Why is USP launching a new eCommerce site?
The new eCommerce site, called the USP Store, will improve the customer experience, giving users more self-service options. Easier online ordering, status tracking, dynamic pricing, an expanded online catalog, and enhanced account self-management to all improve the online experience for customers.

When will the new eCommerce site launch? 
The new USP Store launched on June 13, 2021. After this determined time, navigation to the current Store platform (iStore) will redirect customers to the new USP Store platform.

Will my existing Store (iStore) Account transfer over? 
Yes, iStore accounts that have been active within the past two years will automatically transfer over to the new USP Store. iStore users who also currently have an AccessPoint account will be able to access all accounts with AccessPoint Single Sign On. iStore users who currently do not have an AccessPoint account will receive an email from Access Point to re-establish a new password for the transferred account and to set up Single-Sign-On. Learn more about Account Transition using this guide.

What do I do if my company email has changed, and I need to change the email on my USP Store account? 
Once an account is created, the email address used to create the account cannot be changed for any reason. If your email changes while you are still associated with the same company, you will have to register a user with that existing business account. Reach out to the Administrators on the account to ensure the new user account is approved.

My iStore account was transferred over to the USP Store, but the oldest users on the business account is no longer able to access their email. How do I change the account Admin without their access? 
Each existing business account will transfer from the iStore to the USP Store with three default Administrator users on the account. Users should reach out to other account Administrators for updates. If there are extenuating circumstances where all Admin cannot be reached within the organization, contact Customer Service for assistance.

Our organization automatically pulls data from the Reference Standard Catalogs on the site to integrate into our own internal interface. Will this process change when the new USP Store goes live?  
No, the launch of the new USP Store will not interrupt or change existing processes with data on the site. Integration should continue uninterrupted.
Orders placed via the iStore or manually prior to the launch of the new USP Store site will process the same as today. These orders will be trackable via your transferred USP Store site account.

What happens with pending orders or orders in progress from the current Store (iStore) platform? 
Orders placed via the iStore or manually prior to the launch of the new USP Store site will process the same as today. These orders will be trackable via your transferred USP Store site account.

Can I still use the current Store (iStore) platform after the new eCommerce platform has launched? 
No. After launch of the new USP Store, navigation to the iStore will automatically redirect users to the new platform and the iStore will not be available to place orders. Should you have trouble accessing your transferred account or placing an initial order within the new platform, please contact Customer Service.

What is the difference between the Administrator and Buyer roles on my account? 
There are two types of roles for an account. Each account must first establish an Administrator. That Administrator will then authorize Buyers within each account. Both roles can log in to their USP Store account and search for products. Buyers can only complete orders and quotes and view account information once the Administrator has completed a one-time approval to set up the Buyer account. Each account can hold multiple Buyer and Administrator roles. Learn more about Administrator and Buyer roles with this guide.

How are user roles set up by default when my existing account transfers? 
The oldest user listed under the account will default to the account Administrator. All other users will default to the Buyer role. The Administrator can log in to the account and adjust Buyer/Administrator roles and will then be able to approve future users as Administrators or Buyers.

How do I change the email associated with my account? 
Once an account is created, the email used to register that account cannot be changed. Please register a new account under your business organization using the new email address.

How do I delete a Contact or a User on the account? 
Please contact Customer Service for assistance in removing contacts or account users.

How can I be assigned a Finance role on my account profile?
This role needs to be approved by your account administrator before you can proceed. Admins can assign any role as needed for your company. Please visit your account profile to contact your business account administrator.

Why are my contacts or addresses no longer saved under my account?
As part of the new features launch in June 2022, USP is also updating its backend systems to consolidate customer entered data (i.e., addresses, contacts, etc.) that has been previously saved on USP Store accounts.
If the saved information was not in a valid format (i.e., contained special characters such as an ampersand or hyphen) the information was not able to be consolidated and will have to be re-entered and/or saved to your account. We apologize for this inconvenience and greatly appreciate your understanding and action to update your account.


USP is pleased to announce that we have optimized the categories on our USP Store to make finding the products that you need more intuitive. Whether you are looking for reference materials to test your small molecule or biologic API’s or their related impurities, or reference materials to test your drug product’s excipients, we have grouped related products together for easier browsing. Of course, you can still choose to enter keywords in our search bar if you prefer, it’s up to you! To search- Begin typing in the search bar at the top of the home page and the platform will begin suggesting possible product matches after at least three letters are typed. A list of search results can also be obtained by hitting the “Enter” key. Products in the search results can be sorted alphabetically and by price.

