If you import goods that fall into the following tariff chapters, 82, 84, 85, 86, 87, 88 and 80, and the goods can be classified as new machinery, vehicles, vessels, and/or new complex parts and equipment, and the “large complex componentry” of the item(s) are manufactured after December 1st 2018, have your supplier provide you with a declaration stating that the goods are new, unused and have not been field tested. That way you can avoid having to meet the Brown Marmorated Stink Bug (BMSB) conditions currently in place.
