9902.15.96 - New crankshafts of forged steel designed for use solely or principally with compression-ignition internal combustion piston engines, other than for vehicles of chapter 87, each measuring more than 1.86 m in length and weighing 453 kg or more (provided for in subheading 8483.10.30)

This HTS classification, 9902.15.96, specifically addresses new crankshafts manufactured from forged steel. These crankshafts are intended exclusively or primarily for use in compression-ignition internal combustion piston engines. A critical distinction for this classification is that these engines are *not* for vehicles falling under chapter 87 of the Harmonized Tariff Schedule. Furthermore, the physical dimensions of the crankshaft are significant: each must exceed 1.86 meters in length and weigh 453 kilograms or more. This HTS code represents a temporary classification provision, directing importers to consider the principal use rules and the specific product definitions found within subheading 8483.10.30 for primary classification before applying this temporary modifier.

Given that this is a leaf node within the HTS structure, there are no further subcategories to detail. The classification is highly specific, relying on a combination of material (forged steel), intended application (non-vehicle compression-ignition engines), and precise physical characteristics (length and weight). This specificity aims to capture a particular segment of large industrial engine components that might otherwise fall under broader headings. It is crucial for importers to confirm that their merchandise precisely meets all stated criteria to ensure correct declaration and compliance with any associated temporary legislation or import restrictions.
