HS Code 3507Enzymes; prepared enzymes not elsewhere specified or included

What heading 3507 covers

Enzymes are proteins that speed up chemical reactions. Factories use them to make cheese, bread, drinks, detergents and textiles. When these goods cross a border, customs officers file them under heading 3507.

The heading sits in Section VI, which groups the chemical or allied industries. Inside that section it belongs to Chapter 35, next to the casein, gelatin, starch and glue headings.

The words "not elsewhere specified or included" can confuse people. They do not turn the heading into a dumping ground for leftovers. They only mean that if another heading names a product more exactly, that heading wins. For true enzymes, 3507 is the natural home.

Enzymes prepared under sub heading 3507: rennet and the rest

The heading splits into two subheadings. Tariff books often print them with a dot, as 3507.10 and 3507.90. Trade records drop the dot and show 350710 and 350790. Both forms point to the same goods.

The first is narrow. The second is wide and takes everything the first one does not.

• 350710 (3507.10): enzymes; rennet and concentrates thereof
• 350790 (3507.90): enzymes and prepared enzymes; other than rennet and concentrates thereof

How to pick between 350710 and 350790

Ask one question: is the product rennet, or a concentrate made from rennet? If yes, the answer is 350710. If it is any other enzyme or prepared enzyme, the answer is 350790.

Real products can be harder to read than this rule. A label may show only a trade name, or a blend may list many ingredients. Check the data sheet and compare it with the exact wording of each code. If doubt remains, run the item through the HS code classifier before you file a declaration or search for records.

Also check the neighbours. A product that is mainly a protein or a glue may belong in another heading, not here.

How 3507 differs from other Chapter 35 headings

Several Chapter 35 headings sound close to enzymes because they all deal with proteins, starches or glues. This list shows where each one stops. Each heading has its own page.

• 3502 is for albumins, including whey protein concentrates above the stated protein level, and albumin derivatives.
• 3503 is for gelatin and its derivatives, isinglass, and other animal glues.
• 3504 is for peptones, other protein substances and hide powder.
• 3505 is for dextrins, modified starches and glues based on them.
• 3506 is for prepared glues and other adhesives, including small retail packs.
