- 8544.42.10
- 8544.42.20
- 8544.42.90
- 8544.49.10
Ask your broker to compare these with your shipment’s classification. The presence of copper alone does not put a product in scope.
- Ask the supplier for the copper details. The filing requires the primary country of smelt and the country of cast. Secondary smelt country reporting is optional.
- Send the information to the broker. Have the importer and broker check that the required declaration is included in the entry summary, the customs record used to report the imported goods and duties.
- Flag anything unknown. CBP allows “OTH” (other) when a country is unknown. Ask the broker how to report that; do not guess or leave the required declaration out.
Who should follow up?
For buyers, the useful first contact is the broker handling the US entry. Ask whether your goods are covered and what information is still missing. If the seller arranges clearance, ask it to coordinate this check with the importer and broker.
The importer must provide the required information. Your supplier may need to obtain it from its own supply chain, so raise the question before the filing is due.
If the supplier cannot identify the country
An unknown country and an omitted declaration are different filing situations. CBP expressly permits “OTH” for unknown countries. The September 14 change concerns rejection when the required reporting is missing; it does not announce a new tariff or a ban on all goods containing copper.
Read the July reporting guidance with your broker for the filing details. This article does not classify your product or calculate its duties.
