How to choose empty disposable carts for cannabis oil brand?

Cannabis oil companies strive to produce flavorful, highly effective, top-quality, and safe essential oils. However, when these oils are ultimately used in poorly performing or substandard disposable carts, it can lead to product quality issues and deter consumers from making repeat purchases, thus significantly impacting the company’s brand image and sales performance. Therefore, as a cannabis oil company, it’s crucial not only to meticulously craft high-quality cannabis oil but also to devote significant effort to finding high-quality dispo cart hardware suppliers. By pairing good oil with excellent empty carts equipment, your products will receive rave reviews and fly off the shelves, allowing your brand to stand out in the fiercely competitive market and reap abundant profits. Below, we will share several key considerations for extraction companies when purchasing empty cart hardwares, including:

  1. Determining Vape Hardware Specifications: Style, Capacity, Functionality, Material Requirements

  • Step 1: Selecting the Battery System Based on Market Positioning and Demand: Disposable Vape Pen, 510 Thread, or Pod System vape.
  • Step 2: Choosing Empty Cart Capacity According to Oil Product Positioning: 0.5/1.0/2.0/3.0/4.0/5.0/6.0ml. It is recommended not to exceed 5ml as it is the limit of hardware quality. Excessive capacity can lead to issues such as clogging, incomplete vaporization, and unpleasant odors.
  • Step 3: Selecting Suitable Ceramic Heating Coil Empty Carts Based on Oil Characteristics. For example, in 2024, full ceramic cartridge technology (without a metal center post) will gradually become popular. This technology allows for full ceramic vaporization without any metal contact, ensuring perfect flavor and eliminating concerns about heavy metals.

  • Step 4: Choosing Variable Voltage Battery Based on Oil Characteristics. For example, Lives carts require three-mode adjustment between 2.2V and 3.0V, while delta 8 pens require three-mode adjustment between 3.0V and 3.7V.
  • Step 5: Selecting the appropriate Oil intake Hole Size Based on Oil Viscosity. For example, for carts with a center post, the intake hole for high-viscosity oil is generally between 1.8-2.0mm. Choosing a bottom full ceramic heating chamber eliminates such concerns, as the bottom ceramic heating functions like a funnel-shaped flat-bottomed pan, effectively absorbing and vaporizing the oil in a timely manner.
  • Step 6: Paying Attention to Hardware Trends. For example, the function of displaying battery adjustable voltage was previously popular. But starting in 2024, it is important to consider whether the battery requires an electronic display screen to show battery level, puff count, brand logo, etc.


  1. Collecting Samples and Finding Suppliers


Gather samples of all empties cartridge available in the market that meet your requirements as much as possible. There are three channels to consider: local wholesalers, Chinese traders, and Chinese factories.

Local Wholesalers: You can quickly obtain samples of cartridges empty and pens by the bulk from local wholesalers, but local suppliers may not offer custom pens in bulk options and often have higher costs compared to purchasing directly from China. If your purchase quantity is below 5000pcs/month, local procurement is recommended.

Chinese Factories: For purchase quantities exceeding 5000pcs/month, sourcing directly from Chinese factories aligns better with long-term interests. This allows access to the latest dispo carts products directly from Chinese factories, offering personalized pens bulk options and reducing procurement costs for vape cartridges.

Chinese Traders: If your purchase quantity is not large but you require a diverse range of customized products, Chinese traders are a good choice for one-stop procurement support.


How to Find Empty Vape Cartridges Manufacturers from China?

Before September 2022, China has approximately 4000 electronic cigarette manufacturing enterprises of various sizes. After September 2022, the Chinese government issued Electronic Cigarette Production Licenses to qualified enterprises, with over 400 companies obtaining this license and ordering the closure of all unlicensed electronic cigarette factories. Please make sure that your Chinese manufacturer has the following legal production licenses.

Alibaba and Made in China have already blocked suc products. Currently, there are only three ways to find Chinese factories:

Trade Shows: Attend exhibitions such as CHAMPS Trade Shows, MJBizCon, and Tobacco Product Expo.

