Adding HS Codes

When shipping goods internationally, whether you’re based in Australia, selling to the European Union, the US, or anywhere else, understanding and using the correct Harmonised System (HS) codes is crucial. HS codes are standardised numerical classifications for products, enabling customs authorities and logistics providers worldwide to identify the nature of the goods, determine applicable duties, and ensure compliance with international trade regulations.

Use the links below to jump to the section you need and get step-by-step guidance on understanding and applying HS codes for international shipping.

What’s a HS Code?

An HS (Harmonised System) code is a globally recognised numeric classification for traded products, typically consisting of six to ten digits. Each code describes a specific category of goods, from clothing and electronics to automotive parts and homewares. By using the right HS code, you provide customs authorities with a universal “language” that clearly communicates what you’re shipping:

Key Benefits:

  • Global Standardisation: HS codes are used by more than 200 countries, streamlining international trade.
  • Accurate Duty and Tax Calculation: With the correct HS code, customs can determine the right tariffs, taxes, and VAT rates for your shipment.

Who Needs a HS Code?

Anyone sending goods across international borders needs to assign an HS code, this includes both businesses and individuals. Whether you're shipping a single item or running a full-scale ecommerce operation, HS codes are essential for customs clearance and compliance.

  • Online Sellers: If you sell products internationally through your own website or a marketplace.
  • Manufacturers and Wholesalers: Bulk shipments require accurate HS codes to calculate duties and ensure compliance.
  • Importers and Exporters: Any business involved in global trade, regardless of size.
  • Individuals: Even if you’re just sending a gift or personal item overseas, you still need to use the correct HS code to avoid delays or unexpected charges.

How HS Codes Work with Your E-Commerce Platforms

Your ecommerce platform might not automatically assign HS codes, but they’re essential when shipping internationally. HS codes (Harmonised System codes) are used when you:

  • Create shipping labels
  • Fill out customs forms
  • Upload product data to international marketplaces

When you book an international shipment, you’ll usually be asked to provide the HS code. Interparcel uses this information to automatically generate the commercial invoice. This helps your parcels clear international borders without delays and ensures the correct duties and taxes are applied.

If you’ve included HS codes in your product descriptions within your Shopify or WooCommerce store, they’ll automatically import into the inventory section of the Interparcel platform when syncing your products. This makes it easier to manage HS codes for all your SKUs and streamline international fulfilment.

If an HS code hasn’t been included during import or you're using another ecommerce platform, you can also manually enter it in the Interparcel inventory or directly in the shipment.

How to Find the Right HS Code

Whether you use the Shipping Calculator or the Shipping Manager on our platform, you’ll be asked to complete the Customs Invoice section. You’ll need to provide:

  • Your Tax Status
  • Reason for Export
  • Required identification numbers (varies by destination country)
  • For each product:
    • A clear, specific product description: what is it and what's made of?
    • Quantity
    • HS Code
    • Country of Manufacture
    • Value (of each item)

When booking international shipments through our platform, you can automatically generate the HS Code simply by entering a detailed description of your product. Our system uses AI and third-party platforms to suggest the most accurate code based on your input, saving you time and reducing the risk of manual errors.

That said, it's always a good idea to double-check the HS Code is correct for each country you're shipping to. While the first six digits are usually standard worldwide, countries can add up to four extra digits to classify products further, and these can differ by destination.

You can verify your HS Code using the official tools for each region:

These sites ensure your code matches local customs requirements and help prevent clearance issues or unexpected charges.

Follow these steps to select the HS Code on our platform:

  1. In the shipment details window, click the Add a product button to enter your product details, or click an existing product to edit it.
  2. Fill in the product details and click the search icon to find the correct HS Code.
  3. Enter the item name and what it’s made of, then click Search. The system will display several HS Code options. Select the one that best matches your product.
  4. Please note: Our system provides an 8-digit HS Code for most destinations. The USA, Sweden, and Spain require a 10-digit HS Code.
  5. After checkout, your commercial invoice will be generated using this information. Print three copies and attach them to your parcel along with your shipping label and any other required documents.

Additional Details and Considerations

Global Standardisation:

HS codes ensure that no matter where your package is headed, EU, North America, Asia, or beyond, customs officials have a clear understanding of what’s inside. This universal approach reduces misunderstandings and speeds up processing.

Determining Duties and Taxes:

Accurate HS codes mean accurate duty calculations. If you pick the wrong code, you risk overpaying on taxes or facing disputes at customs, potentially causing delays and extra costs.

Ensuring Compliance and Smooth Customs Clearance:

Correct HS codes are a key compliance factor. Customs officials rely on them to apply appropriate regulations, safety checks, and import controls. Getting it right minimises the chance of your shipment being held, inspected, or returned.

Keep in mind that customs authorities may open your parcel to verify its contents. If the description or HS code on your commercial invoice doesn’t match what’s inside, your shipment could be delayed, fined, or rejected. Double-checking your information helps avoid these risks.

Updating Codes for Accuracy:

Products evolve, and so do classification rules. Make sure to periodically review the HS codes for your products, especially if you modify materials, packaging, or product lines. Staying up to date helps maintain smooth operations and avoid penalties.
