PC and ABS are the two most common hard-shell plastics in luggage, and PC+ABS blends sit between them. The material choice drives impact performance, weight and price — and it also drives the compliance questions: additives, coatings, colorants and recycled content all need documentation. Neither material is "certified" as such; what matters is whether the specific compound in your shell complies with the rules of your market.
This guide compares the materials and explains what to ask a supplier.
PC and ABS luggage — safety and material compliance explained
What Is PC?
Polycarbonate is an impact-resistant, lightweight engineering plastic.
PC shells are known for flexing under impact rather than cracking, which makes them popular for premium hard-side cases. The material questions sit in the additives and coatings: what is in the compound, and what is on the surface.
What Is ABS?
ABS is a tough, economical thermoplastic.
ABS shells are stiff and rigid, with good impact strength for everyday use. ABS is widely used across mid-range luggage. Compliance questions sit in colorants, additives and, increasingly, recycled content.
What Is PC+ABS?
PC+ABS is a blend that combines polycarbonate's impact behaviour with ABS's rigidity and processability.
Many hard shells are PC+ABS rather than pure PC. Buyers should confirm the actual blend ratio, because it affects performance claims and the material documentation.
Additives and Coatings
The compound is not the whole story.
Flame retardants, plasticizers and stabilizers can be added to the resin, and the shell is usually coated or painted. Restricted substances can appear in any of these layers. Ask for the compound composition and the coating chemistry.
Recycled Materials
Recycled content is a growing part of luggage, and it changes the compliance picture.
Recycled resin can vary in composition, so chemical testing becomes more important, and environmental claims about recycled content need substantiation in markets such as the EU. If the shell uses recycled material, ask how composition is controlled and verified.
Chemical Compliance
The usual questions for plastic shells:
- Restricted substances in the resin and additives
- REACH obligations for chemicals in the compound and coating
- Children's product limits where applicable
- Coating and paint chemistry, including heavy metals

Buyer Considerations
- Confirm the actual shell material and blend ratio in the specification
- Request the material declaration and compound information
- Ask about recycled content and how it is controlled
- Request coating and paint chemical documentation
- Agree performance testing (drop, corner impact) per your contract
- For children's products, apply the children's product rules on top
FAQ
Which is better, PC or ABS?
It depends on the product position. PC tends to be lighter and more impact-resistant; ABS is more economical and rigid; PC+ABS blends the two.
Is PC or ABS "certified"?
No. Materials comply with rules or they do not; the evidence is compound, coating and testing documentation.
What compliance questions apply to plastic shells?
Restricted substances in the resin and additives, coating chemistry, recycled-content variability and children's product limits where applicable.
Does recycled ABS need more testing?
Recycled content can vary in composition, so chemical testing and composition control become more important.
What documents should I ask for?
Material declaration, compound and additive information, coating chemical reports, and test reports for the shell.
When should I choose the material?
At specification stage — the material decision affects performance, cost and compliance, so it belongs in product development.
If you are developing a new luggage collection, it is useful to discuss compliance requirements before finalizing materials, components and production specifications. CLK Luggage supports OEM/ODM luggage development and works with international buyers on product specifications, quality control and market-specific documentation.
Regulations and requirements can change. Always confirm the latest requirements with the relevant authority or a qualified compliance professional before placing an order or shipping products.
