Adding HS Codes

For accurate tax calculation and smooth international shipping, every product you sell through Zelph should have customs information set. This article walks you through how to add it.

What customs information you need

Each product needs three things filled in for retailers to ship internationally:

• HS Code — The Harmonised System code that identifies what kind of product this is for customs.
• Country of Origin — Where the product was made or sourced from.
• Weight — The shipping weight per unit, with its unit (g, kg, lb, oz).

Without these, retailers may not be able to generate accurate shipping labels or duties information for customers outside their home country.

Adding customs info at the product level

The fastest way is to set the values once at the product level — they’ll cascade down to every variant.

1. Open Products in your sidebar and choose the product you want to update.
2. Scroll to the Shipping & Customs section.
3. Fill in HS Code, Country of Origin, Weight and the Weight unit.
4. Click Save.

Zelph will apply these values to every variant of the product automatically.

Overriding per variant

If a specific variant has different customs information (for example, one size weighs significantly more or a colourway is manufactured in a different country), you can override at the variant level:

1. Open the product and go to the Variants tab.
2. Click Edit next to the variant you want to change.
3. Update the HS Code, Origin Country, Weight, or Weight unit as needed.
4. Click Save changes.

Variant-level values always take priority over the product-level defaults.

Where this information is used

• International shipping labels — Carriers need HS codes and country of origin to clear customs.
• Duties and taxes — Shopify and shipping platforms use this data to estimate or charge duties accurately at checkout.
• Retailer transparency — Retailers selling your products to international customers rely on these values being correct.

💡 Tip: If you’re not sure which HS code applies to a product, the UK government’s Trade Tariff tool and the US Harmonized Tariff Schedule are good starting points.
