Starting an importation business requires a legal business entity, an importer number from U.S. Customs and Border Protection (CBP), reliable overseas suppliers, and enough capital to cover inventory, shipping, and duty payments before your first sale. The barrier to entry is relatively low compared to many businesses, but the learning curve around customs procedures, tariff classification, and supplier vetting is steep enough that preparation matters more than speed.
Choose a Product and Research Demand
Before registering anything, you need a product category worth importing. The best import products share a few traits: strong domestic demand, a meaningful price gap between the foreign manufacturing cost and the U.S. retail price, manageable shipping weight and volume, and no complex regulatory barriers like FDA approval or EPA certification (at least for your first product).
Start by browsing wholesale marketplaces like Alibaba, Global Sources, or Made-in-China to see what categories of goods are widely manufactured overseas and at what price points. Then compare those prices against what similar products sell for on Amazon, in retail stores, or through wholesale distributors in the U.S. Your margin needs to cover not just the product cost but also shipping, customs duties, insurance, warehousing, and marketing. A rough rule: if the landed cost (product plus all shipping and duty charges) is less than 30% to 40% of the expected retail price, you have room to build a viable business.
Check whether your product requires any special permits or agency approvals before it can enter the U.S. Food, supplements, cosmetics, electronics, children’s products, and agricultural goods all have additional requirements from agencies like the FDA, CPSC, or USDA. These aren’t dealbreakers, but they add time, testing costs, and paperwork you should factor in early.
Register Your Business and Get an Importer Number
You’ll need a formal business entity to operate as an importer. Most importers register as an LLC or corporation with their state, then obtain an Employer Identification Number (EIN) from the IRS. The EIN doubles as your importer number when filing customs paperwork, so it serves two purposes at once. If you don’t have an EIN or a business entity, you can technically use your Social Security number or request a CBP-assigned number, but operating under a registered business gives you liability protection and looks more credible to suppliers and freight companies.
To formally register with CBP, complete CBP Form 5106 and submit it at the entry branch of any CBP port of entry. This form establishes your identity in the customs system so you can file entry paperwork when shipments arrive. You must file CBP entry forms within 15 calendar days of your shipment arriving at a U.S. port, and your importer number goes on every one of those forms.
Find and Vet Overseas Suppliers
Finding a manufacturer is easy. Finding a reliable one takes more effort. Online wholesale platforms list thousands of factories, but a listing alone tells you nothing about product quality, production capacity, or business legitimacy.
Before placing a large order, verify your supplier across several dimensions. Confirm they’re a genuine legal entity by checking local business registries or chambers of commerce in their country. Verify that their trading address is real and active. Ask for proof of quality certifications like ISO 9001, which indicates standardized manufacturing processes. If the supplier claims third-party certifications, request the certificate numbers so you can verify them independently.
For your first order, request product samples before committing to a bulk purchase. Once you’re ready for production, consider hiring a third-party inspection company to check quality at key stages. Services like Intertek and SGS offer inspections at multiple points: initial production checks to verify raw materials before manufacturing begins, during-production checks to catch problems early, and final random inspections after goods are packed to verify safety, quantity, workmanship, sizing, and packaging before the shipment leaves the factory. These inspections typically cost a few hundred dollars per visit and can save you thousands in rejected or unsellable inventory.
Red flags to watch for include suppliers who refuse video calls or factory tours, prices dramatically below competitors (suggesting corner-cutting on materials), inconsistent communication, and reluctance to provide references from other buyers.
Understand Customs Duties and Tariff Classification
Every product imported into the U.S. is assigned a classification code under the Harmonized Tariff Schedule (HTS), maintained by the U.S. International Trade Commission. This code determines the duty rate you’ll pay, which can range from 0% to well over 25% depending on the product and its country of origin.
You can look up HTS codes and their associated duty rates at hts.usitc.gov. The schedule is organized into 99 chapters covering everything from live animals to works of art. Finding the correct code for your product matters because misclassification can result in penalties, delays, or unexpected duty bills. If your product doesn’t fit neatly into one category, you can request a binding ruling from CBP that tells you the official classification before you ship.
Beyond standard duty rates, tariff policy can shift. Executive orders and trade agreements periodically add or remove extra duties on goods from specific countries. These changes can significantly affect your landed cost, so build some margin flexibility into your pricing model rather than assuming today’s duty rate will hold indefinitely.
