Manufacturer and brand

From December 13, 2024, the GPSR regulation requires manufacturer data on the product page. Polski for WooCommerce lets you add manufacturer data, brand and GTIN/EAN number to each product.

GPSR requirements

According to Regulation (EU) 2023/988 (GPSR), the product page must include:

manufacturer or importer name
manufacturer postal address
email address or website for contact
for products from outside the EU - data of the responsible person in the EU

This information must be easily accessible to the consumer before purchase.

Configuration

Enabling the module

Go to WooCommerce > Settings > Polski > Manufacturer and activate the module. After activation, new fields will appear in the product editor.

Manufacturer data (GPSR)

In the product editor, in the “Polski” tab or in the side panel, you will find the “Manufacturer (GPSR)” section:

Field	Required	Description
Manufacturer name	Yes	Full manufacturer company name
Address	Yes	Street, number, postal code, city, country
Email	Yes*	Contact email address
Website	Yes*	Manufacturer website URL
EU responsible person	Conditional	Required for products from outside the EU
Responsible person address	Conditional	Full address of the responsible person

*At least one electronic contact method is required (email or website).

Global manufacturer data

If you mainly sell your own brand products, you can set default manufacturer data in WooCommerce > Settings > Polski > Manufacturer. This data will be automatically applied to all products that do not have individual manufacturer data assigned.

Brand taxonomy

The plugin registers a polski_brand taxonomy for managing product brands.

Managing brands

Go to Products > Brands to create and edit brands. Each brand can contain:

name
slug (URL identifier)
description
logo (taxonomy thumbnail)

Assigning a brand to a product

In the product editor, in the side panel, you will find a “Brand” metabox - select a brand from the list or add a new one.

Brand pages

The plugin automatically generates archive pages for each brand. Customers can browse all products of a given brand at:

/brand/brand-name/

The archive slug can be changed in plugin settings.

GTIN/EAN

The plugin adds a field for product identification numbers compliant with GS1 standards.

Supported formats

Format	Length	Application
EAN-13	13 digits	European standard
EAN-8	8 digits	Small packages
UPC-A	12 digits	American standard
GTIN-14	14 digits	Bulk packaging
ISBN-13	13 digits	Books

Validation

The plugin automatically validates GTIN/EAN number correctness (check digit). An invalid number will be rejected with an error message.

Structured data (Schema.org)

The GTIN number is automatically added to the product structured data (JSON-LD), which improves visibility in Google search results:

{
    "@type": "Product",
    "gtin13": "5901234123457",
    "brand": {
        "@type": "Brand",
        "name": "Brand Name"
    },
    "manufacturer": {
        "@type": "Organization",
        "name": "Manufacturer Name",
        "address": "ul. Przykladowa 1, 00-001 Warsaw"
    }
}

Shortcode

Use the shortcode [polski_manufacturer] to display manufacturer data anywhere.

Common issues

Manufacturer data does not display on the product page

Check that the manufacturer module is enabled
Make sure the product has filled data or default data is configured
Verify that the theme supports the woocommerce_single_product_summary or woocommerce_product_meta_end hook

GTIN rejected as invalid

Check the GTIN number check digit. Use the GS1 calculator for verification: https://www.gs1.org/services/check-digit-calculator

Brand does not appear in Schema.org

Make sure the brand is assigned to the product through the polski_brand taxonomy, not just entered in the manufacturer text field.
