We operate on a request-first basis. A $10 deposit is required immediately after submission to initiate manual processing. Stock is verified directly with synthesis facilities before the final invoice is issued.
No payment yet.
Browse the catalog and add compounds to your request. Provide your contact details and submit. This is a sourcing request — not a purchase. No payment is collected at submission.
Paid immediately after submission.
A $10 processing deposit is required immediately after your request is submitted. This initiates manual processing and reserves sourcing time. The $10 is not an extra fee — it is fully credited toward your final invoice.
Direct facility check.
After the deposit is received, we check real-time availability directly with the relevant synthesis facility. This is a manual process — we do not draw from pooled inventory. Verification and the supplier's response typically take about 2 business days (China time, GMT+8).
Pay balance, order ships.
Once stock is confirmed, you receive a final invoice. If any items are unavailable, the invoice is adjusted accordingly. After final payment, processing, assembly, and handover to the carrier take 2–3 business days — delivery time is counted from that handover.
Key commercial terms that apply to all requests on this platform.
The final invoice may be adjusted if some requested items are unavailable at the time of verification. You will be notified before payment is collected. Stock is verified manually after each request and deposit.
Shipping typically ranges from $55 to $75 per parcel. Standard shipping is $55–$60 with an estimated transit time of 15–20 days. Express shipping is $75 where available, with an estimated transit time of 7–12 days. The final shipping cost is confirmed based on the supplier, destination, and parcel count before final payment. Transit is counted from handover to the carrier, and customs handling times are outside our control.
