A Complete Guide to Buying Empty 2g Disposable Vapes in Bulk

A Complete Guide to Buying Empty 2g Disposable Vapes in Bulk

What "2g" (2-gram) empty disposables actually are

An empty 2g disposable is a fully assembled, rechargeable all-in-one device (battery + tank + mouthpiece + heater) shipped without oil. Brands fill, cap, and—after required testing and labeling—sell into their licensed markets. Key components you’ll evaluate:

• Tank & materials: PCTG/food-grade polymers or glass; stainless steel center tube; silicone gaskets. For EU-bound nicotine products, materials and restrictable substances should comply with RoHS.
• Coil: Porous ceramic with tightly controlled resistance for thicker distillates/live resin.
• Battery: Typically 280–500 mAh Li-ion with USB-C recharge; cells should be validated to recognized safety standards and pass UN38.3 transport tests.

For international shipments that include batteries, your forwarder will also apply IATA lithium battery rules.

Why 2g formats are trending in B2B

• Unit economics: Fewer SKUs per flavor set and lower per-gram packaging/handling costs for licensed fillers.
• Consumer value: Longer service life per device and fewer re-purchases.
• Brand canvas: Larger chassis supports on-device screens, battery indicators, or anti-counterfeit elements without crowding.

On ExtractsVape you’ll see emphasis on custom tooling (shell colors, windows, mouthpiece geometry) and OEM white-label support aimed at helping brands differentiate at the enclosure level.

Compliance & safety: what matters before you buy

Even though you’re sourcing hardware only, your eventual finished goods must satisfy market-specific rules. Build these checks into your purchase order (PO):

1. Battery & transport — Request UN38.3 test summaries and align with IATA lithium battery guidance.
2. Restricted substances & electronics — For EU shipments, verify RoHS conformity and request a Declaration of Conformity.
3. Battery safety — Prefer vendors who certify cells/pack assemblies against IEC 62133-2 to reduce risk of thermal events.
4. Market-specific rules — EU nicotine vapes: TPD constraints; U.S. cannabis markets: state regs govern heavy metals, residual solvents, and hardware leachability once filled; China GB standards provide useful manufacturing references.
5. Ingredient safety frameworks (for your oils) — If SKUs use non-cannabinoid ingredients, follow ASTM D37 guidance and toxicological risk-assessment best practices.

Buyer’s checklist for empty disposable vapes bulk (2g)

Use this practical checklist when you evaluate factories and quotes:

6. Device engineering

• Coil & wick match to your oil viscosity (live resin vs. distillate; target resistance & power curve).
• Airflow design (postless or center-post; anti-leak labyrinth).
• Sealing & capping: snap-fit tolerances; torque spec if threaded; tamper-evident bands.
• Battery & PCB: short-circuit, over-charge, over-discharge protections; USB-C port robustness.
• Window & branding: oil-level window accuracy; space for QR/anti-counterfeit label and regulatory marks.

7. Documentation to collect

• 3 test summary (cell/pack).
• RoHS Declaration of Conformity (or third-party screening).
• Battery safety test reference (IEC 62133-2).
• Material datasheets (PCTG, silicone, stainless grades).
• Filling & capping SOP with temperature, dwell times, and cap-press requirements.
• Packaging spec (individual blisters, trays) optimized for air freight and final retail presentation.

8. Pilot & QA

• Incoming QC (IQC): Visual + dimensional checks (o-rings, fitment).
• Pilot fill: At least three oil types (light, medium, heavy) across a temperature range.
• Stress tests: Vacuum/altitude simulation (air cargo), thermal cycling (−20 °C to 60 °C), and multi-angle drop tests.
• Post-fill hold: 48–72 h upright + inverted leak check before large-scale run.
• Shelf-life simulation: Elevated temp storage and weekly test-fire.

Cost levers when buying 2 gram disposable vape bulk

• MOQ & colorways: More color splits = higher piece costs. Combine colorways for best pricing.
• Custom tooling: New molds amortize over volume; decide early if a stock shell suffices.
• Battery spec: Higher-capacity or smart displays raise BOM and shipping class.
• Packaging: Retail-ready packaging vs. bulk trays (bulk saves cost/weight).
• Freight mode: Ocean reduces cost but adds lead time; air requires strict IATA compliance for lithium batteries.

How ExtractsVape positions itself (and how to vet any supplier)

What you can expect on ExtractsVape:

• OEM/ODM focus for wholesale vape hardware (empties) with custom colors, branding, and accessory packaging.
• Model variety across 1g and 2g, plus guidance pages on choosing disposable pens—useful for spec comparisons within one vendor.

Due-diligence steps you should always take:

9. Ask for recent production references for 2g devices specifically (photos/videos of automated capping, leak-testing rigs).
10. Request batch-level traceability (date codes on PCBs/batteries, mold cavities).
11. Run a structured pilot: 200–500 pcs across two coils (if available), three oil viscosities, and at least two environmental conditions.
12. Third-party inspection before shipment; require AQL and a battery SoC setting compliant with IATA.

FAQs for first-time 2g buyers

Q: Are 2g devices legal everywhere?

A: No. Legality depends on the oil and jurisdiction. Hardware buyers should consult local regulators; for EU nicotine products, TPD rules apply; for U.S. cannabis, state-level testing and labeling govern.

Q: Do I need RoHS if I sell only in North America cannabis markets?

A: RoHS is EU law for electrical/electronic equipment, but many North American brands follow it voluntarily to reduce risk and keep options open for future markets.

Q: What battery paperwork does my forwarder need?

A: Keep the UN38.3 test summary on hand and follow IATA marking/SoC rules for any air shipment that includes lithium cells.

Q: Do I have to send hardware to a cannabis lab before sale?

A: Once filled, your finished vape must pass your state’s compliance tests (e.g., heavy metals, residual solvents). Plan your hardware choice to minimize leach risk.

A sample PO language you can adapt

“Supplier shall provide: (1) UN38.3 test summary for the integrated Li-ion pack; (2) RoHS Declaration for the assembled device; (3) confirmation of cell compliance to IEC 62133-2; (4) complete material list for all wetted parts; (5) filling/capping SOP including torque/press specs; and (6) packaging spec suitable for air freight under IATA lithium battery guidelines.”

Key takeaways (save this)

• Choose hardware with documentation that maps cleanly to UN38.3, IEC 62133-2, and RoHS—your future self (and freight partner) will thank you.
• Align early with your market’s testing regime (heavy metals, residuals) to avoid surprises post-fill.
• Pilot aggressively before a large 2 gram disposable vape bulk order; test across oil viscosities, temps, and shipping simulations.
• Use vendors (like ExtractsVape) that can back empty disposable vapes bulk claims with traceability, SOPs, and customization for your wholesale vape roadmap.
