AI can propose candidate HS codes and summarize duty estimates, but the final lookup should be treated as an assistive tool with citations, not a legal customs ruling.

04 Business breakdown

Who needs this

Small US-based e-commerce importer or online seller who buys products from China and needs to estimate landed cost before placing a purchase order.

Job to be done

When evaluating a new product to source, I need a reliable HS code and import duty estimate before ordering, so I do not get surprised by customs charges.

Why they might pay

One avoided misclassification or surprise duty can outweigh the subscription cost. It also saves time spent searching official tariff databases or waiting on broker quotes.

Alternatives

Free official HTS/tariff search tools,Customs broker or freight forwarder,Supplier's DDP quote,Spreadsheets and personal knowledge,Other free tariff lookup websites

Differentiation wedge

A concierge lookup: user submits a product description, receives HS code candidates and duty rate for one country pair, with links to official sources.

OPC scope

Landing page + manual lookup service for one country pair and one product niche; no full tariff database or automation

Open questions

  • Which product vertical has the strongest recurring pain?
  • Do users trust AI-suggested HS codes enough to pay?
  • Which country pair creates the most acute comparison need?
  • What is the best pricing trigger: per lookup, monthly subscription, or annual volume?

05 Search & acquisition

Primary channel:

SEO for long-tail product + origin queries; niche communities such as Reddit import/ecommerce subreddits, ecommerce Facebook groups, and a Hacker News 'Show HN' post.

Talking points

  • Stop guessing HS codes by hand
  • See the duty rate before you buy inventory
  • Every lookup includes official source links

Minimum experiment 06 Minimum validation experiment

One falsifiable step before you continue or stop.

Valid signal = real task completion, reuse, or pay intent — with observe + continue/stop.

Pick one niche: US e-commerce importers buying a specific product category from China. List 15 potential users from communities, forums, or existing contacts.

Observe

Whether the candidate has a concrete recent example of looking up an HS code or receiving a surprise duty charge.

Continue

At least 5 people match the niche and describe a current workaround.

Stop

Only hobbyists respond or no one can recall a concrete recent lookup event.

Publish a minimal landing page: 'Get HS code + US import duty estimate for your product in 24 hours — free during test.' Ask for product description and email.

Observe

Number of real product submissions and whether they come from the target importer segment.

Continue

At least 5 submissions arrive from target users after simple outreach.

Stop

Submissions are off-target, bot-like, or zero after outreach.

For each submission, manually find candidate HS codes and duty rates using official government tariff sources. Reply with a short source-linked answer.

Observe

Response rate, follow-up questions, and whether the user submits a second product.

Continue

At least 2 users submit a second product and ask about price or accuracy.

Stop

No one responds, or all users say their broker/free source was already good enough.

Follow up with each participant: ask what they do today, what a misclassification would cost, and whether they would pay for a faster lookup.

Observe

Stated willingness to pay and description of existing alternatives.

Continue

At least 2 participants state a specific price or current cost of the problem.

Stop

Participants only say 'nice to have' and cannot name any money or time cost.

Model hypothesis

  • People who import products may repeatedly need HS code lookup and duty comparison before quoting landed costs.
  • Smaller importers without a full-time customs broker may be more likely to feel this pain.
  • A source-linked answer may be more trusted than a generic AI guess.

Known facts

  • The user provided the keyword 'TariffPedia – HS code lookup and import duty comparison' as a raw idea from a Hacker News context.
  • No interviews, usage data, or payment evidence were provided in this run.
  • HS codes are part of international customs classification, and import duty rates generally vary by product code and country of origin.

Unverified assumptions

  • The first viable user may be a small US e-commerce importer buying from China.
  • A concierge test is the fastest way to generate falsifiable evidence before building a full product.
  • Official source links and a manual verification loop will be needed to establish trust.

AI inference: AI can propose candidate HS codes and summarize duty estimates, but the final lookup should be treated as an assistive tool with citations, not a legal customs ruling.
