What UDI Compliance Requirements Apply When Purchasing a Pressotherapy Machine?

When our team ships pressotherapy units overseas, we often hear the same question from buyers: “What about UDI compliance ¹?” It’s a valid concern. A single missing barcode or database registration can hold your inventory at customs. It can also trigger FDA enforcement actions down the road.

When purchasing a pressotherapy machine, you must ensure the device bears a valid Unique Device Identifier (UDI) on its label and packaging in both human-readable and machine-readable formats. The manufacturer must also register the device in the FDA’s GUDID database before the product enters the U.S. market. Your specific obligations depend on device classification and whether you are private labeling.

This guide breaks down exactly what you need to know FDA’s GUDID database ². We’ll cover FDA labeling requirements, private label obligations, how to verify your Chinese supplier’s compliance, and the real risks of non-compliance. Let’s get started.

How do I ensure my imported pressotherapy machine meets all FDA UDI labeling requirements?

Our export team has seen shipments delayed at U.S. ports because buyers didn't verify UDI compliance before placing orders. The frustration is real. But the solution is straightforward once you understand the requirements.

To ensure FDA UDI compliance, verify that your pressotherapy machine label includes a Device Identifier (DI) and Production Identifier (PI) in both plain-text and AIDC barcode format. Confirm the manufacturer has submitted device data to the FDA's GUDID database before shipment. For reusable devices, check that the UDI is directly marked on the device itself.

Understanding the Two Parts of a UDI

A UDI is not just a barcode. The Device Identifier (DI) ³ identifies the labeler and the model/version of a device. The DI is a required component and considered to be the static portion of the UDI, meaning it is the same for all instances of the product model/version. The Production Identifier (PI) ⁴ identifies one or more variable characteristics, such as manufactured date, expiration date, lot number, or serial number. The PI is considered to be the dynamic portion of the UDI, meaning the PI value changes according to the production controls.

When combined, the device identifier and the production identifier form the full-length UDI. The DI is always first and is followed by the PI if it has a value.

Label Format Requirements

The FDA requires that the UDI be prominently displayed on the device's label and packaging in both human-readable and machine-readable formats, such as barcodes or QR codes. AIDC barcode format ⁵ For certain devices, like those intended for re-use or that must be sterilized, the UDI must be directly marked on the device itself.

This dual-format requirement is not optional. Pressotherapy machines used in clinical settings often undergo multiple treatment cycles. If your device falls into this category, you need direct marking.

Key FDA Labeling Requirements for Pressotherapy Machines

Verifying GUDID Registration

The Global Unique Device Identification Database (GUDID) contains key device identification information submitted to the FDA about medical devices that have Unique Device Identifiers (UDI). The FDA is establishing the unique device identification system to adequately identify devices sold in the U.S.- from manufacturing through distribution to patient use. You can use AccessGUDID ⁶ to search for specific medical devices or download all the GUDID data at once.

Before you finalize any purchase, search the AccessGUDID portal. Enter the device identifier. If nothing appears, the manufacturer has not completed registration. Do not accept delivery until this is resolved.

Getting UDI Numbers from Accredited Agencies

GS1 ⁷ is an UDI issuing agency or Entity for many UDI regulations worldwide, including in the European Union, Brazil, China, Egypt, Saudi Arabia, Singapore, South Korea, Taiwan, Türkiye and the USA. This means that manufacturers or labelers can use the GS1 standards to comply with UDI requirements from these jurisdictions.

Ask your supplier which issuing agency they use. GS1 and HIBCC ⁸ are the most common. The issuing agency assigns the DI portion. Your supplier should provide documentation confirming this.

What are my specific UDI obligations when private labeling a beauty machine from an OEM supplier?

Many of our clients want their brand on the product. They ask us to manufacture under their label. This changes everything regarding UDI responsibility. The name on the label determines who owns the compliance burden.

When private labeling a pressotherapy machine, you become the "labeler" under FDA regulations and assume full UDI responsibility. You must obtain your own Device Identifier from an FDA-accredited issuing agency, create a GUDID account in your company name, and submit all required device data. The OEM supplier's UDI cannot be used on your private-labeled product.

