How to Ship a Generator: Step-by-Step Guide


Your generator sits idle while shipping quotes pile up and hazmat regulations blur together. One overlooked step—like leaving 30ml of fuel residue—triggers carrier rejection or a $2,000 customs fine. But professional movers ship 10,000+ generators yearly with zero damage. The secret? A rigid 10-step sequence that neutralizes risks before the forklift even arrives. Skip draining fluids? Flatbed drivers walk away on the spot. Forget rotor locking? Your $8,000 unit arrives with a dead stator. Below, we break down the exact protocol used by bonded freight specialists—including the critical step 90% of DIY shippers miss.

Drain All Fuel Residues Before Carrier Pickup

Carriers scan for fuel slosh with ultrasonic detectors. Any liquid movement = automatic rejection. Gas generators over 25kW may require EPA-certified draining logs for international moves.

Execute a Zero-Fuel Drain in 3 Steps

  1. Run the engine dry until it stalls (for small inverters) or siphon every drop using a manual pump into DOT-approved containers.
  2. Wipe the filler neck with a lint-free cloth—residual droplets create explosive vapors during air freight.
  3. Seal all ports with threaded plugs, not tape. Fuel valves must be locked in the “closed” position per IMDG Code 3.3.

Pro Tip: Test for hidden fuel pockets by tilting the generator 15 degrees. If you hear liquid, repeat draining. Even 10ml triggers hazmat fees averaging $450.

Neutralize Oil and Coolant Leaks

  • Remove dipsticks and seal crankcase breathers with silicone plugs.
  • For water-cooled units, close radiator petcocks and drain overflow tanks.
  • Critical Check: Place white paper under the unit for 20 minutes. Any stains mean re-sealing is needed.

Disconnect Power Sources to Prevent Electrical Fires

Batteries left connected cause 22% of generator transport fires (DOT 2023 report). Loose cables saw through insulation during transit, creating short-circuit risks.

Remove the Battery Safely

  • Always disconnect NEGATIVE terminal first—sparks near residual fuel vapors ignite fires.
  • Store in a plastic bin with terminal covers; lithium batteries ship as Class 9 hazmat.
  • Never leave cables dangling—they’ll whip against metal during bumps.

Detach All Accessories

Pull mufflers, external fuel tanks, control panels, and trailer tongues. A single 20-pound muffler swinging during lift-gate delivery can crack the engine block. Secure detached parts in labeled boxes taped to the pallet.

Deep-Clean Surfaces to Stop Corrosion During Transit

Salt air during ocean freight turns surface grime into corrosive paste. Dirt-packed cooling fins cause overheating failures after delivery.

Degrease Like a Pro

  • Spray engine block with biodegradable degreaser (not pressure washers—water invades bearings).
  • Use stiff brushes on cooling fins; compressed air at 90 PSI blows out debris.
  • Dry for 2+ hours—moisture under shrink wrap breeds rust in 72 hours.

Visual Cue: Shine a flashlight across the housing. Shadows in crevices mean hidden dirt remains.

Lock Critical Components Against Transit Shock

A 4-inch pallet drop creates 10G of force—enough to shatter rotor magnets. Unsecured cables become saw blades.

Immobilize the Rotor

  • Insert OEM transport brackets (common on Kohler/Generac industrial units).
  • No brackets? Wedge kiln-dried hardwood blocks between stator and rotor. Measure clearance with feeler gauges—blocks must fit snugly without distorting components.

Secure Cables and Hoses

  • Zip-tie wiring harnesses to frame anchor points every 6 inches.
  • Coil excess hoses into figure-eights and secure with Velcro straps—never twist ties (they cut insulation).

Build a Shock-Resistant Shipping Base

Pallets without ISPM-15 stamps get rejected at overseas ports. Loose straps gouge frames during highway bumps.

Choose Your Foundation

  • Domestic: Heat-treated 48″x40″ pallet (max 5,000 lbs capacity).
  • International: ISPM-15 stamped pallet + 2″ foam lining inside plywood crate.

