Germany and Japan dominate US imports of parts and accessories for spinning, doubling, twisting, winding, and reeling machinery — the core yarn-production equipment of heading 8445. The US schedule subdivides this subheading into parts of spinning, doubling, or twisting machines (8448391000), parts of winding or reeling machines (8448395000), and remaining parts and accessories of heading 8445 machinery (8448399000). China is also a notable supplier, and goods of Chinese origin in this category may be subject to Section 301 tariffs, a cost factor that has prompted some importers to qualify alternative sources in Germany, Japan, and Italy.
