Tattoo and body art supply retail operates under increasingly strict EU and UK chemical regulation, as well as age restrictions and professional verification requirements in some markets. Migrating to Shopify requires attention to product compliance data, age gating, and potentially restricting sales to verified professionals only.

Tattoo supply product categories

Tattoo inks: Pigmented inks for conventional tattooing, UV/blacklight inks. Subject to EU Regulation 2020/2081 (REACH) and UK equivalent. Certain azo dyes and pigments are now prohibited or restricted.
PMU (permanent makeup) pigments: Microblading and permanent makeup pigments. Subject to same regulation as tattoo inks from January 2022.
Tattoo needles: Single-use sterile needles. Configuration (round liner, magnum, flat), gauge, and count as variants.
Tattoo machines: Coil machines, rotary machines, cartridge machines. Voltage, stroke, and weight as metafields.
Power supplies and cables: Regulated and unregulated power supplies.
Aftercare products: Tattoo aftercare creams, balms, wraps. Cosmetic regulation applies.
Stencils and transfer supplies: Thermal transfer paper, stencil solution.
Hygiene and PPE: Gloves, barriers, surface disinfectants, sharps containers.
Body jewellery: Implant-grade titanium, surgical steel, PTFE body jewellery for piercings.

EU/UK tattoo ink regulation

Since January 2022, EU Regulation 2020/2081 (incorporated into UK REACH) restricted certain substances in tattoo inks and PMU pigments. The most commercially significant restrictions:

Pigment Blue 15:3 and Pigment Green 7: Restricted (maximum 25ppm in tattoo inks). Many popular blue and green inks required reformulation.
Certain azo dyes: Several red and yellow azo pigments are prohibited above threshold levels.
Preservatives (isothiazolinones): Restricted in ink formulations.

Before migration, verify all ink products comply with current regulation. Products with prohibited substances should not be migrated to Shopify without compliance review. Store compliance data as metafields:

product.metafields.tattoo.reach_compliant = "true"
product.metafields.tattoo.regulation_standard = "EU 2020/2081 / UK REACH"
product.metafields.tattoo.safety_data_sheet_url = "https://..."
product.metafields.tattoo.batch_certificate_url = "https://..."
product.metafields.tattoo.pigment_codes = "Pigment Black 11 / CI 77499"

Needle configuration variants

Tattoo needles have a specific configuration nomenclature (e.g. 1207RL = 12 gauge, 7-needle round liner). In Shopify:

Configuration as primary variant: 1003RL / 1005RL / 1007RL / 1009RL / 1014RL / 1207M1 / 1209M1 etc.
Pack size as secondary variant: 10-pack / 50-pack
Add descriptive metafield for customers unfamiliar with codes:

product.metafields.tattoo.needle_type = "Round Liner / Round Shader / Magnum / Curved Magnum / Flat"
product.metafields.tattoo.needle_count = "7"
product.metafields.tattoo.needle_gauge = "12"
product.metafields.tattoo.needle_configuration_code = "1207RL"
product.metafields.tattoo.taper = "Long / Medium / Short"
product.metafields.tattoo.sterile = "true"
product.metafields.tattoo.single_use = "true"

Tattoo machine metafields

product.metafields.tattoo.machine_type = "Coil / Rotary / Pen / Hybrid"
product.metafields.tattoo.stroke_mm = "3.5 / 4.0 / 4.5"
product.metafields.tattoo.voltage_range = "4-10V"
product.metafields.tattoo.weight_g = "120"
product.metafields.tattoo.cartridge_compatible = "true"
product.metafields.tattoo.needle_system = "Cartridge / Traditional"

Age restriction and professional verification

Tattoo supplies are typically sold to professional tattoo artists, not to the general public. Most suppliers restrict sales to verified professionals to:

Comply with age restrictions (18+ minimum)
Ensure products are used professionally (reducing liability)
Some jurisdictions require proof of professional licence or training

In Shopify, implement professional verification using customer tags:

Require a professional registration application form before account approval
Tag approved professional accounts with professional-verified
Use Locksmith or customer account apps to restrict access to the store to verified professionals only
Age verification app as a baseline for all visitors

Body jewellery compliance

Implant-grade body jewellery must meet material safety standards. In the UK, the Personal Protective Equipment Regulations and Nickel Directive apply to body jewellery:

product.metafields.tattoo.material = "Implant-grade titanium ASTM F136 / ASTM F138 surgical steel / PTFE"
product.metafields.tattoo.implant_grade = "true"
product.metafields.tattoo.nickel_compliant = "true"
product.metafields.tattoo.gauge_mm = "1.2 / 1.6 / 2.0"
product.metafields.tattoo.internal_vs_external_thread = "Internal / Externally threaded / Threadless"

Post-migration checklist for tattoo supply stores

All ink products reviewed against EU 2020/2081 / UK REACH compliance before migration
Safety data sheet URLs stored as metafields for all inks and pigments
Needle configuration codes and descriptive names as metafields
Age verification app installed (18+ minimum)
Professional verification workflow implemented (registration form + customer tag)
Body jewellery: implant-grade certification and material metafields populated
Sharps containers and clinical waste products: check Shopify's acceptable use policy
