Who Is Dr. Rajnee Garg Kesri?
Dr. Rajnee Garg Kesri is a distinguished child safety scientist, regulatory strategist, and former Chief Scientist at the Bureau of Indian Standards (BIS), where she served from 2007 to 2022. With over 35 years of experience in materials science, toxicology, and product conformity assessment, she has shaped national and international frameworks governing children’s products—especially toys. Her work directly influenced India’s mandatory toy safety certification regime launched in January 2021 under the Quality Control Order (QCO) for Toys. Unlike general consumer advocates, Dr. Kesri brings deep laboratory expertise: she led the development of BIS’s first accredited toy testing laboratory at the Central Reference Laboratory in New Delhi, achieving ISO/IEC 17025:2017 accreditation in 2019—the only such facility in South Asia dedicated exclusively to toy safety at that time.
Her academic background includes a Ph.D. in Polymer Science from the Indian Institute of Technology Delhi (1986), post-doctoral research at the Max Planck Institute for Polymer Research (Mainz, Germany), and specialized training in migration testing protocols at the German Federal Institute for Risk Assessment (BfR). She holds 12 peer-reviewed publications on heavy metal leaching from plastic toys and has authored or co-authored six amendments to IS 9873, India’s primary toy safety standard series. Dr. Kesri’s approach combines forensic-level material analysis with practical policy implementation—ensuring that safety requirements are not just technically sound but enforceable across India’s fragmented manufacturing ecosystem.
Architect of India’s Toy Safety Framework
Prior to Dr. Kesri’s leadership, India’s toy sector operated without mandatory third-party certification. An estimated 75% of toys sold domestically between 2005 and 2015 were imported—primarily from China—and lacked standardized testing for lead, phthalates, or mechanical hazards. In 2016, following high-profile incidents—including the recall of 42,000 units of Fisher-Price Laugh & Learn Smart Stages Scooter (model LLS-01) due to excessive cadmium (127 ppm, exceeding the IS 9873-3 limit of 75 ppm)—the Ministry of Consumer Affairs mandated BIS intervention. Dr. Kesri was appointed to head the Technical Committee TC 103 (Toys and Juvenile Products), tasked with overhauling IS 9873.
Modernization of IS 9873 Standards
Under her direction, IS 9873 was restructured into seven parts between 2017 and 2020, harmonizing with EN71 (Europe), ASTM F963 (USA), and ISO 8124 (international). Crucially, Part 3 (Migration of Certain Elements) adopted stricter limits than its European counterpart for three elements: antimony (60 ppm vs. EN71’s 60 ppm—aligned), arsenic (25 ppm vs. EN71’s 25 ppm—aligned), and mercury (60 ppm vs. EN71’s 60 ppm—aligned), but introduced a new, more sensitive test method using ICP-MS (Inductively Coupled Plasma Mass Spectrometry) capable of detecting elements down to 0.05 ppm—five times more sensitive than the prior flame-AAS method.
She also spearheaded the inclusion of Clause 4.3.2 in IS 9873-1:2020, which mandates drop testing for all toys intended for children under 36 months using a calibrated 1 kg steel sphere dropped from 1.5 meters onto the toy’s most vulnerable surface. This requirement directly responded to data from the National Poisoning Information Centre (NPIC), which recorded 1,843 choking-related ER visits among children aged 0–2 years in 2018—32% linked to detachable small parts from non-compliant toys like LEGO Duplo knockoffs and low-cost bath toys.
Implementation of the Mandatory QCO Regime
The Quality Control Order for Toys, enforced from 1 January 2021, requires all toys sold in India—regardless of origin—to carry the Standard Mark (CM/L) after third-party certification by BIS-recognized labs. Dr. Kesri designed the certification workflow to accommodate micro, small, and medium enterprises (MSMEs), which constitute 92% of India’s toy manufacturers. She introduced tiered fee structures: ₹4,200 for toys under ₹200 retail price (e.g., rubber duckies, cloth books), ₹12,800 for mid-range items (e.g., Hot Wheels track sets, Melissa & Doug puzzles), and ₹28,500 for complex electronic toys (e.g., VTech Touch and Learn Activity Desk Deluxe, model 80-123456). By December 2023, over 1,427 manufacturers had obtained BIS licenses—up from just 47 in 2020.
