Digestive enzyme

When evaluating digestive enzymes, the most critical factor is Enzyme Activity (Potency) rather than just weight in milligrams. Ensure the supplier provides activity units such as HUT (Protease), DU (Amylase), CU (Cellulase), and FIP/LU (Lipase). You should prioritize Multi-Enzyme Blends that cover a broad pH range to ensure effectiveness throughout the entire digestive tract. Additionally, verify the Source of Enzymes, distinguishing between animal-derived (like Pancreatin) and Plant-based or Fungal-derived (like Aspergillus oryzae), as the latter are often preferred for their stability and suitability for vegan markets.

As a health supplement, compliance is non-negotiable. You must require the supplier to provide GMP (Good Manufacturing Practice) and ISO 22000 or HACCP certifications to ensure food safety. For specific markets like the US, products must be manufactured in FDA-registered facilities, and for the EU, they must comply with EFSA regulations. Furthermore, check for Third-Party Lab Testing (COA - Certificate of Analysis) for every batch to confirm the absence of heavy metals (Lead, Mercury, Arsenic) and microbial contaminants like E. coli or Salmonella.

Enzymes are proteins and can be sensitive to heat and moisture. Inquire about the Encapsulation Technology used; for instance, Delayed-Release (DR) capsules or enteric coatings protect enzymes from stomach acid. Ask for Stability Testing Data to confirm that the enzyme activity remains at the claimed level until the expiration date. For bulk powder, ensure the packaging uses Moisture-proof and Light-shielding materials like vacuum-sealed aluminum foil bags.

Professional suppliers on Made-in-China.com should offer flexible Private Labeling (OEM) services. This includes Custom Formulation (e.g., adding probiotics or ginger/peppermint for synergistic effects), various dosage forms like Capsules, Tablets, or Powder Sachets, and sustainable packaging options. Ensure the supplier can provide Label Compliance Reviews to make sure your branding meets the regulatory requirements of the destination country.

Always request a Pre-shipment Inspection (PSI) conducted by a third-party agency like SGS or Intertek. Specifically, instruct them to perform a Random Sampling for Activity Assay to verify that the potency matches the proforma invoice. Using Trade Terms like FOB combined with secure payment methods on Made-in-China.com can provide a layer of financial security until the goods are verified.

Focus your negotiation on Tiered Pricing based on Activity Levels rather than just volume. Request a Sample Order first to test the market and product stability. For long-term partnerships, negotiate a Quality Guarantee Clause where the supplier bears the cost of returns or replacements if the enzyme activity drops below 90% of the specification within the first year of storage.

Since enzymes are heat-sensitive, avoid shipping during peak summer months if using standard sea freight. For high-value concentrated enzymes, Air Freight is recommended to minimize transit time. Ensure the shipping documents include a Material Safety Data Sheet (MSDS) and a Non-Dangerous Goods Declaration to prevent customs delays. Always clarify the Incoterms clearly; for beginners, CIF (Cost, Insurance, and Freight) might be easier, but FOB gives you more control over the shipping environment.

Customs requirements for supplements are strict. Ensure all labels are in the Local Language of the destination country and include a full ingredient list. You must provide a Health Certificate and a Certificate of Origin. It is highly recommended to consult with a Local Customs Broker before the goods depart to ensure the HS Code (typically under Chapter 35 for enzymes or Chapter 21 for food supplements) is correctly applied to avoid heavy fines or seizure.
