| Product identity | Calcium alpha-ketoglutarate, commonly abbreviated as Calcium AKG; supplied as a dry powder. | Chemical name, CAS information where applicable, molecular formula, assay method, and whether the material is a defined salt or a blend. | Prevents comparison of materials with different calcium content, purity, or formulation status. |
| Typical assay target | A commercial specification may target approximately 98.0% or higher by the supplier’s stated assay method. | Certificate of Analysis, test method, assay basis, test date, batch number, and independent laboratory verification options. | Higher and independently verified specifications generally increase cost but reduce quality and customer-complaint risk. |
| Indicative bulk price: 25–99 kg | Approximately US$28–55 per kg for standard non-custom material, before freight, duties, testing, and taxes. | Incoterm, currency, validity period, payment terms, included testing, and whether the quotation is for food, supplement, or technical grade. | Small wholesale orders usually carry higher unit costs because production, documentation, and handling charges are spread over fewer kilograms. |
| Indicative bulk price: 100–499 kg | Approximately US$20–40 per kg under a standard specification and ordinary commercial packaging. | Price break, production lead time, batch size, pallet configuration, and whether a pre-shipment sample is included. | This quantity often provides a useful balance between lower unit pricing and manageable inventory exposure. |
| Indicative bulk price: 500–999 kg | Approximately US$16–32 per kg, depending on assay, documentation, packaging, origin, and payment terms. | Annual volume commitment, reserved production capacity, price-adjustment clauses, and quality-release procedure. | Larger orders can reduce unit cost, but storage, working capital, and shelf-life management become more important. |
| Indicative bulk price: 1,000 kg or more | Approximately US$13–27 per kg for repeat bulk purchasing; contract pricing is normally negotiated individually. | Monthly forecast, minimum annual volume, payment security, production slots, inspection rights, and change-control terms. | The lowest unit price may require full-container or scheduled production commitments and may exclude destination costs. |
| Minimum order quantity | Common commercial starting points are 25 kg, 100 kg, 500 kg, or one metric ton, depending on the manufacturing route and packaging format. | Whether the MOQ applies per product, per batch, per assay specification, or per shipment. | A lower MOQ is valuable for market testing; a higher MOQ usually supports better pricing but increases inventory risk. |
| Standard packaging | Typical options include 20–25 kg fiber drums, HDPE drums, or multi-wall bags with an inner liner. | Net weight, liner material, tamper evidence, palletization, moisture barrier, and packaging compliance for the destination market. | Drums generally provide better protection and stacking stability; bags can reduce packaging cost and shipping weight. |
| Custom packaging | Private-label or customized retail packaging normally requires separate artwork approval, tooling or printing charges, and a higher MOQ. | Artwork ownership, language requirements, barcode rules, print proof, packaging lead time, and unused-material liability. | Customization can improve market readiness but commonly adds lead time and non-recurring costs. |
| Shelf-life and storage | A dry powder may commonly be assigned a 24–36 month shelf life when stored sealed in a cool, dry, low-humidity environment; the approved specification controls. | Real-time or accelerated stability data, retest date, recommended temperature and humidity, and opened-container instructions. | Longer validated shelf life can reduce write-offs, but it should not be assumed without supporting stability documentation. |
| Quality documentation | A professional bulk shipment should normally include a batch-specific COA and may include SDS, allergen statement, non-GMO statement, and microbiological results. | Document revision control, specification limits, laboratory accreditation, traceability records, and change-notification policy. | Complete documentation reduces import delays and supports customer, auditor, and regulator inquiries. |
| Contaminant testing | Testing commonly considered for supplement ingredients includes heavy metals, microbiology, residual solvents where relevant, and adulterant screening. | Country-specific limits, analytical methods, reporting units, detection limits, and whether testing is performed on every lot or periodically. | Destination-market compliance may require additional tests that are not included in the base quotation. |
| Production lead time | Approximately 2–6 weeks for standard stocked or scheduled material; custom specifications and packaging may require longer. | Lead time starts after payment, specification approval, artwork approval, or purchase-order confirmation. | A short quoted lead time is not meaningful unless the supplier defines the starting point and quality-release process. |
| Sample policy | Evaluation samples are often 50–500 g; sample and courier fees may be charged or credited against a confirmed order. | Sample batch number, sample COA, representative production status, and whether the sample is from commercial stock. | A production-representative sample gives more useful information than an untraceable laboratory sample. |
| Shipping mode | Air freight is faster for samples and small orders; ocean freight is usually more economical for palletized or container-volume shipments. | Gross weight, dimensions, pallet count, dangerous-goods classification, freight quotation validity, and estimated transit time. | The cheapest product quotation may not produce the lowest landed cost after freight and destination handling are added. |
| Incoterms and landed cost | Common quotation bases include EXW, FOB, CIF, and DDP; responsibilities differ for freight, insurance, customs, duties, and delivery. | Named place, import-of-record responsibility, tariff classification, customs documents, insurance coverage, and destination charges. | Compare suppliers using delivered cost per kilogram, not product price alone. |
| Payment terms | New transactions commonly use full or partial advance payment; established relationships may qualify for negotiated balance terms. | Deposit percentage, payment milestone, bank-account verification, inspection holdback, and refund or claim procedure. | Payment structure affects cash flow and should be assessed together with inspection and dispute protections. |
