Eau de Parfum is a finished fragrance you can wear as supplied. Fragrance oil is a perfume concentrate for formulation and must not be applied undiluted. At Class Parfum these are two separate product ranges, with different sizes and fulfillment routes.
If you want perfume for everyday wear or a compatible refillable atomizer, start with 20% Eau de Parfum refills. If you need an ingredient for a perfume-making project, explore pure fragrance oils.

Choose Eau de Parfum if you want a ready-to-wear refill
The Eau de Parfum range is for buyers who want finished fragrance without a formulation step. A 20% concentration describes the proportion of aromatic fragrance material in the finished formula; it does not mean the bottle contains undiluted perfume concentrate.
Start with a manageable size and a scent direction you enjoy. The 100ml format can suit personal use or testing demand. Consider 500ml or 1000ml only when your repeat refill, sampling or reseller needs justify the additional volume.
A sprayer is not included. Read how to use an Eau de Parfum refill for compatible containers and transfer instructions, or compare refill sizes before ordering.
Choose fragrance oil if you are developing a perfume formula
The fragrance oil range supplies perfume concentrate. Choose it when you need an ingredient for a formulation project and can evaluate the finished blend, rather than when you simply want to refill a personal atomizer with ready-to-wear perfume.
Do not apply the concentrate undiluted. Appropriate formulation and usage levels depend on the specific fragrance and intended application. Ask for the relevant product documentation and confirm suitability for your project before scaling. A concentration percentage alone does not establish that a finished product is suitable for every use.
Use the catalog name or C code when asking about fragrance oil. For a wholesale or custom project, also provide the quantity, destination, intended use and any packaging or document requirements through the wholesale inquiry page.
Keep product type and scent direction separate
A familiar scent direction can appear in different product formats. Choosing the same inspiration does not make a concentrate interchangeable with finished Eau de Parfum. Read the product type, preparation requirements and fulfillment details before adding it to your cart.
Class Parfum products are independent fragrance interpretations. Designer references describe a scent direction; they do not identify an original designer perfume or an official designer refill.
Common buying questions
Can I use fragrance oil to top up my perfume atomizer?
Do not pour undiluted concentrate into an atomizer and use it as finished perfume. Choose ready-to-wear Eau de Parfum if you want a refill without a formulation step.
Can I order both ranges together?
Both ranges can be added to the same cart, but Eau de Parfum ships from Kansas and fragrance oil ships separately from China. Each fulfillment route has its own shipping charge; review the checkout details before paying.
Does 20% concentration guarantee all-day wear?
No. Formula, scent materials, application, skin and environment affect performance. See what 20% fragrance concentration means for the distinction between concentration, longevity and projection.
Which range should a new reseller start with?
Choose according to what you intend to sell. A finished-fragrance reseller can begin with a smaller Eau de Parfum order and validate demand. A business making its own finished formula needs concentrate, suitable formulation knowledge and product-specific documentation. Use the wholesale page if you need help selecting a supply path.