Google Sources: Search for Chinese electronic cigarette factory websites.

Social Media: Utilize platforms like LinkedIn, Facebook, and Instagram.

  1. Product Testing and Evaluation

Even without a testing center, testing can still be conducted using the following methods:

  • Step 1: Check the appearance of electric pens for any obvious flaws and assess the craftsmanship.
  • Step 2: Drop several disposable pens from a height of approximately 1.2 meters to test for product damage upon impact.
  • Step 3: Assess whether empty cartridges are easy to fill with oil and convenient capping.
  • Step 4: After oil injection into pens carts, leave them for 48 hours and observe for any leakage.
  • Step 5: Conduct usage testing: Evaluate carts flavors for taste and aroma, assess vaporization efficiency, and check for any burnt or off flavors. Record the number of puffs achievable on a full charge; for 0.5ml and 1ml carts, they should ideally be finished all without recharging.

Check for oil leakage into the mouth, clogging issues, and the ability to vaporize the oil completely. Assess whether preheating is effective in facilitating oil flow at low temperatures, and verify the functionality of temperature settings (high, medium, low) without producing burnt flavors.

Step 6: Evaluate ease of packaging, storage, and transportation, ensuring there are no leakage incidents during these processes.

Select at least three qualified bulk carts suppliers for comparison and create a table for scoring.

  1. Tips for chooseing the supplier of vape cartridges

1)Highly cooperative suppliers

One essential factor to consider when selecting a manufacturer is their production capacity. For larger cannabis oil companies, partnering with a manufacturer capable of producing large quantities of empties cartridges in a timely manner is crucial. Conversely, for smaller enterprises or startups, suppliers offering smaller-scale cartridge supplies may be more suitable. Ensuring that your orders are prioritized in their production queue and delivered promptly is essential once the collaboration commences.

2)Supplier with Strong Customization Capabilities

Customization is also a critical consideration when choosing a manufacturer for empty vape cartridges and bulk logo pens. You need to find a supplier capable of customizing cartridges to meet your specific requirements, such as pen custom logo, white label, private label, colors, capacities, voltage settings, cartridge shapes, and more. Some manufacturers offer a wide range of customization options, while others may have more limited choices. Therefore, selecting a manufacturer that can meet your specific needs is essential.

3)Competitively Priced Suppliers

In selecting manufacturers or wholesalers of empties cartridge, first identify several styles you prefer and conduct reliability tests. Once you’ve ensured that the functionality and quality meet your standards, choose the supplier with the most competitive pricing. Building an excellent supply chain involves selecting 2-3 manufacturers or wholesalers whose products meet your needs, offer quality assurance, and competitive pricing, and effectively comparing prices. If purchasing locally, transportation costs need not be considered. However, if sourcing directly from China, transportation costs from China to the destination should be factored in. Regardless, do not sacrifice quality for price. While low prices may seem attractive, compromising on cartridge quality may result in greater losses in the long run.

4)Reputable or Quality Product Suppliers

For larger-scale manufacturers, reputation within the industry is crucial. Look for reviews and recommendations from local oil brands to see if they have had positive experiences with the manufacturer. For smaller-scale suppliers with unique products, inquire about their best-selling empty cartridge products and assess whether their market positioning, sales performance, and market presence align with your expectations.

5)Chinese E-cigarette Factories

If purchasing directly from Chinese factories, ensure that the supplier provides an “Electronic Cigarette Production Permit” to demonstrate compliance and legality. Without this permit, the manufacturer may be operating illegally, and in case of product quality issues, there may be no means of recourse. Each production and export of compliant enterprises with an “Electronic Cigarette Production Permit” is documented. If product issues arise, timely product replacement and compensation can be obtained.

Summary: Considering the factors outlined in this article such as capacity, features, materials, custom branding, quality, price, and supplier evaluation, make informed decisions. Choose a reputable manufacturer capable of meeting your specific requirements to provide your customers with high-quality dispo cart they love and build your business empire.
