Frequently Asked Questions

Answers to common questions about fragrance oils, bulk orders, samples, lead time, compliance, and OEM service.

Trial Orders & Samples

Sampling is supported, but it should connect to a real B2B product decision.

Do you provide fragrance oil samples?

Yes. We support fragrance oil samples and trial orders for real B2B projects. Before recommending samples, we usually need to understand your application, scent direction, target market, expected quantity, and testing purpose.

For many perfume fragrance oil projects, we recommend starting with a 1kg trial order per scent for practical formula and market testing. Small 10ml samples may be used for early evaluation or packed with a trial order when the project route is clear.

What is the best starting route for a new fragrance oil project?

It depends on your project type:

  • Perfume fragrance / inspired scent directions: usually 1kg per scent, or 4–5 scents × 1kg trial order.
  • Application testing: usually 3–5 paid fragrance directions for car spray, diffuser, candle, detergent, fabric care, or cleaning products.
  • Custom development: clear brief or physical reference sample, target cost, expected order quantity, and development deposit are required.

Do you provide a fixed open catalogue or full price list?

No. We do not provide a fixed open catalogue or full public price list. We usually recommend suitable fragrance oil options based on the buyer’s application, reference scent, target performance, quantity, and budget.

Do you offer free samples?

Free random samples are not our default process. Sampling arrangements depend on project details, sample scope, shipping cost, and order plan. Our goal is to keep sampling useful for both sides, not to send random scent options without a clear project direction.

MOQ & Orders

What is your minimum order quantity (MOQ)?

MOQ depends on fragrance type, application, stock status, packaging, and development route. Common reference points are:

Project type Typical starting point
Perfume fragrance oils / perfume concentrates Often 1kg per scent for trial order
Existing library / inspired scent directions 1kg per scent, or 4–5 scents × 1kg trial order
Air care, candle, cleaning, fabric care, and other application projects Confirmed by application, fragrance direction, and testing plan
Custom development Confirmed after brief, target cost, and expected order quantity
Final MOQ should be confirmed before quotation because different fragrance oils and applications may require different production arrangements.
Do you support small trial orders before bulk production?

Yes. For many B2B projects, a 1kg trial order per scent is a practical way to check formula fit, performance, production quality, and market direction before moving into larger orders.

How do you quote fragrance oils?

Price depends on fragrance direction, raw material structure, target performance, order quantity, document needs, and shipping method. We do not quote all fragrance oils as one flat price.

Do you offer volume-based pricing?

Yes. Bulk pricing can be discussed after confirming the fragrance oil, target quantity, delivery country, and packaging requirement.

Documents & Compliance

What technical documents can you provide?

For confirmed fragrance oils, we can discuss available documents such as SDS / MSDS, IFRA certificate or statement, COA, and allergen-related information. Document availability may vary by fragrance oil and application.

Are your fragrance oils IFRA compliant?

Our fragrance oils are developed with IFRA usage considerations. IFRA limits depend on the final product category and dosage, so the exact application should be confirmed before using the fragrance oil in production.

Can you provide CPNP, CPSR, or finished product compliance documents?

CPNP, CPSR, Responsible Person, finished product labeling, and local market registration are usually finished product responsibilities. We provide fragrance-level documents where available, but final product compliance should be confirmed by your own team or local professional advisor.

Do you disclose full formula percentages?

No. We can provide available technical documents for confirmed fragrance oils, but internal formulation details and full formula percentages are not disclosed.

Application Testing

Can your fragrance oils be used in perfume, diffuser, candle, detergent, fabric care, or cleaning products?

Yes. We supply fragrance oils for different applications, including perfume, air care, candle, fabric care, household cleaning, and other product systems. The fragrance oil should be selected according to the application and tested in the buyer’s own base or formula.

Who is responsible for stability, compatibility, and performance testing?

The buyer should test the fragrance oil in their own base, formula, solvent, wax, packaging, and production process. Stability, compatibility, clarity, color, dosage, and final performance can be affected by the full product system, not only by the fragrance oil itself.

Can perfume fragrance oils be mixed with alcohol?

Some fragrance oils are suitable for alcohol-based perfume applications, but the final clarity, stability, dosage, and performance should be tested in your own alcohol base and formula before production.

Are fragrance oils safe to apply directly on skin?

Fragrance oils are concentrated materials, not finished consumer products. They should not be treated as ready-to-use skin products. Safe use depends on the final product formula, IFRA category, dosage, and local requirements.

OEM & Custom Development

Do you offer OEM or custom fragrance development?

Yes. We support OEM and custom fragrance oil development based on product application, scent direction, target cost, expected order quantity, and testing requirements.

What do you need for custom development?

A physical reference sample is preferred. If no physical sample is available, please share a clear brief, application, scent direction, target cost, expected quantity, market positioning, and performance requirements. Custom development usually requires a development deposit.

Can you make inspired scent directions?

We can support inspired scent directions based on clear references and project requirements. We do not promise 100% identical copies. The goal is to balance overall scent character, performance, commercial value, and practical production quality.

Can you adjust a fragrance after testing?

Our engineers can discuss reasonable adjustments based on your testing feedback, such as strength, freshness, sweetness, diffusion, or overall balance. Custom adjustment is not an unlimited free sampling process.

Shipping & Payment

What is the typical lead time?

Lead time depends on fragrance oil, quantity, stock status, and document needs. Small trial orders or available fragrance oils may be prepared faster, while custom development or larger bulk orders require a confirmed production schedule.

What shipping methods are available?

Common shipping methods include express courier, air freight, and sea freight. The suitable method depends on destination country, order weight, product type, and import requirements.

How is shipping cost calculated?

Shipping cost is quoted based on destination, shipment weight, courier or freight method, and product details. Please share your delivery country and approximate order quantity so we can check a suitable option.

What payment methods do you accept?

We commonly accept bank transfer (T/T) and PayPal. Other methods can be discussed based on order details.
