Single tube firework

Buyers must focus on the inner diameter (caliber) and powder weight (NEC - Net Explosive Content). For single tube fireworks, the caliber typically ranges from 0.8 inch to 3 inches for consumer/professional use. Ensure the tube material is made of high-quality reinforced paper or fiberglass to prevent bursting. The base stability is critical; it must be wide enough to prevent tipping during discharge.

Compliance is non-negotiable. For the US market, products must meet CPSC (Consumer Product Safety Commission) requirements and have AFSL (American Fireworks Standards Laboratory) testing. For the European market, CE Marking (EN 15947) is mandatory, classifying products into Category F1 to F4 based on hazard level. Always verify the UN Number (usually UN0336 for 1.4G or UN0335 for 1.3G) for transport compliance.

Request high-definition video demonstrations of the specific batch. Look for color purity, burst symmetry, and hang time of the stars. Professional suppliers should provide a technical data sheet detailing the effect (e.g., Peony, Chrysanthemum, or Brocade) and the altitude (height) the shell reaches, which should be consistent across the order.

Fireworks are highly sensitive to humidity. Ensure the supplier uses moisture-proof inner plastic lining and 5-layer corrugated export cartons. The packaging must be marked with Hazard Class 1.4G or 1.3G labels. For long-term storage, products must be kept in a cool, dry, and ventilated environment with a temperature below 35°C.

Fireworks are classified as Dangerous Goods (DG). They cannot be shipped via standard courier or air freight. You must use specialized DG containers via sea freight. Ensure your freight forwarder has a Dangerous Goods Declaration and that the shipping line accepts Class 1 explosives. Shipping costs are significantly higher than general cargo, often requiring a full container load (FCL).

Use secured payment terms and prioritize suppliers on Made-in-China.com who have undergone audited supplier verification. Request a Pre-shipment Inspection (PSI) by a third party like SGS or Intertek to verify the chemical composition and safety fuse timing (which should be between 3 to 8 seconds for consumer safety).

You must possess a valid Import License for Explosives in your destination country. Required documents usually include the Material Safety Data Sheet (MSDS), Certificate of Analysis (COA), Packing List, and the Competent Authority Document (CAD) for transport. Failure to provide these will lead to seizure of goods and heavy fines.

MOQs for fireworks are usually high due to production safety setups, often starting at 50-100 cartons per SKU. When negotiating, focus on the total weight of the shipment rather than just unit price. Ask for volume-based discounts if you can consolidate different effects into one container to optimize freight-per-unit costs.
