How to Calculate the True Cost of Manufacturing Apparel

How to Calculate the True Cost of Manufacturing Apparel

(FOB, EXW, shipping, duties, packaging, etc.)

Pricing your product right starts with knowing what it actually costs to make—and we’re not just talking about fabric and labor. The true cost of manufacturing apparel includes a mix of visible and hidden expenses that can seriously affect your margins if you don’t plan ahead.

Here’s a breakdown of what goes into the full cost of getting your product made, packed, and delivered to your warehouse or customer.


1. Start with the Base Production Cost

This is what your factory charges to physically make the product—often referred to as the unit cost.

It usually includes:

Labor

Raw materials (fabrics, trims, threads)

Cutting, sewing, finishing

Basic quality control

Make sure you confirm what is and isn’t included in the quote. For example, custom packaging or labeling may cost extra.

2. Understand FOB vs. EXW Pricing

Your manufacturer will usually quote based on either FOB or EXW terms. These determine who is responsible for transporting the goods and where the costs start.

FOB (Free on Board):
Price includes transport to the port and loading onto the ship. You handle freight, customs, and delivery from that point forward.
FOB is the most common for overseas production.

EXW (Ex Works):
Price only covers production. You’re responsible for everything after the goods leave the factory—local pickup, customs, and international freight.
EXW usually has a lower quote, but more backend costs.

3. Factor in Shipping and Freight

Once production is complete, you’ll need to get the goods from the factory to your destination.

Costs vary based on:

Air freight vs. sea freight (air = faster, sea = cheaper)

Volume and weight

Origin and destination country

Fuel surcharges and seasonal rates

Example: Shipping 500kg of socks from China to the U.S. by sea might cost $600–$900, while air freight could be $2,000+.

4. Add Duties and Import Taxes

Customs duties are charged based on:

The HTS (Harmonized Tariff Schedule) code of your product

The declared value of the shipment

The country of origin

Any applicable trade agreements or tariffs

You can calculate expected duties using tools like the U.S. Harmonized Tariff Schedule or services like SimplyDuty.

Pro tip: Some products have zero or reduced duties when manufactured in countries with trade agreements.

5. Include Packaging Costs

Packaging can be a big variable—especially for DTC brands focused on customer unboxing.

Costs may include:

Hang tags, woven labels, stickers

Polybags or recyclable sleeves

Custom printed boxes

Inserts, tissue paper, barcode stickers

Always clarify with your supplier if packaging is included in the quote or charged separately.

6. Inspection and Quality Control

In some cases, you’ll want to hire a third-party inspection service to check your goods before they ship, especially for large orders or new suppliers.

Inspection costs range from $150–$300 per day, depending on location and scope.

7. Warehouse and Final Delivery

Once your goods arrive, you’ll need to:

  • Pay customs clearance fees (usually handled by your freight forwarder)

  • Transport to your warehouse or 3PL

  • Possibly repack, relabel, or prep for final fulfillment

If you use a fulfillment partner, factor in storage and pick/pack fees too.


Example Breakdown (Per Unit)

Cost Component Estimate (per unit)
Production cost (FOB) $4.00
Sea freight & landing $0.80
Duties/tariffs $0.30
Packaging materials $0.50
Inspection + handling $0.20
Final warehouse fees $0.40
