Price: 5 USD
Author: TariffCheck

Calculate import duties, Section 301 tariffs, and total landed cost in seconds

TariffCheck at tariffcheck.co estimates a likely HTS classification, duties, surcharges, and landed cost from the product details you provide. It is not affiliated with tariff-check.com and is not a customs broker, a binding customs ruling, or legal advice. Verify classifications and current rates before filing an entry.

Built on published US trade sources

TariffCheck references published USITC, CBP, USTR, and Federal Register material. Its output is a planning estimate, not a binding classification or customs entry decision.

How the calculation works

Classify the product into a 10-digit HTS code using an AI classifier trained on CROSS rulings plus the product description.
Identify country of origin and select the applicable tariff column (Column 1 General for WTO members, Column 2 for non-NTR, free-trade preferences for FTA eligibles).
Layer on active surcharges: Section 301 (China Lists 1–4A), Section 232 (steel/aluminum), Section 122 (reciprocal), and IEEPA actions (Russia/Belarus/Iran/Cuba/Venezuela) where they apply.
Check trade-agreement preferences — USMCA, KORUS, CAFTA-DR, Israel FTA, etc. — and apply the preferential rate only when rules of origin are satisfied.
Sum the final rate, apply it to the declared customs value, and output the estimated duty + total landed cost.

Drug import tariff answers

These quick answers map to the most common pharmaceutical tariff questions: how to calculate duty, where HTS Chapter 30 applies, and when a drug tariff calculator still needs product-specific review.

How to calculate import tariff for prescription drugs

Start with the 10-digit HTS classification, confirm country of origin, check whether the drug is a finished dose form or an API, then layer the base duty with any active trade actions. The final estimate is duty rate multiplied by declared customs value, plus any applicable user fees.

US HTS codes for pharmaceutical imports

Many pharmaceutical products sit in HTS Chapter 30, but APIs, excipients, devices, and combination kits can classify elsewhere. TariffCheck uses product wording plus official HTS data to narrow the likely chapter before estimating the rate.

What a drug tariff calculator can and cannot decide

A calculator can estimate duty from HTS, origin, and value. It cannot replace binding CBP classification, FDA import review, or anti-dumping checks for a specific manufacturer.

Pharmaceutical import	Common HTS starting point	Classification note
Finished retail medicines	3004	Common bucket for medicaments in measured doses or retail packing.
Unpackaged medicaments	3003	Mixtures of two or more constituents not packed for retail sale.
Vaccines, antisera, blood products	3002	Often requires FDA and CBP documentation beyond the tariff rate.
Active pharmaceutical ingredients	Usually Ch. 29 or Ch. 30	Some qualifying APIs may fall under pharmaceutical duty-elimination lists.

Common Problems TariffCheck Solves

Each solution is AI-generated based on proven methods. Describe your problem and get a personalized result in seconds.

Importers need to estimate landed cost before placing orders

Solution: Instant tariff breakdown with HTS code identification

Enter a product description and TariffCheck identifies the likely HTS code, calculates base duty, Section 301 and Section 122 surcharges, and estimates total landed cost — all in under 10 seconds.

Ecommerce sellers sourcing from China face unpredictable tariff costs

Solution: 2026 Section 301 tariff rates included automatically

TariffCheck includes all current Section 301 tariff lists (Lists 1-4B) with 2026 rates, so ecommerce sellers can accurately price products sourced from China without manually searching HTS codes.

Small businesses cannot afford customs brokers for cost estimation

Solution: Free preliminary estimate before professional review

Use TariffCheck for early feasibility planning, then confirm the classification and filing treatment with a licensed customs professional when needed.

New importers do not understand HTS codes or tariff schedules

Solution: AI identifies HTS codes from plain English product descriptions

Instead of searching through 18,927 HTS codes manually, describe your product in plain English (e.g., 'stainless steel water bottle') and TariffCheck identifies the correct classification.

Worked examples

Real scenarios run through the same engine you’ll use. Each output is traceable to a specific classification, policy action, or trade-agreement rule.

Vietnamese steel rebar — Section 232 applies

Input

Product:: Steel rebar, 10 mm diameter
Origin:: Vietnam
Customs value:: $10,000

Output

~$3,020 duty (30.2%)

Stacked MFN + Section 232 surcharge

Why

5% MFN Column 1 General rate + 25% Section 232 steel surcharge applies across WTO-member origins. Vietnam is not party to any US FTA for steel, so no preference. Watch for anti-dumping / countervailing duty orders on specific producers — those can stack further and are not included in this baseline estimate.

HTS: 7213.10.00

Chinese passenger EV — Section 301 stack to 100%

Input

Product:: Battery-electric passenger vehicle
Origin:: China
Customs value:: $30,000

Output

~$30,750 duty (102.5%)

MFN + Section 301 (Biden 2024 increase)

Why

2.5% MFN baseline + 100% Section 301 List 4A rate after the Biden 2024 EV tariff hike. IEEPA or Section 232 auto-proclamation may add further depending on effective date. This is one of the scenarios where duty exceeds unit value — the Lith-ion battery sub-components often trigger an additional 25% layer that is classified separately.

