Section VI · Chemical Products · Chapter 35
Albuminoidal substances; modified starches; glues; enzymes
About chapter 35
Chapter 35 covers albuminoidal substances; modified starches; glues; enzymes: protein-based and starch-derived industrial materials used in adhesives, food processing, textiles and paper manufacturing.
Classification tip: Enzymes used in food processing versus industrial enzymes (for detergents or textiles) are classified the same way here regardless of end use: the chemical nature of the product, not its application, drives the code.

Codes and descriptions follow the WCO six-digit Harmonized System nomenclature. National tariff schedules extend these to 8–13 digits and set the actual duty rate, so confirm the full code for your destination country with your customs broker before filing. To copy a code, hover a row and use the copy button; every code has 3501-style dot notation ready for your commercial invoice.
Chapter 35 FAQ
What does HS code chapter 35 cover?
Chapter 35 of the Harmonized System covers: albuminoidal substances; modified starches; glues; enzymes. It belongs to section VI (Chemical Products) and contains 7 four-digit headings, 3501–3507.
How many HS codes are in chapter 35?
Chapter 35 contains 7 four-digit headings and 15 six-digit subheadings. Countries subdivide these further (8–13 digits) in their national tariff schedules, so the full national count is larger.
Is HS code 3501 the same in every country?
Yes. The six-digit level of every code in this chapter is harmonised by the World Customs Organization and identical in all member countries. Digits beyond the sixth (for example the US 10-digit HTS or the EU 8-digit CN) are national and set the actual duty rate.
How do I choose the right code within chapter 35?
Work from the four-digit heading down: pick the heading that best matches your product, then the six-digit subheading that matches its material, form or processing. If two codes seem to fit, customs rules (the General Rules of Interpretation) decide, and when in doubt, confirm with your customs broker before filing.
