Structured Technical Parameters

Ordering Options

This product is sold by full-carton quantity. Select your preferred shipping method and available order quantity option before adding the product to cart. Online pricing is calculated based on the selected carton quantity and shipping method.

1 carton = 1,800 sets. 1 set = 1 bottle + 1 matched 18/410 CRC cap. Bottles are shipped by full bottle carton, while caps are matched by set quantity and may be packed separately in smaller cartons.

Air Freight – 10–15 business days: Recommended for urgent orders, trial orders, sample kits, small-carton replenishment, and emergency stock needs. Air freight is faster but has a higher landed cost.

Sea Freight – 40–60 business days: Recommended when landed cost is the priority. Sea freight cost advantage starts from 17 cartons. For 1–16 cartons, air freight is usually recommended because small sea shipments may not provide a meaningful logistics cost advantage.

For 100,000+ sets, custom logo printing, custom bottle color, mixed packaging requirements, or special delivery arrangements, please request a custom quote before placing an online order.

Stock Availability & Lead Time

Online order quantities are based on full-carton supply, but current stock availability may not always be sufficient for the selected order quantity. If available stock is insufficient, an additional 7–10 business days may be required for stock preparation before shipment.

For urgent orders, tight delivery schedules, or large carton quantities, we recommend submitting a custom quote request before placing an online order. Our team can confirm available stock, preparation time, shipping method, destination address, and final order feasibility before you proceed.

Shipping & Delivery

Bottles are sold and shipped by full bottle carton. Caps are matched by set quantity and may be packed separately in smaller cartons.

Air freight: Usually 10–15 business days after order confirmation. Air freight is mainly used for sample kits, small case orders, urgent trial orders, and emergency replenishment orders.

Sea freight: Usually 40–60 business days after order confirmation. Sea freight is recommended for bulk orders when landed cost is the priority and normally provides a stronger cost advantage for B2B packaging buyers.

Prices shown online include the selected shipping option, but final freight cost and delivery time may vary by destination country, delivery address, customs clearance, destination surcharge, carton measurement tolerance, and carrier schedule. Final order acceptance is subject to freight review after checkout.

Compatibility Note

PET compatibility varies significantly by fragrance-oil formula. Compatibility testing is strictly required before placing bulk orders, especially for high-citrus, high-solvent, or high-concentration formulas. We highly recommend ordering our standard sample kit for a 30-day compatibility and leakage test. Unalilia assumes no liability for bottle collapsing, distortion, leakage, whitening, or other packaging failures caused by untested fragrance oil chemical reactions.

FAQ

Q: How do I place an order?

A: Select the available shipping method and order quantity option, then add it to cart. The checkout amount is calculated based on the selected carton-based order option.

Q: How many sets are included in one carton?

A: 1 carton includes 1,800 bottle sets. 1 set = 1 bottle + 1 matched 18/410 CRC cap.

Q: Can I choose air freight for more than 16 cartons?

A: Yes. Air freight can be selected for urgent delivery when speed is more important than landed cost. For larger air freight orders, final acceptance is subject to freight review.

Q: Why does sea freight become cheaper from 17 cartons?

A: Sea freight has fixed logistics handling costs. For very small quantities, the landed-cost advantage is limited. From 17 cartons, sea freight becomes more suitable for bulk B2B replenishment orders.

Q: Are the bottles suitable for diffuser oils?

A: They are designed for diffuser refill and replacement applications, but oil compatibility depends on the formula. Sample testing is required before bulk orders.

Q: Which shipping method should I choose?

A: Choose air freight for urgent delivery, samples, small-carton orders, or emergency replenishment. Choose sea freight for bulk orders when landed cost is the priority.

Q: Do you support custom logo printing and custom bottle coloring?

A: Yes. Unalilia offers factory-direct custom services including silk-screen printing, hot stamping, label application, shrink sleeve options, and custom bottle coloring. For custom logo printing or custom bottle color, the standard MOQ is 10,000 sets. For stock clear bottles, smaller case-pack orders may be available based on full bottle-carton quantity.