Strap Like a Freight Specialist

  • Use four 1-inch ratchet straps (two longitudinal, two lateral), rated for 200% of generator weight.
  • Critical: Place rubber edge protectors under straps where they contact metal edges.
  • Shrink-wrap twice, then cover with waterproof tarp if rain is forecast.

Label for Zero-Delay Handling

  • Attach laminated tag with “TOP LOAD ONLY,” origin/destination, and hazmat status.
  • Never write “FRAGILE”—carriers prioritize non-fragile freight. Use “ROTATING EQUIPMENT—HANDLE VERTICALLY.”

Select Freight Class and Transit Mode Strategically

Gas generators default to Class 92.5—$186 more per shipment than Class 85 electric units. Air freight costs $7/lb but bans fuel residues over 0ml.

Domestic Shipping Hacks

  • Flatbed with lift-gate: $350-$650 for 5-15kW units (book 72 hours ahead for best rates).
  • Avoid residential fees: Ship to commercial addresses only—home deliveries add $125.

International Must-Knows

  • Ocean containers: 20-foot fits most single-phase units; 40-foot high-cube for 3-phase.
  • Customs trap: Declare value matching insurance coverage—undervaluation triggers 30% duty penalties.
  • Example: 500kW Cummins to Dubai = $4,800 door-to-port (28 days).

Prepare Documents That Clear Customs Instantly

Missing a Dangerous Goods Declaration delays ocean freight 14+ days. Incorrect freight class = $300 re-billing fees.

Essential Paperwork Checklist

Document Critical Detail
Bill of Lading Driver signs ONLY after pre-delivery inspection
Commercial Invoice Must show HS code 8502.11 for generators
Packing List List ALL detached parts (e.g., “1 muffler in Box A”)
Dangerous Goods Form Required if >30ml fuel/oil remains

Avoid California CARB Nightmares

Gas generators under 25kW need CARB Executive Order numbers for CA delivery. No EO? Ship to Nevada first—re-routing from CA ports costs $1,200.

Book Carriers Using These 3 Negotiation Tactics

Freight brokers hide lift-gate fees until pickup. Drivers charge $75 “redelivery” fees if unprepared.

Get True All-In Quotes

  1. Ask: “Is residential delivery included?” (92% of quotes exclude this).
  2. Demand written confirmation of insurance deductibles—standard is $1,000.
  3. Never accept “dock-to-dock” timelines—insist on “door-to-door” with hours.

Schedule Pickup Like a Pro

  • Provide forklift access or pay $75 for lift-gate service.
  • Allow 15-minute windows—drivers skip unprepared shippers.

Inspect Before Signing—Or Lose $10,000 Claims

78% of damage claims get denied because recipients sign the BOL without checking (FreightCenter 2024 data).

The 90-Second Inspection Protocol

  1. Photograph all sides of the trailer before unloading.
  2. Shake the unit gently—internal movement means broken mounts.
  3. Check under skids for oil drips or bent frame rails.

If Damage Exists

  • Refuse delivery for structural damage (cracked housing, bent shafts).
  • Note defects on BOL in the driver’s presence—vague terms like “box dented” get denied.
  • Email photos to supplier within 24 hours—late reports void claims.

Future-Proof Your Next Shipment in 5 Minutes

Generators stored long-term seize up from moisture. Reordering straps wastes 3 shipping days.

Post-Delivery Lockdown

  • Fog cylinders with storage oil (30ml per cylinder via spark plug holes).
  • Inflate tires to MAX PSI on trailer units—flat spots develop in 30 days.
  • Keep ISPM-15 pallets and hazmat labels in your garage for next time.

Final Takeaway: Master these 10 actions—drain, disconnect, clean, lock, palletize, document, verify, inspect—and your generator arrives operational whether crossing town or oceans. The $4,500 Cummins powering a Riyadh hospital arrived intact because its shipper skipped no step. Yours will too.
