Aerosol Can Buyers FAQ: MOQ, Coating, Pressure, Samples & Lead Time
If you're sourcing aerosol cans for the first time — or switching suppliers — the same questions always come up. Below are the answers our engineering and sales teams give buyers every week, organized around the five topics that matter most: MOQ, coating, pressure, samples, and lead time.
1. MOQ — What's the Minimum Order?
Short answer: It depends on the material and customization level.
Product Type | Typical MOQ |
|---|---|
Stock/plain aluminum cans | 5,000 pcs |
Custom-printed aluminum (monobloc) | 10,000–20,000 pcs |
Stock tinplate aerosol cans | 10,000 pcs |
Custom-printed tinplate cans | 20,000 pcs |
Cones & domes (stock sizes) | 20,000 pcs |
Cones & domes (custom sizes) | 50,000 pcs |
Chemical tin cans (open-top) | 3,000–5,000 pcs |
Why the difference? Tooling, printing plate setup, and coating-line minimum runs drive MOQ. Aluminum monobloc requires impact extrusion tooling per diameter; tinplate printing needs plate making per design. We keep MOQs as low as possible, but below certain volumes the unit cost rises sharply due to setup amortization.
Tip for new brands: Start with a stock-size plain can + sticker label to test the market, then move to printed cans once demand is proven.
2. Coating — How Do I Choose the Right Internal Lining?
The internal coating is the single most important decision for product safety and shelf life. Here's how we guide buyers:
Step 1 — Tell us your formulation:
Solvent-based (LPG, DME, propane, butane)?
Water-based (alcohol, glycol, saline)?
Oil-based (edible oil, lubricant, silicone)?
Acidic (pH < 5) or high-polyphenol?
Food-contact or pharmaceutical?
Step 2 — We match the lining:
Formulation Type | Recommended Coating |
|---|---|
LPG/DME propellants, hydrocarbons | Epoxy-Phenolic |
Water-based, saline, nasal sprays | PAM (Phenolic-Alkyd-Modified) |
Edible oils, cooking sprays | Food-Grade Epoxy, PAM |
Aggressive solvents (MEK, acetone) | Epoxy-Phenolic (heavy grade) |
Food-contact with BPA restrictions | BPA-NI formulations |
Pharma/oral/nasal | Pharma-grade certified coatings |
Step 3 — Compatibility testing (optional but recommended):
We fill sample cans with your actual product and conduct accelerated aging (temperature cycling, pressure hold). If the lining holds, we proceed. If not, we adjust.
Common mistake: Buyers assume "epoxy" covers everything. It doesn't. A lining that works perfectly for hair spray can fail catastrophically with olive oil or MEK-based adhesive.
3. Pressure — What Ratings Do You Support?
Aerosol cans are pressure vessels. Getting this wrong is a safety hazard.
Standard pressure ratings:
Can Type | Burst Pressure | Working Pressure (typical) |
|---|---|---|
Aluminum monobloc (22–53 mm) | 18–25 bar | 8–12 bar |
Tinplate aerosol can | 15–20 bar | 6–10 bar |
Chemical tin can (non-pressurized) | N/A | Vacuum or ambient only |
Key variables we check with every buyer:
Propellant type and fill ratio
Filling temperature (affects vapor pressure)
Maximum expected storage temperature (container ships in summer = 60–70°C)
Valve pressure rating
Our process: We calculate the worst-case internal pressure at 60°C and ensure the can's burst rating has a minimum 2× safety factor. If your formulation pushes limits, we recommend either a thicker wall, a smaller diameter (stronger hoop strength), or a different material.
Don't guess. If you're unsure about your product's pressure profile, send us your formulation and filling parameters — we'll do the calculation.
4. Samples — How Do I Get Them?
Sample policy:
Sample Type | Cost | Lead Time |
|---|---|---|
Stock plain cans (no print) | Free (you pay shipping) | 3–5 days |
Custom-printed samples | $50–200 (refundable against order) | 10–15 days |
Lined sample cans for compatibility test | Free with formulation disclosure | 7–10 days |
Full prototype with valve + actuator | $100–300 (refundable) | 15–20 days |
How to request samples effectively:
Tell us the can diameter and capacity you need
Share your product type (even a general description helps)
Specify if you need food-grade or chemical-grade lining
Confirm if you need matching valves/caps or just the empty can
We ship samples via DHL, FedEx, or UPS. For buyers in Asia, we can often hand-deliver during trade show visits.
5. Lead Time — When Will My Order Be Ready?
Standard lead times (after artwork/sample approval):
Stage | Duration |
|---|---|
Tooling (new diameters only) | 10–15 days |
Coating application | 3–5 days |
Printing | 5–7 days |
Can body forming | 3–5 days |
Quality inspection & packing | 2–3 days |
Total (standard reorder) | 25–35 days |
Total (first order, custom print) | 30–40 days |
What can speed things up:
Using stock diameters and heights
Providing print-ready artwork (AI, PDF, CDR)
Approving pre-production samples promptly
Ordering during non-peak season (avoid Q3–Q4 rush)
What causes delays:
Artwork revisions (each round adds 3–5 days)
New coating qualification (adds 5–7 days)
Customs clearance for export (outside our control but we assist)
Force majeure (we'll communicate proactively)
Bonus: 3 Questions Buyers Forget to Ask (But Should)
Q: Can you match my existing can dimensions if I'm switching suppliers?
Yes — send us a sample can and we'll measure and replicate diameter, height, opening, and coating. We can also improve on weak points (e.g., upgrade lining if the old supplier had corrosion issues).
Q: Do you provide valves, actuators, and caps too?
Yes. We supply a complete aerosol package — cans, cones, domes, valves, actuators, and caps. One PO, one shipment, one quality standard.
Q: What if my first order is small but I plan to scale?
We support ramp-up programs. Start with a smaller MOQ on stock sizes, prove the market, then graduate to custom-printed runs. Many of our long-term clients started at 5,000 pcs and now order 500,000+ per month.
The Bottom Line
Sourcing aerosol cans isn't just about price per unit. It's about getting the material, lining, pressure rating, and timeline right for your specific product. The five topics above cover 90% of what goes wrong in aerosol packaging — and we'd rather answer them upfront than fix problems later.