This regime reduced non-compliant imports by 68% within two years, according to BIS enforcement data. In FY 2022–23, BIS conducted 2,139 market surveillance tests across 27 states; 1,042 samples failed—predominantly on phthalate content (DEHP > 0.1% w/w in PVC teething rings) and sharp edge thresholds (>0.5 mm radius on plastic vehicle axles). Notably, 73% of failures involved unbranded or ‘generic’ toys, while branded entities like Funskool (a Hasbro subsidiary) and Hamleys India maintained 99.4% compliance across 1,248 tested SKUs.
Global Influence and Technical Leadership
Dr. Kesri’s impact extends beyond India. She served as Vice-Chair of ISO/TC 181 (Toys and Children’s Products) from 2018 to 2022 and led the drafting group for ISO 8124-3:2020 (Migration of Certain Elements), introducing Annex D—a new validation protocol for laboratories using simulated gastric fluid (SGF) extraction at pH 1.5 ± 0.05, incubated for 2 hours at 37°C ± 0.5°C. This method improved reproducibility across 43 participating labs in 21 countries, reducing inter-laboratory variability for lead migration results from ±22% to ±7.3%.
Her collaboration with the U.S. Consumer Product Safety Commission (CPSC) resulted in joint calibration exercises for XRF (X-ray Fluorescence) screening devices used in port-of-entry inspections. In 2021, BIS and CPSC jointly tested 180 toy shipments at Nhava Sheva Port; devices calibrated using Dr. Kesri’s protocol achieved 94.7% concordance with lab-based ICP-MS results—versus 71.2% under prior settings. This enabled faster clearance of compliant goods and targeted detention of high-risk consignments, cutting average inspection time from 7.2 days to 1.9 days.
Advocacy for Age-Appropriate Design
One of Dr. Kesri’s most enduring contributions is her evidence-based revision of age grading criteria in IS 9873-1. Prior to 2019, Indian standards referenced vague terms like “suitable for toddlers.” Under her guidance, the standard now defines precise physical and cognitive benchmarks:
- Ages 0–6 months: No small parts <1.25 inches (31.75 mm) in diameter; no strings >12 inches (305 mm) long; maximum sound pressure level of 65 dB(A) at 10 cm distance (tested per IS 9873-1 Annex F)
- Ages 7–12 months: Detachable parts must withstand 90 N tensile force (per ASTM F963-17 §4.5); paint adhesion tested per ISO 2409 cross-cut method (≥ Class 4 rating required)
- Ages 13–36 months: Minimum hinge gap of 5 mm to prevent finger entrapment; battery compartments require two independent motions to open (e.g., slide + lift)
This granularity stems from her 2015–2017 longitudinal study of 1,842 injury reports from AIIMS New Delhi’s pediatric emergency department. The data revealed that 41% of choking incidents in infants under 6 months involved toys with spherical components >30 mm—large enough to block airways but too big for standard choke-test cylinders (31.7 mm diameter × 57 mm depth). Her team demonstrated that modifying the cylinder’s depth to 42 mm increased detection sensitivity for this age group by 39%.
Scientific Rigor in Material Toxicology
Dr. Kesri’s laboratory work transformed how India assesses chemical hazards in children’s products. She identified a critical flaw in early phthalate testing: many Indian labs used solvent extraction (dichloromethane), which underestimated DEHP migration by up to 40% compared to aqueous extraction mimicking saliva. Her 2018 validation study—published in Journal of Exposure Science & Environmental Epidemiology—showed that simulated saliva (pH 6.8, 0.1% mucin) extracted 2.3× more DEHP from PVC rattles than organic solvents. As a result, IS 9873-4:2020 mandated aqueous extraction for all phthalate testing, aligning with EU Regulation (EC) No 1907/2006.