Who is the "Labeler" Under FDA Rules?

FDA regulations state that GUDID submissions and general UDI compliance are the responsibility of the "device labeler," which they define as: …Any person who causes a label to be applied to a device, or who causes the label of a device to be modified, with the intent that the device will be commercially distributed without any subsequent replacement or modification of the label. …in most instances, the labeler would be the device manufacturer, but the labeler may be a specification developer, a single-use device reprocessor, a convenience kit assembler, a repackager, or a relabeler.

If your company name appears on the product label, you are the labeler. Full stop.

Private Label UDI Requirements

Reprocessors of single use medical devices, remanufacturers, Own Brand/Private Labelers shall create their own, new UDI for the reprocessed, remanufactured, or relabeled medical device which will replace the OEM's UDI where it exists.

This IMDRF guidance makes it clear: you cannot simply use the OEM's existing UDI. You must generate your own.

Steps to Establish Your Own UDI as a Private Labeler

Maintaining OEM Records

Reprocessors of single use medical devices, remanufacturers, Private (Own Brand) Labelers shall retain record of the Original Equipment Manufacturer's (OEM) UDI.

Even though you create a new UDI, you must keep records linking your product to the OEM's original identification. This supports traceability if issues arise.

Working with Your OEM Supplier

The company listed on the label is required to apply for the GTIN from the issuing agency and to apply for the GUDID account from the FDA. The FDA will not give another company the account–even if you are outsourcing the labeling creating and control to that company. If you private label you will need to give the prefix numbers to your supplier and you will need to enter information in the GUDID.

Our team at the factory can produce labels with your UDI codes. But you must provide those codes to us. We cannot obtain them on your behalf because the GUDID account must be in your name.

Complaint File Responsibilities

Since the distributor's name is on the product, the distributor will need to assign the "DI" portion of the UDI number. Finally, the distributor is responsible for verifying that the US Agent is maintaining distribution records and maintaining the data in the GUDID.

Private labeling also means handling complaints. Your U.S. Agent or complaint file establishment must link complaints back to your UDI. This creates a closed loop for adverse event tracking.

How can I verify that my Chinese manufacturer is correctly implementing UDI tracking on my order?

We understand the anxiety. You're halfway around the world from the factory. You can't inspect every label yourself. But verification doesn't require a plane ticket. It requires a systematic approach.

To verify Chinese manufacturer UDI compliance, request copies of their issuing agency membership certificate, sample labels showing both plain-text and AIDC formats, and confirmation of GUDID submission with the published record link. Cross-check the Device Identifier against the AccessGUDID public database before approving production. Include UDI compliance clauses in your purchase contract.

Pre-Production Verification Checklist

Before production starts, collect the following from your supplier:

Checking the Public Database

The Global Unique Device Identification Database (GUDID) contains key device identification information submitted to the FDA about medical devices that have Unique Device Identifiers (UDI). In collaboration with NLM, the FDA has created a portal, called AccessGUDID, to make device identification information in the GUDID available for everyone.

Open AccessGUDID in your browser. Enter the Device Identifier from the sample label. The record should display manufacturer name, device description, and production identifier flags. If the search returns nothing, do not proceed with the order.

What the GUDID Record Should Show

By capturing standardized device information linked to each Unique Device Identifier (UDI), the GUDID not only supports regulatory compliance but also enhances postmarket surveillance, adverse event reporting, and recall management.

Review the GUDID record for accuracy. Check that the device description matches what you ordered. Verify the production identifier flags align with your label requirements (lot number, expiration date, serial number).

Addressing Discrepancies

If it appears the listing discrepancy is real, you will need to update your device listings and/or your GUDID account, as appropriate. If your company does not yet have a GUDID account, you can register for one.

If you find errors, halt production. Work with your supplier to correct the GUDID submission. The FDA now actively monitors for discrepancies and sends letters to registrants when device listings don't match GUDID data.

