NMFC Updates: A Practical Guide for LTL Shippers
What LTL shippers need to know about the 2025 NMFTA NMFC changes: a new 13-tier density scale, ClassIT+, and how to verify class before requesting a rate.
NMFC updates can change commodity descriptions, item numbers, subprovisions, packaging requirements, rules, and freight classes. The practical response is not to memorize every docket. It is to verify the current NMFC content for the planned ship date and to understand where a proposed change sits in the update cycle.
That distinction matters. A docket contains proposals. A disposition bulletin reports what was approved, modified, or disapproved. A supplement publishes the updated NMFC data, and its effective date determines when those changes apply.
The current NMFC update picture
The July 19, 2025 changes under Docket 2025-1 were a major modernization of the classification system. NMFTA expanded the standard density scale used for many commodities and consolidated numerous listings. It also launched ClassIT+ as the home for current NMFC data.
Those changes were not the end of the update process. Supplement 2025-2 became effective December 6, 2025. In 2026, Docket 2026-1 moved through public review and a disposition bulletin. NMFTA reported that the resulting changes would appear in Supplement 1 to NMF 100-AZ, issued April 24, 2026 and effective May 23, 2026.
For a shipper, the important date is the effective date of the applicable supplement. A proposal in a docket may be changed or rejected before it reaches that point. Do not update a freight class merely because a proposed item appears in a docket.
How an NMFC change becomes effective
NMFTA describes a recurring data-update lifecycle. Understanding the stages prevents two common errors: treating a proposal as final and continuing to use superseded content after a supplement takes effect.
Proposal and docket
Classification changes begin as proposals. A docket is the collected set of proposals scheduled for review. It shows what may change and gives the industry an opportunity to examine the supporting analysis and provide feedback.
A docket is an early-warning document. It is useful for finding items your business may need to monitor, but it is not the final classification instruction.
Review, vote, and disposition bulletin
The Freight Classification Development Council reviews and votes on docket proposals. The disposition bulletin records the outcome. A proposal may be approved as written, approved with changes, or disapproved.
At this stage, shippers can compare the outcome with the proposal and begin preparing systems, product records, and customer communications. The disposition still needs to be carried into the supplement before the updated data becomes effective.
Supplement and effective date
The supplement publishes the approved and modified NMFC data. Its issue date and effective date are not the same thing. The interval gives users time to prepare before the new content governs classification.
Use the effective date to decide which version applies to the planned shipment. If a quote is prepared before an effective date but the shipment will be tendered afterward, verify the item again for the actual ship date.
Use ClassIT+ for current and upcoming content
ClassIT+ provides several views that serve different purposes:
- Current NMFC search shows effective data.
- Coming Soon shows data that has been issued but is not yet effective.
- What’s New shows data that has changed and is effective.
- Public docket and disposition resources show proposed changes and their outcomes.
- Supplement resources provide the published data update.
NMFTA’s search documentation also allows current content to be filtered by date, date range, supplement, or public docket. Use the “as of” date that matches the planned shipment when timing matters.
Do not rely on a cached class from a product master, an old bill of lading, a spreadsheet, or a third-party class chart without checking whether the underlying NMFC item is still current. Historical records are useful evidence, but they are not proof that the same provision remains effective.
What can change in an update
An NMFC update is not limited to the class number. Review the entire applicable entry because a supplement may change:
- The commodity description or scope
- The NMFC item number
- A subprovision or density condition
- Notes, rules, and cross-references
- Minimum packaging requirements
- Whether an item has been consolidated, canceled, or referred elsewhere
- The assigned class
The 2025 modernization made density the primary factor for many commodities without significant handling, stowability, or liability concerns. It did not make density the only classification input. Commodity-specific provisions and the other transportation characteristics still matter where the current item says they do.
A density calculator is therefore a planning tool, not a replacement for the current NMFC entry. First identify the commodity and item. Then apply the density, package, and other conditions in that entry.
Build an internal update routine
A small repeatable process is more reliable than a large one-time cleanup.
Keep a classification record for each commodity
For each recurring product, retain:
- Specific commodity and manufacturer descriptions
- Product function, materials, and complete-versus-component status
- Photos, model references, or supporting product literature
- Package type and shipping form
- Packaged dimensions and weight
- NMFC item number, subprovision, and class
- The source and effective date used for the decision
- Notes, rules, exceptions, and packaging references reviewed
- The name or role of the person who verified the result
This record makes it easier to identify which products may be affected when a docket, disposition bulletin, or supplement is published.
Review upcoming changes before the effective date
Use Coming Soon and the disposition bulletin to identify approved changes that will affect frequently shipped items. Update product data, quote procedures, and bill-of-lading templates in time for the effective date.
Do not overwrite the current value too early. Keep the present and future classifications tied to their effective dates so shipments are not assigned a new provision before it applies.
Recheck changed or ambiguous items
When an item is canceled, consolidated, referred to another item, or rewritten, read the new entry in full. Do not assume the replacement applies to every product that used the former item.
If two items appear plausible or a product no longer fits the revised description, gather the manufacturer, function, construction, package, and shipping-form evidence. Resolve the question through a qualified classification resource instead of choosing the lower class or carrying the old item forward.
Update shipping documents and systems together
A corrected product master does little good if the quote screen or bill-of-lading template still inserts old data. Update each place that stores or transmits the commodity description, NMFC item, subprovision, class, and package information.
NMFTA’s Item 250100 guidance says bill-of-lading descriptions must match the tariff and include the article, package, special markings, exceptions, NMFC item number, subprovision, and class. It also confirms that a carrier may verify shipment weight and dimensions.
Pre-quote NMFC update checklist
Before requesting an LTL rate:
- Identify the planned ship date.
- Search effective NMFC content for that date.
- Check What’s New for recently effective changes.
- Check Coming Soon if the shipment date falls after an announced effective date.
- Read the complete item, subprovision, notes, rules, and package requirements.
- Confirm the packaged dimensions and weight of every handling unit.
- Record the source and effective date used for the classification.
- Make the quote details and bill of lading match the physical freight.
- Reverify the item if the commodity, package, dimensions, weight, or ship date changes.
