Making It for Someone Else vs. Selling Your Own
Nice Class 40 covers the treatment and transformation of materials performed as a service for others: custom and contract manufacturing, printing services, recycling and waste treatment, metal and material processing, textile treatment and dyeing, food and drink preservation, energy production, and 3D printing. The defining principle, and the source of most confusion, is that Class 40 covers doing the work for someone else — not selling the resulting goods as your own product.
| Scenario | Class |
|---|---|
| Printing t-shirts to a customer's order | 40 (service) |
| Selling your own designed t-shirts | 25 (goods) |
| Manufacturing electronics for a client brand | 40 (service) |
| Selling your own branded electronics | 9 (goods) |
| Design and engineering of a product | 42 (service) |
| Repair and installation | 37 (service) |
The same factory can implicate two rows of that table at once: a contract manufacturer provides a Class 40 service, while a manufacturer selling its own branded goods files in the relevant product class instead. Many businesses do both and need both registrations. A print-on-demand company is the cleanest illustration — the printing service is Class 40, the blank apparel it prints on is a goods class, and the online ordering platform may be Class 35 or Class 42.
Newer categories have crowded in fast: 3D printing and additive manufacturing as a service fall squarely in Class 40. Recycling and circular-economy processing — turning waste into reusable material for clients — is a fast-growing category driven by sustainability demand. And energy generation, including renewable-energy production, is classified here too. What was once a quiet industrial class has picked up a wave of fresh filings from all three directions.
Common Filing Mistakes
The most frequent error is filing own-brand goods in Class 40 when they belong in their product class instead — Class 40 is for treatment performed for others, full stop. A close second is confusing manufacturing with design: architecture, engineering, and product design belong in Class 42, not Class 40. Makers who also sell their own products often forget they need the goods class in addition to the service class, and vague service descriptions — rather than specifying the treatment or manufacturing service precisely — routinely trigger office actions.
Quick answers: manufacturing as a service for others is Class 40, but making your own branded products to sell belongs in the class of those products; a business doing both needs both. Custom printing and print-on-demand production is Class 40, while the blank goods and the ordering platform sit in their own classes. Recycling and waste treatment performed as a service is Class 40. And the split with Class 42 is straightforward — Class 40 is physical treatment and transformation, Class 42 is design, engineering, and software.
Manufacturing, printing, and processing service names overlap with goods and design classes, so clearance should span Class 40 and its neighbors. Use tmarkmetric to browse registered Class 40 trademarks and search the broader registry before you commit. Decide whether you need the goods class alongside the service class up front. The printed-goods side connects to our Class 16 guide, and the ordering and retail side to our Class 35 guide.
