From the trade desk

The rules keep moving. The firm writes as they do.

No. 01

Tariffs and classification

When duty rates move, the right customs classification is real money for an importer.

No. 02

Export controls

Technology, software, and dual use goods need clearance before they ever leave the country.

No. 03

Small parcel imports

De minimis rules for direct to consumer shipments keep changing, and the costs land fast.

Questions

Before you call.

Where is TEIL Firms located, and where can it handle matters?

The office is at High Point Towers in Hillside, Illinois, just west of Chicago. The firm is admitted in Illinois, New Jersey, and before the U.S. Court of International Trade, and has handled matters for clients trading on six continents.

What does a first conversation look like?

It starts with a free 15 minute intake by phone. If the matter fits the practice, the next step is a scheduled consultation. Bring whatever paper you have: contracts, registrations, or shipment documents.

What kinds of businesses does the firm represent?

Small and midsize companies that import, export, or sell internationally, with depth in manufacturing, technology, food, and transportation. If your goods or deals cross a border, the practice fits.

Can the firm work in languages other than English?

Yes. Across the team the firm works in English, Spanish, French, and Arabic, which matters when contracts, counterparties, and regulators do not all speak the same language.

What is the U.S. Court of International Trade?

It is the federal court that hears customs and international trade disputes, sitting in New York. Admission to practice before it means the firm can take a trade matter from the agency level into court without handing it off.
