As a new-type foreign trade service provider driven by both technology transformation and foreign trade services, HiSiaddi has established a "1+2+3+4=1" service system and can supply original factory goods of 2,4,7,9-tetramethyl-5-decyne-4,7-diol from multiple well-known brands.
As a foreign trade service provider with independent R&D capabilities, HiSiaddi has conducted multiple rounds of on-site inspections of manufacturers producing 2,4,7,9-tetramethyl-5-decyne-4,7-diol through technological transformation cooperation with manufacturers, accumulating objective and in-depth insights into different brands. Accordingly, we regularly analyze manufacturers of 2,4,7,9-tetramethyl-5-decyne-4,7-diol for clients to help them select matching products. Below is a brand recommendation case.
Please contact HiSiaddi customer service if you require further comparative analysis of brands and models.
The client is SWISSINK, a premium Swiss ink brand specializing in food-contact grade flexible packaging inks, high-end publication gravure inks and eco-friendly flexographic inks, with products supplied to renowned European food packaging enterprises and printing groups. Its TMDD (2,4,7,9-tetramethyl-5-decyne-4,7-diol) requirements include high purity, low odor, low impurities, heavy metal-free and stable batches, used for dynamic wetting, foam suppression and pinhole prevention in ink systems.
This was the client’s first procurement of TMDD from China, with zero understanding of domestic brands, models and quality tiers. After contacting 5 manufacturers, each only promoted its own brand without objective cross-brand comparisons or disclosure of peer weaknesses, leaving the client confused: unable to distinguish industrial-grade vs high-purity grade, unclear about model-scenario matching, and fearing low-quality raw materials that would compromise ink performance. The client entrusted HiSiaddi with neutral brand analysis, horizontal model comparison and precise matching product recommendations.
1. Blank brand awareness: The client only knew the Chinese name of TMDD, with no understanding of mainstream domestic brands, market share or quality positioning, unable to differentiate mid-to-high-end and low-end brands;
2. Unilateral manufacturer sales tactics: The 5 manufacturers each pushed their proprietary models (e.g. TL-104, JL-2021, TM-980), only highlighting self-advantages while concealing shortcomings and refusing to comment on competitors, eliminating opportunities for horizontal comparison;
3. Confusion over model matching: Chaotic labeling across brands (97%/98%/99% purity, industrial/high-purity grades), with no clarity on which grades suit food-grade inks and which only fit general coatings;
4. Quality risk concerns: Fear of purchasing low-purity, high-impurity, strong-odor, batch-unstable low-end products that would trigger ink pinholes, craters, odors and non-compliance with food-contact standards.
HiSiaddi’s team conducted on-site visits to 3 manufacturers, compiled industry data and tested product samples to screen 5 mainstream domestic TMDD brands, delivering unbiased cross-brand comparisons across six dimensions: purity, impurity content, odor, stability, price and applicable scenarios, without favoring any single manufacturer.

Shenzhen Jihechang (Mid-Low-End, Small-Batch Spot Supply) Core model: TL-104 (97% industrial grade) Advantages: Abundant 25kg small-batch spot inventory, low minimum order quantity and low pricing; Disadvantages: Low purity, high impurities, strong odor and poor batch stability; Applicable scenarios: Low-end waterborne coatings, glues, general industrial additives.
10.
Aligned with the client’s requirements for food-grade inks, high purity, low odor and stable batches, HiSiaddi eliminated 3 mid-low-end brands and focused on 2 mid-to-high-end brands, recommending 3 models with clearly defined applicable scenarios for client selection.
Recommended model: TL-104E (99.5% high-purity grade) Recommendation rationale:
1. 99.5% purity with impurities ≤0.3% and mild odor, satisfying core indicators for food-grade inks;
2. Industry leader with ten-thousand-ton annual production capacity, exceptional batch consistency and short lead time (7 days);
3. Moderate unit price (125 RMB/kg), superior cost performance versus imported brands;
4. Complete SGS food-contact grade reports and REACH compliance statements compliant with European standards.
Recommended models: TMDD-997 (99.7% ultra-high-purity), TMDD-985 (98.5% high-purity) Recommendation rationale:
1. TMDD-997 delivers 99.7% purity, impurities ≤0.15%, water content ≤0.08% and zero odor, exceeding food-grade standards for the client’s new premium food ink product line;
2. TMDD-985 achieves 98.5% purity with impurities ≤0.25%, offering high cost performance for routine mass production of premium inks;
3. Flexible small-batch customization (minimum 5 tons per batch), dedicated independent production scheduling and exclusive quality control;
4. Complete certifications (SGS, REACH, FDA food-contact) with high recognition across European markets.
1. Prioritize mid-to-high-end brands: Eliminate Tuoyuan, Jiersheng and Shenzhen Jihechang to avoid quality risks from high impurities, strong odors and missing certifications;

We ultimately selected products fully matching our demands, resolving our biggest challenge of asymmetric information."
The core difficulty of this case lay in overseas mid-to-high-end clients’ asymmetric information regarding Chinese TMDD brands, exacerbated by manufacturers’ one-sided sales tactics that prevented objective cross-brand comparison and led to selection confusion.
HiSiaddi’s core value stems from its neutral third-party identity, professional industry knowledge and data-backed objective analysis:
1. Unbiased cross-brand and cross-model comparison grounded in factual test data, without favoring any manufacturer;
2. Precise alignment with client mid-to-high-end and food-grade high-purity demands, filtering low-end options and locking matching models;
3. Mitigation of quality risks, reduction of decision-making costs and improvement of procurement efficiency for clients.
For overseas mid-to-high-end clients sourcing fine chemicals in China, selecting a neutral, professional and industry-savvy foreign trade partner is more critical than simple price comparison—it clears information barriers, enables accurate product selection, guarantees quality and avoids costly mispurchases, securing access to premium raw materials tailored to high-end products.
