How We Ship Soda CO2 Cartridges from China – What Buyers Should Know
When importing soda CO2 cartridges, the biggest challenge isn’t product cost — it’s logistics.
As pressurized containers, these cartridges are classified as dangerous goods, which means your shipping process must follow specific rules.
But that doesn’t have to be complicated. Here’s how we make soda cartridge shipping smooth, safe, and cost-efficient:
1. Understand the Transport Classification
All soda CO2 cartridges fall under UN1013 Class 2.2 (non-flammable gas).
This affects how they’re:
Labeled on the outer cartons
Packed inside DG-rated export boxes
Declared for air or sea freight
Handled during customs inspection
We prepare all required documents for you — including MSDS, carton UN markings, and IMDG declarations.
2. Packaging Is Designed for Safe Transit and Shelf Appeal
Because soda cartridges are often resold in kits or gift boxes, we take extra steps to protect both product and presentation:
Cartons reinforced for stacking without deformation
Moisture-resistant inner box options for long-haul ocean freight
Clean, professional packaging — no oil, rust, or broken seals on arrival
If you’re selling under your own brand, how it arrives matters as much as what’s inside.
3. Choose the Right Shipping Model
Depending on your experience and volume, we offer:
DDP (Delivered Duty Paid) — best for new importers who want a hands-off process
CIF — cost-effective if you have a local customs agent
FOB — ideal for experienced buyers using their own freight network
We work with licensed DG freight forwarders who specialize in pressurized goods, and we pre-arrange all port compliance details to minimize delays.

Which Brands Are Known for Soda CO2 Cartridges?
1. International Consumer Brands
2. OEM-Based Private Labels
3. Fast-Growing DTC or Regional Brands
(We’ve compiled detailed specs, country of origin, OEM source regions, and packaging breakdowns.)
Why isn’t my CO2 cylinder working properly with a soda maker?
Many users experience issues like the CO2 cartridge not fitting, not releasing gas, or giving inconsistent carbonation. Here are the top 3 reasons:
Thread mismatch – Not all soda makers use the same screw type
Low pressure or leakage – Often caused by poor sealing or underfilled gas
Inconsistent fizz – May be due to temperature, machine condition, or cartridge quality
What Factors Impact Soda CO2 Cartridge Quality?
Not all CO2 cartridges are created equal — especially when it comes to carbonating beverages safely and consistently. For soda applications, your customers expect clean taste, stable performance, and flawless compatibility. Here’s what experienced buyers check before placing bulk orders:
1. Internal Cleanliness = Clean Soda Taste
2. Food-Grade CO2 = Certified for Consumption
3. Leak-Proof Threading = Machine Safety
4. Burst Resistance = Shipping & Storage Security
5. Anti-Rust Finish = Longer Shelf Life in Kitchen Conditions
6. Packaging Strength = Protection from Transit Damage
Bottom line: If you’re selling soda-grade CO2, small quality flaws can lead to big brand damage. That’s why we don’t just “sell cartridges” — we engineer them for safety, taste, and long-term trust.
Safe Storage Matters for Soda CO2 Cartridges — Especially in Food-Grade Environments
Unlike industrial CO2 cartridges, soda cartridges are designed for food-related applications — often used in home kitchens, restaurants, or cafés.
That means storage isn’t just about safety — it’s also about cleanliness, packaging integrity, and brand presentation.
Here’s what you need to know when storing soda CO2 cartridges in wholesale or distribution settings:
1. Comply with Dangerous Goods Storage Requirements
Although small in size, CO2 cartridges are pressurized and classified as UN1013 Class 2.2 dangerous goods. Warehouses should meet basic DG storage conditions — such as proper labeling, no heat exposure, and restricted fire zones.
2. Keep Packaging Clean for Food-Grade Use
Soda cartridges are often placed directly into home-use siphons or used in commercial beverage preparation. To ensure hygiene and customer satisfaction:
Avoid humid or dusty storage areas
Keep outer cartons off the floor and away from condensation
Handle sealed boxes with gloves or clean hands to prevent stains on printed packaging
Even minor packaging damage or stains can reduce perceived product quality — especially in retail or gift pack scenarios.
3. Protect Brand Appearance During Transit & Shelf Storage
Retailers and distributors care not only about safety but also about how your product looks on arrival. Deformed boxes, discolored labels, or visible corrosion can hurt your brand reputation — even if the gas inside is perfectly fine.
Use the FIFO method to rotate stock and reduce shelf time, and avoid stacking cartons under high pressure to preserve shape.

