How it works

From first inquiry to repeat orders

Most buyers go from first message to a confirmed quotation within 24 hours.

1

Send us your product list

Products, strengths, quantities and destination country — or simply a screenshot of the list you buy today.

2

Get a quotation and review the batch COA

We confirm availability, MOQ, pricing and lead time, and share the LC-MS report for the batch you will receive. You pay only after you have reviewed it.

3

Start with a test order, then scale

Begin with a test order to check product and packaging, then move to recurring wholesale, bulk or private-label orders at volume pricing.

Why buyers choose us

Why distributors order direct from Fusen

When you resell, consistent batches and clear documentation matter as much as price.

Review the batch COA before you pay

Every quotation comes with the LC-MS report for the batch you will receive — purity, mass-spectrum identity and the raw chromatograms. Nothing is charged until you have reviewed it.

Factory direct, no middleman

You deal with our own sales and production team, so pricing, lead times and batch details come from the people who make the product.

OEM & private label

Your brand on the vial, label and box. Send finished artwork or work it out with our team; private-label MOQ is confirmed per project.

Formats for every channel

Lyophilised vials, single- and dual-chamber cartridges, disposable and reusable pens, and bulk supply for your own filling.

One account manager

The same person handles your quotation, production updates, shipping and repeat orders. No ticket queues.

Built for resellers

We help you sell — not just ship

Buying for resale is a risk. This is how we take most of it off your side.

Low-risk test orders

Start with a small mixed order to check demand in your market before you commit to volume.

Reports your customers trust

Share the batch LC-MS report for every lot you sell — it answers your buyers' first question for you.

Private label ready

Your brand on the vial, label and box, so the customers you win stay yours.

Know what sells

Our sales team tells you which lines distributors in your region reorder most.

Reliable restocking

Repeat orders run on confirmed lead times, so your best sellers never go out of stock.

One account manager

The same person handles your quotes, production updates and reorders.

Ordering terms

Start small, scale when it sells

No hidden thresholds. These are the numbers we work with every day — your exact quotation confirms them for your product mix and destination.

Standard MOQ

100 vials in total, mixed across any products in the catalogue. Test the market before you commit to volume.

Volume discount from

300 vials of one product. Discounts step up again at 500, 1,000 and 2,000 vials.

Private label from

500 vials per product, your artwork on vial, label and box. Artwork proof in 3 working days.

Lead time

Stocked lines ship in 3-5 working days. Private-label runs take 10-15 working days after artwork approval.

Cartridges, pens and bulk powder have their own minimums — ask us on WhatsApp and we confirm in the quotation.

Questions

Questions B2B buyers ask

Can I see the test report before I pay?

Yes. With every quotation we share the LC-MS report for the batch you will receive, including purity, mass-spectrum identity and the raw chromatograms. You review it first; only then do we ask for payment. Reports for recent batches are also in the Documents section of this page.

Are you a manufacturer?

Yes. Fusen Pharmaceutical operates as a manufacturing and B2B supply partner, so you deal directly with our sales and production team.

What is your MOQ?

MOQ depends on the product, strength, format and customisation. Tell us what you need and we confirm it in the quotation. Private-label MOQ can be higher than standard wholesale orders.

Can I place a test order?

Yes. For new partners we recommend starting with selected products and quantities, then moving to larger recurring orders once you are happy with product and packaging.

Do you support OEM and private label?

Yes — customised labels, boxes, inserts and branding for qualified orders. Send your artwork or discuss the packaging with our team.

How long does production take?

It depends on availability, quantity and customisation. We confirm the production time and shipping option in your quotation before you order.

Do you ship internationally?

Yes. Shipping is arranged according to the destination and the order. Buyers are responsible for the import and resale rules of their own market; ask us what customers in your country normally use.
