Frequently Asked Questions and Answers

What are your hours of business?

Our customer specialists are available to answer your questions Monday through Friday, from 8:30 am to 5:00 pm Eastern Standard Time. However, you can always browse our products, request samples and place orders on our website.

I don’t have an account with your company. How can I open one?

To open an account, please register your company information and include your Federal Tax Identification Number (if you are based in the United States). New accounts are validated at the time of first order.

Please note: in order to request samples or make a purchase, you must first provide a valid business resale certificate. (Resale certificates are not required for customers outside of the United States.) Please contact a customer service specialist to request a credit application. After the completion of a credit check and management approval, you can place orders using net 30 terms. You can also place orders by using a credit card.

Why does Qosina ask for my resale certificate?

By providing a valid resale certificate to Qosina, you can request complimentary samples and purchase our products without being charged sales tax. If you do not have a resale certificate, you may be charged sales tax in accordance with state laws.

Does Qosina sell to hospitals and doctors’ offices?

We do not sell directly to end users of medical consumables. This includes doctors’ offices, hospitals, and clinics. Qosina’s products are sold in bulk and are non-sterile. Our products require further assembly and sterilization to be suitable for direct patient use.

How can I tell whether an item is suitable for my needs?

You may request complimentary samples of many of our products for testing to ensure compatibility. We strongly recommend that you thoroughly test our components before purchasing. Our customer specialists can help you with all of your sampling needs. You can also request samples on our website after account registration.

Are your parts produced in a cleanroom?

The majority of the items we carry are molded in a cleanroom or clean environment. Qosina is ISO 13485, ISO 9001, ISO 22301 and ISO 14001 certified. For information about specific components, please contact a customer service specialist.

How are your parts inspected?

Qosina performs visual inspections in our ISO 13485, ISO 9001, ISO 22301 and ISO 14001 certified warehouse. Using the ANSI/ASQ Z1.4 2008 sampling plan, items are checked to ensure they meet purchase order requirements. We perform a thorough identity check, look for short shots, cracks and splits, loose or embedded particulate, flash, burn or blister marks, distortion, and air bubbles. A copy of our inspection criteria can be provided upon request.

There are items I can’t find in your catalog or website. Can you help me modify an existing product or find what I need for my project?

Yes. We welcome the opportunity to source and develop custom products. Please fill out a sourcing request form at or contact a member of our sales team today to get started. Minimum order quantities may apply depending on the project.

What credit cards do you accept?

We are pleased to accept Visa, Mastercard, Discover and American Express. Please be prepared to provide your credit card details every time you place an order. For your security, our ecommerce site does not store your credit card information. We take credit card fraud very seriously and employ many security methods to protect our customers’ information. Any fraud attempts are reported to the U.S. Government and FBI.

Does Qosina have a minimum order requirement?

In the design and development phase of a medical device or single-use system, Qosina understands the need to evaluate and test various components, in small quantities. That’s why we offer low minimum orders of $25, making it easier than ever before to get your high quality, single-use components.

We ask our customers to purchase a minimum $25 total order. Some items have minimum quantity order requirements.

Does your pricing include shipping charges?

Shipping charges are not included in our pricing. A shipping calculator, which provides an estimate for shipping costs for your items, can be found on our website in the shopping cart. All orders are shipped Ex-Works, Ronkonkoma, NY. This means that once your purchase is in the possession of your chosen carrier for delivery, all costs and risks involved in taking the goods from Qosina to your desired destination are the responsibility of you, the buyer. The carrier and buyer are responsible for damage or problems that arise during and after shipping.

Can Qosina accommodate an annual order and ship partial quantities?

Yes, we are happy to take volume orders and release quantities based on your schedule. You may set up a blanket order on our website or by contacting a member of our sales team.

How are your parts packaged?

Parts are secured within double-walled poly bags and then packaged in a double-walled carton.

Do you ship your products internationally?

Qosina ships to any country in the world that has trade relations with the United States of America, and we are pleased to partner with distributors in Japan and China. View our shipping policy, or contact a member of our sales team to learn more.

How will I know when my order has shipped?

You will receive a shipping confirmation email at the time your products are accepted by your chosen freight carrier.

How do I cancel an order?
