FAQ
Working With UJW
For importers, distributors, and OEM buyers.
Why choose UJW as a bio media supplier? +
UJW works as a factory-side supplier for biological filter media rather than only a trading source. Buyers work with us for manufacturing experience, OEM/ODM support, export coordination, and repeat supply across ceramic and plastic bio media categories.
Which buyers do you mainly work with? +
Our main customers are importers, distributors, private-label brands, and larger project buyers in aquarium, koi pond, ornamental-water, and aquaculture-related markets. Most buyers already understand the product category and are looking for a reliable factory partner.
Do you provide OEM or private label programs? +
Yes. We support OEM and ODM programs covering product selection, media format, packaging, and private labeling, with stable factory execution for market-ready product lines.
Can you support mixed product lines and custom requirements? +
Yes. We can discuss mixed assortments, product-line planning, custom shapes or sizes, and packaging direction based on your target market and order structure.
How do you handle production capacity and lead time? +
Our monthly production capacity is approximately 360 tons of filter media. Standard lead time is typically 15 to 30 days after deposit receipt and final order confirmation, depending on quantity, media type, and customization scope.
What is your MOQ? +
For standard catalog products, the MOQ is typically 1 ton, and mixed assortments can be discussed based on the order program. Final MOQ depends on product type, packing method, and customization level.
Do you provide free samples? +
We can provide samples for evaluation. Sample kits are usually charged at a small fee to manage preparation and demand, but that cost can be deducted from a first bulk order. Courier cost is normally covered by the customer.
What are your payment terms? +
Our standard terms are 30% T/T as a deposit before production and 70% balance before shipment. For long-term partners and stable repeat programs, more flexible arrangements can be discussed.
Which shipping methods do you use? +
We regularly arrange sea shipment for bulk orders, including both FCL and LCL, because that is usually the most economical route. For smaller or urgent orders, air freight or express services such as DHL or FedEx can also be arranged based on destination and timing.
