RE: The tariff classification of LFX Synthetic Protein Isolate from China
Dear Mr. New:
In your letter dated January 26, 2026, on behalf of your client, All G Co. Pty. Ltd., you requested a tariff
classification ruling on LFX Synthetic Protein Isolate.
In your submission, you identify the subject product as LFX, a synthetic bio-equivalent lactoferrin protein
isolate produced through fermentation. You state that LFX is a multi-purpose ingredient used in a multitude
of industries and products, including cosmetics, pharmaceuticals, and food supplements. LFX is
bio-equivalent in structure and function to native lactoferrin and described as a light brown to pink
free-flowing powder that typically contains >93% protein by weight, <4.5% moisture, and <3.5% ash. LFX
supports new product development and reformulation without reliance on animal-derived sources.
The applicable subheading for LFX Synthetic Protein Isolate will be 3504.00.1000, Harmonized Tariff
Schedule of the United States (HTSUS), which provides for Peptones and their derivatives; other protein
substances and their derivatives, not elsewhere specified or included; hide powder, whether or not chromed:
Protein isolates. The general rate of duty will be 5 percent ad valorem.
The duties cited above are current as of this ruling’s issuance. Duty rates are provided for your convenience
and are subject to change. The text of the most recent HTSUS and the accompanying duty rates are provided
at https://hts.usitc.gov/.
This ruling does not address the applicability of any additional duties, taxes, fees, exactions and/or other
charges, which may apply to the goods discussed herein. This includes, but is not limited to, tariffs and other
duties as provided for in Subchapter III to Chapter 99, HTSUS. Thus, for example, in addition to the
classification stated above, the merchandise covered by this ruling may also need to be reported with either
the Chapter 99 provision under which an additional tariff applies or one of the Chapter 99 provisions
covering exceptions to such tariffs.
