FAQ
Working With UJW
Why choose UJW as a bio media supplier? +
UJW is a direct manufacturer of biological filter media, so buyers can skip trading layers and discuss specifications, packing, pricing, samples, and repeat orders with the production side. Our 26+ years of manufacturing experience support clearer communication, faster quotes, quality control, and stable long-term supply.
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 for private labels, including custom media sizes, shapes, mold tooling, logo presentation, retail packing, bulk cartons, labels, and export-ready outer cartons.
Can you support mixed product lines and custom requirements? +
Yes. UJW has 200+ models across ceramic and biological filter media categories. Buyers can combine standard products with OEM / ODM options for mixed assortments, custom shapes or sizes, private-label packing, and market-specific product lines.
How do you handle production capacity and lead time? +
UJW produces approximately 360+ tons of filter media per month. Standard lead time is typically 15 to 30 days after deposit and final order confirmation, depending on quantity, media type, packing format, 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 50% T/T before production and 50% 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.
