Importing sounds more intimidating than it needs to be for a first-time seller, mostly because the vocabulary (HS codes, Incoterms, customs brokers) is unfamiliar. The underlying process is fairly mechanical once you understand the sequence and who's responsible for what at each step.

The basic flow

Product leaves the factory → freight (ocean or air) to your country → customs clearance (duties/tariffs assessed and paid, based on the product's HS code and country of origin) → delivery to your warehouse or fulfillment center.

Duties and tariffs

Duties are calculated as a percentage of the product's declared value, based on its Harmonized System (HS) code — a standardized product classification used internationally. Rates vary significantly by product category and country of origin, and have been unusually changeable in recent years due to shifting trade policy — always check current rates for your specific product before finalizing pricing, rather than assuming last year's rate still applies.

Finding your product's HS code

Your customs broker or freight forwarder can help classify your product correctly, and getting it right matters: misclassification (even unintentional) can trigger unexpected duty assessments, delays, or penalties. If you're doing early research yourself, official government tariff-schedule lookup tools let you search by product description, but treat your own initial guess as a starting point to confirm with a licensed broker, not a final answer — a product can plausibly fit more than one HS code category, and the "obvious" one isn't always correct.

Who handles what: Incoterms

Incoterms (like FOB, EXW, DDP) define who's responsible for freight, insurance, and customs at each stage. As a new importer, DDP (Delivered Duty Paid) shifts the most complexity onto the supplier — you pay more, but you don't have to personally manage customs clearance. As you scale, FOB (Free on Board) often becomes more cost-effective once you have a freight forwarder/customs broker relationship to manage that complexity yourself.

Do you need a customs broker?

For anything beyond a very small, simple shipment, yes — a customs broker handles the classification and paperwork correctly, which matters because misclassification can mean unexpected costs or shipment delays. Many freight forwarders offer customs brokerage as part of their service (see How to Work With a Freight Forwarder and Customs Broker).

De minimis thresholds

Many countries have a "de minimis" value threshold below which small shipments can enter without duties or with simplified processing — useful to know if you're testing a product with a very small sample or trial shipment, though these thresholds and rules have also been subject to policy changes, so confirm the current threshold for your destination country rather than assuming an older figure still applies. This generally isn't a viable long-term strategy for regular commercial-volume imports, which are expected to go through standard customs clearance.

A worked landed-cost example

Say a supplier quotes $3.00/unit FOB (meaning you're responsible for freight and duties from that point) for an order of 2,000 units. Ocean freight for the shipment comes to $1,400 total, and the product's HS code carries a duty rate that, applied to the declared value, adds roughly $0.35/unit, plus a customs broker fee of $150 for the shipment. Rough per-unit landed cost: $3.00 (unit) + $0.70 (freight: $1,400 / 2,000) + $0.35 (duty) + $0.075 (broker fee: $150 / 2,000) ≈ $4.13/unit — noticeably higher than the $3.00 factory quote alone, which is exactly the gap that catches sellers who price off the factory quote without adding freight, duty, and broker costs. See Understanding Landed Cost, Margin, and Markup for the fuller concept, and Modeling Landed Cost for the complete component list.

Common mistakes first-time importers make

  • Pricing a product based on the factory's quoted unit cost alone, without adding freight, duty, and broker fees.
  • Assuming a duty rate quoted or estimated last year (or by a different seller in a different category) still applies to your specific product and current trade policy.
  • Not confirming who's responsible for customs clearance (via the chosen Incoterm) before the shipment departs, leading to confusion or delay when it arrives.
  • Underestimating total transit time, especially for ocean freight, when planning inventory levels and launch timing.

Troubleshooting: a shipment stuck in customs

A shipment can get held at customs for reasons including incomplete or inconsistent paperwork, a classification the customs authority disputes, a required certification/testing document that's missing, or a random compliance check. If this happens: work directly with your customs broker (this is exactly the situation they exist for), have your commercial invoice, packing list, and any required certificates ready to provide promptly, and avoid the temptation to under-declare value to reduce duties — this is illegal, creates its own serious risk, and is a common cause of exactly this kind of hold when discovered.

Checklist

  • I've identified my product's HS code with help from a customs broker, not just my own guess.
  • I've calculated full landed cost (unit cost, freight, duty, broker fees), not just the factory's quoted unit price.
  • I've confirmed which Incoterm applies and who's responsible for customs clearance.
  • I've checked current duty rates and trade policy for my specific product and country of origin before finalizing pricing.
  • I have a customs broker or freight forwarder relationship in place before my first shipment departs.