Why Soda Needs CO2 Cartridges – From a Technical & Practical View
1. CO2 Is Essential for Carbonation
Soda is defined by its fizz — and that fizz comes from forcing CO2 into water under pressure. This isn’t optional or decorative — CO2 is the defining element of soda. No CO2, no soda.
2. Cartridges Are the Safest and Most Efficient Delivery System
In small soda makers (like home countertop units or handheld siphons), large refillable tanks are not practical. Cartridges offer:
Pre-measured doses (8g / 12g)
Sealed gas with no refilling required
Easy installation and single-use safety
Stable shelf life and low storage risk
These features make them ideal for consumer-level, personal, or portable soda systems.
3. Consistency Depends on Cartridge Quality
Poor quality CO2 cartridges can cause:
Weak carbonation (if gas fill is too low)
Off-flavors (if gas isn’t food-grade)
Machine failure or leaks (if thread isn’t precise or seal isn’t tight)
This means the performance of the entire soda system depends on the cartridge — it’s not just an accessory, it’s the engine behind every bottle of fizz.
4. Why OEM or Private Label Buyers Should Care
If you’re building a soda product or refill program, the quality of your cartridge determines:
End-user satisfaction
Product returns or complaints
Brand credibility
Repeat purchase rate
That’s why serious soda brands don’t cut corners on the cartridge. They choose tested, certified, soda-compatible models — like ours.
Soda CO2 cartridges are not optional. They’re essential.
They must be safe, compatible, and consistent — otherwise, the soda experience fails before it starts.

1. Soda Siphons
✔ Standard 8g compatibility✔ Easy to brand & bundle with cartridges✔ Often sold as complete kits
2. PET Bottle Carbonation Kits (with adapters)

CO2 Cartridges vs. 0.6L Aluminum Cylinders — Two Paths to Sparkling Water
If you’re in the soda business, your choice of gas system defines your product strategy.
Most solutions fall into two categories:
CO2 cartridges (8g / 12g), typically used in soda siphons and portable kits
0.6L aluminum cylinders (432g), commonly used in home soda machines like SodaStream
Both formats deliver food-grade CO2, but they serve different users and require different handling from logistics to end use.
Usage Format & Product Experience
CO2 cartridges are designed for simplicity — they’re disposable, lightweight, and don’t require refilling infrastructure.
This makes them ideal for entry-level products, trial kits, and mobile soda applications.
In contrast, 0.6L cylinders are refillable and built for long-term use. They offer much larger gas volume per unit, making them a better choice for high-frequency soda drinkers and households that use countertop machines regularly.
Market Positioning: Who Buys What?
CO2 cartridges are most popular among:
First-time users
Gift box or starter kit customers
DTC soda brands targeting portability or one-time use
Emerging markets with limited refill infrastructure
On the other hand, 0.6L aluminum cylinders are preferred by:
Families or offices making soda daily
Retail customers who already own refillable soda machines
Distributors in countries with gas exchange systems
Put simply: cartridges offer mobility and flexibility, while aluminum cylinders offer longevity and refill efficiency.
Export Logistics: What You Should Know
CO2 cartridges are classified as pressurized dangerous goods (UN1013) and require special handling and documentation for export.
They are shipped fully filled in sealed cartons and must comply with IMDG, IATA, or ADR regulations.
Aluminum cylinders, however, are typically shipped empty and filled locally by gas distributors. This allows for non-hazardous goods classification and helps reduce shipping costs, customs clearance time, and risk.
Need a Refillable Cylinder Solution?
If you’re building a refillable soda system or serving users with home carbonation machines, our aluminum cylinder line under the AlizeeCyl brand offers a clean, compatible, and export-ready option.
We supply 0.6L (432g) aluminum CO2 cylinders, commonly used in SodaStream-style devices and retail gas exchange programs.
All cylinders are:
CE / ISO certified
Shipped empty (non-DG), ready for local filling
OEM-customizable with your logo, sleeve, or color finish
Protected with foam or shrink-wrap for clean retail presentation
Let us help you build a long-term, refillable soda ecosystem — with packaging and compliance designed for global markets.

- It extends open-bottle shelf life for days — sometimes weeks
- Wine-by-the-glass dispensers in restaurants
- Home wine savers (handheld injection units)
- High-end wine cellars and tasting kits
✔ Preserves quality without chemicals✔ Popular with boutique wine shops and glass-pour bars✔ Refillable and recyclable tank options available
