Trademark applications and registrations in Class 1 over the past 15 years.
Class 1 encompasses chemicals used in industry, science, photography, agriculture, horticulture, and forestry, along with unprocessed artificial resins, unprocessed plastics, fire extinguishing compositions, tempering and soldering preparations, and adhesives for industrial use. With over 75,800 live marks on the USPTO register, the class reflects the breadth of the chemical and materials science industries, from multinational conglomerates to specialized agricultural suppliers.
The class's leading filers — Fross Zelnick Lehrman & Zissu, Dennemeyer & Associates, and Sughrue Mion — represent a mix of major IP prosecution firms and global chemical manufacturers. Their presence underscores the international character of Class 1 filings, as chemical products frequently cross borders and require coordinated trademark portfolios across multiple jurisdictions.
The most persistent classification pitfall in Class 1 is the boundary with Class 5. Chemicals for industrial or agricultural use belong in Class 1; chemicals for medical or therapeutic purposes belong in Class 5. A disinfectant for industrial surface cleaning is Class 1, but a disinfectant for medical hygiene is Class 5. Similarly, adhesives for industrial manufacturing are Class 1, while adhesives for household or stationery use fall under Class 16. Unprocessed plastics in powder or liquid form are Class 1, but semi-processed plastics in extruded form for manufacturing belong in Class 17.
Chemical companies frequently adopt multi-class filing strategies spanning Classes 1, 2, and 17 to cover the full lifecycle of their products from raw materials through coatings and processed forms. Agricultural brands often pair Class 1 with Class 31 for natural agricultural products or Class 44 for agricultural services. Understanding these boundaries is essential, as the highly technical nature of the goods makes reclassification requests from examining attorneys particularly common.
Class 1 includes mainly chemical products for use in industry, science and agriculture, including those which go to the making of products belonging to other classes.

Search TrademarksClass 1 covers chemicals for industrial, scientific, and agricultural use, while Class 5 covers pharmaceutical and medical preparations. If a chemical is used for medical treatment or health purposes, it belongs in Class 5. If it is used in manufacturing, research, or farming, it falls under Class 1.
No. Class 1 covers adhesives for industrial use only. Household adhesives, such as glue sticks for crafts or general-purpose glue for home repairs, are classified in Class 16 (stationery adhesives) or Class 17 (sealing/insulating adhesives).
No. Cleaning chemicals for household or personal use belong in Class 3. Class 1 is reserved for chemicals used in industrial processes, scientific research, agriculture, and manufacturing.
Yes. Fertilizers, compost, manures, and soil conditioners for agricultural and horticultural use are properly classified in Class 1.
Water purification and treatment chemicals for industrial or municipal use belong in Class 1. However, water purification tablets marketed for personal health or medical use would fall under Class 5.
Unprocessed epoxy resins in liquid or powder form belong in Class 1. Once the resin is semi-processed or extruded into sheets, rods, or other manufactured forms, it moves to Class 17.
Yes. If your chemical product has both industrial and medical applications, you should file in both classes with appropriately tailored goods descriptions. The USPTO will not allow a single class to cover both uses.
Yes. Unprocessed photopolymer resins sold as raw materials for 3D printing are properly classified in Class 1. The 3D printer itself would be in Class 7, and finished 3D-printed products would be classified by their function.
The chemical compositions and agents used in fire extinguishing belong in Class 1. The fire extinguisher device itself — the apparatus — belongs in Class 9. Brands selling both the chemical and the device need filings in both classes.
The most common mistake is using language that implies a consumer end-use, such as "adhesive for home repairs" or "cleaning chemical." Class 1 is strictly for industrial, scientific, and agricultural applications. Consumer-facing language will trigger an office action requiring reclassification to Class 3, 5, or 16.
