Wholesale display show fireworks manufacturers

Professional display fireworks are categorized by UN Numbers (typically UN0333, UN0334, or UN0335) and Hazard Classes (1.1G, 1.3G, or 1.4G). Buyers must specify the shell diameter (e.g., 2.5", 3", 4", 5", 6"), burst height, and composition type. Ensure the supplier provides a Material Safety Data Sheet (MSDS) and that products comply with EN 15947 (EU) or APA Standard 87-1 (USA) for chemical stability and fuse timing.

Request video demonstrations of specific batches to verify color saturation, burst symmetry, and hang time. High-quality fireworks use pure chemical salts for vibrant colors and consistent lift charges to ensure uniform height. It is critical to verify the moisture content of the powder, as dampness leads to 'duds' or dangerous low-bursts. Prioritize suppliers who offer third-party batch testing (e.g., CIQ inspection in China).

For the US market, products must be AFSL (American Federation of Fireworks Services) tested and have DOT (Department of Transportation) EX numbers. For the European market, CE marking and Category F4 (professional use) certification are mandatory. Always verify that the manufacturer is a licensed explosives production facility with a valid Export License for Dangerous Goods.

Yes, professional suppliers can customize effect sequences, color themes (e.g., corporate branding colors), and duration. You should provide a firing script or storyboard. Note that customization usually requires a higher MOQ (Minimum Order Quantity) and a longer lead time (typically 45-60 days) to allow for specialized chemical mixing and drying processes.

Fireworks are Class 1 Explosives and cannot be shipped via standard courier or air freight. They must be transported in specialized DG (Dangerous Goods) containers via sea freight. Ensure your freight forwarder is experienced in Class 1 logistics and that the shipping line accepts explosives. You must also ensure the destination port is authorized to handle hazardous materials.

Use Secure Payment services provided by reputable platforms like Made-in-China.com to ensure funds are only released upon proof of shipment. Given the nature of the product, pre-shipment inspection by a professional agency (like SGS or CIQ) is non-negotiable to verify that the goods match the hazardous classification declared on the bill of lading.

Do not negotiate solely on the lowest unit price. Low-cost fireworks often use inferior clay plugs or recycled paper tubes, which increase the risk of tube explosions (flowerpots). Instead, negotiate based on net explosive content (NEC) and packaging durability. A slightly higher price for double-wrapped shells can significantly reduce breakage during transit.

The buyer must possess a valid Federal Explosives License (FEL) or the equivalent national permit in their country to legally import and store these goods. You must provide a Letter of Authorization and a Storage License to the supplier before the production of professional-grade (1.3G) display fireworks begins.
