What Is the HS Code and How to Find It for Shipping from China to the USA, EU, or UK
Most import problems don’t start at customs. They start much earlier, with a single wrong number on a commercial invoice.
The Harmonized System (HS) code looks like a simple classification label, but in reality, it determines how your goods are taxed, whether they are restricted, how fast they clear customs, and even whether they are allowed into a country at all. For importers sourcing from China—especially those shipping to the USA, EU, UK, or other major markets—understanding HS codes is not optional. It is foundational.
This guide explains what HS codes really are, how they work globally, how to find the correct one for your product, and why getting it wrong can quietly damage your supply chain.
The Harmonized System is an internationally standardized product classification system developed and maintained by the World Customs Organization (WCO). It is used by more than 200 countries and customs territories to identify goods for trade statistics, customs clearance, and tariff calculation.
At its core, the HS code provides a common “language” for classifying products across borders. When a shipment moves from China to the USA or Europe, both customs authorities rely on HS codes to understand what the product is, what rules apply to it, and what duties or taxes should be charged.
The global HS system is structured into:
Chapters (2 digits): Broad product categories
Headings (4 digits): More specific product types
Subheadings (6 digits): Internationally standardized detail
National extensions (8–10+ digits): Country-specific classifications
The first six digits are consistent worldwide. Anything beyond that depends on the importing country’s tariff schedule.
Many new importers treat HS codes as a paperwork formality. In reality, HS codes directly affect four critical areas of your shipment.
First, duties and taxes. Customs authorities use HS codes to determine import duty rates, VAT, or GST. A different code—even for a very similar product—can change your landed cost significantly.
Second, customs clearance speed. Incorrect or vague codes often trigger manual inspections, document reviews, or customs queries. This can delay shipments by days or weeks.
Third, regulatory compliance. Some HS codes are linked to product safety rules, certifications, or licensing requirements. Misclassification can result in penalties or shipment seizure.
Fourth, trade data and audits. Customs agencies track import behavior using HS codes. Repeated misclassification increases the risk of audits or future shipment scrutiny.
In short, HS codes are not just about tariffs. They shape how your shipment is treated from origin to final delivery.
Understanding the structure makes HS codes easier to work with.
For example, consider a basic electric fan:
Chapter 84: Machinery and mechanical appliances
Heading 8414: Air or vacuum pumps, air compressors, fans
Subheading 8414.51: Table, floor, wall, window fans
The international HS code might be: 8414.51
If you are importing into the USA, this could extend to 8414.51.9090, while the EU or UK would use a different extension.
The key point is this: the first six digits describe the product globally. The remaining digits depend on the destination country.
This is one of the most misunderstood aspects of international trade.
Legally, the importer of record is responsible for the HS code accuracy—not the supplier, not the freight forwarder, and not customs brokers. Even if a Chinese factory provides an HS code on an invoice, the liability still rests with the importer.
That means if customs challenges a classification or applies penalties, the importer bears the consequences.
This is why professional importers treat HS code selection as a risk management task, not an administrative detail.
Misclassification rarely causes dramatic failures on day one. Instead, it creates quiet, compounding problems.
Typical issues include:
Underpaying duties and facing retroactive penalties
Overpaying duties and inflating product costs unnecessarily
Customs clearance delays due to code discrepancies
Shipment holds for missing regulatory documentation
Product bans due to restricted classifications
Many sellers only discover HS code problems after scaling their imports—when the financial impact becomes much larger.
There is no single perfect method, but a structured approach greatly reduces error.
1. Start with Product Function, Not Marketing Language
HS codes are based on what a product does and what it is made of—not how it is branded or marketed. A “smart gadget” may actually be classified as an electronic controller, a lighting device, or a communication module depending on its core function.
Break your product down into:
Primary material
Primary function
Intended use
Key components
2. Use Official Tariff Databases
Each major market maintains its own searchable tariff system:
USA: HTS (Harmonized Tariff Schedule)
EU: TARIC
UK: UK Global Tariff
Canada: Customs Tariff
These databases allow you to search by keyword or browse by chapter.
3. Compare Multiple Similar Listings
Do not rely on the first matching code you find. Review several similar product entries and compare descriptions carefully.
Look for distinctions related to:
Material differences
Power source
Usage category
Level of automation
Small technical differences can lead to completely different classifications.
4. Cross-Check with Supplier Information
Suppliers often have historical HS codes for similar exports. While these should not be blindly trusted, they can provide a useful starting reference.
Use supplier data as a comparison tool, not a final authority.
Self-classification works for simple, low-risk products. For complex or regulated goods, professional input is strongly recommended.
You should seek expert support when:
The product has electronics, batteries, or wireless functions
The product combines multiple materials or functions
The product falls into a gray regulatory area
The shipment value is high or recurring
You are entering a new market (EU, UK, etc.)
A formal HS classification opinion costs far less than a customs penalty or shipment seizure.
These terms are often used interchangeably, but they are not the same.
HS Code: The 6-digit international classification system
HTS Code: The USA’s extended version of the HS system
TARIC Code: The EU’s extended version of the HS system
UK Global Tariff Code: The UK’s national extension
The international HS code stays consistent. The national extensions differ and determine duty rates and compliance rules.
If you use DDP shipping or door-to-door logistics, HS code accuracy becomes even more critical.
Why? Because duties, VAT, and customs fees are all calculated based on the HS code. If the code is wrong, your landed cost estimate is wrong.
This can lead to:
Unexpected surcharge invoices
Margin erosion
Disputes with logistics providers
Delayed deliveries to fulfillment centers
In DDP workflows, HS codes are not just compliance data. They are financial inputs.
For sellers operating across Amazon, Shopify, and eBay, HS code consistency matters more than many realize.
If different shipments use different codes for the same product:
Customs may flag discrepancies
Duties may vary between shipments
Accounting records become inconsistent
Risk of audit increases
A best practice is to create a centralized product classification list that standardizes HS codes across all shipments and destinations.
DIDADI Logistics supports importers by reviewing HS code selections during export preparation and shipment planning.
By aligning product descriptions, commercial invoices, and shipping documents at origin, DIDADI helps reduce classification inconsistencies before goods enter international transit. This origin-side coordination improves customs clearance predictability and reduces the risk of delays or duty disputes for shipments moving to the USA, EU, and UK.
