1. Our Sourcing Philosophy

Our sourcing philosophy is built on four core principles that guide every decision we make about the ingredients and materials that go into our products:

These principles are non-negotiable. They inform every supplier relationship we enter, every raw material we purchase, and every product we bring to market. When we face a choice between lower cost and higher standards, we choose the standard every time.

2. Raw Material Standards

Every raw material used in Southern Aminos products must meet stringent quality criteria before it is considered for purchase. Our raw material standards are among the most rigorous in the industry and cover the following areas:

We categorize our raw materials into two groups, each with specific sourcing requirements:

Any raw material that fails to meet our standards upon receipt — regardless of the supplier’s CoA — is rejected and returned. We never make exceptions to our quality thresholds for cost or convenience reasons.

3. Supplier Qualification

We do not work with just any supplier. Every potential supplier must undergo a comprehensive qualification process before we purchase a single gram of material from them. Our qualification process includes the following steps:

We maintain an Approved Supplier List (ASL) that is reviewed and updated at least annually. New suppliers are added only through the full qualification process — we never make exceptions for expedited orders or cost savings.

4. Quality Verification Process

Every batch of raw material that arrives at our facility undergoes a multi-step verification process before it is released for use in production. This process ensures that what we receive matches what was ordered and what the supplier’s CoA claims.

No raw material is released for production until all three verification steps are complete and documented. If any step fails, the batch is quarantined, the supplier is notified, and a corrective action process is initiated. Batches that cannot be brought into compliance are rejected and returned or destroyed.

5. Country of Origin Disclosure

We believe in full disclosure regarding where our ingredients come from. Below is a general overview of our primary sourcing regions and the types of materials we source from each:

6. Supply Chain Integrity

Maintaining the integrity of our supply chain is critical to ensuring the quality and safety of our products. We implement multiple safeguards to prevent contamination, adulteration, substitution, and other supply chain risks:

• Direct Supplier Relationships: We work directly with manufacturers whenever possible, minimizing the number of intermediaries in our supply chain. This reduces the risk of mislabeling, contamination, or substitution that can occur through distributors and brokers.
• Tamper-Evident Packaging: All raw materials are shipped in tamper-evident packaging. We inspect seals and packaging integrity upon receipt and document any discrepancies.
• Lot-Level Tracking: Every batch is assigned a unique internal lot number that is linked to the supplier’s lot number, the Certificate of Analysis, test results, and the final products in which it was used.
• Temperature-Controlled Logistics: Temperature-sensitive materials are shipped under controlled conditions with temperature monitoring devices. We verify temperature logs upon receipt.
• Counterfeit Prevention: We employ analytical fingerprinting techniques to verify the identity of incoming materials against known reference standards, making it extremely difficult for counterfeit or substituted materials to enter our supply chain.

In the event of a supply chain disruption, quality issue, or safety concern, our chain-of-custody documentation allows us to rapidly identify and isolate affected batches, notify customers, and implement corrective actions.

7. Third-Party Testing

Independent third-party testing is the cornerstone of our quality assurance program. We do not rely solely on our suppliers’ Certificates of Analysis or our own in-house testing — every batch of raw material and every finished product batch is tested by an independent, accredited laboratory.

Our third-party testing panels include, at minimum:

Our third-party laboratories are ISO/IEC 17025 accredited and operate independently of both Southern Aminos and our suppliers. Test results are maintained on file and are available to customers upon request for any product they have purchased.

If a batch fails any third-party test, it is immediately quarantined and not released for production or sale. The supplier is notified, and a root cause investigation is initiated. We maintain a zero-tolerance policy for batches that fail purity or safety testing — there are no exceptions and no re-testing to achieve a passing result.