HTS: 8703.80.00

Mexican cotton t-shirt under USMCA — 0% preference

Input

Product:: Men's cotton knit t-shirt
Origin:: Mexico
Customs value:: $1,000
USMCA cert:: Yes (yarn-forward verified)

Output

$0 duty (USMCA preference)

Would be 16.5% MFN without cert

Why

MFN on knit cotton shirts is 16.5%. USMCA Chapter 4 rule of origin requires yarn-forward for Chapter 61 — yarn must be spun in a USMCA country, fabric knitted there, and the garment cut-and-sewn there. With a valid certification of origin, the preferential rate is 0%. Fail any step and the MFN rate applies.

HTS: 6109.10.00

Indian atorvastatin API — pharma zero-for-zero

Input

Product:: Atorvastatin calcium API
Origin:: India
Customs value:: $50,000

Output

$0 duty (Pharma Ex-List)

GATT pharmaceutical elimination

Why

Atorvastatin is on the Pharmaceutical Products Agreement (PPA) elimination list, an annex to the GATT that zeroes out most pharmaceutical active ingredients across WTO members. Verify the specific CAS number on the USITC ex-list — not every API qualifies, and finished dose forms often do not.

HTS: 2933.99.90 (CAS 134523-03-8)

German spark plugs — standard MFN

Input

Product:: Automotive spark plug, ceramic insulator
Origin:: Germany
Customs value:: $5,000

Output

$125 duty (2.5% MFN)

No surcharges apply

Why

Standard Column 1 General MFN rate for WTO-member origins. Germany is not subject to Section 232 auto-parts surcharges on this sub-code as of 2026 Q2. No anti-dumping order on German spark plugs. A clean, rate-table lookup — but the HTS sub-code matters: 8511.20 (magnetos) sits at a different rate.

HTS: 8511.10.00

What Makes TariffCheck Different

Unlike the official USITC HTS search that requires you to already know your classification code, TariffCheck uses AI to identify the right HTS code from a plain English product description and calculates all applicable tariffs automatically.

vs.	Why TariffCheck Wins
USITC HTS Search	USITC requires you to know your HTS code; TariffCheck identifies it from product descriptions
Customs Broker Consultation	TariffCheck provides preliminary estimates; a licensed broker can make case-specific filing and compliance judgments
Manual HTS Lookup	TariffCheck narrows a likely classification from a product description; manual source review remains necessary for ambiguous products

Frequently Asked Questions

How does TariffCheck work?

TariffCheck uses AI to analyze your product description and identify the most likely HTS (Harmonized Tariff Schedule) code. It then calculates the base duty rate, adds any Section 301 tariffs (for Chinese goods) and Section 122 surcharges, estimates shipping costs, and produces a total landed cost breakdown in seconds.

Is it free to try?

You get 3 free tariff calculations on signup with no credit card required. After that, purchase 50 credits for $5 (one-time). Each credit generates one full tariff breakdown.

How accurate is the tariff estimate?

TariffCheck does not publish an audited accuracy percentage. Results are preliminary estimates based on the details entered and the cited source material. Classification, origin, exclusions, trade remedies, and effective dates can change the amount, so verify the result before filing.

What countries are supported?

TariffCheck supports imports from any country into the United States. Section 301 tariffs are automatically applied for products from China. Most Favored Nation (MFN) rates are used for other countries unless a free trade agreement applies.

What are Section 301 tariffs?

Section 301 tariffs are additional duties imposed on Chinese goods as part of the US-China trade dispute. In 2026, these range from 7.5% to 100% depending on the product category, on top of the regular duty rate.

What are Section 122 surcharges?

Section 122 surcharges are tariff surcharges applied to imports from specific countries. In 2026, these affect imports from several countries and are calculated on top of regular duties.

How long do credits last?

Credits never expire. Once purchased, your 50 credits are available until used. No monthly fees or subscriptions.

Is my data safe?

We do not store your product descriptions or calculation results after your session ends. See our Privacy Policy for details.

What makes TariffCheck different from hiring a customs broker?

TariffCheck provides a quick preliminary estimate and source trail. A licensed customs broker can review documentation, make case-specific judgments, and handle entry filing. The calculator is not a replacement for those professional services.

Is TariffCheck legal advice, customs advice, or a brokerage service?

No. TariffCheck is an independent estimation tool for preliminary planning. It does not provide legal advice, a binding HTS classification, customs brokerage, or a guarantee of duties owed.

What is the official TariffCheck website?

The official website for this calculator is https://tariffcheck.co. TariffCheck is not affiliated with tariff-check.com or other similarly named tariff and customs services.
