3907.70.00.00 - Poly(lactic acid)

This HTS category, 3907.70.00.00, specifically classifies poly(lactic acid) (PLA) in its primary forms. PLA is a biodegradable and biocompatible thermoplastic polymer derived from renewable resources such as corn starch, sugarcane, or cassava. It is commonly encountered as pellets, granules, powders, or liquids intended for further processing into various finished goods. Its classification under Chapter 39 signifies its status as a plastic material.

Distinguishing this category from its siblings, it is important to note that 3907.70.00.00 is exclusively for poly(lactic acid). Other categories within heading 3907 cover distinct polymer families. For instance, 3907.10.00.00 pertains to polyacetals, 3907.30.00.00 covers epoxide resins, and 3907.40.00.00 is for polycarbonates, each possessing unique chemical structures and properties. This specificity ensures that PLA is correctly identified and not grouped with these dissimilar plastic types.

As a leaf node, 3907.70.00.00 has no further subcategories. Therefore, classification within this code relies on correctly identifying the material as poly(lactic acid) in a primary form. Common applications of PLA in its primary form include manufacturing biodegradable packaging, disposable cutlery, 3D printing filaments, and certain medical implants. The emphasis for classification here is on the material itself rather than its end-use application.
