Peptide Serum Wholesale and OEM Questions

Clear answers about samples, MOQ, product specifications, documents, packaging, shipping, payment and destination-market responsibility.

Before you order

Questions procurement teams should resolve in writing.

If your question depends on a product or batch, send the catalog code and destination market so we can reply accurately.

What information is required for a wholesale quotation?

Send the product name or catalog code, product form, quantity, pack size, destination country, required documents and target delivery date.

Can I request a sample before a bulk order?

Samples can be discussed for selected raw materials, stock solutions and finished formulas. Sample availability, fee, pack and freight are confirmed by product and destination.

What is the MOQ?

MOQ depends on whether the item is a raw material, stock solution, neutral finished serum or customized package. The written quotation states the applicable MOQ after the pack and customization scope are confirmed.

Do you provide COA and SDS files?

Document availability is confirmed for the exact product and batch. A COA, SDS, commercial specification or additional test report may apply depending on the material and project.

How do you confirm stock-solution composition?

The quotation should identify the active or peptide complex, concentration basis, carrier or solvent system, preservative information where applicable, appearance, storage and available pack.

Can you develop a private-label serum?

Yes. The project begins with destination market, formula direction, packaging, quantity, claims direction and required launch date. Samples and artwork are approved before production.

Can I use my own bottle or packaging supplier?

This can be reviewed. Bottle compatibility, closure, decoration, delivery to the filling site, loss allowance and responsibility for defects must be agreed before production.

How long does OEM development take?

Timing depends on formula complexity, sample rounds, packaging availability, artwork approval, testing scope and order quantity. We issue a project schedule after these variables are confirmed.

What quality checks apply to finished serum?

The release specification may include appearance, pH, fill volume, packaging checks and microbiology. Additional stability, compatibility, heavy-metal or challenge testing must be agreed by project.

How should peptide materials be stored?

Storage depends on the material and formulation. Follow the product label, supplier specification and batch documents; do not assume that all powders, solutions and finished serums share one condition.

Do you ship internationally?

Shipping may be arranged by express, air or sea according to product, volume, destination and document needs. The available route is confirmed before the proforma invoice.

Which Incoterms are available?

The quotation states the applicable trade term. Availability depends on destination, product type, order size and the selected logistics route.

Which payment methods are accepted?

Payment instructions are issued only on the official proforma invoice. T/T and other approved B2B arrangements may be available; always verify bank details through the official email before payment.

Can you support distributor projects?

Qualified distributors can discuss SKU selection, sample validation, document scope, tier quotation, forecast and repeat-order planning.

Can you guarantee a cosmetic claim or regulatory approval?

No supplier should guarantee market approval from a product name alone. The buyer is responsible for destination-market ingredient, claims, labeling and notification requirements.

How are shipping damage or quality concerns handled?

Send photos, lot or batch reference, packaging images and shipping documents promptly. The case is reviewed against the approved specification, trade term and carrier responsibility.

Still need an answer?

Send the product, quantity and technical question.

We will respond by email or WhatsApp and identify which information must be confirmed in the quotation.
