If you're working in the pharmaceutical or medical device export business, you've probably seen inquiries like this:

Before discussing pricing or technical details, the buyer simply asks:

"Can you provide free samples?"

Some suppliers see this as a positive signal. They assume the buyer is ready to evaluate the product and hope that sending samples quickly will increase the chance of winning the order.

Others become cautious immediately, worrying that the buyer is only looking for free samples with no real purchasing intention.

In reality, both conclusions may be premature.

A sample request shows that the buyer is interested enough to evaluate the product, but it doesn't tell you why they need the sample, what they intend to do with it, or whether a commercial order is likely to follow.

Instead of rushing to ship samples, it's usually more valuable to clarify the buyer's requirements first.

Understand the Purpose of the Sample

A request for 5 grams of an API can mean very different things.

The sample could be intended for:

Laboratory testing

Formulation development

Supplier qualification

Registration preparation

Evaluation on behalf of an end customer

Each scenario represents a different level of purchasing potential.

A simple follow-up question can reveal much more about the project: "May I know the intended use of the sample? Is it for laboratory testing, formulation development, or supplier qualification?"

For medical devices, you could ask: "Is the sample for product evaluation, local registration, or distributor testing?"

You don't need to ask dozens of questions. Understanding the intended use is often enough to distinguish a serious project from a vague inquiry.

Confirm the Specifications Before Sending Samples

For APIs, peptides, excipients, and many medical devices, one product name may correspond to different grades, purity levels, salt forms, specifications, or configurations.

If a supplier sends a standard sample without confirming the buyer's exact requirements, the evaluation may fail simply because the sample doesn't match the intended specification.

Before arranging shipment, confirm:

Product specification

Grade or standard

Required sample quantity

For example: "Could you confirm the required grade or specification?"

If the buyer already has a product specification, it's even better to request it in advance so you can verify compatibility before shipping.

The Requested Quantity Can Tell You a Lot

The amount of sample requested often reflects the maturity of the project.

A few grams may be sufficient for initial laboratory testing.

Formulation development, pilot production, or equipment evaluation usually requires a larger quantity.

If a buyer immediately requests a relatively large amount of free samples but cannot clearly explain the intended application or future purchasing plan, it's reasonable to ask for additional information.

For example: "What sample quantity do you need for testing?"

If the requested quantity exceeds your company's normal sample policy, you can explain your policy clearly—for example, offering small evaluation samples free of charge while treating larger quantities as sample orders that may be credited toward future commercial purchases.

This approach is usually more productive than simply rejecting the request.

"Free Sample" Doesn't Always Mean Free Shipping

Many buyers asking for free samples are referring only to the product itself.

They may still expect to cover international courier costs.

For overseas shipments, logistics expenses can sometimes exceed the value of the sample itself.

Once the sample details have been confirmed, clarify the shipping arrangement early.

For example: "Samples can be provided free of charge, while courier costs will be collected." Or: "For the requested quantity, we can arrange a sample order first. The sample cost may be credited toward a future commercial order."

Whether you charge for samples depends on your product value, customer profile, and company policy. The key is to establish expectations before shipment.

Ask About the Buyer's Purchasing Plan

This step is often overlooked.

Many suppliers ship the sample and then repeatedly follow up with messages like: "Any feedback?" or "Have you completed the testing?"

Instead, ask one additional question before shipping: "If the sample meets your requirements, what would be your estimated order quantity?"

The buyer doesn't need to provide an exact number.

Even a rough indication—whether the project is for laboratory research, a trial order, or commercial production—helps you understand the opportunity and plan your follow-up strategy.

Which Sample Requests Deserve Higher Priority?

Not every sample request should automatically become a high-priority sales opportunity.

Higher-quality prospects usually provide additional information such as:

Clear specifications

Defined application or testing purpose

Reasonable sample quantity

Company background

Project information

Future purchasing expectations

On the other hand, if a buyer repeatedly says only:

"Free sample."

"Send immediately."

"Please pay the shipping."

while refusing to provide specifications, company information, or project details, it may be appropriate to lower the priority of the inquiry.

The willingness to share information is often an important indicator of project quality.

Follow Up According to the Testing Timeline

Once the sample has been shipped, don't simply monitor the tracking number.

Ask the buyer how long the evaluation is expected to take.

For example: "May I know approximately how long the evaluation will take?"

If the buyer expects a two-week testing period, follow up around that timeframe instead of asking for feedback immediately after delivery.

Your follow-up can also be more specific:

Has the sample arrived safely?

Does the specification meet your expectations?

Do you require additional documents such as a COA or product specification?

If the evaluation is successful, what would be the next step in your purchasing process?

Purposeful follow-up conversations are far more effective than repeatedly sending: "Any updates?"

Final Thoughts

Receiving a free sample request in the first inquiry is generally a positive sign—but it shouldn't trigger an immediate shipment.

Take a little time to confirm the specification, intended use, sample quantity, and potential purchasing plan before deciding how to provide the sample and how to handle the associated costs.

For pharmaceutical and medical device suppliers, sending samples is rarely the difficult part.

The real challenge is determining whether the sample has the potential to move beyond evaluation and into qualification, approval, and ultimately, a commercial order.

Asking the right questions before shipping can help reduce unnecessary sample costs while allowing your sales team to identify higher-quality opportunities much earlier.
