NMFC 138150 – Molds in Boxes/Crates | Class Density-Based

Note 138151: NOTE-Applies only on molds for casting, shaping or forming of plastics, other than by die casting, vacuum forming or injection molding.

To find the correct freight class for your shipment:

1. Confirm eligibility: shipment must be molds (block/brick hand molds; cast-iron bottle/glassware; metal molding NOI; pottery/ceramic; rubber or plastic molding per note) packed in boxes, crates, or packages.
2. Calculate density for Item 170: measure outer L×W×H of the packed piece (including crate/pallet), convert to cubic feet, then divide total weight by cubic feet to get lb/ft³.
3. Choose packaging by material: brace heavy cast-iron/steel molds in wood crates with blocking and banding; cushion ceramic molds; use moisture protection (VCI wrap) for iron; avoid heat for rubber/plastic tooling.
4. Mark documents clearly: list as Molds NOI under NMFC 138150, include counts and packaging type; if the freight is rubber or plastic molding product, verify applicability with Note, item 138151.

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

• Density-based rating rewards compact, heavy iron molds with lower classes, trimming LTL costs when packed efficiently.
• Single NMFC item covers diverse mold types, simplifying SKU management and minimizing reclassification risk across mixed shipments.
• Right-sized crates and internal bracing reduce damage claims on precision tooling, avoiding downtime and remake expenses.
• Clear density data speeds carrier quoting and inspections, improving tender acceptance and reducing surprise fees.
