How to Determine Your Class
To find the correct freight class for your shipment:
- Identify construction and packaging: note if the shelter is wood-louvered (Stevenson style), metal, or molded composite, and whether it ships in a box, package, or crate to select the proper class within 85–200.
- Protect delicate louvers and vents: for assembled wooden shelters, use corner posts, cross-bracing, and a crate; for compact molded housings, a double-wall box with foam inserts or suspension packaging works well.
- Bag and secure small parts: place mounting brackets, screws, and grommets in a labeled pouch and fasten it to the interior panel so hardware doesn’t abrade painted surfaces in transit.
- Mark orientation and moisture needs: use “This Side Up” and “Do Not Stack” where relevant, and add desiccant plus a humidity indicator card for wood units to reduce swelling or finish damage.
Note: All classifications are subject to Item 170. Verify with official NMFC publications for the most current requirements.
Business Value
- Right class the first time: aligning material and packaging to the 85–200 range minimizes reclass fees and keeps LTL quotes accurate.
- Damage reduction on sensitive housings: proper bracing and cushioning prevent louver crush and roof vent deformation, lowering replacement and site-visit costs.
- Packaging choice as a cost lever: crating heavier or assembled shelters can qualify for a lower class within the range, improving freight rates without sacrificing protection.
- Faster procurement and installs: clear specs (material, size, packaging) streamline carrier approvals and keep weather station deployments on schedule.
