The problem

Every FOB quote hides a duty stack you have to guess at

Turning a supplier's FOB quote into a real delivered US price today usually means one of three things, and none of them scale.

A broker on retainer
You pay someone else to hold the classification knowledge, and every new substance is another phone call and another wait.
A spreadsheet someone maintains
Rates copied in by hand, out of date the moment a schedule changes, with no record of where a number came from or who checked it.
Guessing at the stack
Section 301, the 2026 reciprocal tariff layer, and AD/CVD flags can all apply to the same product. Missing one turns a competitive quote into a loss.
How it works

Substance in. DDP price out.

Substance in

Send us whatever you have: the product name, a spec sheet, or the safety data sheet. We resolve it to its CAS number, the single identifier that drives everything downstream.

CAS lookup

HTS classification

The substance is classified against the live USITC Harmonized Tariff Schedule, not a cached copy someone forgot to update.

Live USITC schedule

Ruling citations attached

Where a published CBP ruling exists for the classification, its citation travels with the answer so you can see the primary source, not just a number.

CBP ruling citations, where they exist

Full duty stack

Base rate, Section 301, the 2026 reciprocal tariff layer, and AD/CVD flags are all evaluated together, not bolted on after the fact.

Base rate + Section 301 + reciprocal + AD/CVD

Freight and soft costs

Landed cost inputs beyond duty, freight, and the soft costs that actually show up on the invoice, roll into the same number.

Freight + soft costs

DDP price out

One delivered price, with a confidence tier and its supporting citations attached, ready for your sign off before it reaches a customer.

Delivered price + confidence tier
Confidence, not guesswork

Every classification carries a tier and its citations

A number without provenance is just a guess with more decimal places. Every answer we hand back tells you how earned it is.

A tier on every answer
Each classification carries a confidence tier, so you know how solid the answer is before you build a quote on it.
Citations attached
Where a published CBP ruling or CROSS precedent supports the classification, the citation is there with it, not filed away somewhere else.
A record behind every decision
Thousands of logged classification decisions sit behind the tiers you see today, and that audit trail keeps growing with every product we add.
Sign off workflow

You approve the facts. We do the homework.

Every classification requires your sign off before it is used in a quote. Nothing reaches a customer on our say so alone.

Classification proposed
The substance is classified against the live schedule and the duty stack is assembled around it.
Citations and duty stack attached
Published ruling citations, where they exist, and every duty layer are shown alongside the classification, not buried in a footnote.
Confidence tier shown
You see how earned the answer is before you act on it, every time.
You approve before it ships
Sign off is the gate. Nothing moves from classification to customer quote without it.
Before you file

Read this before you use a classification in a filing

Littoral provides tariff classifications and landed cost estimates for commercial planning only. Littoral is not a law firm or a licensed customs broker, and nothing on this platform is legal advice. Classifications and duty rates are drawn from primary sources, including the current USITC Harmonized Tariff Schedule and published CBP rulings, but final classification authority rests with U.S. Customs and Border Protection. Any entry or official submission to the U.S. Government should be reviewed by a licensed customs broker or trade counsel before filing.

Approve the facts. Send the DDP price.
