What moves, why the same formula behaves differently, and how to requalify. https://gzcosmeticslab.com/blog/cosmetics-landed-cost-us-import https://gzcosmeticslab.com/blog/cosmetics-landed-cost-us-import Mon, 07 Sep 2026 12:00:00 GMT US duty on skincare and colour cosmetics under HTS 3304 is Free, yet landed cost went up in 2026. The reason is procedural: every parcel of 800 dollars or less now needs a customs entry. How to model landed cost so the number survives the next rate change. https://gzcosmeticslab.com/blog/cosmetic-claims-compliance-us-eu-china https://gzcosmeticslab.com/blog/cosmetic-claims-compliance-us-eu-china Thu, 03 Sep 2026 12:00:00 GMT A single efficacy claim can turn a cosmetic into an unapproved drug in the US, an illegal claim in the EU, and a filing trigger in China. The words on the label decide the regulatory route — not the ingredient list. What each market polices, and how to word claims that stay cosmetic. https://gzcosmeticslab.com/blog/banned-cosmetic-ingredients-eu https://gzcosmeticslab.com/blog/banned-cosmetic-ingredients-eu Wed, 02 Sep 2026 12:00:00 GMT The EU's long banned-ingredient list is not what forces a reformulation. Four instruments do: the vitamin A cap, 82 fragrance allergens, the D5/D6 siloxane limit, and the zinc pyrithione ban. What each changes, what replaces it, and the 45-60 day timeline. https://gzcosmeticslab.com/blog/makeup-remover-cleansing-balm-oem https://gzcosmeticslab.com/blog/makeup-remover-cleansing-balm-oem Mon, 31 Aug 2026 12:00:00 GMT Makeup remover OEM splits into three removal mechanisms, not three textures: micellar water, cleansing oil and cleansing balm each fail differently. Melt point, emulsifier load and peroxide value decide your sampling window, not the ingredient list. https://gzcosmeticslab.com/blog/body-care-manufacturer-philippines https://gzcosmeticslab.com/blog/body-care-manufacturer-philippines Sat, 29 Aug 2026 12:00:00 GMT Choosing a body care manufacturer for the Philippines: why you cannot hold your own CPN, how per-variant notification multiplies across a body range, and what it costs. https://gzcosmeticslab.com/blog/fragrance-perfume-oem https://gzcosmeticslab.com/blog/fragrance-perfume-oem Fri, 28 Aug 2026 12:00:00 GMT Perfume minimums start at 1,000 bottles per SKU, lower than skincare, but alcohol-based fragrance ships as UN1266 Class 3 dangerous goods and the EU allergen list expanded to 82 substances on 31 July 2026. How to sequence a fragrance brief. https://gzcosmeticslab.com/blog/contract-cosmetic-packaging https://gzcosmeticslab.com/blog/contract-cosmetic-packaging Fri, 28 Aug 2026 12:00:00 GMT Your MOQ is quoted per format, not per formula. Bottles, jars, tubes, sheets and sets each carry their own minimum, their own filling line and their own compatibility risk. How to sequence packaging decisions before tooling money moves. https://gzcosmeticslab.com/blog/soothing-sensitive-skin-oem https://gzcosmeticslab.com/blog/soothing-sensitive-skin-oem Thu, 27 Aug 2026 12:00:00 GMT In soothing skincare the regulatory risk sits in the verb, not the percentage. Menthol and capsaicin tiers, arnica and tea tree claim limits, centella basis, and the EU 655/2013 criteria that bite hardest. https://gzcosmeticslab.com/blog/hydrating-barrier-repair-oem https://gzcosmeticslab.com/blog/hydrating-barrier-repair-oem Wed, 26 Aug 2026 12:00:00 GMT A higher ceramide percentage is the wrong lever. Barrier performance follows the lipid ratio, not the headline number. Ceramide grades, centella basis, HA ceilings and claim limits. https://gzcosmeticslab.com/blog/freeze-dried-serum-oem https://gzcosmeticslab.com/blog/freeze-dried-serum-oem Tue, 25 Aug 2026 12:00:00 GMT A lyophilised serum quote is really a quote for machine hours, and the formula's collapse temperature sets how many. Tg′ vs Tc, why published values shift with heating rate, USP <921> moisture methods, MOQ 3,000–5,000 sets, 50–70 days. https://gzcosmeticslab.com/blog/anti-aging-firming-skincare-oem https://gzcosmeticslab.com/blog/anti-aging-firming-skincare-oem Mon, 24 Aug 2026 12:00:00 GMT Anti-aging OEM quotes differ tenfold on the same 3% peptide because trade-solution and pure-peptide bases are not the same number. Dosage tiers, claim limits and lead times. https://gzcosmeticslab.com/blog/cosmetic-manufacturing-companies https://gzcosmeticslab.com/blog/cosmetic-manufacturing-companies Thu, 20 Aug 2026 12:00:00 GMT Lists of cosmetic manufacturing companies come from industry codes, paid directories and facility registers.
