Roman candle firework

When sourcing Roman Candles, you must prioritize UN Number classification (typically UN0336 or UN0337) and Hazard Class (1.4G or 1.4S). Ensure the products comply with EN 15947 (European Standard) or APA Standard 87-1 (U.S. Standard). Key technical details include the inner tube diameter (bore size), which determines the shot height, and the chemical composition of the pyrotechnic stars to ensure color stability and smoke reduction. Always verify that the fuse burn time is between 3 to 8 seconds to allow for safe ignition distance.

Request a Batch Test Report and a Certificate of Analysis (CoA) for the gunpowder and chemical agents used. Professional suppliers on Made-in-China.com should provide high-speed camera video demonstrations of the product's firing sequence, showing consistent burst height, color intensity, and timing intervals. For large orders, it is highly recommended to hire a third-party inspection agency (like SGS or BV) to perform a 'Drop Test' and 'Thermal Stability Test' at the factory before shipment.

Roman Candles are primarily used for large-scale event displays, wedding celebrations, and retail distribution. Functional requirements vary: professional display grade candles require precise timing and high-altitude bursts (up to 30-50 meters), while consumer-grade products focus on safety and ease of use. Ensure the base or spike design is robust enough to prevent tipping during discharge, which is a critical safety function.

Fireworks are classified as Class 1 Explosives, meaning they cannot be shipped via standard air freight or LCL (Less than Container Load). They must be transported in dedicated 20ft or 40ft HQ Dangerous Goods (DG) containers. You must ensure the supplier provides a 'Container Packing Certificate' and that the shipping line accepts Class 1.4 cargo. Always confirm the port of discharge has the necessary licenses to handle explosive materials.

Use Made-in-China.com's Secured Trading Services to protect your payment. Negotiate a payment structure such as 30% deposit and 70% upon presentation of the Bill of Lading and Export License. Given the seasonal nature of fireworks, include a penalty clause for delivery delays in the contract, as missing a holiday window (like New Year or Independence Day) can render the inventory unsellable for a year.

You must possess a Federal Explosives License (FEL) or a local equivalent import permit in your country. The supplier must provide the Material Safety Data Sheet (MSDS), the EX Number (for the U.S. market), and a CE Certificate (for the EU market). Failure to provide these documents will result in customs seizure and heavy fines at the border.
