A charge reading TFS*FISHERSCI ECOM CHI on your credit card or bank statement is an online order placed through Fisher Scientific, the laboratory-supply business owned by Thermo Fisher Scientific Inc. “TFS” is Thermo Fisher Scientific, “ECOM” flags an e-commerce order, and “CHI” is a code for the processing location. If you or someone with access to your card bought lab supplies, this is a normal purchase descriptor. If not, it’s worth looking into, because Fisher Scientific sells almost exclusively to businesses and institutions.

How to Check Whether the Charge Is Yours
Rule out the ordinary explanations first. A family member, roommate, or coworker with access to the card may have placed an order. If the card is tied to a business or expense account, check with whoever else uses it. Search your email inbox for order confirmations from fishersci.com or thermofisher.com; a legitimate purchase almost always leaves one. You can also log in to the Fisher Scientific or Thermo Fisher account linked to the order and compare the invoice against the amount on your statement.

Fake Sites That Impersonate Thermo Fisher
Thermo Fisher has flagged an ongoing problem with fraudulent look-alike domains registered by unauthorized third parties. These typosquatted addresses mimic the company’s name with slight misspellings and are used to impersonate employees, deceive customers, and solicit payments or sensitive information. The company publishes a running list on its Threat Alerts page; between January 2025 and May 2026, more than 50 fraudulent domains were identified, including THERMOFISHSER.COM, THERRMOFISHER.COM, and THERMOFISHER.TECH.6Thermo Fisher Scientific. Threat Alerts Anyone who entered card details on a fake site could see charges appear later under a real Thermo Fisher descriptor.
If you suspect that happened to you, Thermo Fisher’s corporate site has a Fraud Reporting Form, and it says an investigator will follow up.7Thermo Fisher Scientific.

Disputing an Unauthorized Charge
If you cannot connect the charge to a real purchase, call your card issuer at the number on the back of the card. To preserve your full rights under the Fair Credit Billing Act, follow up in writing to the issuer’s billing-inquiry address within 60 days of the statement date on which the charge appeared.9Consumer Financial Protection Bureau. How Do I Dispute a Charge on My Credit Card Bill Include your name, account number, and a description of the charge, and keep copies of what you send.
Once the issuer receives your written notice, it must acknowledge the dispute within 30 days and complete its investigation within 90 days.10FTC. Using Credit Cards and Disputing Charges During that period you may withhold payment on the disputed amount, and the issuer cannot report it as delinquent or try to collect on it. Federal law caps a consumer’s liability for unauthorized credit card charges at $50, and many issuers waive even that.11Investopedia. Fair Credit Billing Act
