The EU operates quality and origin certification schemes that can in principle apply to algae and algal products. This chapter covers the regulatory framework for Protected Designation of Origin (PDO), Protected Geographical Indication (PGI), Traditional Speciality Guaranteed (TSG), and the EU organic logo, as well as the EU Ecolabel. These schemes provide market differentiation tools for producers meeting the specified quality, origin or production standards.

The primary EU quality scheme for agricultural products and foodstuffs (including seafood and aquaculture products) is governed by:

Regulation (EU) No 1151/2012 of the European Parliament and of the Council of 21 November 2012 on quality schemes for agricultural products and foodstuffs, OJ L 343, 14.12.2012, p. 1.

Relevance to algae: This Regulation covers PDO, PGI and TSG schemes for agricultural products and foodstuffs. As noted throughout this wiki, algae are classified as agricultural products for the purposes of the CN (Chapter 12, heading 1212), which places them within the material scope of the quality schemes Regulation. Key scheme types:

• Protected Designation of Origin (PDO): reserved for products whose quality or characteristics are essentially or exclusively due to a particular geographical environment (with its inherent natural and human factors), and where all stages of production, processing and preparation take place in that geographical area.
• Protected Geographical Indication (PGI): for products where at least one stage of production, processing or preparation takes place in the specified geographical area, and whose quality, reputation or other characteristic is attributable to that area.
• Traditional Speciality Guaranteed (TSG): highlights traditional aspects of a food (production method, composition or traditional name) without requiring geographical origin.

No EU-wide PDO or PGI registrations for algae products exist as of June 2026, to the best of our knowledge. However, some national and local algae products have characteristics and reputations linked to specific geographical origins or traditional production methods that could in principle support a GI application:

• Wild-harvested seaweeds from specific coastal areas (e.g. Breton coastal seaweed, Irish Atlantic seaweed) may have distinctive characteristics attributable to the specific water quality, tidal conditions and species assemblage of their harvest area.
• Traditionally dried or processed seaweed products from specific fishing communities may have characteristics of traditional method associated with specific regions.
• Agar produced from specific Gelidium or Gracilaria species in defined coastal habitats.

A GI registration process begins with a producer group in the relevant member state applying to the national authority, which then forwards the application to the Commission for EU-level registration. The process is lengthy (several years) but provides a legally enforceable EU-wide protection against misuse of the name.

The EU organic logo (the green leaf logo) and the certification framework under Regulation (EU) 2018/848 are covered in full in Organic Production and Other Certifications. The EU organic logo is one of the most commercially significant quality marks for algae products, particularly in the supplement and food ingredient sectors.

Regulation (EU) 2017/1001 of the European Parliament and of the Council of 14 June 2017 on the European Union trade mark, OJ L 154, 16.6.2017, p. 1. EUR-Lex

Relevance to algae: The EU Trade Mark (EUTM) is a unitary trade mark right valid across all EU member states, registered through EUIPO (EU Intellectual Property Office). Unlike PDO/PGI (which protect geographical names for communities of producers), an EUTM protects a specific brand or mark belonging to its owner. Algae companies protecting brand names, logos, and product names used in EU markets should consider EU trade mark registration alongside national trade mark protections. EUTMs provide cost-effective EU-wide protection (one registration covering all member states) and are increasingly important as algae brands expand cross-border.

Regulation (EC) No 66/2010 of the European Parliament and of the Council of 25 November 2009 on the EU Ecolabel, OJ L 27, 30.1.2010, p. 1.

Relevance to algae: The EU Ecolabel (“flower” logo) is a voluntary environmental certification applicable to a range of product categories. Product group criteria have been established for several categories relevant to algae producers, including:

• Cosmetics (rinse-off products) — relevant to seaweed-based shampoos and shower products.
• Textiles — relevant to algae-fibre-containing textile products.
• Growing media and soil improvers — potentially relevant to algae-based horticultural growing media.

Ecolabel criteria focus on reduced environmental impact across the lifecycle; algae products typically perform well on biodegradability and land-use criteria. However, criteria for specific algae product categories may not yet exist or may be under development.

• PDO/PGI is worth considering for wild-harvested seaweed products with distinctive geographical characteristics, particularly where there is a community of producers from a specific coastal area willing to jointly apply for registration.
• TSG registration could be relevant for traditionally processed algae products (e.g. dried kelp from specific communities) even without a specific geographical link.
• EU Trade Mark registration is the most immediately accessible and commercially relevant intellectual property tool for most algae brands; register key brand names through EUIPO.
• EU Ecolabel provides market recognition in specific product categories; check whether criteria exist for your specific product type.
• Organic certification under Regulation (EU) 2018/848 is commercially the most significant quality mark for the algae food and supplement sector — see Organic Production and Other Certifications.
