NMFC 37500 - Building Woodwork Group | Class N/A

Note 37502: NOTE-Where reference is made to this note, provisions apply on articles of foreign wood, other than Canadian wood or other than foreign birch, pine or spruce, not further finished than primed.

To find the correct freight class for your shipment:

1. Match your parts to the group: note if the shipment is architectural millwork (trim, casings, stair treads) or ships’ joiner pieces (bulkhead panels, cap rails), and confirm the specific item NMFC under this group before tender.
2. Protect long, delicate profiles: bundle by length with edge protectors, use a plywood top cap, and place bundles on skids with three stringers for pieces over 96 inches to avoid overlength handling and bending damage.
3. Control moisture and finish risk: wrap with poly, add desiccant for marine-bound freight, and mark Keep Dry; finished or veneered wood should be paper-interleaved and corner-guarded to prevent scuffs.
4. Document counts and orientation: list piece count, max length, and whether stacks are safe to top-load; label by project room or set (e.g., Stair 2 – Rail A) to speed jobsite receiving.

Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.

• Cleaner quotes, fewer reclasses: using the Building Woodwork group as your reference helps brokers and carriers zero in on the correct item record and class for wood components.
• Lower claim exposure: upgrading from loose bundles to crated or capped skids dramatically cuts edge crush and surface defects common with trim and moldings.
• Avoid avoidable accessorials: standardizing bundle lengths under 96 in and improving stackability reduces overlength and non-stackable fees, improving rate per CWT.
• Smoother installs, less detention: clearly labeled sets for millwork or joiner kits shorten unloading and staging at jobsites or shipyards, reducing wait time and redelivery risk.
