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 offer paid evaluation routes for B2B projects. Selected Perfume fragrance oils are available as 1KG paid trials. Candle and Air Care projects can start with 10ml or 30ml paid samples. For other applications or custom development, contact us with your application, scent direction and expected order quantity so we can confirm the suitable evaluation route.

Choose the route that matches your application:

  • Perfume → selected 1KG paid trial products
  • Candle → 10ml or 30ml paid samples
  • Air Care → 10ml or 30ml paid samples

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

It depends on the application. Selected Perfume fragrance and inspired scent directions use 1KG paid trial products. Candle and Air Care projects use 10ml or 30ml paid samples. For other applications or custom development, contact us for a project-specific evaluation route.

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.

MOQ & Orders

What is your minimum order quantity?

MOQ depends on fragrance type, application, stock status, packaging and project route. Selected Perfume fragrance oils are available as 1KG paid trials; Candle and Air Care projects can start with 10ml or 30ml paid samples. Other applications and custom development are confirmed project by project.

Do you support small trial orders before bulk production?

For selected Perfume fragrance oils, a 1KG paid trial is intended for formulation and market evaluation before repeat supply in 5KG, 10KG or 25KG quantities. Candle and Air Care projects use the 10ml/30ml paid-sample route for application evaluation.

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 We do not quote all fragrance oils as one flat price.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. The custom development route is confirmed after project review.

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?

Payment methods and payment timing are confirmed in the quotation, proforma invoice or order communication for each transaction.
