1-2: Chapter. Identifies the category to which the product belongs. 84: Nuclear reactors, boilers, machinery, mechanical appliances, and parts thereof.
Digits 3-4: Heading. More precise classification within the chapter. 71: Automatic data processing equipment and parts thereof.
Digits 5-6: Subheading. Further classification within the heading. 30: Portable automatic data processing equipment, weighing ≤10 kg.
Last 4 digits: Domestic subheading. Further classification defined by each country. 00.90
Digits 7-8: Domestic subheading. China refines this classification based on regulatory and statistical needs. 00
Digits 9-10: Domestic subheading Further refinement: 90: Other (may refer to products without other specific functions)
Key Point: When classifying, first accurately identify the first six digits of the international code, then determine the subsequent sub-codes for your country.
III. How to Choose the Right HS Code for Your Product?
This is a rigorous and patient process, following the “Three-Step Classification Method”:
Step 1: Identify the Classes and Sections
Read the Class and Chapter Notes: This is the most important step! The HS Code Catalog begins with the “General Rules of Classification,” followed by “Notes” at the beginning of each class and chapter. These notes have legal force and clearly define which products are included in this class/chapter and which are excluded. Never skip the notes and simply search based on the literal meaning!
Preliminary Identification: Based on your understanding of the product (material, function, and intended use), make a preliminary judgment on which general class it may belong to. For example:
Plastic Products → Chapter 39
Textiles → Chapters 50-63
Machinery → Chapter 84
Electrical Equipment → Chapter 85
Toys → Chapter 95
Step 2: Review Headings
In the chapter you’ve initially identified, read through all four-digit headings from beginning to end to find the heading that best matches your product description. A product may fit within multiple headings, so you’ll need to apply the “General Rules for Classification” to determine the correct description.
Common tools: China Customs’ “Tax Schedule of the People’s Republic of China” or the free online search tools provided by major customs brokers and logistics companies.
Step 3: Determine Subheadings
Within the identified four-digit heading, continue to review the five-, six-, eight-, and even ten-digit subheadings to find the most accurate description.
The General Rules for Interpretation (GRI) are the legal basis for resolving difficult classification issues. It consists of six rules, which must be applied in order. For example:
Rule 1: The headings of classes, chapters, and sub-chapter are for ease of reference only. It is the headings and the class and chapter notes that have legal force.
Rule 3: When a product appears to fall under two or more headings, it should be classified according to the “essential characteristics” principle.
IV. Practical Advice and Common Pitfalls
Make good use of tools, but be wary of blind faith:
Free search tools: They can be used for quick preliminary identification and understanding, but their databases may not be up-to-date or accurate, and should not be used as the basis for final declarations.
Customs Preliminary Ruling: For important commodities with uncertainties, the safest approach is to apply to the customs for a preliminary ruling on the classification of the goods. Written rulings issued by the customs are legally binding and can avoid subsequent risks.
Reference to peer and predecessor experience: Consult experienced customs brokers, freight forwarders, or industry colleagues, but be aware that their choices may be incorrect, so verify them yourself.
A detailed and accurate product description is key: The more detailed product information you provide to your customs broker or freight forwarder, the better, including:
Material (e.g., “100% cotton” or “65% cotton, 35% polyester”)
Function (is it “primarily used for…” or “also has…” functions)
Use (is it “household” or “industrial”)
Brand and model
Working principle
Common pitfalls:
Guessing directly based on the product name: For example, a “mobile phone case” could be made of plastic (3926), leather (4202), or metal (8306), all completely different.
Ignoring parts classification: Parts and accessories of a product are usually classified in the same heading as the entire product, but there are exceptions; please refer to the specific chapter notes.
Mixed goods: Goods made of different materials (e.g., wooden furniture with metal fittings) need to be classified according to the “essential characteristics” principle.
Summary
Selecting an HS code is not a simple “dictionary lookup” process; it is a technical task that requires logical reasoning, accumulated experience, and a rigorous attitude.
The key takeaway: Read the annotations, identify the chapters, understand the articles, apply the rules, and strive for accuracy.
When you’re unsure, seeking help from a professional customs broker or applying for a customs advance ruling is a far wiser option than blindly declaring. This “key code” is worth your time and effort to master.
