GUDID storage and handling: lower bounds, upper bounds and special conditions
FDA’s acquired field table treats storage/handling type, numeric bounds and unit as related fields. Once a type is added, at least one bound and the relevant unit are conditional; a single exact value uses both bounds. Special-storage text has its own condition. Source these values from approved product information, rather than inventing a range from a product name.

Observed FDA field relationships
Which fields change this workflow?
FDA Data Elements Reference Table; acquired link labelled December 17, 2024. Entry conditions and edit rules below are transcribed from that version.
Indicates storage and handling requirements that are required for the device including temperature, humidity, and atmospheric pressure.
Recorded entry notes and format
Choose a value from the drop down LOV.
Conditions of the Storage and Handling Type are measured below as a range, with a Low Value and a High Value. More than one Storage and Handling Type can be added per device record.
Indicates the low value for storage and handling requirements.
Recorded entry notes and format
Enter a number for Low Value.
Must enter at least one value, Low or High but can enter both Low Value and High Value, if needed.
When Storage and Handling value is a range, this is the lower end of that range
When Storage and Handling value is not to fall below a minimum value, enter the number here
When Storage and Handling value is exactly a value, enter the value here and in Storage and Handling High Value
The low value can be up to 6 characters in length including leading zero, decimal and negative sign. Up to 4 numbers are allowed after the decimal.
Indicates the high value for storage and handling requirements.
Recorded entry notes and format
Enter a number for High Value.
Must enter at least one value, Low or High but can enter both Low Value and High Value, if needed.
When Storage and Handling value is a range, this is the higher end of that range
When Storage and Handling value is not to rise above a maximum value, enter the number here
When Storage and Handling value is exactly a value, enter the value here and in Storage and Handling Low Value
The high value can be up to 6 characters in length including leading zero, decimal and negative sign. Up to 4 numbers are allowed after the decimal.
Indicates any special storage requirements for the device.
Recorded entry notes and format
Enter any other storage conditions.
For devices kept at room temperature, or other standard conditions, input that information here.
Data type: Type: Alphanum.

Reference limits and edit-rule footnotes
Add = Addition of new data is allowed; Delete = Deletion of entered data is allowed; Edit = Editing of entered data is allowed; None = NO edit, add, or delete are allowed; NA = data element is not able to be changed directly; most are ‘auto-populated’ fields whose information depends on another data element
Note: The above do not apply if the device is “unlocked” for editing. For more information on “unlocking” device records for editing, please visit www.fda.gov/udi [6]
See 21 CFR 830.310 and 830.340 for required data elements. [7]
Most of the information presented here is applicable to GUDID HL7 SPL submissions, but there are some differences pertinent to each submission option. Please refer to the HL7 SPL Implementation package of files for additional details on HL7 SPL xml file submission option. [8]
These are dated FDA reference-table fields, not an automated legal applicability assessment or validated submission. The AccessGUDID download schema is different from the FDA HL7 SPL submission implementation package. No quarantined schema is used.
A mapping worksheet for this workflow
Use this checklist to gather your business or product details before speaking with a specialist. The items below explain what to record and suggest useful supporting documents. You can add your own answers in the editable project brief.
Choose the approved condition
Extract the relevant temperature, humidity, pressure or special-storage statement from controlled product information.
Useful evidence: Approved labels/IFU and validated storage specification.
Map the bound semantics
Separate minimum-only, maximum-only, bounded-range and exact-value cases using the source table’s entry rules; retain signs and units.
Useful evidence: Condition/type/bounds/unit worksheet and conversion rationale.
Reconcile exceptional conditions
Check conditional special text and unsupported formatting before upload; investigate disagreement between artwork and master data.
Useful evidence: Reviewed exception list and label-to-record reconciliation.
Work packages and dependencies
Conditional: GUDID storage and handling: lower bounds, upper bounds and special conditions — Review the controlled source evidence, prepare the field/relationship mapping described here, resolve exceptions and reconcile the intended records before confirming submission scope.
Questions for providers
How will you distinguish a minimum from a maximum or an exact value?
What controls prevent a missing bound from being interpreted as zero?
Which evidence supports the proposed storage conditions?
