4. What quality assurance measures and certifications should I look for when sourcing thick plexiglass internationally?

Ensure your supplier provides comprehensive quality documentation, including ISO 9001 certifications, product test reports, and compliance with regional standards (e.g., ASTM, EN, or local certifications). Request test certificates verifying impact resistance, optical clarity, UV stability, and fire safety if relevant. Suppliers should also perform incoming raw material inspections and process controls during production.

Ensure proper packaging—such as protective films, corner protectors, and reinforced pallets—to prevent damage during transit. Coordinate with customs brokers familiar with import regulations in your country, and factor in lead times for customs clearance.

Keep abreast of trade policies, currency exchange rates, and regional standards that could influence costs and compliance.
