Changde, Hunan, China – September 28, 2026

A delegation from a Japanese wellness brand visited Hunan Pinliu Biotechnology’s headquarters in Changde, Hunan this week to evaluate the company as an OEM/ODM partner for custom steam eye masks. The one-day visit covered the corporate showroom, the enterprise patent wall, hands-on product evaluation, and a working session on private-label specifications — a milestone in Pinliu’s continued expansion into East Asia’s most quality-demanding market.

1. The showroom tour: a decade of self-heating expertise

The visit began in Pinliu’s corporate showroom, where the delegation followed the company’s development from its founding in 2015 to today’s dual-base manufacturing platform. The tour traced the evolution of Pinliu’s self-heating product lines — from the flagship steam eye mask series to warming patches, moxibustion patches, and eye-care products.

The delegation paid close attention to the enterprise qualification wall, which displays the company’s 23 patents — including invention patents for temperature-controlled steam eye masks and self-heating herbal warming products — alongside certifications such as ISO 9001, ISO 13485, FDA, BSCI and RoHS. For a buyer preparing to launch in the Japanese market, documented intellectual property and third-party audits carry particular weight: Japanese retail partners routinely require this level of supply-chain transparency before onboarding a new manufacturer.

Hands-on product evaluation

From the showroom, the visit moved to product evaluation. Pinliu’s product team presented sample units from the steam eye mask platform — including the C-type contoured design, fragrance variants, and temperature-curve options — and walked the delegation through the structural details that differentiate the products: heating-layer formulation, skin-contact materials, and ear-loop or contour-fit ergonomics.

The Japanese guests examined the samples in detail, asking questions that reflected the standards of their home market: heat-up timing, peak temperature stability across a production batch, steam duration, and material breathability. Pinliu’s team answered with batch-level test data, including temperature-curve records from the company’s in-house testing process.

The day concluded with a closed-door working session between both teams. The discussion centered on the delegation’s core requirement: a custom steam eye mask tailored for the Japanese market, covering:

Heating profile:target temperature range and duration, tuned to Japanese consumer expectations for gentle, consistent warmth.

Fragrance:scent options consistent with the Japanese wellness aesthetic, alongside fragrance-free variants.

Shape and materials:contoured fit options and skin-contact fabrics that meet Japan’s stringent skin-safety expectations.

Private-label packaging:retail-ready design, Japanese-language labeling support, and export documentation.

Both sides agreed to move into the sample and specification stage with technical documentation. The delegation departed with a clear picture of Pinliu’s production scale: a 50,000 m² smart manufacturing base in Changde, a 7,000 m² Guangzhou facility, and a daily output exceeding 5 million pieces.

Japan is one of the most mature steam eye mask markets in the world, with consumers who expect precise temperature control, reliable safety, and refined packaging. Earning a custom-manufacturing mandate from a Japanese brand is therefore one of the strongest validations a wellness OEM/ODM factory can receive — it signals that the factory’s quality system has passed one of the industry’s most demanding filters.

For Pinliu, the visit extends a pattern of international brand partnerships built on on-site verification: buyers walk the lines, review the data, and then commit.

5. What happens next

Following the visit, both teams will move through the standard OEM/ODM onboarding sequence: sample submission with technical specification sheets, client-side evaluation, specification lock, and trial production. Pinliu’s export team will support the delegation with regulatory documentation, including MSDS and material safety data required for import into Japan.

Brands interested in visiting the Changde facility or requesting custom steam eye mask samples can contact Pinliu’s international sales team directly.

6. Meet Pinliu at the 140th Canton Fair

International buyers will have the next opportunity to meet Pinliu in person at the 140th Canton Fair, taking place October 31 – November 4, 2026 in Guangzhou, China. The Pinliu team will present its full wellness portfolio – steam eye masks, warming patches, moxibustion patches, and new products including the burst-bead warm neck patch – with live demonstrations and OEM/ODM consultations on site.

Visitors are welcome to schedule an appointment in advance through Pinliu’s international sales team to ensure dedicated time with the company’s product specialists.
