Calculate True Cost Per Fire Starter Unit: Tariffs, Sea Freight, Insurance, and Warehousing
You see a price: $0.20 per fire starter from a Chinese factory. Good deal, right?
Then the shipment arrives. You add up everything you paid. The true cost is $0.47 per unit.
This happens constantly. Buyers forget the hidden costs. Or they assume the factory's EXW price includes more than it does.
Let us walk through the real calculation. Use this formula for every fire starter import.
The True Cost Formula
True Cost Per Unit = (Product Cost + Tariffs + Sea Freight + Insurance + Customs Broker + Trucking + Warehousing) ÷ Total Units
Miss any of these, and your margin disappears.
1. Product Cost (The Obvious One)
This is what the factory quotes. Usually EXW (Ex Works) or FOB (Free On Board).
What is included: The product and basic packaging inside the factory.
What is NOT included: Literally everything else.
Bulk Fire Starters quotes FOB or DDP. With DDP, most of the costs below are already included. But let us assume you are buying FOB to learn the full breakdown.
2. Tariffs and Duties (The Killer)
Fire starters imported from China to the USA fall under HTS code 3606.90. The tariff rate is currently 25% for most wax-based fire starters.
Pro tip: Some fire starters made from 100% wood (no wax) have different classifications. But our wood wool fire starters contain natural wax, so 25% applies.
3. Sea Freight (The Big Variable)
A 20ft container holds roughly 400,000 of our 20*65mm wood wool fire starters. Let us say you buy 50,000 units — about one-eighth of a container. You will share container space (LCL shipping).
If you buy a full 20ft container: $3,500 flat rate. That lowers the freight cost per unit significantly.
4. Marine Insurance (Cheap but Critical)
Do not skip this. Containers fall off ships. They get soaked with seawater. They sit on docks for months.
Cost: 0.5% to 1% of the product value plus freight.
Without insurance: You lose $10,000 if the ship sinks.
5. Customs Broker Fees (Mandatory)
You cannot clear US customs yourself. You need a licensed broker.
Typical fees:
Customs entry filing: $75–125
ISF filing (Importer Security Filing): $25–50
For one shipment: ~$150
6. Trucking (Port to Your Warehouse)
The port is not your warehouse. You need a drayage truck.
LA port to a warehouse 50 miles away: $350–500
Longer distance (e.g., LA to Denver): $1,500–2,500
7. Warehousing (The Forgotten Cost)
Your product sits somewhere before going to retailers. Even if you own the warehouse, you have costs: rent, labor, insurance.
For 50,000 units (4 cubic meters = 141 cubic feet): $70–140 per month
If your inventory sits for 3 months, that is $210–420 added to total cost.
What About Smaller Orders?
For trial orders under 10,000 units, sea freight does not make sense. Air freight is faster but expensive.
At that volume, buy locally or from a distributor. Or ask Bulk Fire Starters about our small-batch DDP air service — we consolidate small orders from multiple buyers into one air shipment to lower your cost.
Why This Matters for Bulk Buyers
If you are a retailer, a campground, or a distributor, your margin depends on true cost, not the factory quote.