8. Ingredient Traceability

Full ingredient traceability means that for any Southern Aminos product, we can trace every ingredient back through the supply chain to its original source. Our traceability system captures the following data points for every ingredient in every batch:

• Original manufacturer name, address, and registration number
• Country of origin and country of manufacture
• Supplier lot number and our internal lot number
• Manufacturer’s Certificate of Analysis with full test results
• Our internal incoming inspection results
• Third-party laboratory test report with accreditation information
• Date of receipt, storage conditions, and expiration date
• The specific finished product lot numbers in which the ingredient was used

This level of traceability enables rapid and precise recalls if ever necessary, and allows us to provide customers with complete sourcing history for any product they purchase. We retain all traceability records for a minimum of five (5) years beyond the expiration date of the finished product.

9. Ethical Sourcing Practices

Our commitment to transparency extends beyond quality and purity to encompass the ethical dimensions of our supply chain. We expect all suppliers to adhere to the following ethical standards:

• Fair Labor Practices: No forced labor, child labor, or exploitative labor practices at any point in the supply chain. Workers must be paid fair wages and work under safe conditions.
• No Animal Testing: We do not conduct or commission animal testing on our products, and we give preference to suppliers who have committed to cruelty-free practices.
• Anti-Corruption: No bribery, kickbacks, or corrupt practices in supplier selection, qualification, or ongoing business relationships.
• Intellectual Property: All sourcing is conducted in compliance with intellectual property laws, patent protections, and trade secret regulations.

Suppliers are required to certify their compliance with these ethical standards as part of the qualification process. We take allegations of ethical violations seriously and will investigate and take appropriate action, up to and including immediate termination of the supplier relationship.

10. Environmental Responsibility

We recognize that our sourcing decisions have environmental implications, and we are committed to minimizing our environmental footprint throughout the supply chain. Our environmental commitments include:

• Prioritizing suppliers who implement environmentally responsible manufacturing processes, including waste reduction, water recycling, and energy efficiency programs
• Selecting packaging materials that are recyclable, biodegradable, or made from post-consumer recycled content where feasible without compromising product integrity
• Consolidating shipments and optimizing logistics to reduce carbon emissions from transportation
• Ensuring proper disposal of expired, rejected, or recalled materials in compliance with all environmental regulations
• Evaluating the environmental impact of new suppliers as part of the qualification process and giving preference to suppliers with strong environmental management systems

We acknowledge that environmental responsibility is an ongoing journey, not a destination. We continuously evaluate our practices, seek out more sustainable alternatives, and set progressively ambitious environmental targets for our supply chain.

11. Manufacturing Standards

While sourcing is the first step, maintaining quality through manufacturing is equally important. Our manufacturing and packaging processes adhere to the following standards:

Every finished product batch undergoes a final quality check that includes verification of fill weight, label accuracy, packaging integrity, and a review of all associated documentation before it is approved for shipment to customers.

12. Documentation & Records

Comprehensive documentation is the backbone of our transparency commitment. We maintain detailed records for every aspect of our sourcing and quality assurance processes. The following documents are maintained for every product batch:

All records are maintained for a minimum of five (5) years beyond the expiration date of the relevant product. Customers may request copies of third-party test reports and Certificates of Analysis for products they have purchased by contacting us with their order number.

13. Continuous Improvement

We do not view our sourcing practices as static. We are committed to continuous improvement in every aspect of our supply chain, driven by the following mechanisms:

• Annual Supplier Reviews: Every approved supplier undergoes a comprehensive annual review that evaluates quality performance, delivery reliability, responsiveness to issues, and continued compliance with our standards.
• Periodic Re-Audits: Suppliers are re-audited on a risk-based schedule, with higher-risk suppliers audited more frequently. Unannounced audits may be conducted at our discretion.
• Industry Benchmarking: We actively monitor industry developments, regulatory changes, and best practices in supply chain management to identify opportunities to strengthen our processes.
• Customer Feedback Integration: We value customer feedback on product quality and use it as an input to our continuous improvement process. Every quality-related customer inquiry is investigated and documented.
• Testing Method Advancement: We regularly evaluate new analytical methods and technologies that can provide more accurate, comprehensive, or efficient testing of our materials and products.

We publish an annual Sourcing Transparency Report that summarizes key metrics, audit findings, supplier performance data, and improvement initiatives. This report is made available to customers and the public as part of our commitment to accountability.
