Class 17 is one of the smaller, technical goods classes: it covers rubber, gutta-percha and gum, semi-finished goods made from these materials, and sealing, packing and insulating materials. The EUIPO register holds 66,268 trademarks in Class 17, of which 38,574 are registered (as of July 2026, EUIPO register data). Growth is moderate: new registrations rose from 2,777 in 2020 to 3,015 in 2024, a 9 percent increase, with another 2,907 added in 2025. The top filers reveal who actually uses this class: not rubber companies, but the insulation and construction chemicals industry. According to EUIPO register data, Brillux leads with 179 trademarks, ahead of Henkel with 172, followed by the insulation manufacturers Kingspan (122), Rockwool (111) and Ursa (105). In practice, Class 17 is the insulation class of the construction sector. Fittingly, it keeps things sober: 59 percent of its trademarks are word marks, so the name matters more than the logo here.
What belongs in Class 17?
Class 17 covers rubber, gutta-percha, gum, asbestos and mica as raw materials, goods made from them in semi-finished form, and plastics in extruded form for use in manufacture. The part that matters most in practice: sealing, packing and insulating materials, meaning insulation boards, gaskets, insulating tape and foams, plus flexible pipes, tubes and hoses not of metal. For the boundaries: finished construction products such as rigid pipes for building or building panels belong in Class 19, chemical raw materials and industrial adhesives in Class 1, metal goods in Class 6.

Word mark or figurative mark?
Often combined with
Class 17 is rarely filed on its own: in practice it is most often combined with Class 19 (non-metallic building materials), Class 1 (chemical products) and Class 6 (metal goods), because product lines in construction and industry almost always go beyond pure insulation goods. Check before filing which class your finished product actually falls into, and remember that the list of goods cannot be extended later. If your name is distinctive, go for a word mark: at 59 percent, that is the norm in Class 17. And search the register first, because Brillux, Henkel, Kingspan, Rockwool and Ursa are all very active industrial filers here.
Common mistakes with Class 17
The most common mistake in Class 17 is the boundary question: it protects semi-finished goods and insulating materials, not the finished end product. A rubber product is classified by its purpose, so tyres fall under Class 12 and rigid construction pipes under Class 19. File only Class 17 and your actual product may not be covered at all. Second mistake: thinking too narrowly about your range. Many manufacturers sell construction products (Class 19) or chemical precursors (Class 1) alongside insulation and sealing materials, which is exactly why those are the typical neighbouring classes. Third, the name itself: descriptive elements like Iso, Therm or Flex are everywhere in this technical sector, and a name that merely describes the function is barely protectable as a word mark.

Frequently Asked Questions
What belongs in Nice Class 17?
Class 17 covers rubber, gutta-percha, gum, asbestos and mica, semi-finished goods made from these materials, and sealing, packing and insulating materials, plus flexible pipes, tubes and hoses not of metal. Finished products are classified by their purpose instead: rigid construction pipes belong in Class 19, tyres in Class 12.
Why do insulation manufacturers file the most trademarks in Class 17?
Because insulating materials are the most important part of the class in practice. According to EUIPO register data (as of July 2026), the top filers are Brillux with 179 and Henkel with 172 trademarks, followed by the insulation manufacturers Kingspan (122), Rockwool (111) and Ursa (105). Class 17 is first and foremost a class for construction and industrial suppliers.
How do I tell Class 17 and Class 19 apart?
Class 17 protects insulating, sealing and packing materials plus semi-finished goods, while Class 19 covers non-metallic building materials as finished construction products, such as rigid pipes for building. If you sell insulation and building panels under one brand, you usually need both. It is no coincidence that Class 19 is the most frequent companion class to Class 17.
Which classes are typically combined with Class 17?
Most often Class 19 for non-metallic building materials, Class 1 for chemical products and precursors, and Class 6 for metal goods. A maker of sealing and insulation systems covers the typical product range with 17, 19 and 1, adding Class 6 when metal versions are involved.
