NMFC 117555 - Pool or spa chlorinators in boxes | Class N/A

Note 117556: NOTE-Applies only on chlorinators used with salt water pools or spas to convert salt into sodium hypochlorite.

To find the correct freight class for your shipment:

1. Pack each chlorinator in a rigid, double-wall box with molded foam or air-cell cushioning around the housing, unions, and sensor leads; bag loose fittings to prevent scuffs.
2. If shipping power or control modules, place them in a separate inner carton and immobilize cords; keep the salt cell or feeder body upright and mark This Side Up.
3. Palletize multiple boxes in a single layer when possible to avoid crushing; no top load. Use edge protectors and two straps per box row for stability.
4. Do not co-pack with pool chemicals. Note Non-Hazmat chlorinator equipment on the BOL and include packaging photos to streamline claims if damage occurs.

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

• Non-hazardous listing helps avoid hazmat surcharges and speeds dock processing.
• NMFC reference for boxed chlorinators reduces reclass disputes and accelerates quoting.
• Stronger carton and cushioning standards cut breakage on housings, unions, and sensors.
• Consistent boxable format improves pallet density and can lower overall LTL costs.
