The chain: product, heading, rate
Import duty is a rate applied to the customs value of a shipment, and the rate depends on how the goods are classified. Footwear classification lives in chapter 64 of the Harmonized Tariff Schedule, and within that chapter the heading follows mainly the material of the upper and the outer sole. That is the whole logic of this note: a duty rate is not a property of "sneakers" as a category - it is a property of a specific shoe, classified by what it is made of, confirmed by a licensed broker, at the rate in force that month.
Which means the bill of materials is a customs document in disguise. The spec sheet that says what the upper, lining and outer sole are made of is the same document your broker reads to classify the shipment. Get it right once and everything downstream agrees; get it wrong and you pay for it twice, once in reclassification and once in relabeled stock.
| Heading | Covers, in plain words | Why your spec sheet matters |
|---|---|---|
| HTS 6402 | Footwear with rubber or plastic uppers and outer soles | A foam or PU-heavy build can point here; composition must be stated truly |
| HTS 6403 | Footwear with leather uppers | Split leather and full-grain uppers sit here; the leather content must be real and documented |
| HTS 6404 | Footwear with textile uppers | Mesh and knit uppers usually point here; a knit count is a customs fact, not a marketing line |
Those three headings carry most casual sneaker programs. Which one applies to your shoe is a classification question, and classification is a customs broker question - the desk does not classify, does not quote rates, and does not guess. What it does is make sure the description your broker works from is accurate.
Where classification actually gets decided
Your broker reads the spec sheet, the commercial invoice and the packing list together, classifies each model, and confirms the heading and the rate in force - including any additional measures that apply this month, which change more often than most buyers expect. This is why the desk refuses to quote duty figures: a rate repeated from memory is wrong the month the tariff schedule moves, and the importer pays the difference. The working split is simple. The desk supplies accurate product data in writing; the broker classifies and confirms the current rate; the importer books the number into the program's cost sheet. General information only - your licensed customs broker confirms what applies to your shipment.
Stock versus OEM, from a paperwork angle
On the stock route, the list spans categories - cushioned runners, court-inspired lows, leather casuals, chunky builds, sandals - so a mixed carton can span more than one heading. That is not a problem, but it is a structure question: ask your broker how they want the declaration organized, and the desk will supply the per-model composition behind it, model by model, from the list. Mixed-model cartons stay possible; they just get declared correctly.
On the OEM route, the spec sheet fixes materials before sampling, so classification is stable across the program. This is also why material changes mid-program are never just a cost change: swapping a textile upper for a leather one can move the shoe to a different heading, which moves the duty math your broker quoted against. Material decisions belong at the spec stage, where the broker can see them, not at the production stage, where they arrive as surprises. The spec sheet template shows where composition lives in the documents.
A walkthrough without numbers
An example shows the split of roles. A buyer in the US plans a run of a low casual with a split leather upper and a rubber outsole. The spec sheet names the upper, lining and sock, and outer sole materials - written by the desk from the bill of materials, confirmed against the sample. The desk assembles the commercial invoice draft and the packing list on the agreed 12-pairs-per-carton plan, with origin facts and carton marking. The buyer's broker reads those documents, classifies the model under the leather-uppers heading, and confirms the rate in force that month, in writing. The buyer books the landed cost on that figure. Six months later a reorder changes nothing - same spec, same classification - until someone proposes swapping the upper to knit to reach a price point, at which point the change goes back to the broker before it goes to the factory, because the shoe the broker classified would no longer exist.
Customs value is a further broker topic - the declared value of a shipment can involve freight and insurance terms, and the broker confirms what your invoice terms imply. The desk's contribution stays what it was: documents that say exactly what the product is, so every figure downstream stands on something.
Keeping the documents consistent
- Confirm the bill of materials. Upper, lining and sock, outer sole - named exactly, from the program documents.
- Send the broker the set. Spec sheet, draft commercial invoice, packing list - the same files, not summaries.
- Broker classifies and confirms. Heading and current rate per model, in writing from the broker.
- Use one vocabulary everywhere. The composition wording on the invoice matches the spec sheet matches the label.
- Freeze material changes. Anything that alters composition goes back through the broker before production.
Consistency is what keeps shipments boring. Examinations are usually triggered by documents that disagree with each other - a leather word on the invoice that the spec sheet calls PU, a textile count that changed after sampling. Boring paperwork is compliance done at its least expensive, and it is the version that clears exams without stories.
What the desk provides in writing
For any program, on request: per-model material composition, construction type (cemented or vulcanized), origin facts, carton marking, and packing details including the standard 12 pairs per carton. Those are the inputs a broker needs, delivered in the form a broker needs. For how the two routes compare on clock and commitment, read MOQ and lead time, and for the category's material vocabulary, see sneaker materials. If you are building a cost sheet for a US program, send the request form with your channel and destination, and the desk will assemble the product data your broker classifies from - and see shipping shoes to the US for how the cartons themselves are prepared.
