Customs, duties, and importing: the basics every buyer should know

How tariff classification works

Every product imported into the United States has to be classified under the Harmonized Tariff Schedule (HTS), a detailed system of codes that assigns each kind of good a category. Classification is the foundation of importing, because the HTS code determines the duty rate, drives other requirements, and is what the government uses to know what you are bringing in. The system is more intricate than it looks, since seemingly similar products can fall under different codes with different treatment, and the correct code depends on the precise nature, material, and use of the item. Getting the classification right is genuinely important and not always obvious.

Because classification drives duty and compliance, it is not a place to guess. The HTS is published and can be consulted, but applying it correctly to a specific product often takes expertise, which is one reason importers rely on customs brokers. An incorrect classification can mean paying the wrong duty, facing penalties, or having goods held. For any real import, confirm the correct HTS classification for your specific product, ideally with a licensed customs broker, rather than assuming a code from a similar item. Treat anything in this guide as orientation, not a classification ruling for your goods.

Duties and tariffs, in plain terms

A duty, or tariff, is a tax on imported goods, and the rate is tied to the product's HTS classification and its country of origin. Some goods carry low or no duty; others carry significant rates, and certain products or origins are subject to additional or special tariffs layered on top of the standard rate. The duty is calculated on the customs value of the goods, so the amount you owe depends on both the rate and the declared value. This is a real cost of importing that has to be built into landed cost, and it is one buyers most often underestimate when comparing a low overseas unit price to a domestic one.

Crucially, duty rates are not fixed background facts; they vary by product and origin and they change with trade policy, so a rate that was true at one time may not be current. For that reason this guide deliberately does not state specific duty percentages, because any number here could be wrong by the time you read it or wrong for your exact product. The correct rate for your goods must be confirmed against the current HTS and CBP guidance, ideally through a licensed customs broker. Build the verified duty into your cost before you commit, not after, since it can change whether a direct import actually beats buying domestically.

What a customs broker does

A licensed customs broker is a professional authorized to handle the customs clearance of imported goods on an importer's behalf, and for most importers they are close to essential. Brokers help classify goods under the HTS, prepare and file the entry paperwork with Customs and Border Protection, calculate and arrange payment of duties and fees, and navigate the other agencies and requirements that can apply to specific products. Their value is that they do this for a living and stay current on rules that change often, which is exactly the knowledge a small or new importer lacks. Using one does not remove the importer's legal responsibility, but it sharply reduces the chance of costly errors.

For a buyer deciding whether to import direct, the broker is part of the real cost and part of the answer to whether direct import makes sense. Their fees add to landed cost, but they also make direct importing feasible without becoming a customs expert yourself. One of the quiet advantages of buying from a domestic importer or distributor instead is that they have already done all of this, so you inherit cleared, duty-paid goods without engaging a broker at all. If you do import direct, engaging a licensed customs broker early is one of the most sensible moves you can make, and this guide assumes you will verify your specifics with one.

The entry process at a high level

Bringing goods into the country involves a customs entry: a formal process by which imported goods are declared, classified, valued, and released by Customs and Border Protection after any duties and fees are handled. At a high level, the goods arrive, an entry is filed (usually by your broker) declaring what they are and their value, CBP reviews it and may examine the goods, duties and fees are paid, and the shipment is released for delivery. There are documentation requirements and timelines, and goods can be held or examined, which is part of why lead time on imports is unpredictable. This is a simplified sketch; the real process has more moving parts.

The practical implications for a buyer are about time, cost, and responsibility. Clearance adds time to your lead time and can vary, so it has to be built into seasonal planning especially. It adds cost through duties, fees, and broker charges. And it carries responsibility: the importer of record is legally accountable for an accurate, compliant entry, which is another reason to lean on a broker and to keep good records. As with everything in this guide, treat this as orientation and confirm the current entry requirements for your specific goods with CBP and a licensed customs broker rather than relying on a general description.

Country-of-origin marking

Imported goods generally must be marked with their country of origin so the ultimate purchaser can see where the product was made, and the rules about how, where, and how permanently that marking appears are specific. Country of origin also matters beyond the label: it feeds into the duty rate, since tariffs can depend on origin, and into whether special or additional tariffs apply. So origin is both a labeling obligation and a cost-and-compliance factor, and getting it wrong can mean goods are refused, held, or re-marked, or that you miscalculate duty.

For a buyer, the practical points are to confirm that goods are correctly and durably marked as required before they ship, to understand that origin affects your duty, and to be cautious of any supplier vague or evasive about where goods are actually made. Marking requirements vary by product and can be detailed, so verify the current rules for your specific goods rather than assuming a generic sticker suffices. When buying from a domestic importer, this has usually been handled, but the responsibility to sell properly marked goods still ultimately matters, so it is worth confirming rather than assuming.

Product safety and compliance

Customs clearance is not the only government hurdle; many consumer goods must also meet product-safety and regulatory requirements, and this is especially true for the toys and novelties at the heart of this site's subject matter. Children's products fall under the Consumer Product Safety Commission and standards such as ASTM F963, with rules on small parts and choking hazards, certain chemicals like lead, warning and tracking labels, and often third-party testing and a children's product certificate. Other goods can have their own labeling or content requirements. These obligations exist independently of duty and can determine whether goods may legally be sold at all, so they cannot be treated as an afterthought.

The responsible approach is to confirm, before importing or reselling, that the specific product meets the applicable safety and labeling rules, that required testing and certificates exist, and who is responsible for compliance. For imported children's products in particular, do not rely on a supplier's verbal assurance; verify against current CPSC and ASTM F963 requirements and consult someone qualified when in doubt. Buying from a reputable domestic importer can shift much of this burden, since they have presumably handled it, but it does not erase a reseller's own responsibility. Compliance and customs together are why importing is more than just finding a cheap price, and why this guide keeps pointing you to official sources and licensed professionals.
