Built for supplements, not just any parcel.

Create bottles, labels, cartons, and gift boxes that feel distinct instead of settling for stock packaging.

Inventory where you need it
Start with China-direct fulfillment, hold proven products in US warehouses, or use both at the same time.

Delivery customers can track
China-direct orders reach US customers in 5 to 10 days. Every parcel includes tracking from dispatch to delivery.

Customs handled end to end
Supplement paperwork needs extra care. We prepare shipping documentation and manage the clearance workflow.

Shopify, TikTok Shop, Amazon, and eBay all read from the same live stock pool, reducing overselling and idle inventory.

FAQ
Questions we hear before the first call.
We already have a manufacturer. Can we still work with you?
Yes. Some clients keep their current production and use us for packaging, warehousing, and fulfillment. Others move production after reviewing the cost and lead-time comparison. Both approaches work.
Is there a minimum order quantity?
There is no MOQ for dropshipping orders. For custom formula and packaging, minimums depend on the product and usually begin at 500 to 1,000 units.
What does TikTok Shop integration actually mean?
Orders flow into our system directly and draw from the same inventory as your other channels. There are no CSV exports, separate stock allocations, or manual copying between dashboards.
Who owns the formula?
You do, and it is written into the agreement. Formula exclusivity means your blend will not appear under another brand.
How long does onboarding take?
A standard transition takes four to six weeks. New formula development or a second market can take longer. You receive a dated schedule before work begins.
Can we visit your warehouse?
Yes. Clients visit regularly. If travel is not practical, we can provide a live video walkthrough of the racking, QC bench, and packing line.
Do you help with FDA requirements?
We work to your labeling and documentation requirements and coordinate the compliance workflow with the facilities. We are not regulatory counsel, but our team has supported this process many times.
