Import Tips & Compliance

• Submit OEM compatibility data showing linkage to specific boiler models for accurate HTS verification

• Label as 'soot blower lances for steam boilers' to prevent reclassification as generic cleaning equipment

• Check for Section 232 tariffs on steel content; segregate US-origin components if applicable
