- Confirm with your customs broker how a potential future limited exclusion order or cease and desist order might relate to your goods.
- Check the ITC docket for updates on the scope of the investigation and any respondents named.
- Confirm the classification and sourcing of any rosin-ester products you import so you can track relevance as the case develops.
