Mothball

Modern mothballs primarily use Paradichlorobenzene (PDB) or Naphthalene. PDB is often preferred in professional sourcing because it is less flammable and has a slightly less persistent odor than Naphthalene. You must verify the purity levels (typically >99%) to ensure effectiveness. For eco-conscious markets, consider natural alternatives like Camphor or Cedarwood oil-infused blocks, which are increasingly popular in the EU and North American retail sectors.

As a chemical pesticide/repellent, mothballs must adhere to strict regulations. Ensure products are compliant with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the EU market and EPA (Environmental Protection Agency) registration for the US. Packaging must feature GHS (Globally Harmonized System) labeling, including clear hazard pictograms, 'Keep out of reach of children' warnings, and active ingredient percentages.

Mothballs sublimate (turn from solid to gas), so airtight, high-barrier packaging is critical to prevent weight loss and potency reduction during transit. For retail, look for child-resistant packaging (CRP) and perforated individual sachets that allow the gas to escape slowly while preventing direct skin contact. Ensure the outer cartons are moisture-proof to maintain structural integrity in humid shipping containers.

The primary KPI is the sublimation rate; high-quality mothballs should provide protection for 3 to 6 months in a sealed environment. Other factors include residue-free performance (ensuring no oily stains are left on fabrics) and odor neutrality after aeration. Request evaporation stability test reports from suppliers to confirm the longevity of the product.

Mothballs are often classified as Class 4.1 (Flammable Solids) or Class 9 (Miscellaneous Dangerous Goods) depending on the concentration and chemical type. You must ensure the supplier provides a valid MSDS (Material Safety Data Sheet) and a UN38.3 Test Report if applicable. Use freight forwarders experienced in DG (Dangerous Goods) handling to avoid customs seizures or fines at the port of entry.

Prioritize Audited Suppliers on Made-in-China.com who have undergone on-site inspections. Check for ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) certifications. Review their export history to your target country to ensure they understand your local chemical import laws and labeling requirements.

Focus on volume-based pricing tiers; chemical manufacturing costs drop significantly at higher tonnages. Negotiate for customized packaging (OEM) included in the unit price for orders exceeding 5,000 units. Always request a pre-shipment sample from the actual production batch to conduct a purity test before the final balance payment is released.

Utilize Secured Trading services offered by Made-in-China.com to protect your payment until the goods are confirmed. For chemical products, it is highly recommended to hire a third-party inspection agency (like SGS or Intertek) to perform a Random Sampling Inspection before loading, focusing on weight accuracy, chemical composition, and packaging seal integrity.
