Section 301 forced labor This HTS appears on the 9903.05.88 exemption list for articles of civil aircraft (U.S. note 52(d)). That exemption depends on the END USE of the goods, which cannot be read from an HTS code, so the duty is charged here. If your entry qualifies, claim 9903.05.88 and this 12.5% does not apply — confirm with your customs broker. 9903.05.31 | 12.5% | $1,250.00 |
Effective duty rate | 37.5% | $3,750.00 |
