HS 350710 Rennet and concentrates thereof
Quick Answer: Rennet and concentrates thereof, classified under HS code 350710, enter the UK duty-free, the US duty-free under the MFN rate, and the EU at 6.30% ad valorem. This HS code specifically covers rennet, a complex of enzymes produced in the stomachs of young ruminant mammals, and its concentrated forms. Rennet is primarily used in cheesemaking to coagulate milk. Importers should be aware that while duty rates are favorable in the UK and US, the EU imposes a tariff. According to CustomTariffs data, understanding these varying rates is crucial for accurate landed cost calculations and compliance.

How to Classify This HS Code?
What products does HS 350710 cover?
This subheading covers rennet and concentrates thereof, as defined by the World Customs Organization (WCO) Harmonized System Nomenclature. Rennet is a complex of enzymes produced in the stomachs of young ruminant animals, primarily chymosin, used in cheesemaking to coagulate milk. Concentrates are preparations of rennet that have been processed to increase their enzymatic activity, often standardized for specific applications. Official definitions from sources like the USITC Harmonized Tariff Schedule (HTS) and the EU's TARIC database confirm that this classification applies to both crude and purified forms of rennet and its concentrated preparations.
What falls outside HS 350710?
The following products are excluded from HS 350710: enzymes of animal origin not specifically rennet or its concentrates, such as pepsin or trypsin, which are classified under other headings within Chapter 35. Additionally, microbial rennets or vegetable-based coagulants used in cheesemaking, even if functionally similar, are not classified here. For instance, microbial coagulants derived from fungi or bacteria are typically classified under HS 350790, and plant-based coagulants would fall under their respective material classifications, not this specific rennet code.
What are common classification mistakes for HS 350710?
A common error is misclassifying microbial or vegetable-based coagulants as rennet under HS 350710. According to General Rule of Interpretation (GRI) 1, classification is determined by the terms of the headings and any relative section or chapter notes. HS 3507 specifically refers to "enzymes of animal origin" for the primary subheadings, including rennet. Products derived from non-animal sources, even if used for similar purposes, do not meet this fundamental requirement and must be classified elsewhere, often under HS 350790 for other enzymes.
How should importers classify products under HS 350710?
The correct procedure for classifying products under HS 350710 involves confirming the origin and nature of the coagulating agent. Importers and customs brokers must review product specifications, supplier declarations, and any laboratory analysis to ascertain if the product is indeed rennet derived from animal stomachs or a concentrate thereof. If the product is an enzyme preparation, its specific enzymatic activity and source material are crucial for accurate classification, referencing the WCO HS Explanatory Notes and national tariff schedules like the USITC HTS or UK Trade Tariff.
How is the duty calculated for products under HS 350710?
A shipment of 100 kilograms of liquid rennet concentrate, declared at a customs value of $5,000 USD, would attract a US duty of $350.00. This is calculated using the Most Favored Nation (MFN) duty rate of 7.0% ad valorem, applied to the declared value. The calculation is $5,000 USD × 7.0% = $350.00. This rate is published in the USITC Harmonized Tariff Schedule (HTS) under subheading 350710.0000.
Which trade agreements reduce duties for HS 350710?
Several free trade agreements may reduce the applicable duty rate for HS 350710, including the United States-Mexico-Canada Agreement (USMCA), which can offer Free (0%) duty rates for originating goods from Canada and Mexico. Additionally, the Generalized System of Preferences (GSP) may provide reduced or Free duty rates for eligible products from developing countries. To claim these preferences, a valid Certificate of Origin or a self-certified origin statement, as per the specific requirements of the importing country's customs authority, is typically required.

FAQ
What are the typical import duty rates for HS code 350710 (Rennet and concentrates thereof)?
The import duty rates for HS code 350710 can vary significantly by country. For example, under the US Harmonized Tariff Schedule (HTS), the Most Favored Nation (MFN) duty rate is Free. However, other countries may have different rates. For instance, the EU's TARIC system might list a rate of 0.00% or a specific ad valorem rate depending on the origin and specific product. Always consult the relevant national tariff schedule for the importing country, such as the USITC HTS, EU TARIC, or UK Trade Tariff, for the most accurate and up-to-date duty information applicable to your specific import.
How is rennet classified under HS code 350710, and what are the key classification criteria?
HS code 350710 covers 'Rennet and concentrates thereof.' Rennet is a complex set of enzymes produced in the stomachs of ruminant animals (like calves) or produced through microbial fermentation or recombinant DNA technology. Its primary function is to coagulate milk proteins, a crucial step in cheesemaking. Classification under 350710 hinges on the product's primary function and composition. It must be identifiable as rennet or a concentrated form of rennet, intended for use in dairy processing. Products that are primarily animal stomach contents without significant enzymatic activity for milk coagulation, or enzymes used for other purposes, would not be classified here.
What documentation is typically required when importing rennet under HS code 350710?
When importing rennet (HS 350710), standard import documentation is required, which generally includes a commercial invoice, packing list, and bill of lading or air waybill. Depending on the importing country's regulations and the source of the rennet, additional documents may be necessary. This could include a certificate of origin to claim preferential duty rates under trade agreements, and potentially health or veterinary certificates to ensure the product meets sanitary and phytosanitary standards, especially if derived from animal sources. It is advisable to consult with a customs broker or the importing country's customs authority for a comprehensive list.
How is the import duty for HS 350710 calculated, and can you provide an example?
Import duty calculation for HS code 350710 depends on the specific duty rate applied by the importing country. Duties can be ad valorem (a percentage of the value of the goods) or specific (a fixed amount per unit of quantity). For example, if a country applies a 6.30% ad valorem duty rate and you import rennet concentrate valued at $10,000 USD, the duty would be calculated as: $10,000 (value) × 6.30% (duty rate) = $630 USD. If there were also a specific duty, such as $0.50 per kilogram, and the shipment weighed 200 kg, the specific duty would be 200 kg × $0.50/kg = $100 USD. The total duty would be the sum of any applicable ad valorem and specific duties. Always verify the exact duty calculation method and rates with the official tariff schedule.
Do trade agreements, such as USMCA or EU Free Trade Agreements, affect the duty rates for HS code 350710?
Yes, trade agreements can significantly impact the duty rates for HS code 350710. For example, under the United States-Mexico-Canada Agreement (USMCA), goods originating from Canada or Mexico may qualify for preferential duty rates, often resulting in a 0% duty, provided they meet the rules of origin. Similarly, the European Union has numerous Free Trade Agreements (FTAs) with countries worldwide, which can reduce or eliminate duties on originating goods. To benefit from these agreements, importers must typically provide a certificate of origin and ensure the rennet and its concentrates meet the specific rules of origin stipulated in the relevant trade agreement. Consulting the official text of the trade agreement and the importing country's customs regulations is crucial.
