Pre-filing checks
Catch filing errors before CBP does
Every ISF and entry draft is checked against the rules before you can submit it. Ask for an AI review when a draft looks off. And if CBP still rejects it, the error comes back in plain English with the steps to fix it.
Bring your last rejection and we'll walk through it.
Every draft
Rule checks run on every draft, every time
Before a filing can go to CBP, it passes a fixed set of checks, on ISF and entry drafts alike. They're the same whether you submit from the app, in bulk, or through the API.
- HTS code must be 6 to 10 digits in a valid chapter
- Country codes must be valid two-letter ISO codes
- SCAC must be exactly four letters
- Arrival date must be after departure
- Importer of record number required
- ISF-5 needs the booking party
- Deadline under 24 hours away, or already passed
Critical errors block the submit. Warnings tell you what to look at.

A second read of the draft before it goes
On any draft, ask the AI to review it. It reads the filing and points out what looks inconsistent: a description that doesn't match the HTS chapter, a party that looks incomplete. It runs only when you ask, and your team makes the call.
We send only the filing being reviewed.
If CBP says no
Rejections come back in plain English
CBP answers with codes. MyCargoLens translates the code into what went wrong and numbered steps to fix it, right on the filing. Fix it, resubmit, and you're never charged twice for the same shipment.
When three or more recent rejections share one cause, the inbox shows it once with every affected filing, so you fix the template, not twenty filings.
Risk flags
Duty and agency flags while you're still drafting
The rules keep moving. Section 301 duties now cover 60 economies from July 24, 2026. MyCargoLens flags what you'd want to know before you file:
- HTS codes that may fall under an ADD/CVD order, from orders pulled from the Federal Register daily.
- Possible UFLPA exposure, from origin details on the parties and high-risk HTS chapters.
- Agencies that may own the code: FDA, USDA-APHIS, EPA, FCC and others.
We flag and explain. You or your broker decide.

Questions about the checks
Not if it has a critical error. Warnings don't block you; they tell you what to look at.
Yes. Every submit path runs the same checks first.
No. It runs only when someone on your team asks for it.
It sees only the filing it's reviewing.
No. You're charged when CBP accepts the shipment, and resubmits and amendments are never charged twice.
No. It catches the errors the rules and the review can see, and explains the rest when CBP answers.
No. MyCargoLens is software, not a customs broker. It gives your team or broker a cleaner draft and a clearer answer.
