1.3g cakes fireworks manufacturers

1.3g fireworks are classified as Professional Grade (UN0335), containing higher amounts of flash powder and pyrotechnic composition than consumer-grade 1.4g items. Key specs include tube diameter (inner bore size), shot count, and total explosive content (NEC/NEQ). Buyers must ensure the burst height and safety radius align with their display site dimensions to prevent fire hazards.

For the US market, products must have APA (American Pyrotechnics Association) 87-1 compliance and a valid EX Number issued by the DOT. For the EU, CE Marking (Category F3 or F4) and compliance with EN 15947 are mandatory. All shipments must be accompanied by a Material Safety Data Sheet (MSDS) and a Certificate of Analysis (CoA) to verify chemical stability.

Quality is determined by the consistency of timing between shots and the vibrancy of chemical colors (e.g., strontium for red, barium for green). Request high-definition demo videos from the supplier and verify the moisture-proof packaging quality. A high-quality cake should have a reinforced base to prevent tipping during discharge and dual fuses (reserve fuse) for reliability.

Fireworks must be stored in Type-4 or Type-2 magazines that are climate-controlled to prevent humidity-induced degradation, which can lead to duds or erratic behavior. Ensure the supplier uses heavy-duty corrugated outer cartons with waterproof liners to protect the pyrotechnic composition during long-term sea transit.

Fireworks are Class 1.3G Explosives and can only be shipped via specialized hazardous materials containers (DG Containers). You must use a freight forwarder with a Dangerous Goods license. Shipping is typically restricted to full container loads (FCL); Less than Container Load (LCL) is generally not permitted for explosives due to safety regulations.

Always prioritize suppliers on Made-in-China.com who hold Audited Supplier status. Use secured payment terms and consider hiring a third-party inspection agency (like SGS or Intertek) that specializes in pyrotechnics to conduct a loading supervision, ensuring the goods packed match the certified samples.

Buyers must possess a Federal Explosives License (FEL) in the US or equivalent import permits in their respective countries. You must provide the supplier with a Letter of Authorization and ensure the Port of Discharge is equipped to handle Class 1 explosives, as not all international ports accept hazardous cargo.

Negotiate based on NEC (Net Explosive Content) weight rather than just shot count, as this determines the actual 'power' of the product. Seek volume discounts for off-season orders (typically February to May) and request customized labeling/branding which is often included for orders exceeding a 20GP container volume.
