Thailand Proposes New Standard for Certain Food Contact Plastics
Thailand is proposing a mandatory standard for food contact materials and articles made of thermoset plastics derived from formaldehyde. Comments for the draft standard are accepted until April 14, 2019.
SAFEGUARDS | Hardgoods NO. 039/19
In February 2019, the World Trade Organization (WTO) circulated a notification announcing a draft standard from Thailand for food contact materials and articles (FCMs) manufactured from thermoset plastics with the polymerization of formaldehyde. This draft standard from the Thai Industrial Standards Institute (TISI), designated as TIS 2921-25XX(20XX) and attached to WTO document number 19-0845, is a mandatory standard for FCMs made from the following resins:
- Melamine-formaldehyde (MF)
- Melamine-urea-formaldehyde (MUF)
- Urea-formaldehyde (UF)
The draft standard contains a number of important elements. These include, inter alia, the following:
- Scope and definitions
- Physical requirements
- Requirements for overall migration (see Table 1)
- Requirements for the specific migration of formaldehyde, melamine and nine heavy metals (see Tables 1 and 2) – these nine metals and their limits are identical to those under Regulation (EU) 2017/752, amending Regulation (EU) 10/2011 on ‘Food Contact Plastics’, in the European Union (EU) (Safeguard 75/17)
- Providing procedures and applicable analytical techniques for the test parameters in points (ii), (iii) and (iv) above
- Requirements for marking and labeling, including the use of the food contact safe symbol (a plate with a fork and spoon symbol, Appendix B) for compliant products
- Sampling criteria (Appendix A)
According to the WTO document, the final date for comments is April 14, 2019 (60 days after notification). The notification has not specified a proposed date of adoption or entry into force.
Highlights of the requirements for points (iii) and (iv) above are summarized in Tables 1 and 2 below.
|1||Overall migration||3% Acetic acid||EN 1186 Parts 3 and 9||≤ 10 mg/dm²|
|2||Specific migration of heavy metals||3% Acetic acid||Article 8.4||See Table 2|
|3||Specific migration of formaldehyde||3% Acetic acid||Article 8.5||≤ 15 mg/kg|
|4||Specific migration of melamine||3% Acetic acid||Article 8.6||≤ 2.5 mg/kg|
Table 1. Requirements for overall migration and the specific migration of heavy metals, formaldehyde and melamine
|Item||Heavy Metal||Requirement for specific migration|
|1||Aluminum||≤ 1 mg/kg|
|2||Barium||≤ 1 mg/kg|
|3||Cobalt||≤ 0.05 mg/kg|
|4||Copper||≤ 5 mg/kg|
|5||Iron||≤ 48 mg/kg|
|6||Lithium||≤ 0.6 mg/kg|
|7||Manganese||≤ 0.6 mg/kg|
|8||Nickel||≤ 0.02 mg/kg|
|9||Zinc||≤ 5 mg/kg|
