Cake fireworks are categorized using two different specification systems, depending on the country and application:
Most international buyers—including Europe, South America, Asia, and professional U.S. buyers—use tube diameter (inches) to measure cake fireworks.
| Tube Size | Metric (mm) | Application |
|---|---|---|
| 0.75 inch | 18–20 mm | Small cakes, rapid-fire cakes |
| 1.0 inch | 25 mm | Standard consumer cakes, most 16–25 shots |
| 1.2 inch | 30 mm | Higher performance, louder bursts |
| 1.5 inch | 38 mm | Professional-style cakes, large effects |
| 1.75 inch | 45 mm | Premium cakes, strongest consumer effects |
-
Determines effect size & burst diameter
-
Indicates tube strength & powder capacity
-
Helps buyers compare products across suppliers
-
Matches customers’ performance expectations
-
1.0" 16 Shot Peony Cake
-
1.2" 25 Shot Brocade Crown Cake
-
1.5" Fan Shape 49 Shot Cake
-
1.75" Premium Finale Cake
This is the most accurate and professional way to specify cake fireworks.
In the United States, retail fireworks follow CPSC regulations, so cake fireworks are grouped by total powder weight.
| Category | Limit | Usage |
|---|---|---|
| 200g Cakes | ≤ 200 grams total powder | Small, fast retail cakes |
| 350g Cakes | 200–350 grams | Mid-level performance |
| 500g Cakes (Maximum Load) | ≤ 500 grams | Largest legal consumer cakes |
-
Powder weight is regulated by law
-
Retail stores organize shelves by gram class
-
Helps determine consumer safety level
-
Influences shipping and packaging rules
-
200g 25 Shot Color Cake
-
350g Z-Shape Silver Tail Cake
-
500g Maximum Load Multi-Effect Cake
Gram classification is mainly for compliance and retail marketing in the U.S.
Although they describe the same product, they focus on different aspects:
| Tube Size (Inches) | Powder Weight (Grams) | Notes |
|---|---|---|
| Describes performance & effect size | Describes legal class & safety limits | Both are useful |
| Used internationally | Used mainly in the U.S. | |
| Focus on tube diameter | Focus on total powder | |
| Important for product description | Important for regulatory labeling |
A cake described as:
-
1.2" 25 Shot Fan Shape Cake
Usually belongs to: -
350g or 500g class, depending on powder load.
A cake described as:
-
500g Maximum Load Cake
Usually uses 1.2"–1.5" tubes.
Use tube size (inch) + shot count
→ Helps understand performance level
Use gram class + effects
→ Must comply with CPSC and DOT rules
Best practice is to show both:
(Professional, international readability)
(Compliance & marketing value)
Example 1:
1.2" 25 Shot Fan Shape Brocade Crown Cake (500g Maximum Load)
Example 2:
1.0" 16 Shot Color Peony Cake (200g Class)
Example 3:
1.5" 49 Shot Z-Shape Silver Tail Cake (500g Category)
Example 4:
0.8" 100 Shot Rapid Fire Cake (200g Class)
Both specification systems are correct—just used for different purposes.
→ Best for international buyers, performance evaluation, and professional product descriptions.
→ Required for U.S. regulatory classification (200g / 350g / 500g).
The most professional approach is to include BOTH in product introductions, allowing global customers to understand performance and compliance simultaneously.
