Tariff
watch.

CloudPorts™ tracks active U.S. tariff actions — Section 301, Section 232, antidumping and countervailing duty orders, and general rate changes — and turns them into a working estimate of landed-cost exposure before a shipment moves. Model the duty impact below, then request a CloudPorts review for shipment-specific guidance.

Tariff exposure calculator.

Enter a shipment profile and the duty layers that apply to it. CloudPorts calculates the combined rate, the estimated duty owed, and a review flag based on how layered the exposure is. This is a planning estimate only — not a final customs entry determination. Final classification, valuation, and duty liability are determined at entry by U.S. Customs and Border Protection.

Duty & Tariff Layers (%)
Estimated Duty: Effective Duty Rate: Review Flag: Enter duty layers and calculate to see a review flag. Estimate combines the layers entered above against the declared shipment value. It does not account for duty drawback, exclusions, first-sale valuation, or de minimis treatment.

Tariff updates.

The trade-policy layers below are the ones most likely to change a shipment's landed cost without warning. CloudPorts monitors all four against active client shipment profiles and flags exposure before it reaches an invoice.

Section 301 — China Tariff Actions

Additional duties tied to USTR Section 301 product lists.

Section 301 actions apply added duty rates on top of normal customs duty for goods of Chinese origin tied to specific HTS subheadings and exclusion windows. CloudPorts tracks list changes, exclusions, and extensions relevant to client shipment profiles.

  • List coverage and rate changes by HTS subheading
  • Exclusion grants, extensions, and expirations
  • Country-of-origin and substantial transformation considerations

Section 232 — Steel, Aluminum & Derivatives

National-security tariffs on metals and downstream products.

Section 232 measures apply added duty to steel, aluminum, and an expanding list of derivative products regardless of country of origin, with limited exclusion processes. CloudPorts flags shipments where a product's classification falls inside current 232 scope.

  • Metal content and derivative-product scope changes
  • Country-specific quota or exemption arrangements
  • Exclusion request status where applicable

Antidumping & Countervailing Duty Orders

Case-specific duty rates that can be substantial and producer-dependent.

AD/CVD orders apply to specific products from specific countries — and specific producers within those countries — at rates that vary widely and can exceed the value of the goods. These require case-by-case review against active Commerce Department orders.

  • Active order and scope-ruling monitoring
  • Producer/exporter-specific rate identification
  • New investigation and petition tracking

General Rate & Trade Program Changes

Baseline duty schedule and preference-program updates.

Beyond the active trade-action layers, standard HTSUS duty rates, free trade agreement eligibility, and preference programs shift periodically. CloudPorts keeps shipment profiles aligned to the current schedule.

  • HTSUS annual revisions
  • Free trade agreement and preference-program eligibility
  • General Rate of Duty column changes