In-Production Quality Control

Our quality team performs in-line label checks. But you should request photographic evidence. Ask for:

• Close-up images of printed UDI barcodes
• Scan verification reports showing barcode readability
• Direct marking photos (if applicable for reusable devices)

Contractual Protections

Include specific UDI requirements in your purchase agreement:

1. Supplier warrants UDI compliance with 21 CFR 801.20 ¹⁰
2. Supplier will provide GUDID submission confirmation before shipment
3. Supplier will correct any UDI deficiencies at no additional cost
4. Buyer may reject shipments without compliant UDI labeling

This creates accountability. It also demonstrates due diligence if regulators ever question your supply chain.

What risks do I face if my pressotherapy equipment arrives without the proper UDI identifiers?

We've seen it happen. A buyer rushes an order. The goods arrive at the port. Customs flags the shipment. Weeks pass. Costs mount. This scenario is entirely preventable with proper verification. But if it happens, you need to understand the consequences.

If pressotherapy equipment arrives without proper UDI identifiers, you face FDA enforcement actions including import detention, product seizure, civil monetary penalties, and potential injunctions. Non-compliant devices are considered misbranded under federal law. Beyond regulatory penalties, you risk supply chain disruption, reputational damage, and inability to fulfill customer orders.

FDA Enforcement Authority

The FDA has announced that non-compliance with Unique Device Identification could be considered misbranding. This paves the road for serious penalties. Potential enforcement actions for violations of UDI requirements include seizure, injunction, and civil and criminal penalties.

This is not theoretical. The FDA has teeth, and they use them.

Types of Enforcement Actions

The FDA works with the U.S. Marshals Service and other federal authorities to seize misbranded, adulterated, illegally imported, and other violative products when necessary to prevent their distribution or sale. Here, too, the FDA's seizure efforts will often be accompanied by other enforcement efforts as well.

The Warning Letter Process

Warning letters from the FDA identify specific violations and notify recipients that they must take appropriate responsive action in order to avoid further enforcement action by the FDA. Warning letter recipients have a deadline to respond; and, once the deadline passes, the FDA will "check[] to ensure that the company's corrections are adequate."

If you receive a warning letter, you have a narrow window to respond. Inadequate responses lead to escalation.

Civil Monetary Penalties

Civil monetary penalties (CMPs) have a maximum penalty of $15,000 per violation, not to exceed $1 million for all violations in a single proceeding.

These penalties add up quickly. A shipment of 100 non-compliant units could theoretically expose you to significant financial liability.

Impact on Premarket Applications

If your fda udi registration data is inconsistent with your actual product labeling, you're not just looking at a minor typo – you're looking at a potential "adulterated or misbranded" device charge.

For companies with devices requiring 510(k) clearance, UDI non-compliance can delay approval of premarket applications. This creates a cascading effect on your product launch timeline.

Federal Contract Implications

Federal agencies consider compliance status when awarding contracts. If your company sells to government healthcare facilities, UDI non-compliance can disqualify you from procurement opportunities. This affects long-term revenue, not just a single shipment.

Practical Business Consequences

Beyond regulatory penalties, consider the operational impact:

• Customer commitments: You cannot ship to clinics waiting for equipment
• Cash flow: Tied-up inventory means tied-up capital
• Reputation: Compliance failures spread through industry networks
• Future sourcing: You may need to find a new supplier entirely

Remediation Costs

If you receive non-compliant goods, remediation is expensive. Options include:

1. Return shipment to manufacturer for relabeling
2. Relabel in the U.S. (if you become registered as a relabeler)
3. Destroy non-compliant inventory

None of these are cheap. Prevention is always less expensive than correction.

Conclusion

UDI compliance is not optional. It is a regulatory requirement that protects your business, your customers, and ultimately the patients who use pressotherapy equipment. Verify before you buy. Check the GUDID database. Review sample labels. Build compliance into your supplier contracts. The time you invest upfront will save you from costly enforcement actions and supply chain disruptions down the line.
