What Is Nice Class 1?
Nice Class 1 is the first class in the Nice Classification and the home of industrial and scientific chemicals and raw materials. It covers chemicals used in industry, science, agriculture, and manufacturing; unprocessed plastics and artificial resins; chemical fertilizers and soil products; fire-extinguishing compositions; tempering and soldering preparations; tanning substances; and industrial adhesives. It is the foundational inputs class — the raw chemistry that other industries build on.
Class 1 is overwhelmingly a B2B class. Its goods are sold to manufacturers, farmers, and laboratories rather than consumers, which gives it a different character from the consumer-goods classes. The boundaries that matter most run to Class 2 (paints), Class 4 (fuels and oils), and Class 5 (pharmaceuticals) — the points where a "chemical" becomes a finished product or a medicine.
What Class 1 Covers
- Industrial and laboratory chemicals and reagents
- Unprocessed artificial resins and unprocessed plastics
- Chemical fertilizers and soil-conditioning products
- Industrial adhesives and bonding agents
- Fire-extinguishing and fire-prevention compositions
- Tempering, soldering, and metal-treatment preparations
- Tanning substances and chemicals for industry
- Chemicals for water treatment and processing
The exclusions are about finished form and purpose. Paints, pigments, and coatings are Class 2. Industrial oils, greases, and fuels are Class 4. Medicated and pharmaceutical preparations are Class 5. Adhesives for stationery or household use are Class 16. The same chemistry can land in different classes depending on whether it is a raw industrial input or a finished consumer product.
Boundary note: Adhesives are the classic split. An industrial bonding agent sold to manufacturers is Class 1, but a glue stick or household adhesive sold to consumers is Class 16. The same product chemistry can fall in either class depending on its use and market.
The Chemical Class Boundaries
Class 1 sits at the start of a chain of related classes, and accurate placement depends on how processed and how purpose-specific the product is:
- Class 1 — raw industrial chemicals and inputs: reagents, resins, fertilizers, industrial adhesives.
- Class 2 — paints, pigments, and coatings: finished color and protective products. See our Class 2 guide.
- Class 4 — fuels, oils, and lubricants.
- Class 5 — pharmaceuticals and medicated preparations. See our Class 5 guide.
A chemical manufacturer with a broad catalog often files across several of these classes, because its product range spans raw inputs, finished coatings, and specialty preparations.
Notable Brands in Class 1
- BASF — one of the largest chemical companies in the world, with a vast Class 1 portfolio
- Dow — industrial chemicals, plastics, and specialty materials
- DuPont — historically a defining name in industrial chemistry and materials
- Agricultural-input brands — fertilizer and soil-product marks central to the agribusiness sector
Filing Strategy in Chemical Categories
Chemical brand names tend to be coined or arbitrary — invented words and alphanumeric designations — which means descriptiveness refusals are less common than in consumer classes. The bigger clearance challenge is the density of similar technical names across overlapping chemical categories, and the need to file in the right class among several adjacent ones. Distinctive, coined names register most easily and are standard practice in the industry. Early, accurate filing across the relevant chemical classes is the core strategy.
Common Filing Mistakes
- Filing finished coatings in Class 1: paints and pigments are Class 2.
- Filing household glue in Class 1: consumer adhesives are Class 16.
- Filing medicated chemicals in Class 1: pharmaceutical preparations are Class 5.
- Single-class filing for a broad catalog: chemical makers often need several adjacent classes.
Frequently Asked Questions
What's the difference between Class 1 and Class 2?
Class 1 covers raw industrial and scientific chemicals — reagents, resins, fertilizers, and industrial adhesives. Class 2 covers finished paints, pigments, varnishes, and coatings. The dividing line is processing and purpose: a raw chemical input is Class 1; a finished color or protective coating is Class 2.
Are adhesives in Class 1?
Industrial adhesives and bonding agents sold to manufacturers are in Class 1. But adhesives for stationery or household use — glue sticks, household glue — are in Class 16. The same product chemistry can fall in either class depending on whether it is an industrial input or a consumer product.
Are fertilizers in Class 1?
Yes. Chemical fertilizers and soil-conditioning products are in Class 1 as agricultural chemical inputs. Living plants and natural agricultural produce, by contrast, are in Class 31, and the dividing line is that Class 1 covers the chemical input, not the plant.
Do chemical brand names face descriptiveness refusals?
Less often than consumer-goods names, because chemical brands typically use coined or arbitrary names and alphanumeric designations. The bigger clearance challenge is the density of similar technical names across overlapping categories and choosing the correct class among several adjacent chemical classes.
Search Class 1 Before You File
Chemical and industrial-input names crowd across technical categories and adjacent classes, so clearance is worthwhile even in B2B markets. Use tmarkmetric to browse registered Class 1 trademarks, see which names are taken, and search the broader registry before you commit.