How can I search for products? 
Begin typing in the search bar at the top of the home page and the platform will begin suggesting possible product matches after at least three letters are typed. A list of search results can also be obtained by hitting the “Enter” key. Products in the search results can be sorted alphabetically and by price.

Can I search by CAS number?
Yes. Users can search for products by name, CAS number, or catalog number.

If I spell a product incorrectly, will the system autosuggest alternative results? 
Not quite. Unlike a search engine, the USP Store search will not offer “did you mean” options for a misspelled product. The intuitive search helps to alleviate the need for this by beginning to suggest possible products once at least three letters or numbers are entered into the search bar, reducing the need to fully spell any product name.


Can I make a purchase on the USP Store in my local currency?
Purchases can be made using credit cards and electronic transfers by wire or ACH using USD, EUR, GBP, and CAD. The Chinese Yuan Renminbi (CNY/RMB) and Indian Rupee (INR) are ONLY available for wire payments at this time. Please note that you must have a USP Store account and credit terms with USP to make an online purchase and payment using wire/bank transfers.

What is the exchange rate used when making purchases in my local currency?
All pricing in the USP catalog is posted in USD and converted to the authorized currencies based on the conversion rate in place when a quote or order is created. Current conversion rates for these currencies can be found on the USP Store here.

Are there additional fees for making purchases in my local currency?
No, USP does not charge additional fees for using your local currency, however, you will be responsible for any wire/transfer fees charged by your bank.

Will I need to re-enter shipping addresses and payment information? 
No, once your account is transferred to the new USP Store platform, users will not need to re-enter shipping, billing, or payment information. This information will automatically transfer over and can be used for future orders.

Can I pay via credit card online?
Yes, you can pay with a credit card via the USP Store. All credit cards will be validated by the system with a $0 authorization charge. Please note that if an error is made in entering account information, the authorization will fail, and the card will have to be re-entered. Both account Administrators and Buyers can add or deactivate credit cards within their account.

Can I apply for credit at checkout?
Yes, the credit application link is available in the payments section during checkout. The link is also available under Account Info and Payment book, where customers can view approved credit or initiate a credit application.

How is my credit application processed? 
For credit line requests up to USD $10,000 or the equivalent, allow 48-72 hours for review and response. For credit line requests USD $10,000 or greater, additional information may be required such as audited financial statements. Processing and review time may take up to two weeks. Our analysis encompasses several factors including credit rating, payment history, projected sales volume of USP products and financial position. For information concerning the status of your application, please contact for assistance.

What are Favorites and how does this differ from the Cart? 
The Cart should be used for anything you’d like to purchase immediately. Products that you’d like to purchase later can be saved to a Favorites List for easy access to add to a future active cart. Products on a Favorites List remain on the list even after they’ve been added to an active cart for easy future reference.

I’m an Authorized Distributor; can I upload an Excel document for bulk ordering on the new platform? 
Yes. Once logged in to your USP Store account, click the “Quick Order” button at the top left. You’ll be able to download a template bulk-order document and then re-upload it to the system. The system will auto-populate the order and allow opportunity for manual adjustment before validating and adding all items to the cart with a single click. Please note that bulk orders are limited to 90 lines.

Does my order process and ship as soon as it is placed online? 
All orders route through a validation process after submission and before they are fulfilled. The USP Store system will prompt customers to upload relevant mandatory and optional documents as the final step before submitting the order. USP data stewards validate orders multiple times throughout each day, meaning your order processes more quickly when placed via the USP Store compared to placing an order over the phone or through email.

Can I order DEA controlled substances and dangerous goods online?
Yes! The new USP Store supports online order initiation for these controlled products. DEA controlled products must be purchased in a separate order (not mixed with non-regulated products) for any order shipping outside the United States. Required forms are indicated in the final step before submitting the order request, and you can check back to track the order or shipping.

What is the Save Cart feature? 
Saving a Cart allows you to save all items in a current active Cart to a separate Cart that can be checked out later. Saved Carts can be named, and accounts can hold multiple Saved Carts at once with different items. Carts remain saved on the account for 30 days.

What are acceptable forms of payment?
We accept credit cards and electronic transfers by wire or ACH. For customers in the United States, we also accept checks drawn on U.S. banks mailed to our Remittance address in New York. Refer to your invoice for bank account routing instructions.
All payments must include a customer account number and invoice number(s) to ensure timely and accurate processing in your account.  To verify receipt, please log into your account.

How can I apply the cash on my account toward an outstanding invoice?

After your Finance role has been approved, please visit your account profile, under the Invoice and Receipts tab, there will be an option to apply cash or credit on account to outstanding invoices.