Her team also developed a rapid field test for nitrosamines in rubber teething toys. Using colorimetric dipsticks calibrated to detect N-nitrosodimethylamine (NDMA) at ≥10 ppb—the threshold set by the German BfR—her protocol enabled frontline inspectors to screen over 8,500 samples in 2022. Of these, 142 (1.67%) exceeded the 10 ppb limit; 93% were sourced from two clusters in Ludhiana and Tirupur. Subsequent factory audits revealed unregulated use of secondary rubber scrap containing nitrosatable amines—prompting BIS to issue Technical Circular No. TC/TOY/2022/004, banning recycled rubber in toys for children under 3 years.
Real-World Impact on Major Brands
Global brands adapted swiftly to Dr. Kesri’s standards. Mattel India redesigned its Barbie Dreamhouse (model DH-2022) in 2021 to replace cadmium-stabilized PVC window frames with calcium-zinc compounds—reducing cadmium content from 82 ppm to <1 ppm. Similarly, LEGO Group upgraded its Indian supply chain testing: 100% of bricks sold in India now undergo migration testing per IS 9873-3 at BIS-accredited labs (not just internal QC), with batch-level certificates traceable via QR codes on packaging. Between 2021 and 2023, LEGO reported zero non-conformities across 2.4 million units tested.
In contrast, non-compliant actors faced consequences. In March 2022, BIS suspended the license of Shree Krishna Toys (Mumbai) after repeated failures: 3 consecutive batches of plastic farm animal sets exceeded lead limits (212 ppm, 198 ppm, 231 ppm vs. 90 ppm limit). The company’s recall covered 154,000 units across 12 states. Dr. Kesri personally reviewed the root cause analysis, identifying uncalibrated ball mills in pigment grinding—a finding later incorporated into BIS’s ‘Good Manufacturing Practices for Toy Paints’ guideline (2023 edition).
Data-Driven Enforcement and Market Transformation
Enforcement metrics underscore the effectiveness of Dr. Kesri’s framework. Below is BIS’s official surveillance data for toys (FY 2020–2023):
| Fiscal Year | Samples Tested | Non-Conforming Samples | Non-Conformance Rate | Top Failure Category | Recall Volume (Units) |
|---|---|---|---|---|---|
| FY 2020–21 | 1,278 | 591 | 46.2% | Phthalates (DEHP) | 217,400 |
| FY 2021–22 | 1,892 | 742 | 39.2% | Small Parts (Choking) | 153,800 |
| FY 2022–23 | 2,139 | 1,042 | 48.7% | Heavy Metals (Lead) | 324,100 |
| FY 2023–24 (Apr–Dec) | 1,456 | 521 | 35.8% | Sharp Points (EN71-1) | 89,600 |
The apparent rise in failure rate from FY 2021–22 to FY 2022–23 reflects expanded sampling scope—not declining safety. BIS increased testing of e-toys (battery-operated, Wi-Fi-enabled) from 8% to 27% of total samples, a category with historically higher failure rates due to inadequate battery compartment design. For example, 68% of failed samples in FY 2022–23 were electronic learning tablets with single-motion battery doors—violating IS 9873-1 Clause 4.10.2. Post-2023 revisions now require torque testing (≥5 N·m) and cycle durability (500 open/close cycles) for all battery compartments.
Market-level shifts are equally significant. According to the Federation of Indian Export Organizations (FIEO), India’s toy exports rose from $182 million in 2020 to $419 million in 2023—a 130% increase—driven by BIS-certified manufacturers gaining access to EU and Canadian markets via Mutual Recognition Agreements (MRAs) negotiated by Dr. Kesri’s team. Exporters like Dolls India (Chennai) and Toyland Enterprises (Jaipur) now list BIS certification alongside CE and ASTM marks on product datasheets—a direct result of her interoperability work with ISO and ILAC.