Secure a Customs Bond
CBP requires a customs bond for any commercial shipment valued over $2,500. The bond is a financial guarantee that you’ll pay all duties, taxes, and fees owed on your imports. You have two options.
- Single entry bond: Covers one shipment. The bond amount is generally equal to the total entered value of the goods plus any duties, taxes, and fees. This makes sense if you’re importing infrequently or testing a new product.
- Continuous bond: Covers all your shipments for a 12-month period. The bond amount is set at 10% of the duties, taxes, and fees you paid over the previous 12 months, with a minimum of $50,000 for most importers. If you plan to ship regularly, a continuous bond is more cost-effective and eliminates the need to arrange a new bond for every shipment.
You purchase bonds through a licensed customs surety company, not directly from CBP. The premium you pay is a fraction of the bond’s face value, typically ranging from a few hundred dollars for a single entry bond to $500 or more annually for a continuous bond, depending on your import volume and risk profile. The minimum bond amount for any CBP bond is $100, though in practice most commercial importers will need bonds well above that threshold.
Arrange Shipping and Logistics
Getting goods from an overseas factory to your warehouse involves several moving parts: ocean or air freight, port handling, customs clearance, and domestic delivery. Most new importers work with a freight forwarder, a company that coordinates the entire chain and handles the paperwork on your behalf.
Ocean freight is far cheaper than air for bulky or heavy goods and is the standard choice for most imported consumer products. Transit times from major Asian ports to the U.S. West Coast typically run two to four weeks, with East Coast deliveries taking longer. Air freight cuts transit to days rather than weeks but costs several times more per kilogram, so it’s best reserved for small, high-value, or time-sensitive products.
Shipping costs depend on the volume and weight of your goods, the origin and destination ports, and current market conditions. Freight rates fluctuate with fuel prices, port congestion, and seasonal demand. Get quotes from at least three freight forwarders before your first shipment, and ask them to break out every fee: ocean/air charges, port handling, customs brokerage, documentation, and last-mile delivery to your warehouse.
Many freight forwarders also offer customs brokerage, meaning they’ll file your entry documents with CBP on your behalf. This is worth paying for, especially early on, since mistakes in customs paperwork can lead to shipment holds, fines, or goods sitting in a bonded warehouse racking up storage fees.
Calculate Your Startup Costs
Import businesses are capital-intensive upfront because you’re paying for inventory, shipping, and duties before you make a single sale. Here’s a realistic breakdown of what to budget for:
- Business registration: State LLC or corporation filing fees range from about $35 to $500 depending on your state. An EIN from the IRS is free.
- Product samples: $50 to $500 depending on the product, plus express shipping costs.
- First inventory order: Varies wildly. Many overseas factories have minimum order quantities of 500 to 5,000 units, so even inexpensive products can require $2,000 to $10,000 or more for a first purchase.
- Shipping and freight: Budget $1,000 to $5,000 or more for a first ocean freight shipment, including port charges and domestic delivery.
- Customs bond: A few hundred dollars for a single entry, $500 or more annually for continuous.
- Third-party inspections: $200 to $500 per factory visit.
- Customs duties: Depends entirely on your product’s HTS classification and value. Calculate this before ordering so it doesn’t surprise you.
All told, a modest first import shipment realistically requires $5,000 to $20,000 in upfront capital. You can start smaller by sourcing products with low minimum order quantities or using air freight for a small test batch, but cutting too many corners on quality control or logistics creates problems that cost more to fix later.
Set Up Sales Channels
Your import business needs a way to reach customers. The most common paths are selling on Amazon or other e-commerce marketplaces, building your own online store, or wholesaling to retailers and distributors. Each has different margin structures and operational demands.
Marketplace selling (Amazon, Walmart Marketplace) gives you immediate access to millions of buyers but comes with referral fees, fulfillment costs, and intense price competition. Building your own e-commerce site through Shopify or a similar platform gives you more control over branding and margins but requires you to drive your own traffic through advertising or content marketing. Wholesale relationships offer larger, more predictable orders but at lower per-unit margins, and retail buyers will expect professional packaging, consistent supply, and competitive pricing.
Many successful importers use a combination: selling direct to consumers online for higher margins while also wholesaling to brick-and-mortar stores for volume. Start with one channel, prove the product sells, then expand.
