35 Albuminoidal substances; modified starches; glues; enzymes
The broadest level of the Harmonized System. Pick the heading below that fits your goods, then the six-digit code under it — that last one is what you declare.

- 35 Chapter Albuminoidal substances; modified starches; glues; enzymes
- —— Heading Pick one of the 7 headings below
- —— Subheading Six digits, the level every country shares
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.

The wording above is the Harmonized System nomenclature as published by the World Customs Organization, HS 2022 edition. It is a classification reference, not a tariff: it carries no duty rates, and it stops at six digits — the importing country adds its own beyond that.
Classification is decided by the General Rules of Interpretation and the section and chapter notes, and it is the importing country’s customs authority that makes it binding.
Shipping goods from chapter 35? A customs hold shows up as a milestone that stops moving — follow the container or the air waybill from departure to delivery.

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.
Pick the heading below that describes the goods, then the six-digit subheading under it. Six digits is the level the Harmonized System defines and the level customs everywhere recognises; anything beyond that is added by the importing country.
The General Rules of Interpretation, read together with the notes to Section VI and to chapter 35. A description that reads right is not enough on its own — the notes routinely pull goods out of the chapter they obviously belong to and put them somewhere else. Where duty or licensing turns on the answer, ask the importing country’s customs authority for a binding ruling.
A wrong or missing code is one of the common reasons customs holds a container, and a hold shows up as a milestone that stops moving. Watch for it in the container tracking app, on the air waybill in the air cargo tracker, or through the tracking API.