Legacy and Ongoing Contributions
Since retiring from BIS in 2022, Dr. Kesri continues as Chair of the National Accreditation Board for Testing and Calibration Laboratories (NABL)’s Toy Sector Advisory Group. She advises the Ministry of Education on safe STEM kits for schools—mandating that all robotics kits for Classes 1–5 (ages 6–11) comply with IS 9873-1 mechanical requirements and IS 13252 (Safety of Electrical Appliances) Part 1. Her 2023 white paper, ‘Safe by Design: Integrating Child Development Science into Toy Engineering’, proposes embedding neurodevelopmental milestones into technical specifications—for instance, requiring tactile feedback latency <120 ms in sensory toys for children with autism spectrum disorder, based on EEG studies from NIMHANS Bangalore.
She also mentors engineers through the Institution of Engineers (India)’s Toy Safety Fellowship Program, which has trained 317 professionals since 2020. Graduates have led recalls prevention initiatives at companies including Early Learning Centre India and Chicco (Ardo India Pvt. Ltd.), where compliance audit cycles shortened from quarterly to biannual after implementing her risk-prioritized testing matrix.
Dr. Kesri’s methodology remains rooted in empirical validation—not theoretical ideals. When evaluating magnet safety, she rejected proposals for blanket bans on neodymium magnets. Instead, her team conducted 4,200 swallow simulations using synthetic gastric tissue and measured magnetic flux density thresholds. They determined that magnets with surface field strength <100 mT (measured per ISO 8124-1 Annex H) posed negligible intestinal perforation risk—even when multiple units were ingested. This science-backed threshold now appears in IS 9873-1:2020 Amendment 2 (2023), allowing educational magnet sets like Magna-Tiles to remain legally marketable if labeled ‘Not for children under 5 years’ and tested to the 100 mT ceiling.
Her influence reaches into education policy: the National Council of Educational Research and Training (NCERT) adopted her age-band definitions in its 2022 ‘Guidelines for Selection of Learning Materials’, mandating that all government-distributed pre-primary kits meet IS 9873-1 mechanical and chemical limits. As of March 2024, 12.4 million children across 18 states have received BIS-compliant activity kits—replacing previously distributed sets that failed 63% of migration tests.
Dr. Kesri’s career exemplifies how rigorous science, operational pragmatism, and unwavering advocacy converge to protect children. She transformed toy safety from an afterthought into a quantifiable, auditable, and continuously improving discipline—one measurement, one standard, and one certified toy at a time.

Regulatory bodies worldwide consult her work. The ASEAN Centre for Product Standards cites her migration testing validation study in its 2023 ‘Harmonized Toy Testing Protocol’. Even the U.S. CPSC’s 2024 ‘Strategic Plan for Children’s Product Safety’ references her multi-tiered certification fee structure as a model for cost-equitable enforcement in developing economies.
For manufacturers, the message is unequivocal: compliance is not transactional—it is developmental. Dr. Kesri’s legacy lies in building systems where safety is engineered in, not inspected in; where every millimeter, ppm, and decibel serves a documented developmental need; and where standards evolve not just with technology, but with the lived reality of children’s play.
Her ongoing work with the Indian Academy of Pediatrics focuses on updating choking hazard thresholds using AI-assisted airway modeling—projected for publication in late 2024. This next phase promises to further narrow the gap between laboratory metrics and clinical outcomes, ensuring that future standards reflect not just what children can ingest—but what their developing physiology can withstand.
The numbers tell part of the story: 1,427 licensed manufacturers, 419 million USD in exports, 94.7% instrument concordance, and 35.8% non-conformance rate in 2023–24—all markers of a system maturing under scientific stewardship. But the true measure lies elsewhere: in fewer ER visits, safer classrooms, and toys that grow with children—not against them.
Dr. Rajnee Garg Kesri did not merely write standards. She translated childhood vulnerability into engineering precision, turning epidemiological data into dimensional tolerances, toxicological thresholds into polymer formulations, and regulatory intent into factory-floor action. That is her enduring contribution—and why her name belongs in every discussion about how societies protect their youngest members.
