Your Guide to Private Label E-Liquid Manufacturing

Entering the competitive e-liquid market as a new brand can be challenging. A lot of time and expense go into developing a high-quality e-liquid formulation, sourcing the right materials, nurturing beneficial supplier partnerships, and building a positive product reputation among a customer base that trusts and enjoys your brand. You also have the added pressure of making sure that you have the best manufacturing equipment for the job, the trained staff to give you the capacity you need to meet demand, packaging and warehousing capabilities, and the list goes on.

This is where private label e-liquid production is beneficial. Private labeling allows your company to choose from e-liquid formulations and products that a reputable e-liquid manufacturer has already developed and sell them under your own branding and packaging. The manufacturer will handle material procurement and production so that you can focus on sales and marketing your brand.

Read on to learn more about e-liquids, our private label manufacturing process, and the benefits of partnering with Daily Manufacturing for proven e-liquid formulas to sell under your brand.

What Is in E-Liquid Juice?

The liquid within e-cigarettes goes by multiple names, such as e-liquid, e-juice, and vape juice. There is no set formulation, but common ingredients include:

Vegetable glycerol/glycerin

Propylene glycol



Additional chemicals or concentrates to give the liquid a specific flavor

E-liquid formulations can also contain varying amounts of the above. For example, e-liquids can be nicotine-free or they can contain low to high amounts of the substance, depending on your preference.

Is E-Liquid the Same as Vape Juice?


Yes. The names e-liquid, e-juice, and vape juice all refer to the same thing: the liquid you use in e-cigarettes and vape pens. E-liquid is sometimes considered the more official of the three, but you can use them interchangeably.

Manufacturing E-Liquids

To produce quality private label vape juice and help you stay ahead in an increasingly competitive market, the typical e-liquid manufacturing process consists of the following steps.

  • Step 1: Obtaining Quality Materials From Trusted Partners

    Your product can only ever be as good as its ingredients, which is why Daily Manufacturing works with reputable suppliers to secure quality raw materials. We maintain partnerships with vendors we trust to supply superior ingredients in a timely fashion so that you can rely on us for fast turn times.

  • Step 2: Measuring the Ingredients for Optimal Product Safety and Consistency

    Next, we measure out all e-liquid ingredients in precise weights based on the desired e-liquid formulation. This ensures not just a consistent product for your customers, but also peace of mind that the end product will be safe for consumers. Daily Manufacturing offers a broad spectrum of proven formulation options to best meet your preferences.

  • Step 3: Blending the E-Liquid Formulation

    Once we’ve ensured that we have all the ingredients prepared and accurately proportioned, we’ll blend them together, mixing the necessary propylene glycol, vegetable glycerin, water, nicotine, and desired flavoring agents manually or using automated equipment. To deliver formulations of the highest quality, we utilize a Class 1,000 or ISO 6 clean room for blending processes, as well as for the next step: bottling.

  • Step 4: Bottling and Capping

    Using automated equipment, we fill sterile bottles with the completed e-liquids and seal them using tamper-evident closures to protect them from spillage as well as contaminants. At Daily Manufacturing, we have a bottling capacity of over 150,000 e-liquid bottles each day. A finished bottle typically contains a dropper or nozzle for dispensing purposes.

  • Step 5: Labeling and Batch Coding

    After we fill and cap the bottles, each one receives a label as well as a batch code number for optimal ingredient and product traceability even in mass-production manufacturing runs. The label will contain not only standard information such as the product and brand or company names and e-liquid ingredients, but also any compliance verifications or warnings the law or regulatory bodies require. As a private label manufacturer, labels will contain your branding information rather than our own.

  • Package Testing
    Step 6: Final Quality Control Testing

    As an ingestible substance, it’s essential to include quality control and related testing as part of the manufacturing process. We closely monitor our e-liquids during formulation and production to verify proper blend and contaminant-free manufacturing, but prior to distribution, we also run final tests such as chemical or nicotine analyses, visual inspections, and flavor tests.

  • Step 7: Assembly and Packaging for Shipment

    The final step of e-liquid manufacturing is packaging the e-liquid products approved for shipment. We’ll pack the individual bottles securely into boxes for safe warehouse storage and/or transport so that they’ll arrive safely. We incorporate automation into this process as well for added efficiency and precision.

What to Consider Before Picking an E-Liquid Manufacturer

As e-liquid manufacturers all provide different services and adhere to varied quality standards, selecting the one that can accommodate your e-liquid and private label requirements is vital. However, there are also some basic attributes that any manufacturer should possess if you're considering partnering with them:

ISO certification

Reliable quality control procedures

Rapid lead times

Proven success in producing quality e-liquids

Transparent processes and open communication

Is Certified Production Necessary to Improve E-Liquid Quality Standards?

By law, it isn’t necessary for companies to be certified to manufacture e-liquids. That said, partnering with a certified manufacturer ensures that you’re going to receive safe, consistent, high-quality e-liquids with accurate formulations. It also keeps your customers happy, as any slips in product quality or formulations might have them seeking out e-liquids from your competitors, of which there are many in today’s market. Also, the FDA began regulating e-cigarettes in 2016, so all vape juice manufacturers should be FDA-registered.

As part of our dedication to excellence, Daily Manufacturing complies with all necessary industry standards to surpass customer expectations. We maintain certifications and registrations that ensure high quality and safety in our products and formulations. We’re an FDA-registered manufacturer, adhere to CGMP regulations in our operations, and hold an ISO 9001:2015 certification. Our commitment to regulatory compliance is a testament to the accuracy of our formulas and labeling, the quality of our ingredients, and the safety of our products.
