HiSiaddi is an innovative foreign trade service provider driven by both technology transformation and export business. We have established a "1+2+3+4=1" service system and can supply original MSM raw materials from multiple well-known brand manufacturers. As a tech-driven foreign trade enterprise, HiSiaddi has repeatedly resolved customized MSM product demands for clients through technological transformation cooperation with factories and precise market insight. Below is a case where HiSiaddi delivered a customized MSM solution.
Contact HiSiaddi customer service if you require customized service support.
Purchaser: ProSport Elite, a premium sports dietary supplement group based in California, USA. The company specializes in joint capsules for professional athletes, liquid oral solutions and effervescent sports powder. Its products are sold at high-end fitness chains, private sports rehabilitation clinics and organic supermarkets across the United States. Its raw materials comply with five strict standards: USP Pharmacopoeia, FDA GRAS, Non-GMO, Kosher certification and EU food access standards. Previously, the brand sourced MSM raw materials long-term from major domestic API manufacturers in North America.
To optimize supply chain costs and shorten delivery cycles, the client independently contacted 3 domestic MSM factories and put forward differentiated multi-spec customization requirements. However, these domestic manufacturers only mass-produced standard MSM with regular particle sizes per national standards and failed to deliver customized indicators. Multiple sampling trials ended in failure, so the client entrusted HiSiaddi to fully coordinate customized R&D, sampling and mass production implementation. The client set three mandatory customized indicators rarely seen in the industry:
1. Dual particle size separation customization: ① 120-mesh ultra-fine high-purity powder for capsules (no bridging or sticking on punches during automatic capsule filling); ② 30-mesh large crystalline particles for effervescent oral liquids (low-temperature fast dissolution, no residues or suspended particles);
2. Purity and impurity customization: USP-grade 99.95% ultra-high purity, free DMSO residual <5ppm, heavy metal lead and arsenic <0.5ppm to eliminate slight odor precipitation during production. Conventional domestic MSM generally contains 15~30ppm DMSO residual, failing to meet the standard;
3. Anti-caking agent-free customization: Exogenous anti-caking additives such as silicon dioxide and tricalcium phosphate are prohibited. Natural anti-caking performance is achieved via recrystallization technology to fit the brand’s fully vegetarian and clean-label formulation requirements.
1. Factories prioritize mass production and refuse production line modifications for niche customization The 3 domestic MSM manufacturers mainly produce standard 40~80-mesh products with continuous mass production lines. Adjusting crystallization temperature control and screening equipment requires production line shutdowns and process modification. Factories prioritize selling in-stock standard products and rejected refined particle separation due to high customization transformation costs.
2. Refining process limitations fail to meet ultra-strict impurity limits Conventional atmospheric distillation leaves incomplete removal of DMSO byproducts, resulting in DMSO residual exceeding the <5ppm limit. Without supporting multi-stage vacuum rectification production lines, all small trial samples failed third-party testing.
3. Single anti-caking solution relies on external additives Domestic universal formulas add food-grade silicon dioxide for anti-caking purposes. Restricted by equipment, factories cannot improve crystal morphology via recrystallization to achieve natural looseness, conflicting with the client’s "zero exogenous additives" customization clause, rendering all trial products invalid.
Relying on designated top-tier domestic MSM manufacturers (two GMP-certified factories: Tianjin Baofeng and Hunan Ansen), HiSiaddi collaborated with factory R&D departments to split processes and deliver the customization in four phases: formula & process optimization → small-batch sampling → pilot trial production → mass production finalization.
1. Production line segmented transformation to realize dual particle size customized production HiSiaddi coordinated factories to activate dedicated batch refining production workshops with two sets of independent crystallization temperature control parameters:
· 30-mesh large crystals: Slow cooling rate of 0.3℃/h to form large, regular crystals via crystal growth, followed by screening with customized stainless steel classifying sieves;
· 120-mesh ultra-fine powder: Low-temperature vacuum crushing + air classification to avoid agglomeration of ultra-fine dust. Three consecutive batches were tested for angle of repose and flowability, matching the parameters of the client’s filling equipment.
1. Upgraded multi-stage vacuum rectification to strictly control trace impurities Abandoning atmospheric distillation, a new process combining three-stage negative-pressure rectification and deep activated carbon adsorption was adopted to remove residual DMSO and inorganic impurities in sections. CNAS third-party testing showed DMSO residual at 3.2ppm and all heavy metals below 0.3ppm, breaking the upper limit of conventional factory processes and complying with USP and U.S. import drug supervision standards.
2. Crystal morphology modification replaces external additives to achieve additive-free anti-caking HiSiaddi collaborated with R&D teams to adjust feed liquid pH and cooling curves to alter MSM crystal structure. Natural gaps between crystals maintain loose texture without any anti-caking additives, satisfying the client’s clean vegetarian label requirements and solving caking issues under high-temperature storage.
3. Customized packaging and compliance documents as supporting services Custom 20kg food-grade paper drums with aluminum foil inner liners (moisture-proof and light-shielding) were produced per client requirements. Bilingual Certificates of Analysis (COA), Kosher, Non-GMO and full sets of export compliance documents were provided simultaneously for U.S. customs clearance and brand filing.
1. Three batches of samples were shipped to U.S. laboratories for full-index testing; both particle sizes of MSM passed all USP indicators and showed zero malfunctions during capsule filling and effervescent production trials.
2. The client finalized an annual framework order of 12 tons: 6.8 tons of 30-mesh crystals and 5.2 tons of 120-mesh ultra-fine powder, shipped in 6 batches via constant-temperature containers. After raw material launch, the yield of capsule filling rose from 87% (using ordinary domestic raw materials previously) to 99.6%, and effervescent liquid remained clear without sediment. Finished products were successfully launched across high-end U.S. sales channels.
3. Compared with original North American raw material suppliers, comprehensive procurement costs dropped by 27%, and sea transit time was shortened from 48 days to 22 days.
1. Subsequent Business Expansion In the following year, the client expanded into high-end rehabilitation markets in Canada and Australia and added customized cosmetic-grade low-irritation MSM for external skincare. HiSiaddi fully managed the implementation of all customized raw material orders. Supported by the endorsement of this high-end North American brand, partner factories upgraded refined MSM customized production lines and secured fixed customized orders from three additional European and American premium nutrition brands.
2. Summary of Industry Pain Points Domestic MSM manufacturers focus on large-volume standardized production with fixed production lines and low motivation for customized R&D, leaving them unable to address refined clean-formula customization demands from overseas mid-to-high-end brands. Overseas premium brands lack familiarity with the process transformation and customized R&D capacity limits of domestic factories, and independent procurement often leads to customization failures. As a third-party foreign trade service provider, HiSiaddi connects client demands with factory technical transformation resources, delivers exclusive customization from the source of production processes, breaks information barriers between Chinese and foreign customization markets, and enables localized customized production of high-end raw materials for global markets.
