What this HTS page tells you
For HTS 3004.31.00, this page shows the official description, its place in the Chapter 30 hierarchy, and the current source-backed context available before you estimate a shipment. Coverage is limited to the current exported snapshot and this code's scope. The estimator below then applies origin, entry date, and shipment facts.
Code meaning, scope, and limits
Chapter context: Medicaments (excluding goods of heading 3002, 3005 or 3006) consisting of mixed or unmixed products for therapeutic or prophylactic uses, put up in measured doses (including those in the form of transdermal administration systems) or in forms or packings for retail sale:.
Coverage boundary: this page defines classification meaning and observed scope only. It is not legal advice and does not substitute for invoice-level import classification review.
Official source context: the USITC HTS schedule and linked measure entries are the canonical basis for this output. If a result is missing or marked for review, the calculator needs additional context that cannot be inferred from this code alone.
This is not a final exact classification. 3004.31.00 has 2 active child lines. Select the child line that matches the goods before relying on a rate or amount.

Origin matters
Rate by country of origin
Same selected child or exact HTS and declared value. Base duty and additional measures are evaluated through the shared calculator core; unsupported or incomplete contexts withhold definitive rates and totals.

Sources and details
Loading country comparison from the current tariff artifact…
Country comparison shows customs duty on declared goods value: base duty plus represented additional measures. “Default” retains a country measure because a possible conditional exclusion requires entry facts that have not been proven; it is not a final eligibility determination. MPF, HMF, freight, and insurance remain in the shipment stack above and are not added to this table. A qualifying preference is never inferred unless the scenario is expressly selected and supported for that origin.

The current HTS citation is always shown. USTR, CBP, Federal Register, and trade-program citations appear only after the shared engine returns them for the selected child, origin, date, value, and entry assumptions.

Questions about 3004.31.00
FAQ for this HTS code.
Is HTS 3004.31.00 an exact classification?
No. It is a 8-digit tariff line with 2 active child lines in the current hierarchy. Select the child description matching the goods before calculating.
What is the current base duty?
A category-level amount is intentionally withheld. Its child lines can have their own rate-resolution records; choose one in the shipment control.
Why does country of origin change the rate?
Origin determines the applicable tariff column, country-specific additional measures, and supported trade-program treatment. The comparison above runs every displayed country through the same engine; when the engine cannot prove a numeric result, the row says manual review instead of zero.
How is total duty calculated for this HTS code?
First choose the applicable active child line; HTS 3004.31.00 is not itself treated as an exact calculable line. The shared engine resolves the applicable base or Column 2 rate, supported preference treatment, and additional measures, then calculates MPF and HMF separately when the selected entry assumptions support them. Freight and insurance stay outside the declared customs-value assumption and are added only to landed cost. Any unresolved component causes the final total to be withheld for manual review.
