Current-source rule

Applicable U.S. duty exposure depends on classification, origin, entry date and active trade measures. At the 20 August 2026 source review, SAXUM observed USITC 2026 HTS Revision 16, published 14 August 2026, as the latest reviewed HTS revision. SAXUM does not publish a static “all-in rate”; each review is dated against the current HTSUS, CBP guidance and the customer’s customs-professional decisions, and a newer official authority candidate must be staged and approved before authoritative calculation claims use it.

The operational problem

Why the standard portal or checklist is not enough

A base HTS duty rate can be only one layer of the cost. Additional duties, exclusions, origin facts and product-specific measures can change the amount owed. A simple calculator can create false confidence when its assumptions are incomplete.

Truth boundary: Saxum controls preparation, evidence and technical review. It does not replace the customer’s legal, tax, accounting, scientific or regulatory professionals, and it does not control external acceptance.

Best-fit customer

Customs advisers, importers and ecommerce operators with repeat SKU exposure

Problems this product helps control

Import lines where HTS classification, country of origin, Section 301 or other special duties and landed-cost assumptions need a line-level tariff exposure review.

What Saxum needs

A bounded intake, not an open-ended data dump

The case starts with enough context to reproduce the problem and define responsibility. Credentials, unrelated personal data and unsupported assumptions are excluded.

  • SKU and product descriptions
  • Current HTS classifications, if known
  • Country of origin and supplier facts
  • Entry values, quantities and recent broker documentation
The deliverable

What arrives at the end of the engagement

The output is designed to be reviewed, handed off and defended—not merely marked “passed.”

  • Line-level duty-stack worksheet
  • Assumption and uncertainty register
  • Change-sensitive SKU watchlist
  • Potential refund or correction candidates
  • Questions for the customs broker
  • Executive landed-cost summary
Controlled workflow

From messy source material to a reviewable release packet

Each stage has a clear stop condition. When evidence is insufficient, the case pauses rather than manufacturing certainty.

Ingest

Normalize the commercial and classification inputs without silently inventing missing facts.

Model

Apply the declared tariff layers and surface every material assumption.

Challenge

Identify classification, origin and remedy questions requiring professional confirmation.

Handoff

Deliver a broker-ready workbook and prioritized action register.

Tariff Change Radar

Turn each official revision into a SKU-level action list

The platform freezes the loaded HTS and remedy sources, calculates supported duty stacks, compares scenarios and routes unsupported classifications or legal conclusions to a qualified customs professional.

What changed

Hash and monitor official sources, preserve readable change evidence and pause recurring cases when a material source revision requires rule review.

Portfolio impact

Identify affected SKUs, origins, entered values and margin scenarios instead of sending a generic tariff bulletin to the business.

Decision control

Assign exceptions, attach broker evidence, require Human ReviewPass approval and publish a signed executive summary with exposure and time-value metrics.

Adviser portfolio mode

Monitor tariff exposure across multiple importer portfolios

Keep importer/SKU populations segregated while reusing approved authority sources, scenario logic and revision monitoring across the advisory team.

Segregated accounts

Each customer, entity or operating unit keeps separate source evidence, mappings, exceptions and outputs.

Reusable controls

Approved mappings and review policy reduce repeat setup without allowing one client's assumptions to leak into another.

Portfolio oversight

Firm teams can see recurring due work, unresolved exceptions and evidence-backed outcomes without flattening client boundaries.

First-cycle outcome proof

Show the buyer exactly what Saxum proved

The first controlled cycle produces customer-visible proof before the workflow is expanded. Saxum keeps internal completion separate from external/provider acceptance and never turns estimates into verified outcomes.

Source coverage

See which files, mappings and authority sources were used, what was missing and which assumptions remained unresolved.

Exception register

Every blocker has a reason, owner and current state. Unsupported facts remain open instead of disappearing into a generic pass.

Evidence-graded scorecard

Separate Saxum-completed work from provider-final evidence, verified value, source-backed exposure, observed time savings and estimates.

Commercial fit

Use this when the cost of an unresolved exception exceeds the cost of review

Saxum is strongest when the workflow repeats, the evidence is fragmented and one preventable mistake can delay revenue, create rework or weaken the customer’s audit trail.
