What is HS 350110?
HS 350110 covers casein in its primary commercial forms — acid casein, rennet casein, and caseinates — all derived from skim milk through precipitation processes. It sits within Chapter 35 of the Harmonized System, which covers albuminoidal substances and modified starches. Customs agents should note that caseinates (such as sodium or calcium caseinate) may be classified separately under HS 350190 depending on their processing stage, so product specification verification at the point of import declaration is essential.
End-use applications span a wide industrial spectrum: food and nutrition (protein fortification, cheese analogues), industrial adhesives, paper and board coatings, water-based paints, and specialty plastics. This cross-sector demand profile means casein buyers often compete with both food-grade and technical-grade purchasers, which directly influences availability and pricing.
Top Sourcing Countries for Casein
New Zealand is the dominant global supplier of casein into India, commanding nearly two-thirds of import volume by value in 2023 — a structural position driven by New Zealand's world-scale dairy industry, efficient production costs, and long-standing export infrastructure. For Indian importers, New Zealand origin material represents the benchmark for both quality and supply reliability.
The Netherlands holds the second-largest share of India-bound casein imports. As a major processing and re-export hub for European dairy, Dutch-origin casein often reflects blended sourcing from across the EU, providing buyers with an alternative channel when Oceanian supply tightens. Germany also appears as an origin, though at a materially lower volume, reflecting its role as a specialty and technical-grade supplier rather than a bulk commodity exporter.
Spain, Italy, and Singapore each hold smaller but strategically relevant shares. Singapore's presence as an origin likely reflects transshipment or regional distribution activity rather than domestic production — a point worth verifying in supplier due diligence. The United States and United Kingdom contribute marginal volumes to India's import mix.
- New Zealand: Benchmark origin — high volume, consistent quality, cost-competitive at scale
- Netherlands: Strong secondary source, useful for diversification from Oceanian supply
- Germany / France: Specialty and technical grades, suitable for regulated industrial applications
- Singapore: Likely transshipment origin — verify actual production source before contracting
Import Duty Rates and Trade Agreements
India applies a 20% MFN (Most Favoured Nation) duty on casein imports from countries not covered by a preferential trade agreement. However, procurement managers should note an important anomaly: New Zealand — the dominant supplier — currently attracts a 30% MFN rate into India, as does Singapore, Spain, the UK, and Malaysia. This means the largest origin by volume faces a structurally higher tariff than the standard MFN baseline, adding meaningful cost pressure to landed pricing.
India does not yet have a free trade agreement with New Zealand or the European Union in force, meaning there are no preferential duty pathways available for the primary sourcing origins as of 2025. Procurement teams should monitor FTA negotiations between India and these regions closely, as any concluded agreement could materially shift the duty-adjusted cost competitiveness of New Zealand and EU origin casein. In the interim, total landed cost modelling must account for the 30% applicable rate where relevant.
Cost Drivers and Price Outlook
Casein pricing is primarily a function of global skim milk powder (SMP) and whole milk markets, since skim milk is the direct feedstock. Unlike many industrial chemicals, casein is not energy-sensitive in production — making crude oil price movements a secondary factor. The more relevant signals are dairy commodity cycles, seasonal milk production patterns in the Southern Hemisphere, and currency movements in NZD and EUR against the buyer's base currency.
Procurement managers should track Global Dairy Trade (GDT) auction results as a leading indicator for casein input costs. Periods of tight global milk supply — driven by weather events in New Zealand or Australia, or elevated domestic dairy demand — tend to push casein prices upward with a lag of one to two quarters. Industrial demand from adhesives and coatings sectors provides a secondary demand-side lever, particularly in construction-linked markets.
Compliance and Sourcing Considerations
Casein is not classified as a hazardous material or dual-use good, and transshipment risk for HS 350110 is assessed as low. That said, food-grade casein imports into India are subject to FSSAI (Food Safety and Standards Authority of India) compliance requirements, including mandatory testing, labelling, and importer registration. Industrial-grade casein may face different documentation requirements — buyers must clearly establish the intended end use with their supplier to ensure correct certification is provided.
For shipments routed through Singapore or other intermediate hubs, confirm the country of origin documentation carefully. Certificate of Origin accuracy is critical given the duty rate differential between origins — misdeclaration, even unintentional, carries customs penalty exposure.
How to Source Casein Efficiently
Effective procurement of HS 350110 starts with origin diversification. Over-reliance on a single Oceanian supplier creates exposure to seasonal supply shocks and currency risk. Qualifying a European secondary supplier — particularly from the Netherlands or Germany — provides a meaningful buffer without significant quality trade-offs.
- Request food-grade or industrial-grade certification upfront — specifications differ materially and affect regulatory compliance
- Confirm actual country of manufacture on all Certificates of Origin, particularly for Singapore-routed shipments
- Build duty cost into landed cost models using the applicable 30% rate for NZ, SG, ES, and GB origins
- Monitor GDT auction results quarterly as a forward-looking price signal
- Engage a licensed customs broker familiar with FSSAI requirements for food-grade consignments into India
- Consider forward contracts or volume commitments during Southern Hemisphere autumn (March–May) when NZ milk output peaks and spot availability is strongest
